Question: Is progressive resistance training as effective as aerobic training of similar duration in sedentary older adults with diabetes mellitus? Design: A randomised trial with concealed allocation, assessor blinding and intention-to-treat analysis. Participants: Sixty people with Type 2 diabetes mellitus with glycosylated haemoglobin (HbA1c) between 8% and 10% in the past month. Intervention: One group undertook progressive resistance exercise and the other group undertook aerobic exercise. Both groups completed 18 sessions over 8 weeks. In each session, the progressive resistance exercise group did nine resistive exercises while the aerobic exercise group did 50 minutes of aerobic exercise. Outcome measures: HbA1c, blood glucose, lipid profile (total, high- and low-density cholesterol and triglycerides), weight, body mass index, body fat, waist circumference, waist:hip ratio, blood pressure, and peak oxygen consumption. Results: Forty-nine (82%) participants completed the intervention. ...

Background: To examine the effects of a community-based resistance training program (Lift for Life (R)) on waist circumference and functional measures in adults with or at risk of developing type 2 diabetes. Methods: Lift for Life is a research-to-practice initiative designed to disseminate an evidence-based resistance training program for adults with or at risk of developing type 2 diabetes to existing health and fitness facilities in the Australian community. A retrospective assessment was undertaken on 86 participants who had accessed the program within 4 active providers in Melbourne, Australia. The primary goal of this longitudinal study was to assess the effectiveness of a community-based resistance training program, thereby precluding a randomized, controlled study design. Waist circumference, lower body (chair sit-to-stand) and upper body (arm curl test) strength, and agility (timed up-and-go) measures were collected at baseline and repeated at 2 months (n = 86) and again at 6 months (n = 32).

TY - JOUR. T1 - Post-exercise blood flow restriction attenuates hyperemia similarly in males and females. AU - Dankel, Scott J. AU - Mouser, J Grant. AU - Jessee, Matthew B. AU - Mattocks, Kevin T. AU - Buckner, Samuel L. AU - Loenneke, Jeremy P. PY - 2017/8. Y1 - 2017/8. N2 - PURPOSE: Our laboratory recently demonstrated that post-exercise blood flow restriction attenuated muscle hypertrophy only in females, which we hypothesized may be due to alterations in post-exercise blood flow. The aim of this study is to test our previous hypothesis that sex differences in blood flow would exist when employing the same protocol.METHODS: Twenty-two untrained individuals (12 females; 10 males) performed two exercise sessions, each involving one set of elbow flexion exercise to volitional failure on the right arm. The experimental condition had blood flow restriction applied for a 3 min post-exercise period, whereas the control condition did not. Blood flow was measured using an ultrasound at the brachial ...

Background: Physical activity is prescribed as a component of primary management for polycystic ovary syndrome (PCOS). This nonrandomized, therapeutic, open, single-arm study investigated the effects of progressive resistance training (PRT) on obesity indices in women with PCOS, and the relationship between obesity indices and telomere content. Methods: A total of 45 women with PCOS and 52 with non-PCOS (controls), aged 18 to 37 years, with body mass indexes of 18 to 39.9 kg/m2, performed three 1-hour sessions of PRT per week, for 16 weeks. Before and after PRT, measures included anthropometric indices and regions of interest of fat mass distribution, quantified by dual-energy X-ray absorptiometry, metabolic and hormonal parameters, and telomere content. The general linear mixed models were used to determine the effects of PRT. Results: PRT did reduce the waist-to-height ratio, waist circumference, and the index of conicity among PCOS (P , .01). However, PRT did not influence regions of ...

This is a randomized, placebo-controlled study to evaluate the effect of creatine monohydrate, a dietary supplement, on skeletal muscle size and function (i.e., strength, energy metabolism, work capacity, fatigue); whole-body exercise performance; and body composition. This study is also designed to determine whether creatine supplementation augments the functional benefit derived from progressive resistance exercise. The safety of creatine supplementation in people with HIV infection will also be evaluated. Forty HIV-positive subjects will be randomly assigned, on a 1:1 basis, to receive creatine monohydrate or placebo for a period of 14 days, followed by a 12-week program of supervised progressive resistance exercise training during which administration of creatine monohydrate or placebo will continue.. Measurements of muscle strength, size, composition, energetics and fatigue, as well as body weight and composition and serum biochemistries, will be made at baseline, after two weeks of ...

W.. PY - 2001. Y1 - 2001. N2 - Objective: To examine the effects of resistance training on hematological and selected indices of iron status in 17 women aged 54-71 years and 18 men aged 56-69 years. Design: Tests and evaluations were done before and after all subjects participated in a resistance training program twice weekly for 12 weeks. Results: The resistance training was effective as evidenced by increases in skeletal muscle strength of 20 ± 9% and 23 ± 13% for the men and women, respectively. Hematological parameters and serum iron concentrations were within normal clinical ranges and were unchanged by resistance training for both the men and the women. Total iron binding capacity (TIBC) and transferrin saturation were also unaffected by resistance training in the women but were ...

Physical fitness has an inverse correlation with systemic inflammation. This essence show that anti inflammatory effects of physical activity my explain some of its beneficial influences on body systems. Then, regarding to the effects of physical training on biochemical and physiological aspects in human, this present study attempted to investigate the effect of resistance training on some of systemic inflammatory markers in overweight men. Accordingly, twenty one healthy overweight (BMI=28.56± 2.67) yang (22.31±2.42) students were volunteered to participate and randomly divided into two groups: Resistance training group (n=11) and non-exercising control group (n=10). The training group performed a progressive 8-week resistance training 3session/wk at about 50 to 80 % of one repeated maximum (1RM). Prior to and after the training program, a blood sample was collected from the subjects in order to measure Interlukine-1 beta (IL-1ȕ) and C reactive protein (CRP). Results of two-way ANOVA for repeated

This study has demonstrated that a supervised progressive high-intensity resistance training program performed 3 days/week for 6 months was safe and well tolerated by older patients with type 2 diabetes and was effective in improving glycemic control and muscle strength. The combination of resistance training and moderate weight loss was associated with a threefold greater decrease in HbA1c levels after 6 months compared with moderate weight loss without resistance exercise, and this was not mediated by concomitant reductions in body weight, waist circumference, and fat mass. The addition of resistance training also contributed to the maintenance of LBM despite moderate weight loss.. Traditionally, aerobic activities have been recommended for people with type 2 diabetes because of the known benefits on insulin sensitivity and glucose tolerance (7). However, for many older patients with type 2 diabetes, the presence of diabetic complications or coexisting conditions, such as obesity, degenerative ...

INTRODUCTION: Severe obesity is associated with sedentary behavior, low fitness, and metabolic dysmetabolism. Exercise can improve strength, fitness, and metabolic health independent of weight loss in obese patients. Progressive Resistance Training (PRT) is particularly beneficial in modifying body composition, developing musculoskeletal strength, and improving metabolic health. To date, there has been no investigation that measures strength, fitness, and physical performance following a PRT exercise protocol in Class III obese candidates undergoing surgical treatment.. METHODS AND PROCEDURES: The study objective is to evaluate the feasibility and efficacy of PRT as a preoperative exercise protocol in patients with Class III obesity. Patients have been recruited from the weight loss surgery clinics at two major academic centers. Participants are men and women aged 18-65 years with a BMI of greater than or equal to 40 kg/m2 who are considering weight loss surgery at BIDMC and Boston University. ...

TY - JOUR. T1 - Blood flow restriction exercise stimulates mTORC1 signaling and muscle protein synthesis in older men. AU - Fry, Christopher. AU - Glynn, Erin L.. AU - Drummond, Micah J.. AU - Timmerman, Kyle L.. AU - Fujita, Satoshi. AU - Abe, Takashi. AU - Dhanani, Shaheen. AU - Volpi, Elena. AU - Rasmussen, Blake. PY - 2010/5. Y1 - 2010/5. N2 - The loss of skeletal muscle mass during aging, sarcopenia, increases the risk for falls and dependence. Resistance exercise (RE) is an effective rehabilitation technique that can improve muscle mass and strength; however, older individuals are resistant to the stimulation of muscle protein, synthesis (MPS) with traditional high-intensity RE. Recently, a novel rehabilitation exercise method, low-intensity RE, combined with blood flow restriction (BFR), has been shown to stimulate mammalian target of rapamycin complex 1 (mTORC1) signaling and MPS in young men. We hypothesized that low-intensity RE with BFR would be able to activate mTORC1 signaling and ...

The age-related decline in functional capability is preceded by a reduction in muscle quality. The purpose of this study was to assess the combined effects of progressive resistance training (PRT) and protein supplementation beyond habitual intakes on upper leg lean tissue mass (LTM), muscle quality and functional capability in healthy 50-70 years women. In a single-blinded, randomized, controlled design, 57 healthy older women (age 61.1 ± 5.1 years, 1.61 ± 0.65 m, 65.3 ± 15.3 kg) consumed 0.33 g/kg body mass of a milk-based protein matrix (PRO) for 12 weeks. Of the 57 women, 29 also engaged in a PRT intervention (PRO + PRT). In comparison to the PRO group (n = 28), those in the PRO + PRT group had an increase in upper leg LTM [0.04 (95% CI -0.07 to 0.01) kg vs. 0.13 (95% CI 0.08-0.18) kg, P = 0.027], as measured by Dual-energy X-ray absorptiometry; an increase in knee extensor (KE) torque [-1.6 (95% CI -7.3 to 4.4 N m) vs. 10.2 (95% CI 4.3-15.8 N m), P = 0.007], as measured from a maximal ...

We examined the effects of progressive resistance training (PRT) and supplementation with calcium-vitamin D3 fortified milk on markers of systemic inflammation, and the relationship between inflammation and changes in muscle mass, size and strength. Healthy men aged 50-79 years (n = 180) participated in this 18-month randomized controlled trial that comprised a factorial 2 × 2 design. Participants were randomized to (1) PRT + fortified milk supplement, (2) PRT, (3) fortified milk supplement, or (4) a control group. Participants assigned to PRT trained 3 days per week, while those in the supplement groups consumed 400 ml day−1 of milk containing 1,000 mg calcium plus 800 IU vitamin D3. We collected venous blood samples at baseline, 12 and 18 months to measure the serum concentrations of IL-6, TNF-α and hs-CRP. There were no exercise × supplement interactions, but serum IL-6 was 29% lower (95% CI, −62, 0) in the PRT group compared with the control group after 12 months. Conversely, IL-6 was 31%

OBJECTIVE: To test the effects of a high intensity home-based progressive strength training program on the clinical signs and symptoms of osteoarthritis (OA) of the knee. METHODS: Forty-six community dwelling patients, aged 55 years or older with knee pain and radiographic evidence of knee OA, were randomized to a 4 month home based progressive strength training program or a nutrition education program (attention control). Thirty-eight patients completed the trial with an adherence of 84% to the intervention and 65% to the attention control. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index pain and physical function subscales. Secondary outcomes included clinical knee examination, muscle strength, physical performance measures, and questionnaires to measure quality of life variables. RESULTS: Patients in the strength training group who completed the trial had a 71% improvement in knee extension strength in the leg reported as most painful versus ...

Frailty is a clinical entity associated with an increase in risk for disease and death and becomes more common as people age. Frailty has a strong relationship with the age-related loss of muscle and strength, termed sarcopenia. Sarcopenia and frailty are strongly associated with disability, especially in women. Adequate protein intake, the amino acid leucine, and resistance exercise training have been individually shown to increase muscle mass to varying degrees. However, no studies have investigated how a longer-term resistance exercise training program with leucine supplementation when protein intake is optimized could increase muscle mass in frail and pre-frail elderly women. In addition, this is the population that stands the most to gain from such an intervention.. The purpose of this study is to investigate the effects of the amino acid leucine added to resistance exercise training on muscle mass and physical performance in frail and pre-frail elderly women with adequate protein intake. ...

This study was designed to determine whether there was a cumulative effect on several days of acute resistance exercise performed in one week on glucose and insulin responses during an oral glucose tolerance test (OGTT) in 14 healthy older adults. Participants performed three sets of 10 repetitions at 75% of the 3RM maximum on eight resistance exercises on three nonconsecutive days in 1 week. Insulin and glucose responses to an OGTT were measured at baseline, 24 hours after 1 and 3 days of exercise, and 72 hours after the third bout of exercise. The 3 days of acute exercise had nosignificant effects on fasting glucose or insulin responses. There also were no significant differences in glucose or insulin responses during any of the OGTTs following the exercise sessions. In conclusion, three bouts of acute resistance exercise performed on nonconsecutive days in 1 week does not have a cumulative effect on insulin or glucose responses to a glucose challenge. These findings suggest that a greater ...

Exercise therapy is a core component of rehabilitation after burn injury, however, there are limitations to our knowledge of best practice. Resistance training (RT) may have some benefit for improving muscle strength after burn injury, though the quality of evidence for this is low.. To determine if a high load RT program is feasible and whether the addition of early RT to routine physiotherapy improves muscle strength and self-report physical function after burn injury.. Allocation to a resistance training group (RTG) or control group (CG) was randomised. The RTG performed a 4-week RT program commencing within 72 hours of injury in addition to usual rehabilitation. Maximal isometric muscle strength and self-report functional surveys for upper and lower limb were assessed at 6 weeks, 3 months and 6 months after enrolment. Muscle strength results were analysed using a mixed effects linear regression and negative binomial regression was used for physical function. Adjustment for covariables and ...

Changes in blood pressure (BP) may affect pain. However, the interaction effect of resistance training and green tea on BP and pain has not been studied. The primary aim of this study was to evaluate the impact of resistance training and green tea extract (GTE) on pain variables in hypertensive patients. Secondary aim included determining the effects of BP alterations on pain responses. In a randomized, double-blind, placebo-controlled study, 30 middle-aged sedentary women were randomly divided into resistance training and green tea extract (GR, n = 8), resistance training (R, n = 8), green tea (G, n = 7), and control groups (C, n = 7). The study period consisted of 3 weeks of GTE (~ 245 mg total polyphenols) consumption twice a day followed by 6 weeks of interaction with resistance training. GR and R groups performed two circuits of training with ten repetitions at 50% of 1RM 2 days a week while other two groups had no any regular exercise training. R and C groups also received placebo capsules

The American College of Sports Medicine (ACSM) guidelines state that during resistance training clients must use a weight of at least 70% of their 1 repetition maximum (RM) to improve strength and hypertrophy. However, for our injured and recovering populations this may not be an option.. Blood Flow Restriction (BFR) rehabilitation can induce a similar strength and hypertrophy response in individuals by exercising at 20% of their 1 Repetition Maximum. Research shows that the increase in metabolic by-products from anaerobic metabolism seems to play as powerful a role in muscle physiology as the mechanical load itself.. We have found this method of rehabilitation to be beneficial in maintaining strength and muscle size post injury with low-level exercise and to build sufficient strength without having to heavily load the injured muscles and/or joints. It has been an adjunct to transition clients and bridge the gap between rehabilitation and performance.. ...

Resistance exercise training can elicit metabolic benefits like improved insulin sensitivity with low to moderate intensity, low volume programs. This is key to engaging sedentary individuals who might be reluctant to participate in strenuous activity. These benefits begin to manifest themselves in a short period of time and these quick results can serve as a motivator to continue training. For the elderly, frail or overweight, resistance training programs are excellent as they provide less risk of sustaining injuries. Prior to beginning a resistance exercise program, diabetic patients should undergo a medical evaluation by their health care professional to ensure that they are safe to participate and that the activities in their programs can be performed correctly to maximize benefits and minimize risk of injury.[3]. The American College of Sports Medicine recommends that resistance training should be integrated into the exercise programs for adults with Type II Diabetes and the following ...

This study was undertaken to determine whether concentric or eccentric muscle action was more likely to induce muscle hypertrophy when exposed to a prolonged heavy resistance exercise program. Fifteen males and 14 females who were not currently or recently involved in a heavy resistance training program for the lower extremities were selected for the study. One group (n = 10) exercised in a concentric fashion, another group (n = 9) exercised in an eccentric fashion, and a third group (n = 10) served as a control group, performing no resistive exercise. The exercising subjects performed three sets of 10 repetitions of resistive knee flexion and extension exercise at 60 degrees/sec, three times per week for 15 weeks at 80% to 100% of their maximal concentric work output on an isokinetic exercise device. Subjects were allowed to increase their intensity of effort as the program progressed to provide continual overload to the exercising muscles to encourage maximal hypertrophy. Isokinetic testing was

PURPOSE: The effects of resistance training on mitochondrial biogenesis and oxidative capacity in skeletal muscle are not fully characterized, and even less is known about alterations in adipose tissue. We aimed to investigate adaptations in oxidative metabolism in skeletal muscle and adipose tissue after 8 weeks of heavy resistance training in apparently healthy young men.. METHODS: Expression of genes linked to oxidative metabolism in the skeletal muscle and adipose tissue was assessed before and after the training program. Body composition, peak oxygen uptake (VO2 peak), fat oxidation, activity of mitochondrial enzyme in muscle, and serum adiponectin levels were also determined before and after resistance training.. RESULTS: In muscle, the expression of the genes AdipoR1 and COX4 increased after resistance training (9 and 13 %, respectively), whereas the expression levels of the genes PGC-1α, SIRT1, TFAM, CPT1b, and FNDC5 did not change. In adipose tissue, the expression of the genes SIRT1 ...

Effect of High-Intensity Resistance Exercise on Elderly Bones Vincent, K.R., & Braith, R.W. Resistance exercise and bone turnover in elderly men and women. Medicine & Science in Sports & Exercise, 34 (1), 17-23.

Background: During aging, a significant loss of muscle mass, strength, and power is associated with a decline in daily functional capacities. Traditionally, resistance training is prescribed to prevent or reverse the skeletal muscle weakness, but the required training intensity may be too demanding for older people with poor physical performance. Resistance exercise with blood flow moderation (KAATSU training), originally developed in Japan, combines resistance exercise with blood flow restriction. It has been reported that KAATSU training enhances muscle hypertrophy in many populations. However, few studies have evaluated the effects of resistance exercises with blood flow restriction in elderly people and how this affects vascular structure and function. Objective: The aim of this study was to evaluate (1) the acute and chronic effects of resistance exercise with blood flow restriction on vascular health in elderly people with low gait speed and (2) whether low-load resistance training with ...

Y1 - 2016. N2 - Breakdown (BD) training has been advocated by multiple commercial and academic publications and authors, seemingly as a result of the acute hormonal and muscle activation responses it produces. However, there is a relative dearth of research that has empirically considered this advanced method of resistance training (RT) over a chronic intervention while appropriately controlling other RT variables. The present study considered 36 male and female participants divided into 3 groups: BD (n = 11), heavy-load breakdown (n = 14), and traditional (n = 11), performing full-body RT programs 2 times per week for 12 weeks. No significant between-group differences were identified for change in absolute muscular endurance for chest press, leg press, or pull-down exercises or for body composition ...

We examined the effects of an 8 w circuit resistance training (RES) program using elastic bands and body weight on TCD4+ cell counts and anthropometry in HIV patients. Patients (N=21) receiving antiretroviral therapy were randomly assigned to resistance training (RES; n=14) or control group (CON; n=7) groups. RES (3/w) consisted of training with elastic bands and bodyweight training focusing on major muscle groups. CON received standard care. Statistical analyses were performed using general linear models adjusted for age, gender, length of infection and respective baseline measures. The primary outcome was TDC4+ and secondary outcomes were anthropometry indices. Tertiary assessments explored Pearson correlations surrounding the relationship between changes in anthropometry and TDC4+. We observed significant increases in TCD4+ count accompanying RES training (105.50 cells/mm3, 95% CI, 47.42, 163.59), while CON significantly decreased (-41.01 cells/mm3, 95% CI, -126.78, 44.76). Significant ...

Authors of a small-scale study are asserting that resistance training may increase testosterone levels in older men. Researchers believe that increased levels of the hormone may help guard against osteoporosis and increase resistance to injury from falls.. The study (abstract only available for free) is published online in the FASEB Journal from the Federation of American Societies for Experimental Biology and documents a research project that involved 6 young men and 13 older men. Levels of testosterone were measured before and after a 12-week resistance training program focused on knee extension and flexion. Biopsies were taken from the vastus lateralis. Researchers found that muscular sex steroid hormone levels and sex steroidgenesis-related enzyme expressions were significantly lower in older subjects than younger ones at baseline, but 12 weeks of resistance training significantly restored hormone levels. Additionally, authors reported significant restoration of steroidogenesis-related ...

The aim of this study was to investigate the effects of a resistance training program with excessive training load and insufficient recovery time between bouts on muscle hypertrophy- and atrophy-related protein expression. Male Wistar rats were randomly assigned to either a trained (TR, N = 9) or a sedentary (SE, N = 9) group. The TR group was subjected to a 12-week resistance training program with excessive training load and insufficient recovery between bouts that was designed to induce plantaris muscle atrophy. After the 12-week experiment, the plantaris muscle was collected to analyze the cross-sectional area (CSA) of the muscle fibers, and MAFbx, MyoD, myogenin, and IGF-I protein expression (Western blot). The CSA was reduced significantly (-17%, p ≤ 0.05) in the TR group compared with the SE group. Reciprocally, there was a significant (p ≤ 0.05) 20% increase in MAFbx protein expression, whereas the MyoD (-27%), myogenin (-29%), and IGF-I (-43%) protein levels decreased significantly ...

by Coach ROBERT HAVILAND MS,BS PT,CSCS,CES. Blood Flow Restriction (BFR) training is an exercise technique that manipulates the bodys circulatory system, and when combined with exercise, produces rapid gains in strength and fitness using light-weights in a very short period of time.. BFR training induces an anabolic response through various pathways perhaps the most important of which is by preferentially targeting the large fast twitch muscle fibers. Fast twitch fibers are the biggest muscle fibers and have the most potential for growth. These fibers are recruited last during contractions and are mostly anaerobic (dont use oxygen) whereas the smaller slow twitch fibers are recruited first during contractions and are aerobic (use oxygen). Slow twitch fibers have a much smaller potential for growth compared to fast twitch fibers. BFR training restricts blood flow to muscles, pre-fatiguing the slow twitch fibers and forcing the anaerobic fast twitch fibers to handle the load even at low ...

There was a time when getting a good pump meant lifting really heavy weights, which are at least 80% of your one-rep-max. That was until blood flow restriction training or BFR training came into the limelight.

Purpose: To assess tissue oxygenation, along with metabolic and physiological responses during blood flow restriction (BFR, bilateral vascular occlusion) and systemic hypoxia conditions during submaximal leg- versus arm-cycling exercise. Methods: In both legs and arms, 4 randomized sessions were performed (normoxia 400 m, fraction of inspired oxygen [FIO2] 20.9% and normobaric hypoxia 3800 m, FIO2 13.1% [0.1%]; combined with BFR at 0% and 45% of resting pulse elimination pressure). During each session, a single 6-minute steady-state submaximal exercise was performed to measure physiological changes and oxygenation (near-infrared spectroscopy) of the muscle tissue in both the vastus lateralis (legs) and biceps brachii (arms). Results: Total hemoglobin concentration ([tHb]) was 65% higher (P , .001) in arms versus legs, suggesting that arms had a greater blood perfusion capacity than legs. Furthermore, there were greater changes in tissue blood volume [tHb] during BFR compared with control ...

What is Blood Flow Restriction (BFR). BFR uses a specialized tourniquet system to limit arterial inflow and occlude venous outflow of an exercising limb. The hypoxic environment created, stimulates strength and hypertrophy gains at a much lighter load.. It is a noninvasive approach for all patients who would be a candidate for surgical procedures involving a tourniquet.. RESULTS WITH BFR. - Diminish atrophy and loss of strength from disuse and non-weight bearing after injuries. - Increase strength with only 30% loads of one rep max. - Gain/Induce hypertrophy with only 30% loads. - Improve muscle endurance in 1/3 the time. - Improve muscle protein synthesis in the elderly. - Improve strength and hypertrophy after surgery - Improve muscle activation - Increase growth hormone secretion. ...

The effect of resistance exercise on TRL-TG metabolism is not known; previous studies only measured total plasma TG concentrations and provide conflicting results. Furthermore, none has specifically examined women. We therefore sought to evaluate the effect of a single bout of resistance exercise on TRL-TG metabolism in women. We measured the concentrations of TG in total plasma and TRLs in the fasting state and during an oral fat ...

Many studies have examined the role of physical activity on changes in body composition. Because of the association between muscle strength, power, and muscle mass and the well described age-related declines in skeletal muscle mass, we examined the literature on the influence of exercise training interventions, in particular resistance training interventions, on changes in muscle and fat-free mass. Studies that were evaluated included trials conducted in young, middle-aged, and older men and women. Very few studies, if any, examined subgroups of different ethnic populations to evaluate variations in responsiveness. The effects of progressive resistance training in young healthy men and women have been well described (151). As reviewed by Kraemer and colleagues, high-intensity progressive resistance training in young adults results in significant increases in dynamic strength, explosive power, and muscle mass. More recent studies have confirmed these findings. Short-term studies of both lower- ...

The effects of time of day-specific resistance training on adaptations in skeletal muscle hypertrophy and muscle strength: A systematic review and meta-analysis:

Systematic, progressive resistance training -- also called strength training -- is a safe and efficient way for middle-aged and older adults to improve their health. A Virginia Tech led research team that includes experts in behavior, exercise, physiology, and medicine is designing a program to help pre-diabetic adults begin and, most important, maintain resistance training in order to prevent diabetes.

The number of repetitions performed to fatigue is an important consideration in designing a strength training programme. The greatest strength gains appear to result from working with 4-6RM. Increasing this to 12-20RM favours the increase in muscle endurance and mass.. One set of 4-6RM performed 3 days a week is a typical strength training programme. The optimal number of sets of an exercise to develop muscle strength remains controversial. In a number of studies comparing multiple set programmes to produce greater strength gains than a single set, the majority of studies indicate that there is not a significant difference.. Handling heavy weights in the pursuit of strength will require a recovery of 3-5 minutes between sets, but only minimum recovery should be taken if strength endurance is the aim. The majority of athletic events are fast and dynamic, and therefore this quality must be reflected in the athletes strength work. Muscular strength is primarily developed when 8RM or less is used ...

The effects of 24 wk of resistance training combined with a healthy diet on lower limb explosive strength capacity were investigated in a population of healthy elderly women. Participants (n = 63; 67.5 ± 0.4 yr) were randomized into three groups; resistance training (RT), resistance training and healthy diet (RT-HD), and control (CON). Progressive resistance training was performed at a load of 75-85% one-repetition maximum. A major adjustment in the healthy dietary approach was an n-6/n-3 polyunsaturated fatty acid (PUFA) ratio below 2. Lower limb maximal strength, explosive force capacity during dynamic and isometric movements, whole body lean mass, and physical function were assessed. Whole body lean mass significantly increased by 1.5 ± 0.5% in RT-HD only. Isometric strength performance during knee extension as well as the performance in the five sit-to-stand and single-leg-stance tests increased similarly in RT and RT-HD. Improvements in dynamic peak power and time to reach peak power (i.e ...

PMID: Nutrients. 2018 Feb 16 ;10(2). Epub 2018 Feb 16. PMID: 29462923 Abstract Title: The Effect of Whey Protein Supplementation on the Temporal Recovery of Muscle Function Following Resistance Training: A Systematic Review and Meta-Analysis. Abstract: Whey protein (WP) is a widely consumed nutritional supplement, known to enhance strength and muscle mass during resistance training (RT) regimens. Muscle protein anabolism is acutely elevated following RT, which is further enhanced by WP. As a result, there is reason to suggest that WP supplementation may be an effective nutritional strategy for restoring the acute loss of contractile function that occurs following strenuous RT. This systematic review and meta-analysis provides a synthesis of the literature to date, investigating the effect of WP supplementation on the recovery of contractile function in young, healthy adults. Eight studies, containing 13 randomised control trials (RCTs) were included in this review and meta-analysis, from which ...

TY - JOUR. T1 - Rhabdomyolysis after performing blood flow restriction training. T2 - A case report. AU - Tabata, Shogo. AU - Suzuki, Yukio. AU - Azuma, Koichiro. AU - Matsumoto, Hideo. PY - 2016/7/1. Y1 - 2016/7/1. N2 - Rhabdomyolysis is a serious and potentially life-threatening condition related to resistance training. Despite numerous reports of low-intensity blood flow restriction (BFR) training inducing muscle hypertrophy and increasing strength, few reports of rhabdomyolysis related to BFR training have been published. Here, we report a 30-year-old obese Japanese man admitted to our hospital the day after his first BFR training session with complaints of severe muscle pain in his upper and lower extremities, high fever, and pharyngeal pain. He was diagnosed with acute rhabdomyolysis based on a serum creatine phosphokinase level of 56,475 U·L -1 and a urine myoglobin level of ,3,000 ng·ml -1, and with acute tonsillitis based on a white blood cell count of 17,390 and C-reactive protein ...

The effects of resistance training on serum levels of myostatin and GASP-1, may explain the increased muscle mass that is amplified by creatine supplementation. Myostatin is a catabolic regulator of skeletal muscle mass. The purpose of this study was to determine the effect of resistance training for 8 weeks in conjunction with creatine supplementation on muscle strength, lean body mass, and serum levels of myostatin and growth and differentiation factor-associated serum protein-1 (GASP-1). In a double-blinded design 27 healthy male subjects (23.42+/-2.2 years) were assigned to control (CON), resistance training+placebo (RT+PL) and resistance training+creatine supplementation (RT+CR) groups. The protocol consisted of 3 days per week of training for 8 weeks, each session including three sets of 8-10 repetitions at 60-70% of 1 RM for whole-body exercise. Blood sampling, muscular strength testing and body composition analysis (full body DEXA) were performed at 0, 4th and 8th weeks. Myostatin and GASP-1 was

Aging is associated with an increase in fat mass which increases the risk for disease, morbidity and premature mortality. Creatine supplementation in combination with resistance training has been shown to increase lean tissue mass in adults ≥50 years of age; however, the synergetic effects of creatine and resistance training on fat mass in this population are unclear. Creatine metabolism plays an important role in adipose tissue bioenergetics and energy expenditure. Thus, the combination of creatine supplementation and resistance training may decrease fat mass more than resistance training alone. The purpose of this review is two-fold: (1) to perform meta-analyses on studies involving creatine supplementation during resistance training on fat mass in adults ≥50 years of age, and (2) to discuss possible mechanistic actions of creatine on reducing fat mass. Nineteen studies were included in our meta-analysis with 609 participants. Results from the meta-analyses showed that adults ≥50 years of age

Resistance training and weightlifting are regarded as safe and effective training methods for youth. However, no studies have examined the effects of a year-long resistance training program using weightlifting movements on strength, speed or power. Therefore, the purpose of this study was to determine the long-term effects of combined resistance training (traditional strength training + plyometrics) with or without weightlifting movements on motor skill performance of adolescent males. Fifty-nine males aged 12-14 were matched by maturity and allocated to a combined resistance training or a combined resistance training with weightlifting group. Each group completed 28 total weeks of training over an academic year. Pre-, mid- (14 weeks of training) and post-training (28 weeks of training) tests included the Resistance Training Skills Battery quotient (RTSQ), absolute isometric mid-thigh pull peak force (IMTPABS) and ratio scaled isometric mid-thigh pull peak force (IMTPREL), countermovement jump, ...

Low- to moderate-intensity exercise has been widely recommended for people at any age to improve cardiovascular health due to its positive effects on blood lipids and lipoproteins. Recently, many people have been participating in not only low- to moderate-intensity, but high-intensity exercise as well in order to improve their cardiovascular health. However, it is unclear whether high-intensity exercise, particularly resistance exercise, can positively influence blood lipids and lipoproteins. Purpose: The current study examined the effects of low- and high-intensity of resistance exercise on changes in blood lipids and lipoproteins. Methods: In a randomized, cross-over design, 10 healthy recreationally resistance-trained (at least 3 to 6 days per week for a minimum of one year) college-aged men participated in the study. The participants performed a lower body resistance exercise, consisting of the leg press and unilateral knee extension, at two different exercise intensities (low-intensity: 50% of 1-RM

Purpose: There is conflicting evidence whether a single bout of resistance exercise performed the day before a test meal can lower postprandial triacylglycerol (TAG) concentrations. The present study examined the effect of a single session of resistance exercise, performed the same day as a test meal, on postprandial TAG concentrations in resistance-trained males.. Methods: Ten healthy males aged 25 (SD 2.6) yr performed two trials at least 1 wk apart in a counterbalanced, randomized design. In each trial, participants consumed a test meal (0.89 g of fat, 1.23 g of carbohydrate, 0.4 g of protein, 60 kJ.kg-1 body mass). Before one meal, participants performed a 90-min bout of resistance exercise. Before the other meal, participants were inactive (control trial). Resistance exercise was performed using free weights and included three sets of 12 repetitions of each of 10 exercises. Sets were performed at 80% of 12-repetition maximum with a 3-min work and rest interval. Venous blood samples were ...

Background The neuromuscular decline impact in the functional independence of older women is determining the necessity of implementing new strategies focused on core strength training and postural stability maintenance to promote healthy aging. Objectives To define whether Pilates or resistance training is better at improving (a) core isometric and isokinetic muscular strength, and (b) static and dynamic balance, in older women. Methods This was a cluster randomized controlled trial. Physically independent older women (60-80 years) from day centers were randomly allocated to Pilates, Muscular and Control Groups (PG, MG and CG) using a block randomization method. Only the research staff performing the assessment and statistical analysis were blinded. Exercise groups trained twice a week (1 h per session) for 18 weeks in a moderate-to-vigorous intensity. Core strength (primary outcome): trunk and hip isometric and hip isokinetic muscular strength (Biodex System III Pro Isokinetic Dynamometer), alongside

This is the first study to examine the effects of resistance exercise on IHL and its mediators in adults with NAFLD. An 8-week resistance exercise programme brought about an approximately 13% reduction in liver fat. This was accompanied by an approximately 12% increase in insulin sensitivity, and increased fat oxidation during submaximal exercise in the absence of any change in body weight.. Although lifestyle modification combining dietary change and exercise produces a robust reduction in IHL,1 the data on exercise alone is less definitive. We demonstrated that resistance exercise without weight change is effective in reducing IHL in people with NAFLD. Resistance exercise provides an alternative to aerobic exercise; it improves muscular strength, muscle mass and metabolic control, safely and effectively, in vulnerable populations independent of weight loss.16 It places less of a demand on the cardiorespiratory system and may therefore be accessible to more patients.17 All participants ...

Weight training usually refers to exercises done with free weights, barbells, and weight machines. Strength training may include weight training, but also work with resistance cables, core strength exercises such as situps and leg lifts, exercises that use the bodys own weight such as pull-ups and push-ups, and many other types of weight-bearing exercise. Bodybuilding is an extreme form of strength training designed to develop enormous muscles rather than simply increasing overall strength and fitness.. The following articles cover strength training basics such as sets, repetitions, workout frequency, training supplements, and other issues, as well as the health and fitness benefits of strength training. At the bottom of the page are links to websites that provide demonstrations of weight and strength training exercises.. ...

Background & Aims: Endothelin_1 secreted by endothelial cells has been identified as the strongest vascular constrictor. The aim of the present study was to investigate the role of concurrent training on plasma concentration of endothelin_1 and its relationship with blood pressure of old women. Methods: A total of 20 menopause women (Mean age: 67.47±5.92 years, mean body length: 152.92±7.52cm, mean weight: 65.83±11.83 kg, mean BMI 28.47±4.98 kg/m2 , fat percentage: 18.61±3.57, and WHR: 0.929±0.045) were selected purposefully and randomly assigned into the two groups of ten people. The experimental group did eight weeks of concurrent training in the form of three days per week each day two sessions resistance training with the intensity of 40 to 65% of one maximum repetition and with overload of 5% after each 6 sessions and aerobic training with 60 to 70% of maximum heart rate. Before and after eight weeks of exercise, the resting level of endothelin_1 and systolic and diastolic blood pressure were

Kevin Levrone was known for taking months off from the gym after competing, losing a great deal of body weight in the process. How much time is OK to take off from the gym without losing muscle and strength? Researchers randomly divided young men into either a continuous resistance training group or a periodic resistance-training group (i.e., taking a break). Both groups performed freeweight bench presses three days per week. The continuous group trained for the entire 24-week period, while the periodic group performed two cycles of a three-week detraining/six-week retraining period after a six-week initial training period. Training intensity was set at 75% one-rep max (1RM), and the subjects did three sets of 10 with 2-3 minutes rest between sets. Before and after the study, the subjects 1RM was assessed. Also, upper arm and chest muscle size were measured using magnetic resonance imaging (MRI). At the end of the study, both groups experienced similar increases in 1RM bench press, and muscle ...

Currently, there is a paucity of investigations that have assessed the effects of RT on LV morphology and systolic function in healthy older individuals. We recently assessed the effects of 16 weeks of upper and lower extremity RT, in previously sedentary healthy older males (mean age: 68 years), on LV morphology, end-systolic meridional wall stress and LV systolic function (26). Resting two-dimensional echocardiograms were performed after 4, 8, 12 and 16 weeks of moderate (60% one repetition maximum, 1RM) to high (80% 1RM) intensity upper and lower extremity RT. The major finding of this investigation was that 16 weeks of RT was a sufficient stimulus to increase upper (+16%) and lower (+29%) extremity maximal muscular strength but was insufficient of a stimulus to alter LV posterior wall thickness, ventricular septal wall thickness, systolic or diastolic cavity dimensions, relative wall thickness and estimated LV mass (26). In addition, this form of training was not associated with an ...

This study determined the effects of 28 days of heavy resistance exercise combined with the nutritional supplement, NO-Shotgun®, on body composition, muscle strength and mass, markers of satellite cell activation, and clinical safety markers. Eighteen non-resistance-trained males participated in a resistance training program (3 × 10-RM) 4 times/wk for 28 days while also ingesting 27 g/day of placebo (PL) or NO-Shotgun® (NO) 30 min prior to exercise. Data were analyzed with separate 2 × 2 ANOVA and t-tests (p | 0.05). Total body mass was increased in both groups (p = 0.001), but without any significant increases in total body water (p = 0.77). No significant changes occurred with fat mass (p = 0.62); however fat-free mass did increase with training (p = 0.001), and NO was significantly greater than PL (p = 0.001). Bench press strength for NO was significantly greater than PL (p = 0.003). Myofibrillar protein increased with training (p = 0.001), with NO being significantly greater than PL (p = 0.019).

The 12-wk whole body resistance training program involved 13 guided-motion resistance exercises divided over 3 different training days, as previously described (8). Briefly, training days were divided into legs (leg press, leg curl, leg extensions, and standing calf raises), pushing exercises (seated military press, bench press, vertical bench press, chest fly, and seated machine triceps extensions), and pulling (latissimus pull-down, seated wide-grip row, seated narrow low row, and seated biceps curl) exercises. One repetition maximum (1 RM) was measured for each exercise before training and 2-4 d after the last training session to evaluate strength changes. Participants trained 5 d/wk at an initial intensity of ∼70% of the pretraining 1 RM with a goal of 2 sets of 10-12 repetitions during the first 2 wk. In wk 3-12, exercise intensity was adjusted to ∼80-85% 1 RM so that 3 sets of 6-10 repetitions were performed. All training sessions were supervised by a study investigator to ensure ...

In Part Three we have some FAQs and a last little tip to finish off this three part article! Enjoy!. FAQs. Which should I do first, Weights or Cardio?. Always perform weights before cardio where possible. If you perform cardio exercise before weights training you will fatigue your muscles which will lead to a less effective resistance training session. On top of this, if your muscles are fatigued before starting, you are opening yourself up to potential injuries.. How long should I perform resistance training for?. Everyone has that friend who comes back from the gym and boasts I just spent 2.5 hours in the gym doing bench press and squats (as well as a whole bunch of useless exercises). I do not want you to be that person. Spending too much time in the gym performing resistance training can actually have a catabolic (negative) effect on muscle growth. By performing resistance training for too long, your body will start releasing increased levels of the stress hormone Cortisol, which will ...

Resistance training (RT) is a powerful first-line intervention for the management of type 2 diabetes mellitus (T2DM). Nonetheless, the effects of the most frequent RT (hypertrophy training [HT] and muscular endurance training [MERT]) employed for the management of T2DM, and which type of RT might exert superior effects, remain elusive. Thus, this review aims to assess the effects of HT and MERT on glycaemic control, physical fitness, body composition, lipid profile, blood pressure, C-reactive protein, and quality of life in patients with T2DM; to analyse which particular RT is more effective; to assess the effects of general RT; and to identify RT components, characteristics of patients, and medications that could mediate the effects of RT. Randomized controlled trials (RCT) and non-RCT (RT≥ 4 weeks) in adults with T2DM were selected. Both HT and MERT improved HbA1c, insulin levels and sensitivity, muscle strength, body mass index, waist circumference, and fat mass. Additionally, HT improved ...

The objective of this study was to determine the efficacy of pre- and post-RT supplementation with MIPS on body composition, muscle strength, and power in resistance-trained men participating in a six-week periodized RT program. With this specific population, any gains in strength should be almost entirely due to physiological and hypertrophic changes to the trained muscles, rather than improvements in neuromuscular coordination. Shelmadine et al. [14] noted large increases in markers of satellite cell activation and hypertrophy, and modest increases in LM (4.8%) for their MIPS group after only four weeks in untrained men. By increasing the time course and total volume of training in the present study, we aimed to augment the opportunity for muscle growth. In addition to ingesting SHOT before exercise, our participants also consumed one serving of SYNTH immediately post-exercise and on every non-training day. This supplementation model, similar to that used by Spillane et al. [21], provided a ...

Plus, the authors found that almost 70 percent of patients in the studies still reported feeling down for up to 14 weeks after starting therapy -- and close to a third of patients had to try four different medications to get relief. Researchers from Ireland and Sweden pooled the data from 1,877 patients and 33 randomized clinical trials measuring how resistance training affects mood. The patients worked out, 3 sessions per week, for an average of 16 weeks. The intensity of the exercise was mixed, but it wasnt an Olympic effort -- most were putting in low to moderate effort, and ranged in age from their 20s to their 80s. Resistance training -- everything from arm raises and leg lifts to weight training -- alleviated depression symptoms, study participants said. The largest gains were made by patients who reported mild to moderate depression. The analysis was limited in some ways. These were a mix of studies and not every study had the same forms of resistance training or the same amount of ...

It is widely accepted that strength training must be matched by changes in diet in order to be effective. Although aerobic exercise has been proven to have an effect on the dietary intake of macronutrients, strength training has not [48] and an increase in dietary protein is generally believed to be required for building skeletal muscle. A review of 49 research studies found that supplementation of protein in the diet of healthy adults increased the size and strength of muscles during prolonged resistance exercise training; protein intakes of greater than 1.6 g/kg/day did not additionally increase fat-free mass or muscle size or strength.[49] Protein that is neither needed for cell growth and repair nor consumed for energy is converted into urea mainly through the deamination process and is excreted by the kidneys. It was once thought that a high-protein diet entails risk of kidney damage, but studies have shown that kidney problems only occur in people with previous kidney disease. However ...

Introduction. After a single bout of resistance exercise, blood pressure (BP) decreases to levels lower than in the pre-exercise period, which is known as post-exercise hypotension (FORJAZ et al., 2004; FORJAZ et al., 1998; FORJAZ et al., 2000). This phenomenon occurs in normotensive and hypertensive subjects and although it has clinical importance for the latter (PESCATELLO et al., 2004), it has been extensively studied in the former (CASTINHEIRAS-NETO et al., 2010; MENÊSES et al., 2011; REZK et al., 2006) to understand its behavior in a population with low cardiovascular risk and without pathological influences. Several studies have indicated that the magnitude of post-exercise hypotension is affected by the resistance exercise method. Current data suggest that post-exercise hypotension is greater after multiple sets of resistance exercise for the major muscle groups (MEDIANO et al., 2005; POLITO; FARINATTI, 2009). Despite this evidence, the impact of other resistance exercise variables on ...

With weight training, the female sees some remarkable gains in strength initially, even though muscle bulk does not increase. For a muscle to contract, an impulse must be transmitted from the nervous system to the muscle. Each muscle fiber is innervated by a specific motor unit. By overloading a particular muscle, as in weight training, the muscle is forced to work efficiently. Efficiency is achieved by getting more motor units to fine, causing a stronger contraction of the muscle. Consequently, it is not uncommon for a female to see extremely rapid gains in strength when a weight training program is first begun. These tremendous initial strength gains, which can be attributed to improved neuromuscular system efficiency, tend to plateau, and minimum improvement in muscular strength will be realized during a continuing strength - training program, These initial neuromuscular strength gains will also be seen in men, although their strength will continue to increase with appropriate training. ...

Multiple component community-wide campaigns are frequently used in an attempt to increase a populations level of physical activity. A 2015 Cochrane review, however, did not find evidence supporting a benefit.[124] The quality of the underlying evidence was also poor.[124] However, there is some evidence that school-based interventions can increase activity levels and fitness in children.[16] Another Cochrane review found some evidence that certain types of exercise programmes, such as those involving gait, balance, co-ordination and functional tasks, can improve balance in older adults.[125] Following progressive resistance training, older adults also respond with improved physical function.[126] Survey of brief interventions promoting physical activity found that they are cost-effective, although there are variations between studies.[127] Environmental approaches appear promising: signs that encourage the use of stairs, as well as community campaigns, may increase exercise levels.[128] The ...

Spaceflight and bed rest (BR) lead to muscle atrophy. This study assessed the effect of essential amino acid (EAA) supplementation and resistance training with decreased energy intake on molecular changes in skeletal muscle after 28-day BR and 14-day recovery. Thirty-one men (31-55 years) subjected to an 8 ± 6% energy deficit were randomized to receive EAA without resistance training (AA, n = 7), or EAA 3 h after (RT, n = 12) or 5 min before (AART, n = 12) resistance training. During BR, myostatin transcript levels increased twofold in the AA group. During recovery, insulin-like growth factor-1 (IGF-1) mRNA increased in all groups, whereas Pax7, MyoD, myogenin, and MRF4 transcripts increased in AA only (all P , 0.05). MAFbx transcripts decreased twofold with AA and RT. Satellite cells did not change during BR or recovery. This suggests that EAA alone is the least protective countermeasure to muscle loss, and several molecular mechanisms are proposed by which exercise attenuates muscle atrophy ...

Blood was also drawn immediately before and ~ 10 min after a single exercise session ...

As training experience increases it becomes more challenging to induce further neuromuscular adaptation. Consequently, strength trainers seek alternative training methods in order to further increase strength and muscle mass. One method is to utilize accentuated eccentric loading, which applies a greater external load during the eccentric phase of the lift as compared to the concentric phase. Based upon this practice, the purpose of this study was to determine the effects of 10 weeks of accentuated eccentric loading vs. traditional isoinertial resistance training in strength-trained men. Young (22 ± 3 years, 177 ± 6 cm, 76 ± 10 kg, n = 28) strength-trained men (2.6 ± 2.2 years experience) were allocated to concentric-eccentric resistance training in the form of accentuated eccentric load (eccentric load = concentric load + 40%) or traditional resistance training, while the control group continued their normal unsupervised training program. Both intervention groups performed three sets of 6-RM
