Continuous involuntary sustained muscle contraction which is often a manifestation of BASAL GANGLIA DISEASES. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from MUSCLE SPASTICITY. (From Adams et al., Principles of Neurology, 6th ed, p73)
Studies comparing two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)

Regulation of chamber-specific gene expression in the developing heart by Irx4. (1/8990)

The vertebrate heart consists of two types of chambers, the atria and the ventricles, which differ in their contractile and electrophysiological properties. Little is known of the molecular mechanisms by which these chambers are specified during embryogenesis. Here a chicken iroquois-related homeobox gene, Irx4, was identified that has a ventricle-restricted expression pattern at all stages of heart development. Irx4 protein was shown to regulate the chamber-specific expression of myosin isoforms by activating the expression of the ventricle myosin heavy chain-1 (VMHC1) and suppressing the expression of the atrial myosin heavy chain-1 (AMHC1) in the ventricles. Thus, Irx4 may play a critical role in establishing chamber-specific gene expression in the developing heart.  (+info)

Gamma-Actinin, a new regulatory protein from rabbit skeletal muscle. I. Purification and characterization. (2/8990)

A new regulatory protein which we have designated as gamma-actinin has been isolated from native thin filaments of rabbit skeletal muscle. Depolymerized native thin filaments were fractionated by salting out with ammonium sulfate, and the precipitates obtained at 40--60% ammonium sulfate saturation were further subjected to DEAE-Sephadex and Sephadex G-200 column chromatography. The purified gamma-actinin was shown to have a chain weight of 35,000 daltons and had a strong inhibitory action on the polymerization of G-actin. The results of amino acid analysis indicated a unique amino acid composition of gamma-actinin as compared with other structural proteins of muscle. Non-polar and neutral amino acid residues were abundant. One cysteine residue was contained per one molecule of gamma-actinin and played a critical role in the maintenance of the inhibitory activity. Pelleting of gamma-actinin with F-actin showed that gamma-actinin binds to F-action.  (+info)

Connectin, an elastic protein from myofibrils. (3/8990)

The elastic protein isolated from myofibrils of chicken skeletal muscle was compared with extracellular non-collagenous reticulin prepared from chicken liver and skeletal muscle. The amino acid compositions of these proteins were similar except that their contents of Phe, Leu, Cys/2, and Hyp were different. The impregnations of the elastic protein and reticulin with silver were also different. The reticulin was not at all elastic. It also differed from reticulin in solubility and antigenicity. It is proposed to call the intracellular elastic protein connectin.  (+info)

Model-independent analysis of the orientation of fluorescent probes with restricted mobility in muscle fibers. (4/8990)

The orientation of proteins in ordered biological samples can be investigated using steady-state polarized fluorescence from probes conjugated to the protein. A general limitation of this approach is that the probes typically exhibit rapid orientational motion ("wobble") with respect to the protein backbone. Here we present a method for characterizing the extent of this wobble and for removing its effects from the available information about the static orientational distribution of the probes. The analysis depends on four assumptions: 1) the probe wobble is fast compared with the nanosecond time scale of its excited-state decay; 2) the orientational distributions of the absorption and emission transition dipole moments are cylindrically symmetrical about a common axis c fixed in the protein; 3) protein motions are negligible during the excited-state decay; 4) the distribution of c is cylindrically symmetrical about the director of the experimental sample. In a muscle fiber, the director is the fiber axis, F. All of the information on the orientational order of the probe that is available from measurements of linearly polarized fluorescence is contained in five independent polarized fluorescence intensities measured with excitation and emission polarizers parallel or perpendicular to F and with the propagation axis of the detected fluorescence parallel or perpendicular to that of the excitation. The analysis then yields the average second-rank and fourth-rank order parameters ( and ) of the angular distribution of c relative to F, and and , the average second-rank order parameters of the angular distribution for wobble of the absorption and emission transition dipole moments relative to c. The method can also be applied to other cylindrically ordered systems such as oriented lipid bilayer membranes and to processes slower than fluorescence that may be observed using longer-lived optically excited states.  (+info)

Aging-specific expression of Drosophila hsp22. (5/8990)

hsp22 is among the least abundantly expressed Drosophila heat shock (hs) genes during both development and heat stress. In contrast, hsp22 was found to be the most abundantly expressed hs gene during Drosophila aging. During aging, hsp22 RNA was induced 60-fold in the head, with somewhat lower level induction in abdomen and thorax. Induction of the other hs gene RNAs was 150-fold, with particularly abundant expression in eye tissue. Aging-specific induction of hsp22 was reproduced by hsp22:lacZ fusion reporter constructs in transgenic flies. Analysis of specific promoter mutations in transgenic flies indicated that functional heat shock response elements are required for hsp22 induction during aging. Finally, comparison of hsp22 RNA and protein expression patterns suggests that aging-specific expression of hsp22 is regulated at both the transcriptional and the posttranscriptional levels. Aging-specific induction of hsp22 is discussed with regard to current evolutionary theories of aging.  (+info)

SNAP-23 participates in SNARE complex assembly in rat adipose cells. (6/8990)

SNARE proteins are required for vesicle docking and fusion in eukaryotic cells in processes as diverse as homotypic membrane fusion and synaptic vesicle exocytosis [SNARE stands for SNAP receptor, where SNAP is soluble NSF attachment protein]. The SNARE proteins syntaxin 4 and vesicle-associated membrane protein (VAMP) 2/3 also participate in the insulin-stimulated translocation of GLUT4 from intracellular vesicles to the plasma membrane in adipose cells. We now report the molecular cloning and characterization of rat SNAP-23, a ubiquitously expressed homologue of the essential neuronal SNARE protein SNAP-25 (synaptosomal-associated protein of 25 kDa). Rat SNAP-23 is 86% and 98% identical respectively to human and mouse SNAP-23. Southern blot analysis reveals that the rat, mouse and human SNAP-23 genes encode species-specific isoforms of the same protein. Co-immunoprecipitation of syntaxin 4 and SNAP-23 shows association of these two proteins in rat adipose cell plasma membranes, and insulin stimulation does not alter the SNAP-23/syntaxin 4 complex. In addition, we demonstrate for the first time the participation of SNAP-23, along with syntaxin 4 and VAMP2/3, in the formation of 20S SNARE complexes prepared using rat adipose cell membranes and recombinant alpha-SNAP and NSF proteins. The stoichiometry of the SNARE complexes formed is essentially identical using membranes from either unstimulated or insulin-stimulated adipose cells. These data demonstrate that rat SNAP-23 associates with syntaxin 4 before insulin stimulation and is present in the SNARE complexes known to mediate the translocation of GLUT4 from intracellular vesicles to the plasma membrane of rat adipose cells.  (+info)

Tumour necrosis factor-alpha regulates expression of the CCAAT-enhancer-binding proteins (C/EBPs) alpha and beta and determines the occupation of the C/EBP site in the promoter of the insulin-responsive glucose-transporter gene in 3T3-L1 adipocytes. (7/8990)

We have demonstrated previously that treatment of 3T3-L1 adipocytes with tumour necrosis factor-alpha (TNF) results in a rapid (4 h) and significant (75-80%) reduction in the rate of transcription of the GLUT4 gene. Control of GLUT4 gene transcription has been suggested at least in part to reside with the CCAAT-enhancer-binding protein (C/EBP) family (alpha, beta and delta isoforms) of transcription factors. Using electrophoretic mobility shift assays, we have examined the ability of TNF to alter the occupation of the C/EBP site in the GLUT4 promoter. The data suggest that in fully differentiated adipocytes the C/EBP site is a ligand for predominantly alpha/alpha homodimers; however, after exposure to TNF, a shift in occupancy of the site occurs and the ligands become alpha/beta heterodimers and beta/beta homodimers. Partner selection in dimer formation appears to be controlled by selective translocation of the beta-isoform from the cytosol to the nucleus after exposure of the cells to TNF.  (+info)

Intestinal trefoil factor binds to intestinal epithelial cells and induces nitric oxide production: priming and enhancing effects of mucin. (8/8990)

Intestinal trefoil factor (ITF or TFF3), NO and epithelium-associated mucin have important roles in sustaining mucosal integrity in the gastrointestinal tract. In the present study we examined ITF-binding molecules on IEC-18 cells (an intestinal epithelial cell line) with the use of flow cytometry and localized these molecules on the cell surface by confocal microscopy. Furthermore, we studied the interaction of mucin and ITF and their co-operative effect on NO production by the epithelium. Stimulation of cells with mucin (5 mg/ml) for 90 min resulted in a 5-fold increase in ITF binding. Treatment of IEC-18 cells with actinomycin D or cycloheximide attenuated mucin-enhanced ITF binding. Ligand blot analysis confirmed the induction of ITF-binding protein in IEC-18 cells by mucin. These results indicate that transcriptional and translational mechanisms are involved in the effect of mucin. Treatment with ITF overnight resulted in a low level of nitrite production by the cells, a 5-fold increase over control, in a concentration-dependent manner. ITF-induced NO production was attenuated by 1400W, a selective type II nitric oxide synthase (NOS2) inhibitor. By immunoblotting we found that NOS2 was up-regulated by ITF treatment. Priming IEC-18 cells with mucin for 90 min enhanced the effect of ITF on NO production, suggesting that the up-regulation of ITF-binding molecules by mucin might be physiologically relevant. Taken together, these observations indicate (1) that ITF-binding molecules that are up-regulated by mucin exist on the intestinal epithelial surface, and (2) that ITF modulates epithelial NO production via the NOS2 pathway, which is enhanced by mucin.  (+info)

Preservation of skeletal muscle mass is of great importance for maintaining both metabolic health and functional capacity. Muscle mass maintenance is regulated by the balance between muscle protein breakdown and synthesis rates. Both muscle protein breakdown and synthesis rates have been shown to be highly responsive to physical activity and food intake. Food intake, and protein ingestion in particular, directly stimulates muscle protein synthesis rates. The postprandial muscle protein synthetic response to feeding is regulated on a number of levels, including dietary protein digestion and amino acid absorption, splanchnic amino acid retention, postprandial insulin release, skeletal muscle tissue perfusion, amino acid uptake by muscle, and intramyocellular signaling. The postprandial muscle protein synthetic response to feeding is blunted in many conditions characterized by skeletal muscle loss, such as aging and muscle disuse. Therefore, it is important to define food characteristics that modulate
Purpose: Erythropoietin (EPO) is a renal cytokine that is primarily involved in hematopoiesis while also playing a role in non-hematopoietic tissues expressing the EPO-receptor (EPOR). The EPOR is present in human skeletal muscle. In mouse skeletal muscle, EPO stimulation can activate the AKT serine/threonine kinase 1 (AKT) signaling pathway, the main positive regulator of muscle protein synthesis. We hypothesized that a single intravenous EPO injection combined with acute resistance exercise would have a synergistic effect on skeletal muscle protein synthesis via activation of the AKT pathway.Methods: Ten young (24.2 ± 0.9 years) and 10 older (66.6 ± 1.1 years) healthy subjects received a primed, constant infusion of [ring-13C6] L-phenylalanine and a single injection of 10,000 IU epoetin-beta or placebo in a double-blind randomized, cross-over design. 2 h after the injection, the subjects completed an acute bout of leg extension resistance exercise to stimulate skeletal muscle protein synthesis
TY - JOUR. T1 - Rapamycin administration in humans blocks the contraction-induced increase in skeletal muscle protein synthesis. AU - Drummond, Micah J.. AU - Fry, Christopher. AU - Glynn, Erin L.. AU - Dreyer, Hans C.. AU - Dhanani, Shaheen. AU - Timmerman, Kyle L.. AU - Volpi, Elena. AU - Rasmussen, Blake. PY - 2009. Y1 - 2009. N2 - Muscle protein synthesis and mTORC1 signalling are concurrently stimulated following muscle contraction in humans. In an effort to determine whether mTORC1 signalling is essential for regulating muscle protein synthesis in humans, we treated subjects with a potent mTORC1 inhibitor (rapamycin) prior to performing a series of high-intensity muscle contractions. Here we show that rapamycin treatment blocks the early (1-2 h) acute contraction-induced increase (∼40%) in human muscle protein synthesis. In addition, several downstream components of the mTORC1 signalling pathway were also blunted or blocked by rapamycin. For instance, S6K1 phosphorylation (Thr421/Ser424) ...
Age-related muscle wasting (sarcopenia) is accompanied by a loss of strength which can compromise the functional abilities of the elderly. Muscle proteins are in a dynamic equilibrium between their respective rates of synthesis and breakdown. It has been suggested that age-related sarcopenia is due to: i) elevated basal-fasted rates of muscle protein breakdown, ii) a reduction in basal muscle protein synthesis (MPS), or iii) a combination of the two factors. However, basal rates of muscle protein synthesis and breakdown are unchanged with advancing healthy age. Instead, it appears that the muscles of the elderly are resistant to normally robust anabolic stimuli such as amino acids and resistance exercise. Ageing muscle is less sensitive to lower doses of amino acids than the young and may require higher quantities of protein to acutely stimulate equivalent muscle protein synthesis above rest and accrue muscle proteins. With regard to dietary protein recommendations, emerging evidence suggests ...
BACKGROUND. Systemic inflammation and muscle wasting are highly prevalent and coexist in patients on maintenance hemodialysis (MHD). We aimed to determine the effects of systemic inflammation on skeletal muscle protein metabolism in MHD patients. METHODS. Whole body and skeletal muscle protein turnover were assessed by stable isotope kinetic studies. We incorporated expressions of E1, E214K, E3αI, E3αII, MuRF-1, and atrogin-1 in skeletal muscle tissue from integrin β1 gene KO CKD mice models. RESULTS. Among 129 patients with mean (± SD) age 47 ± 12 years, 74% were African American, 73% were male, and 22% had diabetes mellitus. Median high-sensitivity C-reactive protein (hs-CRP) concentration was 13 (interquartile range 0.8, 33) mg/l. There were statistically significant associations between hs-CRP and forearm skeletal muscle protein synthesis, degradation, and net forearm skeletal muscle protein balance (P , 0.001 for all). The associations remained statistically significant after ...
BACKGROUND: The progressive loss of skeletal muscle mass with aging is attributed to a disruption in the regulation of skeletal muscle protein turnover. OBJECTIVE: We investigated the effects on whole-body protein balance and mixed-muscle protein synthesis rates of the ingestion of carbohydrate with or without protein and free leucine after simulated activities of daily living. DESIGN: Eight elderly (75 +/- 1 y) and 8 young (20 +/- 1 y) lean men were randomly assigned to 2 crossover experiments in which they consumed either carbohydrate (CHO) or carbohydrate plus protein and free leucine (CHO+Pro+Leu) after performing 30 min of standardized activities of daily living. Primed, continuous infusions with L-[ring-13C6]phenylalanine and L-[ring-2H2]tyrosine were applied, and blood and muscle samples were collected to assess whole-body protein turnover and the protein fractional synthetic rate in the vastus lateralis muscle over a 6-h period. RESULTS: Whole-body phenylalanine and tyrosine flux were ...
An abundant supply of amino acids enhances the metabolic effect of exercise on muscle protein. Am. J. Physiol. 273 (Endocrinol. Metab. 36): El22-E129, 1997. -Six normal untrained men were studied during the intravenous infusion of a balanced amino acid mixture (-0.15 g. kg-l. h-l for 3 h) at rest and after a leg resistance exercise routine to test the influence of exercise on the regulation of muscle protein kinetics by hyperaminoacidemia. Leg muscle protein kinetics and transport of selected amino acids (alanine, phenylalanine, leucine, and lysine) were isotopically determined using a model based on arteriovenous blood samples and muscle biopsy. The intravenous amino acid infusion resulted in comparable increases in arterial amino acid concentrations at rest and after exercise, whereas leg blood flow was 64 +/- 5% greater after exercise than at rest. During hyperaminoacidemia, the increases in amino acid transport above basal were 30-100% greater after exercise than at rest. Increases in muscle ...
We have previously shown that non-specific blockade of the cyclooxygenase (COX) enzymes in skeletal muscle eliminates the normal increase in muscle protein synthesis following resistance exercise. The current study tested the hypothesis that this COX-mediated increase in postexercise muscle protein synthesis is specifically regulated by the COX-2 isoform. Sixteen males (23 ± 1 yr, 177 ± 2 cm, 81.5 ± 3.4 kg) were randomly assigned to one of two groups that received three doses of either a specific COX-2 inhibitor (celecoxib; 200 mg per dose, 600 mg total) or a placebo during the 24 hours following a single bout of resistance exercise with the knee extensors. Skeletal muscle fractional synthesis rate (FSR) was measured at rest and 24 hours postexercise using a primed constant infusion of [2H5]phenylalanine coupled with muscle biopsies of the vastus lateralis. Mixed muscle FSR was increased following exercise to a greater extent (206%, P,0.05) in the COX-2 group (0.052 ± 0.014 %Ih) as compared ...
There were 2 primary goals of this work. The first was to develop a minimally invasive method for measuring integrated rates of skeletal muscle protein synthesis over a period of days to weeks based on a single blood measurement - i.e., without the need for a physical sample of the tissue. Muscle biopsies are not likely to be widely used in the clinical setting, so a blood test of muscle protein synthesis rates that could be monitored over time would be attractive for drug development, as well as clinical management of disorders of muscle, including sarcopenia and cachexia. Because changes in muscle protein synthesis rates have been shown to occur rapidly in response to anabolic therapies and to predict subsequent changes in muscle mass, strength, and performance (5, 8-10), the availability of a blood test for skeletal muscle protein synthesis rates would greatly simplify translational drug development and monitoring of treatment efficacy in this growing, unmet medical need.. We describe here an ...
It is thought that the production of muscle protein after a meal in response to consuming protein and/or amino acids is impaired in the elderly compared to the young. Also, consuming carbohydrates at the same time increases secretion of the hormone insulin and increases muscle protein production in the young. However, it is unclear how the elderly respond to the combined intake of protein and carbohydrates. Likewise, consuming the amino acid leucine may also increase muscle protein production. Adding carbohydrate or leucine to protein may represent effective strategies to overcome the impaired muscle protein production in the elderly. This study consists of three substudies. The aim of the first study is to determine if the response to combined protein and carbohydrate intake is different between young and elderly men. The aim of the second study is to investigate whether consuming carbohydrate as well increases muscle protein production in elderly men. The aim of the third study is to examine ...
Muscle protein breakdown (MPB) is an important metabolic component of muscle remodeling, adaptation to training, and increasing muscle mass. Degradation of muscle proteins occurs via the integration of three main systems-autophagy and the calpain and ubiquitin-proteasome systems. These systems do not operate independently, and the regulation is complex. Complete degradation of a protein requires some combination of the systems. Determination of MPB in humans is technically challenging, leading to a relative dearth of information. Available information on the dynamic response of MPB primarily comes from stable isotopic methods with expression and activity measures providing complementary information. It seems clear that resistance exercise increases MPB, but not as much as the increase in muscle protein synthesis. Both hyperaminoacidemia and hyperinsulinemia inhibit the post-exercise response of MPB. Available data do not allow a comprehensive examination of the mechanisms behind these responses. ...

TY - JOUR. T1 - Reduced synthesis of muscle proteins in chronic renal failure. AU - Adey, Deborah. AU - Kumar, Rajiv. AU - McCarthy, James T.. AU - Sreekumaran Nair, K.. PY - 2000/2. Y1 - 2000/2. N2 - Muscle wasting and weakness occur frequently in patients with chronic renal failure. The mechanism(s) by which these abnormalities occur is unclear. We hypothesized that such findings were due to defective muscle protein synthesis. We measured synthetic rates of mixed muscle proteins, myosin heavy chain, and mitochondrial proteins in serial muscle biopsy samples during a continuous infusion of L[1-13C] leucine from 12 patients with chronic renal failure and 10 healthy control subjects under identical study conditions. Patients with chronic renal failure have significantly lower synthetic rates of mixed muscle proteins and myosin heavy chain (27 and 37% reductions, respectively, P , 0.05 and P , 0.02). Significant declines in the synthetic rates of muscle mitochondrial protein (27%) (P , 0.05), ...
The purpose of this investigation was to examine the effects of training either once or three times/day on the principal stages of skeletal muscle. The experiments were carried out on male albino rats fed either 3 or 5 times/day a diet containing 20% protein. Experimental animals swam either once or 3 times/day, 6 days/week for 10 weeks with weights attached. The total duration of daily activity was equal for both groups and at 10 weeks each animal was swimming for 60 min/day with 3% of his body weight attached. All the animals were examined at rest after the 10-week training programs. The adequacy of the weight-loading and training schedules was estimated by body weight dynamics and such energy metabolites as creatine phosphate and glycogen. Skeletal muscle RNA and protein synthesis were studied by means of 14C-orotic acid and 14C-leucine incorporation, respectively. Quadriceps and gastrocnemius muscles were used for analysis in all experiments. It was found that the increase in the number of daily
Optimal muscle protein synthesis requires a pulsatile increase in branch-chain amino acids (particularly leucine) with or without concomitant pulses in insulin levels. Pancreatic substrate clamp studies have demonstrated that insulin and branch-chain amino acids independently increase muscle synthesis with the effects of both being additive [45, 46]. Animal data demonstrates that muscle protein synthesis following a meal is rapid (within 30 min) and sustained for about 2 h but then declines toward baseline in parallel with the postprandial changes in circulating insulin and amino acids [34, 47]. Bohe and colleagues measured the latency and duration of the stimulation of human muscle protein synthesis during a continuous infusion of amino acids [48]. The rate of muscle protein synthesis increased after 30 min and reached a peak at 2 h rapidly returning to basal levels by 4 h despite continuous amino acid availability. In healthy individuals at rest, muscle protein synthesis displays a saturable ...

It is well established that consuming protein and/or amino acids is necessary to stimulate post-exercise protein synthesis, thus creating a positive protein balance1-3. In accordance, dietary protein administration with or without carbohydrate ingestion before, during, and/or immediately after exercise has been shown to stimulate net muscle protein accretion during post-exercise recovery which is needed for the accrual of muscle mass.. Most of the research in this area examined the effect of food intake on the muscle protein synthesis response to exercise in an overnight fasted state2,4,5. It is reasonable to assume the limited availability of amino acids prevents a substantial rise in post-exercise muscle protein synthesis rate. This post-absorptive (fasted) condition differs from normal everyday practice in which sport activities are often performed in postprandial (after eating) conditions, such as in the evening. A study evaluated the efficacy of protein ingestion immediately after exercise ...

Many protein and amino acid supplements are touted as being able to maximize the gains achieved from resistance exercise by preventing muscle protein catabolism and stimulating anabolism. If effective, such supplements would be useful not only for athletes and for those trying to increase their fat free mass, but also for patients recovering from injuries or burns and for the prevention of aging-associated muscle loss. It has been shown that intravenous infusion or oral administration of complete mixtures of amino acids has a positive effect on muscle protein synthesis and net muscle anabolism following exercise. Since nonessential amino acids are synthesized by the body in response to resistance exercise, administration of essential amino acids only following exercise has the same positive anabolic effect on muscle as complete amino acid supplementation. Furthermore, oral administration of whole proteins following training has a similar anabolic effect, as whole proteins such as whey and casein ...

Sarcopenia is a well-known phenomenon in elderly individuals and resistance exercise together with sufficient amino acid (AA) availability has proved to be a counteractive implement. However, the source of AA and supplement timing require further investigation. The objective was to compare muscle protein synthesis (MPS) to intakes of whey and caseinate after heavy resistance exercise in healthy elderly individuals, and, furthermore, to compare the timing effect of caseinate intake. Twenty-four elderly men and women (mean ± SEM; 68 ± 1 years) were randomized to one of four groups: caseinate intake before exercise (CasPre), caseinate intake immediately after exercise (CasPost), whey intake immediately after exercise (Whey), or intake of a non-caloric control drink (Control). Muscle myofibrillar and collagen fractional synthesis rates (FSR) were measured by a primed continuous infusion of l-[1-13C]leucine using labeled proteins during a 6-h recovery period. No differences were observed in muscle ...
I think its fair to say that there are very few players who are not actively looking to increase their muscle mass or improve their body composition. Research suggests that additional muscle mass can improve the predicted success in some team sports such as rugby1. Building muscle is a multi-faceted approach and the following 3 tips will help you maximise those gains and improve performance.. Tip #1 - Engage in resistance training. Resistance Training (RT) is the single most important factor in building muscle. During RT muscle fibres are broken down and muscle protein synthesis (MPS) is increased. However, although MPS is increased, supporting nutrition in the form of protein is needed in order to ensure MPS is greater than muscle protein breakdown (MPB) and muscle grows. There is no change in muscle growth after one RT session but instead muscle hypertrophy is due to the accumulation of muscle protein in response to each individual bout of RT training plus protein that occurs ...

Background & aim: Protein-energy supplementation is routinely employed to combat muscle loss. However, success is often compromised by increased satiety, poor palatability, high costs and low compliance. Methods: For 2-weeks we supplemented meals of older individuals with leucine (4 g/meal; 3 meals/day; days 2-14). Metabolic studies were performed prior to (Day 1) and following (Day 15) supplementation. Leucine was not provided on metabolic study days. Venous blood and vastus lateralis muscle biopsies were obtained during a primed constant infusion of L-[ring-C-13(6)] phenylalanine. Mixed muscle fractional synthesis rate (FSR), body composition and markers of nutrient signaling (mTOR, 4E-BP1 and p70S6K1 phosphorylation) were measured before and after a low protein/carbohydrate simulated meal. Results: The meal modestly increased FR on Day 1 (postabsorptive: 0.063 +/- 0.004 vs. postprandial: 0.075 +/- 0.006%/h; p = 0.03), however, two weeks of leucine supplementation increased postabsorptive FSR (p = 0

Results: The preexercise rise in plasma AA concentration with PULSE was attenuated compared with BOLUS (P less than 0.05); this effect was reversed after exercise, with two-fold greater leucine concentrations in PULSE compared ...
LEUCINE IS THE TRIGGER!!!. New scientific studies show that Leucine is a powerful nutritional activator of muscle protein synthesis*. It activates the anabolic pathway for building muscle.. These new findings confirm that within the context of a mixed macronutrient intake, suboptimal protein doses can be made more effective in stimulating myofibrillar protein synthesis, through the addition of a high proportion of free Leucine.. This branched chained amino acid is essential for achieving a positive nitrogen balance in building lean muscle mass. Leucine is discribed as the trigger of muscle protein synthesis.. * Muscle protein synthesis (MPS) is the rebuilding of muscle tissue and it occurs as a result of the stresses that we place on our body, whether it is to repair injury (such as a muscle tear) or because we intentionally try to damage it (microtrauma from training).. ...
It turns out that only slight elevations of insulin above basal levels are all thats required to blunt muscle catabolic effects. Just consuming protein alone is enough to elicit a release of insulin that is sufficient to interact with the ingested amino acids in promoting muscle protein synthesis. Leucine alone is known to promote the release of insulin. This explains the recent studies showing that protein alone is enough to boost muscle protein synthesis following training. Indeed, one study showed that boosting insulin levels 30-times above fasting level did not further boost muscle protein synthesis if blood levels of amino acids were high. Just consuming protein alone, especially whey, which is rich in leucine, is enough to boost insulin levels 2-3-fold above resting levels. This level of insulin alone is enough to provide the anti-catabolic effects of insulin following exercise. Other studies show that adding 30 or 90 grams of carbs to 20 grams of protein does not boost muscle protein ...

Muscle bulk and strength naturally decline with age, as the tissues regenerate more slowly. Without efforts to stay strong and healthy, this can accelerate into sarcopenia, a prevalent, muscle wasting condition with multiple dire health outcomes.. Poor wound healing, increased risk of falls, hospitalisation, loss of independence and mortality are just some of the ripple effects caused by declining muscle mass.. Its well known that protein is important for helping to maintain muscle mass, with evidence that older adults benefit from 1g protein per kilogram of body weight per day - which is higher than current recommendations of 0.8g/kg body weight.. Some researchers say the focus should be on consuming 25-30g protein per meal for optimum muscle protein synthesis.. In older adults, however, muscle protein synthesis is less efficient if protein and carbohydrates are eaten together. The researchers suggest this could be improved by supplementing mixed-nutrient meals with leucine.. The importance of ...
Resistance coaching and subsequent intake of a protein-rich food encourages muscle mass hypertrophy and gains in muscle mass toughness by stimulating myofibrillar muscle protein synthesis (MPS) and inhibiting muscle protein breakdown (MPB).[108][109] The stimulation of muscle mass protein synthesis by resistance education happens by means of phosphorylation in the mechanistic target of rapamycin (mTOR) and subsequent activation of mTORC1, which ends up in protein biosynthesis while in the ribosome by means of phosphorylation of mTORC1s speedy targets (the p70S6 kinase and the translation repressor protein 4EBP1 ...

Actual physical performance will depend on numerous muscle mass functions, including toughness. Muscle mass protein synthesis and breakdown are central in determining the two power and General operate. Even so, most research in the area of muscle operate and physical exercise has focused on energy metabolism in lieu of the regulation of muscle mass protein metabolism. Essential thoughts continue to be unanswered regarding the mechanisms governing the response of muscle protein synthesis and breakdown to training, and the result of exercising on protein specifications in individuals continues to be controversial. Methodologic troubles have confined the exploration of these along with other troubles about muscle mass protein kinetics due to best whey protein at amazing prices problem of quantifying muscle mass protein synthesis and breakdown in people. In lieu of direct measurement of protein kinetics, the result of protein ingestion on effectiveness variables including energy continues to be ...

So, it would make sense that eating barbaric amounts of protein will lead to colossal gains, right? Well, not really. Countless studies have shown that the law of diminishing returns applies to protein intake and muscle building. Researchers at the University of Stirling have discovered that muscle protein synthesis is maximally stimulated when 20 - 40g of a highly bioavailable protein source such as whey or meat is consumed after training (this range is dependent on the amount of lean body mass that is stimulated by resistance exercise). The remainder of the protein consumed was either used in non-muscle tissue protein synthesis or processed by the liver to make glucose or fatty acids - not to generate more skeletal muscle. Research has confirmed that to build muscle mass, a minimum of 1.6g/kg/d is required in healthy non-dieting adults. Protein intake above this, may be used for different purposes.. ...
1. Quadriceps muscle protein turnover was assessed in the post-absorptive state in six men immediately after the end of unilateral leg immobilization (37 ± 4 days) in a plaster cast after tibial fracture. A primed-constant intravenous infusion of l-[1-13C]leucine was administered over 7 h. Quadriceps needle biopsies, taken bilaterally at the end of the infusion, were analysed for muscle protein leucine enrichment with 13C.. 2. Quadriceps muscle protein synthetic rate, calculated from the fractional incorporation of [13C]leucine into protein compared with the average enrichment of blood α-ketoisocaproate, was 0.046 ±0.012%/h in the uninjured leg, but was only 0.034 ±0.007%/h in the quadriceps of the previously fractured leg (P , 0.05, means ± sd).. 3. Muscle RNA activity (i.e. protein synthetic rate per RNA) fell from 0.27 ±0.08 μg of protein synthesized h−1 μg−1 of RNA in the control leg to 0.14 ±0.03 μg of protein synthesized h−1 μg−1 of RNA in the immobilized leg (P , ...

Strenuous exercise following overnight fasting increases fat oxidation during exercise, which can modulate training adaptation. However, such exercise induces muscle protein catabolism by decreasing blood insulin concentrations and increasing amino acid oxidation during the exercise. Leucine-enriched essential amino acids (LEAAs) enhance muscle protein synthesis (MPS) at rest and after exercise. However, it remains to be clarified if the co-ingestion of carbohydrate with LEAAs induces an additional increase in MPS, particularly in a hypoinsulinemic state induced by strenuous exercise. Eight-week-old male Sprague-Dawley rats were made to perform strenuous jump exercise (height 35 cm, 200 jumps, 3-s intervals), after which they ingested distilled water and 1 g/kg LEAAs with or without 1 g/kg of glucose. The fractional synthesis rate was determined by measuring the incorporation of l-[ring-2H5]-phenylalanine into skeletal muscle protein. Immediately after the exercise, plasma insulin concentration was

Due to insufficient exercise training, skeletal mucle loss is beginning form 25 years old. Sarcopenia is the critical reason to effect activities of daily life in seniors. Strength training has been proven to be a great strategy to increase mucle mass and functions. Exercise training provokes skeletal muscle protein synthesis, in the meantime also causes muscle injury, induces muscle protien degradation and muscle cell inflammatory. Net muscle protein balace will become negative in nutrients or rest deficiency. Muscle biogenesis decreasing with aging may induce by signal transmit weakening in muscle protein synthesis pathway. Current studies showed that the phosphatidylinositol 3-kinase /AKT/mammalian target of rapamycin (PI3K/Akt/ mTOR) pathway is an important pathway to regulate skeletal muscle hypertrophy. Therefore, the first year, resveratrol is uesd as a nutriental ergogenic aid which may activate related protein expression of muscle synthesis pathway. In order to understand promotion or ...

Rationale: The giant protein titin plays key roles in myofilament assembly and determines the passive mechanical properties of the sarcomere. The cardiac titin molecule has 2 mayor elastic elements, the N2B and the PEVK region. Both have been suggested to determine the elastic properties of the heart with loss of function data only available for the N2B region.. Objective: The purpose of this study was to investigate the contribution of titins proline-glutamate-valine-lysine (PEVK) region to biomechanics and growth of the heart.. Methods and Results: We removed a portion of the PEVK segment (exons 219 to 225; 282 aa) that corresponds to the PEVK element of N2B titin, the main cardiac titin isoform. Adult homozygous PEVK knockout (KO) mice developed diastolic dysfunction, as determined by pressure-volume loops, echocardiography, isolated heart experiments, and muscle mechanics. Immunoelectron microscopy revealed increased strain of the N2B element, a spring region retained in the PEVK-KO. ...
1. We have used l-[1-13C,15N]leucine as the substrate tracer to study leucine and muscle protein metabolism across the forearm of eight normal fasting adults.. 2. The rates of protein synthesis and breakdown, de- and re-amination of leucine, and the oxidative de-carboxylation of its keto acid were calculated directly from the arteriovenous metabolite balances and isotope dilutions as described by the metabolic model.. 3. The results were compared with those obtained previously when subjects were fed. The effects of fasting on protein and leucine metabolism were a significant decrease in protein synthesis from 127 (sem 11; n = 6) to 70 (sem 6; n = 12) nmol of leucine min−-1 100 ml−-1 of forearm tissue (P , 0.001) and a marked decrease in leucine catabolism in the forearm muscle.. 4. This model has demonstrated that each subject was in negative protein balance across the forearm during fasting while positive during feeding, the mean values being −29(sem 5; n = 12) and + 39(sem 9; n = 6) nmol ...
The peroxisome proliferator-activated receptor γ (PPARγ) agonist rosiglitazone (Rosi) appears to provide protection against organ dysfunction during endotoxaemia. We examined the potential benefits of Rosi on skeletal muscle protein maintenance and carbohydrate metabolism during lipopolysaccharide (LPS)-induced endotoxaemia. Sprague-Dawley rats were fed either standard chow (control) or standard chow containing Rosi (8.5±0.1 for two weeks before and during 24 h continuous intravenous infusion of LPS (15 μ or saline. Rosi blunted LPS-induced increases in muscle tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) mRNA by 70% (P,0.05) and 64% (P,0.01), respectively. Furthermore, Rosi suppressed the LPS-induced reduction in phosphorylated AKT and phosphorylated Forkhead box O (FOXO) 1 protein, as well as the upregulation of muscle RING finger 1 (MuRF1; P,0.01) mRNA, and the LPS-induced increase in 20S proteasome activity (P,0.05). Accordingly, LPS reduced the ...

The active and passive contractile performance of skeletal muscle fibers largely depends on the myosin heavy chain (MHC) isoform and the stiffness of the titin spring, respectively. Open questions concern the relationship between titin-based stiffness and active contractile parameters, and titins importance for total passive muscle stiffness. Here, a large set of adult rabbit muscles (n = 37) was studied for titin size diversity, passive mechanical properties, and possible correlations with the fiber/MHC composition. Titin isoform analyses showed sizes between ∼3300 and 3700 kD; 31 muscles contained a single isoform, six muscles coexpressed two isoforms, including the psoas, where individual fibers expressed similar isoform ratios of 30:70 (3.4:3.3 MD). Gel electrophoresis and Western blotting of two other giant muscle proteins, nebulin and obscurin, demonstrated muscle type-dependent size differences of ≤70 kD. Single fiber and single myofibril mechanics performed on a subset of muscles ...
Insulin stimulates muscle protein synthesis when the levels of total amino acids, or at least the essential amino acids, are at or above their postabsorptive concentrations. Among the essential amino acids, branched-chain amino acids (BCAA) have the primarily role in stimulating muscle protein synthesis, and are commonly sought alone to stimulate muscle protein synthesis in humans. Fourteen healthy, young subjects were studied before and after insulin infusion to examine whether insulin stimulates muscle protein synthesis in relation to the availability of BCAA alone. Half of the subjects were studied in the presence of postabsorptive BCAA concentrations (Control), while the other half in the presence of increased plasma BCAA (BCAA). When compared to that prior to the initiation of the insulin infusion, fractional synthesis rate of muscle protein (%/hour) did not change (P , 0 .05) during insulin in either the Control (0.04 ± 0.01 vs 0.05 ± 0.01) or the BCAA (0.05 ± 0.02 vs 0.05 ± 0.01) ...
If youre a serious student of muscle, you may have heard of the mTOR pathway. Well, mTORC1 includes not only mTOR, but also several additional processes that stimulate muscle protein synthesis.. The mTORC1 pathway controls the anabolic and catabolic signaling of skeletal muscle mass, regulating muscle growth and muscle breakdown. And research has shown that supplementing essential amino acids in conjunction with resistance training has an additive effect on stimulating muscle protein synthesis through this pathway compared to just resistance training.. The translation for you: Essential amino acids can help maximize the hard work we put in at the gym to stimulate muscle protein synthesis. If youre stimulating muscle protein synthesis you put yourself in a favorable position to gain muscle or at least not break down your existing muscle..

The use of ambient desorption electrospray ionization (DESI-MS) mass spectrometry and liquid extraction surface analysis mass spectrometry (LESA-MS) is explored for the first time to analyse skeletal muscle proteins obtained from mixture of standard proteins and raw meat. Single proteins and mixtures of up to five proteins (myoglobin, troponin C, actin, BSA, tropomyosin) were deposited onto a polymer surface, followed by in-situ tryptic digestion and comparative analysis using DESI-MS and LESA-MS using tandem electrospray MS. Peptide peaks specific to individual proteins were readily distinguishable with good signal-to-noise ratio in the five-component mixture. LESA-MS gave a more stable analysis and greater sensitivity compared with DESI-MS. Meat tryptic digests were subjected to peptidomics analysis by DESI-MS and LESA-MS. Bovine, horse, pig, chicken and turkey muscle digests were clearly discriminated using multivariate data analysis (MVA) of the peptidomic datasets. The most abundant ...

Advancing age is associated with a reduction in skeletal muscle protein, muscle strength, muscle quality, and chemical modifications that may impair protein function. Sarcopenia has been coupled with physical disability, frailty, and a loss of independent function (5, 19). Using stable isotope tracer methodologies and mass spectrometric detection, we observed: (a) 76-92-year-old physically frail and 62-74-year-old middle-age adults have lower mixed muscle protein synthetic rates than 20-32-year-old men and women; (b) 2 weeks and 3 months of weightlifting exercise increased the synthetic rate of myosin heavy chain (MHC) and mixed muscle proteins to a similar magnitude in frail, middle-age, and young women and men; (c) Serum myostatin-immunoreactive protein levels were elevated in physically frail women and were inversely correlated with lean mass. This suggests that the protein synthetic machinery adapts rapidly to increased contractile activity and that the adaptive response(s) are maintained ...

NutraBio HMB is a clinically proven ergogenic aid that has been shown in over 50 human studies to improve strength and power gains, increase lean mass, and aid recovery. HMB (short for beta-hydroxy beta-methylbutyrate) in an active metabolite of leucine that has both anticatabolic and anabolic properties. Due to these attributes HMB reduces muscle protein breakdown while also inducing muscle protein synthesis. This means HMB can lead to rapid strength gains in less time, significantly increase lean muscle mass, support more complete muscle recovery, and reduce muscle damage from resistance exercise. In fact, a recent position stand by the International Society of Sports Nutrition validates these claims. Based upon the comprehensive review of the HMB literature they concluded that HMB enhances muscle recovery by attenuating muscle damage; HMB increases muscle hypertrophy, strength, and power in trained and untrained populations when the appropriate exercise protocol is applied; HMB efficacy is ...
To find the optimal level of protein intake at a meal we must determine what the optimal level of protein at a meal for stimulating muscle protein synthesis is. It appears that maximizing skeletal muscle protein synthesis requires approximately ~15g of essential amino acids. It has been postulated that the amino acid leucine is responsible for the stimulatory effect of dietary protein on protein synthesis and 15g of essential amino acids would contain 3.2g of leucine. Thus, in order to determine how much protein from a specific source is required to elicit the maximal response it may be useful to also calculate how much leucine is contained in the source. One could then determine how much of the source must be consumed in order to reach the leucine threshold. For example, whey protein is approximately 12% leucine; therefore, about 27g of whey protein would need to be consumed to reach the threshold for maximal anabolism, whereas a source like chicken, which has a protein content of about 7.5% ...
We determined myofibrillar and mitochondrial protein fractional synthesis rates (FSR), intramuscular signaling protein phosphorylation, and mRNA expression responses after isolated bouts of resistance exercise (RE), aerobic exercise (AE), or in combination [termed concurrent exercise (CE)] in sedentary middle-aged men. Eight subjects (age = 53.3 ± 1.8 yr; body mass index = 29.4 ± 1.4 kg·m2) randomly completed 8 × 8 leg extension repetitions at 70% of one repetition-maximum, 40 min of cycling at 55% peak aerobic power output (AE), or (consecutively) 50% of the RE and AE trials (CE). Biopsies were obtained (during a primed, constant infusion of l-[ring-13C6]phenylalanine) while fasted, and at 1 and 4 h following postexercise ingestion of 20 g of protein. All trials increased mitochondrial FSR above fasted rates (RE = 1.3-fold; AE = 1.5; CE = 1.4; P , 0.05), although only CE (2.2) and RE (1.8) increased myofibrillar FSR (P , 0.05). At 1 h postexercise, phosphorylation of Akt on Ser473 (CE = ...

In this study, we aimed to further dissect the molecular components required for the coordinated organization of Z-line components into regular, hexagonal lattices. We took the approach of searching for protein interactions that anchor the COOH-terminal region of nebulin within the sarcomere. This allowed us to identify the specific binding of the nebulin modules M160-M183, from the peripheral (I-band side) region of the Z-line (Millevoi et al. 1998), with the intermediate filament protein, desmin. Studies are currently under investigation to determine whether desmin and nebulin indeed participate in a coordinated cytoskeletal network that could provide lateral linkages in the Z-line perimyofibrillar space, allowing for efficient force transmission and mechanochemical signaling.. This study has also led to the identification of a novel nebulin-binding protein, myopalladin, which we named based on its striking homology with the recently described ubiquitously expressed protein, palladin (Parast ...
TY - JOUR. T1 - Cardiac titin. T2 - A multifunctional giant. AU - Lewinter, Martin M.. AU - Granzier, Hendrikus Henk. PY - 2010/5/18. Y1 - 2010/5/18. N2 - Titin is responsible for the passive and restoring force of the cardiac sarcomere and makes a major contribution to the diastolic wall stress of the LV, the level of which can be tuned through differential splicing and phosphorylation. PKA and PKG phosphorylation lower stress, and PKC increases it. Changes in titin phosphorylation and titin splicing occur in cardiac disease, in addition to mutations in the titin gene. A host of titin-binding proteins have been discovered that implicate titin as a key player in the organization and development of the sarcomere, in protein turnover, and in sensing mechanical stress. Several stress-sensing signalosomes along the molecule have been discovered, of which only the FHL-based signalosome binds to a spring element (N2B).

BCAAs have been proposed to benefit performance in several ways including as a stimulant for muscle protein synthesis (through leucine). BCAAs may also prevent muscle protein breakdown and reduce markers of exercise induced muscle damage. There is also some research suggesting that BCCAs have the potential to act as a fuel source for muscles during exercise, although the research surrounding this is inconclusive. Lastly, BCAAs may interfere with the transport of tryptophan into the brain, reducing the synthesis of serotonin thereby reducing feelings of fatigue.. ...
PHILADELPHIA - Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called leiomodin (Lmod) promotes the assembly of an important heart muscle protein called actin. Whats more, Lmod directs the assembly of actin to form the pumping unit of the heart. The findings appear in this weeks issue of Science.. Very little was known about Lmod when we began this study, says lead author Roberto Dominguez, PhD, Associate Professor of Physiology. It appeared that this protein was present in muscle cells but this had not been demonstrated directly and nobody knew what it did, explains Dominguez. We compared the amino acid sequence of Lmod with the sequence of another protein called tropomodulin [Tmod] that was already known to bind actin filaments in muscle cells. We found that one part of Lmod was very similar to Tmod, but Lmod was a bigger protein than Tmod and contained unique features that made us suspect that it could assemble the actin filaments of the ...

Unfortunately, this study leaves us with way more questions than answers. I personally, for example would venture the guess that the ingestion of a complete EAA product would result in an even more profound amelioration of the fasting induced reduction in fractional protein synthesis. That being said, the latter could also compromise another advantage of the non-essential amino acids, I have not even mentioned, yet: their almost non-existent effect on intra-muscular AMPK-expression (cf. figure 2, right). If you read all Intermittent Thoughts articles which dealt with the AMPK/mTOR Metabolic Seesaw and the respective follow-ups, you will be familiar with notion that the fasting-induced phosphorylation of intra-muscular AMPK is responsible for the majority of the health, as well as the closely related fat-burning effects of (intermittent) fasting. Now, if the ingestion of a ~20g bolus of alanine, glycine, proline, histidine, asparagine and serine could increase your skeletal muscle protein ...

  • Muscle proteins are in a dynamic equilibrium between their respective rates of synthesis and breakdown. (
  • It has been suggested that age-related sarcopenia is due to: i) elevated basal-fasted rates of muscle protein breakdown, ii) a reduction in basal muscle protein synthesis (MPS), or iii) a combination of the two factors. (
  • However, basal rates of muscle protein synthesis and breakdown are unchanged with advancing healthy age. (
  • Ageing muscle is less sensitive to lower doses of amino acids than the young and may require higher quantities of protein to acutely stimulate equivalent muscle protein synthesis above rest and accrue muscle proteins. (
  • Although the etiology of sarcopenia is multifaceted, [ 8 ] in the context of this review we will focus, primarily, on the contribution of alterations in muscle protein turnover (muscle protein synthesis and breakdown) to muscle wasting in the elderly. (
  • Our understanding of the contribution of muscle protein turnover to sarcopenia has shifted from a thesis in which basal muscle protein metabolism was thought to be compromised in the elderly, to a new paradigm whereby the synthetic responsiveness of muscle protein synthesis to anabolic stimuli, such as food and contractile loading, is blunted with aging. (
  • In accordance with the reduced expression of anabolic genes such as Igf1 , surface sensing of translation (SUnSET) analyses of fast-twitch Ga, TA and Sol muscles revealed that the KD suppressed muscle protein synthesis. (
  • Balanced muscle protein synthesis and degradation can retain skeletal muscle mass and muscle performance. (
  • According to a report published in the Journal of the International Society of Sports Nutrition in January 2013, just incorporating resistance training into your exercise routine alone has been shown to double the rate of protein synthesis after exercise. (
  • A combination of amylopectin and chromium may double the muscle protein synthesis rate compared to what was seen when using whey protein alone, says a new study using Nutrition 21's patented Velositol ingredient. (
  • This is especially true of carbs and proteins, which work hand in hand to maximize protein synthesis during and after your workout, resulting in optimized muscle anabolism. (
  • Hydrolysates also enhance protein synthesis when combined with lower doses (less than 15 grams) of other forms of protein. (
  • The effect of TNFBP on gastrocnemius weight, protein content, and the rate of protein synthesis was examined 5 days later. (
  • Sepsis reduced the rate of protein synthesis by 35% relative to controls by depressing translational efficiency. (
  • Decreases in protein synthesis were accompanied by similar reductions in protein content and muscle weight. (
  • Treatment of septic animals with TNFBP for 5 days prevented the sepsis-induced inhibition of protein synthesis and restored translational efficiency to control values. (
  • TNFBP treatment of Control rats for 5 days was without effect on muscle protein content or protein synthesis. (
  • The data suggest that TNF may impair muscle protein synthesis by reducing expression of specific initiation factors during sepsis. (
  • Elliott TA, Cree MG, Sanford AP, Wolfe RR & Tipton K (2006) Milk ingestion stimulates net muscle protein synthesis following resistance exercise. (
  • Net muscle protein synthesis results from the combination of resistance exercise and amino acid intake. (
  • CONCLUSIONS: Ingestion of milk following resistance exercise results in phenylalanine and threonine uptake, representative of net muscle protein synthesis. (
  • These results suggest that whole milk may have increased utilization of available amino acids for protein synthesis. (
  • The research was revived when scientists moved away from androgenic receptors, and looked at protein synthesis rates. (
  • They found protein synthesis rates increased in animal muscle tissue . (
  • Healthy fats known as omega-3 fatty acids found in salmon and tuna help boost the synthesis of muscle proteins and increase the size of muscle cells. (
  • The three BCAAs have been touted to increase muscle protein synthesis, reduce breakdown, facilitate repair and recovery from exercise, as well as reducing feelings of exertion and fatigue during exercise. (
  • Rates of myofibrillar protein synthesis from resting/ basal fractional synthetic rate to the end of post-experimental period as measured by deuterium oxide (D2O) uptake into skeletal muscle and calculated by using mass isotopomer distribution analysis based on previous work (PMID: 28855275). (
  • How long would it take to burn off 100 Calories of Muscle Milk Light Chocolate Lean Muscle Protein Powder Drink Mix? (
  • Today, there are plenty of different kinds of protein powder on the market sourced from both plants and animals. (
  • That being said, it's generally thought to be the case, and you can usually be assured that the protein powder comes from a byproduct of cows that feed on grass, shrubs, leaves, and bushes instead of grains or any other form of food. (
  • This results in a protein powder that's less caloric and better suitable for those with lactose sensitivities, but it's often more expensive to produce and this purchase. (
  • It's important when choosing a whey protein powder to stay away from added sugars, artificial sweeteners, artificial flavors, and unnecessary thickening agents. (
  • Milk protein isolate powder is one of your best choices for muscle building and anabolic conditioning, it may be better than just using whey protein or casein protein alone. (
  • Milk protein isolate powder that is commercially sold comprises of 80% casein and 20% whey. (
  • Is a blend of casein and whey better for muscle growth than whey protein isolate or micellar casein protein powder alone? (
  • Is it better to buy your protein powders separately and get yourself some whey protein isolate or whey protein concentrate, micellar casein, hydrolyzed protein powder , and other proteins and then mix them together OR should you just go out and buy milk protein isolate powder ? (
  • Do we simply use a 50/50 mix or do we do with a milk protein isolate powder? (
  • Not very good choice to use for a protein powder. (
  • Micellar casein protein powder is made using microfiltration which of course if the better version. (
  • Our blended Promax Lean powder is a fat free, sugar free, high protein shake designed to support lean muscle development. (
  • Mixing this lean definition protein powder is easily mixed. (
  • But does protein (powder) ice cream really have the taste and texture of real ice cream? (
  • Understanding that casein is a thicker protein powder, I first started making it exclusively with casein. (
  • I didn't find it was even necessary when using casein protein powder. (
  • If you try a vegan protein powder that is not casein, please post in the comments and let me know. (
  • The ability for hydrolyzed protein powder to be easily digested and absorbed at a quick rate is what sets it apart from other protein powders. (

  • In short, show me a bodybuilder who is engaging in any sort of "fad diet" that shortchanges carbs, proteins or fats, and I'll show you an athlete on the road to ruin. (
  • In fact, much of the bodybuilding community associates "eating clean" with emphasizing proteins over carbs. (
  • Like Dr. Kreider, Anssi Manninen believes that bodybuilders should eat moderate amounts of carbs when trying to maximize muscle gains. (
  • Manninen continues, "Your body needs muscle glycogen (i.e., a storage form of carbs) to fuel that intense workout you have planned at the gym. (
  • Protein calories are not likely to be stored as fat as compared to carbs, because protein requires more energy to metabolize and assimilate and has numerous functions. (
  • Anyone who suffers from an exaggerated desire for carbs probably needs to eat more protein. (
  • However, you don't have any carbs at all yet 22 grams of protein. (
  • When you're looking for a recipe that is full of protein and healthy carbs for a sporting event, this is a great way to go. (
