Endurance exercise capacity diminishes under hot environmental conditions. Time to exhaustion can be increased by lowering body temperature prior to exercise (pre-cooling). This systematic literature review synthesizes the current findings of the effects of pre-cooling on endurance exercise performance, providing guidance for clinical practice and further research. The MEDLINE, EMBASE, CINAHL, Web of Science and SPORTDiscus databases were searched in May 2012 for studies evaluating the effectiveness of pre-cooling to enhance endurance exercise performance in hot environmental conditions (≥ 28°C). Studies involving participants with increased susceptibility to heat strain, cooling during or between bouts of exercise, and protocols where aerobic endurance was not the principle performance outcome were excluded. Potential publications were assessed by two independent reviewers for inclusion and quality. Means and standard deviations of exercise performance variables were extracted or sought from

Muscular strength is related to muscular endurance but is not the same.. Muscular endurance is trained specifically and in more of an aerobic and oxygenated pathway, whereas muscular strength is trained in an anaerobic ATP-CP and Glycolytic pathway.. There does seem to be a relationship between muscular strength and muscular endurance. However if a person only trains to improve strength then that person is not improving his muscular endurance that much.. The definition of muscular strength is: the ability of your bodys muscle to generate force in a short period of time. This type of activity relies on anaerobic energy-allowing you the short burst of energy you need to lift a heavy weight. When you increase your strength, youre often also increasing the size of your muscles as well as strengthening your connective tissues.. On the other hand the definition of muscular endurance is: the ability to sustain muscle contraction over a period of time without undue fatigue.. By looking at these ...
The neuropathic pain model of systemic injection of STZ was performed in this study to investigate chronic effects of increased activity in the form of endurance exercise on behavioral response of neuropathic pain. The obtained results from this study showed that increased activity in the form of moderate endurance exercise can improve neuropathic pain responses in mechanical allodynia and thermal hyperalgesia. This result is consistent with some studies suggesting the significant effects of exercise training on neuropathic pain responses in various pain models (11, 15). Conversely, some studies have failed to confirm the effects of exercise training on improvement of neuropathic pain (17). The reason for the difference could be due to difference in type of pain creation model (15, 17). The present study showed that moderate intensity exercise training caused a significant reduction in blood glucose levels in diabetes exercise group. Since muscles are the most common place for consumption of ...
It has been proposed that high exercise loads increase the risk of infection, most frequently reported as upper respiratory tract infections, by suppressing the immune system. Most athletes will not train when experiencing sickness due to the fear of health complications. However, high training volumes are incompatible with high rates of non-training days, regardless of the cause. The purpose of this observational study was to examine the relationship between self-reported, exercise-constraining days of sickness (days when the athlete decided not to train due to symptoms of disease, either self-reported or by a physician) and the volumes of exercise training in elite endurance athletes by analyzing data from training logs kept for several years. The subjects included 11 elite endurance athletes (8 male, 3 female) competing at national and international levels in cross-country skiing, biathlon and long-distance running. Training logs available from these 11 subjects added to a total of 61 ...
The genetic profile that is needed to define an endurance athlete has been studied during recent years. The main objective of this work is to approach for the first time the study of genetic variants in liver-metabolizing genes and their role in endurance performance by comparing the allelic and genotypic frequencies in elite endurance athletes to the non-athlete population. Genotypic and allelic frequencies were determined in 123 elite endurance athletes (75 professional road cyclists and 48 endurance elite runners) and 122 male non-athlete subjects (sedentary). Genotyping of cytochrome P450 family 2 subfamily D member 6 (CYP2D6 rs3892097), glutathione-S transferase mu isoform 1 (GSTM1), glutathione S-transferase pi (GSTP rs1695) and glutathione S-transferase theta (GSTT) genes was performed by polymerase chain reaction (PCR). The combination of the polymorphisms for the

Large quantities of data have described left ventricular adaptation to endurance training, but basic concepts on left ventricular performance during exercise remain controversial. In this thesis, we present the results of studies of left ventricular dynamics during exercise in 89 endurance-trained athletes.. Using radionuclide ventriculography, 35 female and 30 male endurance athletes were studied in supine position. During supine exercise at 70% of the age-expected maximal heart rate, the adjustments in left ventricular volumes were small, suggesting a high preload before exercise. Stroke volume increased by changes in the left ventricular end-diastolic volumes but no changes were observed in the end-systolic volumes. Moreover, no significant differences were noted between male and female athletes.. Contrast echocardiography was utilized when 24 male endurance athletes were studied during upright exercise. An almost linear increase in stroke volume was seen from upright rest to upright exercise ...

Background Regular exercises decrease the risk of various diseases. This is a reason to recommend exercises for health promotion. Thus American Heart Association (AHA) and American College of Sport Medicine (ACSM) have issued guidelines for young people resistance exercises. Aim: To investigate the effect of resistance training exercise on hematological, immunological and coagulation parameters in sedentary young men. Methods: This quasi- experimental study was carried out on 26 healthy men (21.5±1.6 years old) who were selected at Bu-Ali Sina University and randomly assigned to control (n=13) and experimental (n=13) groups. The experimental group did AHA-ACSM exercise at 8 A.M. and control group continued their regular activities for 12 weeks. Fasting blood (5ml) was collected from antecubital vein before and 72 hours after exercise training. Hematological, immunological and coagulation parameters were measured by cell counting and ELISA methods. Data were analyzed by SPSS version 15 using t student
Background: Given widespread deleterious health effects of an augmented inflammatory state, identification of therapies that reduce inflammation is critical. The purpose of the present study was to investigate the effects of 10 weeks endurance training on pro-inflammatory cytokines and their relationships with cortisol and testosterone hormones in sedentary young men. Methods: Twenty sedentary men (age, 20-30 yr), volunteers to participant in the study. They were randomly divided into two groups of endurance training (n=11) and control (n=9) group. Blood sample were collected before and after 5 and 10 weeks from intervention, and the concentrations of TNF-a, IL-1b, IL-6, cortisol and testosterone were measured. Endurance training included 30 min cycling on ergometer at 70% maximal heart rate, which was then increasingly changed to 50 min at 80% maximal heart rate in week 10. Results: Endurance training increased VO2max, and decreased body fat percent (P,0.05), but concentrations of TNF-a, IL-1b, ...
The physical endurance is the ability of the body to perform an action or effort over a long period of time (aerobic endurance). The aim of the exercises of aerobic endurance is to increase cardio vascular capacity, to be able to perform a moderate effort for as long as possible without affecting the performance.

Regular physical activity positively influences whole body energy metabolism and substrate handling in exercising muscle. While it is recognized that the effects of exercise extend beyond exercising muscle, it is unclear to what extent exercise impacts non-exercising muscles. Here we investigated the effects of an acute endurance exercise bouts on gene expression in exercising and non-exercising human muscle. To that end, 12 male subjects aged 44-56 performed one hour of one-legged cycling at 50% Wmax. Muscle biopsies were taken from the exercising and non-exercising leg before and immediately after exercise and analyzed by microarray. One-legged cycling raised plasma lactate, free fatty acids, cortisol, noradrenalin, and adrenalin levels. Surprisingly, acute endurance exercise not only caused pronounced gene expression changes in exercising muscle but also in non-exercising muscle. In the exercising leg the three most highly induced genes were all part of the NR4A family. Remarkably, many genes ...

Central arterial stiffness is an independent predictor of cardiovascular risk that can be modified by exercise training. However, conventional local measures of carotid artery stiffness display conflicting responses to habitual endurance exercise in young and older adults. 2D-Strain imaging of the common carotid artery (CCA) quantifies circumferential deformation (strain) of the arterial wall across the cardiac cycle, which is more sensitive at detecting age-related alterations in CCA stiffness than conventional methods. Therefore, the study was designed to examine the relationship between habitual endurance exercise (running) and CCA 2D-Strain parameters in young and middle-aged men. Short-axis ultrasound images of the CCA were obtained from 13 young nonrunners (23 years [95% CI: 21-26]), 19 young runners (24 [22-26]), 13 middle-aged nonrunners (54 [52-56]) and 19 middle-aged runners (56 [54-58]). Images were analysed for peak circumferential strain (PCS; magnitude of deformation) as well as ...
Despite a low recruitment rate, findings from an article published online last week in Archives of Physical Medicine and Rehabilitation suggest that moderate-intensity endurance exercise training is feasible in patients with small abdominal aortic aneurysm (AAA), and can evoke improvements in important health outcomes.. For this study conducted in the United Kingdom, researchers randomized 28 patients with small AAA (age 72 ± 7 years; mean ± SD) to a 12-week program of moderate-intensity endurance exercise or standard care control (encouragement to exercise only). They assessed safety in terms of the frequency of adverse events and changes in maximum AAA diameter. Outcomes were assessed at baseline and 12 weeks, including cardiopulmonary fitness (ventilatory threshold), health-related quality of life (SF-36v2), and markers of vascular risk (blood pressure and High Sensitivity C-reactive Protein [hs-CRP]). Adherence to the exercise program was 94%. There were no paradoxical increases in AAA ...

Przyklenk, A, Aussieker, T, Gutmann, B, Schiffer, T, Brinkmann, C, Strüder, HK, Bloch, W, Mierau, A, and Gehlert, S. Effects of endurance exercise bouts in hypoxia, hyperoxia, and normoxia on mTOR-related protein signaling in human skeletal muscle. J Strength Cond Res XX(X): 000-000, 2018-This study investigated the effects of short-term hypoxia (HY), hyperoxia (PER), and normoxia on anabolic signaling proteins in response to an acute bout of moderate endurance exercise (EEX) before and after an endurance exercise training intervention. Eleven healthy male subjects conducted one-legged cycling endurance exercise (3 × 30 min·wk for 4 weeks). One leg was trained under hypoxic (12% O2) or hyperoxic conditions (in a randomized cross-over design), and the other leg was trained in normoxia (20.9% O2) at the same relative workload. Musculus vastus lateralis biopsies were taken at baseline (T0) as well as immediately after the first (T1) and last (T2) training session to analyze anabolic signaling ...
This study demonstrates that the 2-week novel MAX dietary intervention provided no additional benefits to inflammatory control or hepcidin activity following a 26-km standardized race walking protocol, compared with a more moderate CHO intake. This outcome is in agreement with some of our previous work, indicating that chronic macronutrient manipulations may not have a strong influence on iron regulation in elite endurance athletes (McKay et al., 2019b). Instead, it appears that resting iron status (serum ferritin concentrations) and environmental conditions (ambient temperature) had a larger influence on the increase in hepcidin levels 3 hr postexercise than dietary CHO intake.. A similar decrease in iron status (determined via serum ferritin) was evident after 2 weeks in both the CON (−23%) and MAX (−17%) group. This short-term reduction in serum ferritin occurred, despite dietary iron intakes being well above the recommended daily intake of 8 mg/day for males in both groups (Trumbo et ...

Improvements in early diagnosis and treatment for breast cancer in women have resulted in increased survivorship. An unintended consequence of increased survival, however, is that more women are living with the negative sequelae associated with cancer treatment, including decreased physical function. Exercise has been beneficial in arresting these sequelae, but adherence to exercise guidelines continues to be a challenge. As most breast cancer survivors are middle-aged and older, an alternative to enhance exercise engagement and adherence might be providing a low intensity exercise program. The overall purpose of this study is to assess the impact of a low intensity versus moderate intensity endurance exercise program on physical functioning on breast cancer survivors. It is hypothesized that participants of the low intensity exercise program will demonstrate similar physical functioning as participants in the moderate intensity exercise program. The Theory of Planned Behavior will serve as ...
Aims The aims of the study were to explore the effects of long-term endurance exercise on atrial and ventricular size and function in adolescents and to examine whether these changes are related to maximal oxygen uptake (VO2max). Methods and results Twenty-seven long-term endurance-trained adolescents aged 13-19 years were individually matched by age and gender with 27 controls. All participants, 22 girls and 32 boys, underwent an echocardiographic examination at rest, including standard and colour tissue Doppler investigation. VO2max was assessed during treadmill exercise. All heart dimensions indexed for body size were larger in the physically active group compared with controls: left ventricular end-diastolic volume 60 vs. 50 mL/m(2) (P amp;lt; 0.001), left atrial volume 27 vs. 19 mL/m(2) (P amp;lt; 0.001), and right ventricular (RV) and right atrial area 15 vs. 13 and 9 vs. 7 cm(2)/m(2), respectively (P amp;lt; 0.001 for both). There were strong associations between the size of the cardiac ...
Data analysis revealed that 5 of 10 LHTL subjects did increase Hbmass, suggesting a significant variability among athletes with regard to the haematological response to hypoxia, and that moderate hypoxia may provide, at least in some athletes, a sufficient stimulus for red blood cell synthesis to be increased. Similarly, Chapman et al19 found that only 53% (17 of 32 subjects) exhibited an expansion of RCV in response to altitude training. The different Hbmass response among our LHTL subjects was not explained by the degree of haemoconcentration or by the increase of reticulocyte count. Also an increase in Hbmass following LHTL was not accompanied by a concomitant rise in VO2max, confirming previous data,9 which questions the significance of the small Hbmass improvements detected in athletes undergoing the LHTL regimen. Of note, after blood transfusion, only 50% of the added O2 delivery may be utilised by the tissues.32 Nevertheless, it could be that highly trained individuals require a larger ...
Endurance-trained athletes have higher large-artery compliance than do their sedentary counterparts [30], and training improves arterial stiffness in healthy young [31] and elderly subjects [32, 33]. However, the effects of exercise training on arterial stiffness in elderly patient populations are contradictory [34-38]. This issue is further complicated by the heterogeneity among studies in modality, frequency and duration of exercise training, and in the assessment method for arterial stiffness.. Vivodtzev et al. [12] were the first to show significant improvements in brachial pulse wave velocity in 10 patients with COPD who underwent a 4-week aerobic endurance training programme. Peripheral (brachial) muscular arteries are more susceptible to modification by exercise training than central (aortic) elastic arteries [39]. Indeed aortic stiffening is more attributable to elastin degradation and is largely irreversible [40]. Moreover, APWV is the gold standard for measurement of arterial stiffness ...
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 ...

We tested the hypothesis that heliox breathing, by reducing lung dynamic hyperinflation (DH) and dyspnea (Dys) sensation, may significantly improve exercise endurance capacity in patients with chronic obstructive pulmonary disease [n = 12, forced expiratory volume in 1 s = 1.15 (SD 0.32) liters]. Each subject underwent two cycle ergometer high-intensity constant work rate exercises to exhaustion, one on room air and one on heliox (79% He-21% O2). Minute ventilation (VE), carbon dioxide output, heart rate, inspiratory capacity (IC), Dys, and arterial partial pressure of CO2 were measured. Exercise endurance time increased significantly with heliox [9.0 (SD 4.5) vs. 4.2 (SD 2.0) min; P , 0.001]. This was associated with a significant reduction in lung DH at isotime (Iso), as reflected by the increase in IC [1.97 (SD 0.40) vs. 1.77 (SD 0.41) liters; P , 0.001] and a decrease in Dys [6 (SD 1) vs. 8 (SD 1) score; P , 0.001]. Heliox induced a state of relative hyperventilation, as reflected by the ...
The purpose of this study was to examine the effect of short-term training on maximum oxygen uptake (VO2 max) and two different measures of endurance performance. Endurance was determined for 15 female subjects (7 training, 8 control) as (1) exercise time to exhaustion at 80% VO2 max (T80%) and (2) the highest relative exercise intensity tolerable during a 30-minute test (T30 min), before and after a 6-week training period. In addition, VO2 max and the work rate equivalent to a blood lactate concentration of 4 mmol.l-1 (OBLA) were determined. Maximum oxygen uptake increased by 24% (p less than 0.01) for the training group (TG) and 7% (p less than 0.01) for the control group (CG). Cumulative average work rate (CAWR) during T30 min increased by 25% for the TG while there was no change for the CG. No significant difference was found pre- and post-training in the %VO2 max (estimated from CAWR) at which the TG and CG performed T30 min. Exercise time to exhaustion on T80% increased by 347% (p less ...
Impaired balance, impaired physical endurance, and pain were estimated to have the largest impact on exercise activities, primarily walking, stair climbing, balance exercises, and stationary bicycling. Impaired physical endurance was estimated to limit 20 minutes of walking in 31% of the participants at a minimal reduction level and 51% of participants at a major reduction level. Impaired balance was rated as limiting balance exercises, with the corresponding percentages of 48% and 42%. Weakness was estimated to have an impact on ability to perform strength training with resistance: hip exercises with resistance in 79% of participants, knee exercises with resistance in 42% of participants, and shoulder exercises in 33% of participants at a minimal or major reduction level. Impairment impact rating on exercise activities was strongly associated with the exercise intensity recommendation. The intensity of the recommended exercise was very low or low for half of the participants for balance ...
The purpose of this study was to evaluate the effects of a circuit training program along with a maintenance program on muscular and cardiovascular endurance in children in a physical education setting. Seventy two children 10-12 years old from four different classes were randomly grouped into either an experimental group (n = 35) or a control group (n = 37) (two classes for each group). After an eight-week development program carried out twice a week and a four-week detraining period, the experimental group performed a four-week maintenance program once a week. The program included one circuit of eight stations of 15/45 to 35/25 seconds of work/rest performed twice. Abdominal muscular endurance (sit-ups in 30 seconds test), upper-limbs muscular endurance (bent arm hang test), and cardiovascular endurance (20-m endurance shuttle run test) were measured at the beginning and at the end of the development program, and at the end of the maintenance program. After the development program, muscular ...
The major finding of this study was that an acute ingestion of 3000mg of AAKG had no effect on upper or lower body 1RM or TLV in either resistance trained or untrained men. The ergogenic benefits of arginine-based supplementation remain equivocal in the literature.. Some authors have reported increases in anaerobic performance [13, 20] and muscular endurance [21] after ingesting arginine-based supplements. However, like our current study, Greer and Jones [22] did not find an ergogenic effect on exercise performance variables following acute ingestion of AAKG. This may suggest that a specific loading period may be necessary for the prospective ergogenic effects of arginine-based supplements to be realized. Specifically, Santos et al. [21] observed a significant increase in muscular endurance after 15days of oral supplementation with L-arginine aspartate (3g/day), while Campbell et al [13] reported significant increases in maximal strength and anaerobic power following 8weeks of oral ...
Physical activity helps maintain health, promotes adaptations of the cardiovascular and neuromuscular systems to increase uptake, transport and utilisation of oxygen for aerobic energy production and improve fatty acid metabolism. Emerging evidence suggests sprint interval training (SIT) may be as effective as endurance exercise. The overall aim was to measure physiological effects of SIT in males and females from the general population. The first objective was to recruit males and females from the general population to complete 12 weeks cycling SIT and monitor changes relating to health and physiological function. The primary outcomes were changes in body fat mass, VO2max, FATmax, knee extensor muscle size, strength, power, fatigue resistance, circulating concentrations of lipoproteins and inflammatory markers. The secondary outcome was a comparison of results between males and females. The second objective was to recruit Masters sprint and endurance runners to complete measurements of health ...
Stress, anxiety and depression are prevalent among truck drivers. There are numerous reasons for this. Truck drivers particularly longhaul truckers work long hours, sleep in the back of a truck and typically fail to get a sufficient amount of sleep. Longhaul drivers are away from home so much of the time and this often takes a toll on their family lives. There is also the pressure of keeping pick-up and delivery appointments and getting to their destinations safely each day. These are just some of the reasons so many drivers suffer from stress, anxiety and depression. No foods can increase butt or breast size in a normal, healthy way. however, eating excessive carbohydrates in your diet will increase fat production in the body. This will make the butt and breast size larger, as well as the rest of the body, and only because of fat deposits. I have noticed I eat more, which is noted from some woman, while others feel it curbs their appetite. Again, everyone is different. I find I have a ravenous hunger
maca root pills Maca is a tuber (root) that grows high in the Andes mountains. People indigenous to the area have eaten the roots and fed them to their livestock for thousands of years. Consuming them is reported to have a positive effect on mental acuity, energy levels, libido and fertility. Traditionally, the roots were cooked and eaten in soups or as part of other dishes. In the 1990s, the use of maca roots for health and wellness spread beyond Latin America. It was at this time that powdered maca started being produced in large quantities. Mold Deterrent - 1/4 cup white vinegar, 3/4 cup water, 2 drops Cinnamon Leaf 5 drops Patchouli, 2 Teaspoons Tea Tree & 2 drops Tagettes. Combine all ingredients in a spray bottle. If you already have a buildup of mold or mildew, allow the spray to rest on the surface for a few hours. Wipe with a soft cloth, re-spray the area and let dry without rinsing. The amount ofmaca root powderto take varies person to person. The first thing to keep in mind is that it is a
National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of proteins known as phosphodiesterases (PDEs), enzymes that help regulate cell energy.. These findings may help settle the debate regarding resveratrols biochemistry and pave the way for resveratrol-based medicines. The chemical has received significant interest from pharmaceutical companies for its potential to combat diabetes, inflammation, and cancer. The study appears in the February 3rd issue of the journal Cell [1].. ...

I am planning to send a few Christmas cards this year, but they wont include a review of 2017 from the Phoenix family. So instead, I thought I would write a few blog posts (and include pictures) to review the year.. I came across a note I wrote to myself for individual priorities for this year and thought that I would reflect on some of those across a few posts.. I have been blessed with great health in my mere 30ish years of life, but the last couple had been a bit of a struggle, with no real answers on what exactly what was going on. It was rather frustrating to try and fix something when there werent clear conclusions on why I was feeling so terrible.. In May, I finally got my answer when I landed in the ER with a gallbladder attack. Thankfully a church member was able to rush me to urgent care and some great EMTs got me to the hospital quickly where Jack met me.. ...

UA Team,. I am currently running on average ~75 miles per week with approximately 9k-10k of vert per week with peak weeks at ~90 miles with 12-15k of climbing per week. My focus this season has been runnable ultra distance trail races (i.e. 50M with 8-10k of climbing). While there are occasional hiking stretches, Im running 90%+ of the time. Ive focused my training primarily on improving running economy (i.e. strides/pick-ups, flatter tempo runs), furthering aerobic development (long Z1/Z2 days), and Z3 uphill efforts (2×20 or 4×10 minutes) with some Z4 sprinkled in as well (2-5 minute repeats aiming for 15-20 minutes at intensity). Ive used the Muscular Endurance routines in the past when I was running lower mileage and/or didnt have access to runnable climbing terrain. However, Ive stopped using these routines and leaned into more vert and more miles. Ill adapted versions of these workouts (higher weight, lower reps) once or twice a week.. Im wondering if anyone has feedback for at ...

The primary symptom in patients with chronic HFpEF, even when well compensated, is severe exercise intolerance; this symptom is associated with reduced quality of life (4). Only endurance exercise training has been shown to improve exercise capacity in these patients, as standard medications tested to date have proven ineffective (5-8,10). Increased NO bioavailability has been suggested to partially account for the efficacy of exercise training (16). Our study is the first to examine the safety and efficacy of 1 week of daily doses with dietary nitrate in older patients with HFpEF. The major new findings of this study are that: 1) BRJ supplementation was feasible and safe; 2) 1 week of daily doses improved submaximal aerobic endurance; and 3) both the single, acute and 1 week of daily doses reduced resting systolic blood pressure, tended to decrease exercise systolic blood pressure, and increased circulating plasma levels of NO3- and NO2-. These results suggest that 1 week of daily BRJ ...

Endurance athletes often believe the more they train, the better the results. But according to the NSCAs Ben Reuter, recovery time is just as important when developing an effective endurance training program.
<I>Objective.</I> To determine the effect of prolonged endurance exercise on the serum concentrations of eosinophil cationic protein (ECP), immunoglobulin E (IgE) and upper respiratory tract symptoms (URTS). <br><I>Design.</I> In 11 healthy, experienced volunteers (6 males, 5 females, age 43 <u>+</u> 9.8 years) the serum concentrations of ECP and IgE were measured, 24 hours prior to projected finishing time, immediately post exercise (IPE), and 3 h, 24 h, and 72 h after an ultramarathon (90 km). Self-reported URTS were also recorded for 14 days after the race. ECP was measured using radioimmunoassay and IgE using the Alastat Microplate Total IgE kit. The after-exercise values were corrected for plasma volume changes, which were calculated from haematocrit and haemoglobin values. Serum concentrations of ECP and IgE were analysed using an analysis of variance (ANOVA) comparing values with
Oxidative stress is a key feature in the pathophysiology of sickle cell disease. Endurance training has been shown to reduce oxidative stress in the heart and the liver of sickle mice. However, the effects of endurance training on skeletal muscles, which are major producers of reactive oxygen species during exercise, are currently unknown. The aim of this study was to evaluate the effect of sickle genotype on prooxidant/antioxidant response to individualized endurance training in skeletal muscles of sickle mice. Healthy and homozygous Townes sickle mice were divided into trained or sedentary groups. Maximal aerobic speed and V̇O|sub|2|/sub| peak were determined using an incremental test on a treadmill. Trained mice ran at 40% to 60% of maximal aerobic speed, 1 h/day, 5 days/week for 8 weeks. Oxidative stress markers, prooxidant/antioxidant response, and citrate synthase enzyme activities were assessed in the |i|gastrocnemius|/i|, in the |i|plantaris|/i|, and in the |i|soleus|/i| muscles.

Reasons for performing study: Excessive sweat loss during endurance exercise may lead to electrolyte disturbances and previous research suggests dietary factors may affect hydration status. While investigating the effect of dietary fibre type on hydration status, sweat samples were collected which allowed for the evaluation of sweat composition in horses consuming forage-based, low sodium (Na) rations.. Objective: To investigate sweat composition in Arabian horses performing endurance type exercise while fed forage-based, rations low in Na.. Methods: Six 2-year-old Arabian horses were fed, according to a replicated 3 × 3 Latin square, either grass hay (G), 50:50 grass hay:alfalfa hay (GA), or 50:50 grass hay: chopped fibres (GM) without any additional electrolyte supplementation. After 14 days on each diet, horses performed a 60 km treadmill exercise test. Sweat was collected from sealed pouches on the dorsal thorax after each of four 15 km exercise bouts.. Results: Intake (g/day) of Na (2.5 ± ...
Massoud Arab, A., Salavati, M., Ebrahimi, I., Ebrahim Mousavi, M.. The objective of this study was to describe the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of five clinical tests used to measure trunk muscle endurance in low back pain. A convenience sample of 200 subjects were categorized into four groups: men without low back pain, women without low back pain, men with low back pain and women with low back pain. Five clinical static endurance tests of trunk muscles such as: Sorensen test, prone isometric chest raise test, prone double straight-leg raise test, supine isometric chest raise test and supine double straight-leg raise test were measured in each group. The authors concluded that the prone double straight-leg raise test has more sensitivity, specificity and predictive value in low back pain than other tests and could be used as a useful clinical method for testing the spinal muscle endurance to predict the probability of the ...
Ingestion of creatine (Cr) and glycerol (Gly) has been reported to be an effective method in expanding water compartments within the human body, attenuating the rise in heart rate (HR) and core temperature (Tcore) during exercise in the heat. Despite these positive effects, a substantial water retention could potentially impair endurance performance through increasing body mass (BM) and consequently impacting negatively on running economy (RE). The objective of the present study was to investigate the effects of a combined Cr and Gly supplementation on thermoregulatory and cardiovascular responses and RE during running for 30 min at speed corresponding to 60% of maximal oxygen uptake in hot and cool conditions. Cr·H2O (11.4 g), Gly (1 g·kg-1 BM) and Glucose polymer (75 g) were administered twice daily to 15 male endurance runners during a 7-day period.
Purpose. The aim of the study was to compare myoelectric manifestation in neck muscle endurance and fatigue characteristics during sub-maximal isometric endurance test in patients with cervical radiculopathy and asymptomatic subjects. An additional aim was to explore associations between primary neck muscle endurance, myoelectric fatigability, and self-rated levels of fatigue, pain and subjective health measurements in patients with cervical radiculopathy.. Methods. Muscle fatigue in the ventral and dorsal neck muscles was assessed in patients with cervical radiculopathy and in an asymptomatic group during an isometric neck muscle endurance test in prone and supine. 46 patients and 34 asymptomatic subjects participated.

Maximal oxygen uptake and maximal treadmill times were also increased in all groups. The V̇O(2max) of the placebo increased 18.4%. While that of the atenolol group increased 19.4%, the propranolol group went up 17.0%. After training the maximal heart rate did not change in the placebo group, while ...
Background. Exercise intolerance is one of the most devastating consequences of chronic obstructive pulmonary disease (COPD). Abnormalities in peripheral muscle function such as weakness and reduction in oxidative enzyme activities are commonly found in these patients and may contribute to exercise intolerance.To evaluate whether a systemic weightlifting exercise may improve exercise capacity better than endurance training, or a combined training is more effective, the investigators compared three different training regimens, endurance training alone, systemic weightlifting training alone or a combination of both endurance and weightlifting training.. Methods.36 patients with stable COPD will be evaluated before and after a 4 month training program. Each evaluation include a stepwise exercise test on an ergocycle up to the individual maximal capacity during which minute ventilation (VE), oxygen consumption (VO2), carbon dioxide production (VCO2), and arterial lactic acid concentration will be ...
The aim of the study was to examine the lower extremity biomechanics of the stance phase of sprint and endurance athletes, performing maximum velocity sprint runs. The overall purpose of the study was to assist the development of coaching techniques used in the training of endurance and sprint athletes. Twelve specifically trained participants (six sprint & six endurance athletes) were recruited for the study. The participants were asked to run at maximum velocity over a 50m distance for three successful trials. A motion analysis system was used to track all kinematic data from anatomical landmarks identified on the body (MTP, heel, ankle, knee, hip and shoulder joint centres) to form an animated segmental linked system-stick image tracking each trial. A force plate was synchronised with the motion analysis system to obtain kinetic data from a single ground contact. Sprint athletes achieved an 18% increase in horizontal velocity compared to endurance athletes. Differences in stride (lengths, ...
Interestingly, total RNA (i.e., ribosome density) was 2.3-fold greater in O-WD/SED versus O-WD/EX rats (p = 0.003) despite levels of upstream binding factor protein, RNA polymerase I protein and pre-45S rRNA being greater in O-WD/EX rats. Ribophagy (USP10 and G3BP1) and TRAMP-exosome rRNA degradation pathway (EXOSC10 and SKIV2L2) proteins were assayed to determine if these pathways were involved with lower ribosome density in O-WD/EX rats. While USP10 was higher in O-CON versus O-WD/SED and O-WD/EX rats (p < 0.001 and p < 0.001, respectively), G3BP1, EXOSC10 and SKIV2L2 did not differ between groups. Nop56 and Ncl mRNAs, ribosome assembly markers, were highest in O-WD/EX rats. However, Fbl mRNA and 28S rRNA, downstream ribosome processing markers, were lowest in O-WD/EX rats. Collectively these data suggest that, in WD-fed rats, endurance training increases select skeletal muscle ribosome biogenesis markers. However, endurance training may reduce muscle ribosome density by interfering with rRNA ...

AU - Vollaard, Niels B.J.. PY - 2018/1/2. Y1 - 2018/1/2. N2 - Objectives: Exercise is an important part of disease management in patients with non-alcoholic fatty liver disease (NAFLD), but adherence to current exercise recommendations is poor. Novel low-volume sprint interval training (SIT) protocols with total training time commitments of ≤30 min per week have been shown to improve cardiometabolic risk and functional capacity in healthy sedentary participants, but the efficacy of such protocols in the management of NAFLD remains unknown. The aim of the present study was to examine whether a low-volume SIT protocol can be used to improve liver function, insulin resistance, body composition, physical fitness, cognitive function and general well-being in patients with NAFLD. Methods: In the present study, 7 men and ...
Beta alanine is an amino acid which increases carnosine in the muscles which is needed to regulate Ph as too much acid results in muscle fatigue. Research shows that it reduces fatigue thereby improving performance, endurance and strength as well as improving aerobic activity and lean body mass. Studies have shown that beta-alanine supplements increase muscle carnosine concentrations by 58% in four weeks and 80% in 10 weeks.. L-Glutamine accounts for more than 60% of the free amino acid pool however, there is evidence that our body cannot produce enough glutamine during times of stress, as occurs during intense exercise. Endurance athletes can often suffer low glutamine levels results in muscle breakdown, diminished immune function and reduced performance. Supplementing glutamine can decrease protein degradation, exercise induced muscle damage and improve performance in endurance sports. It is recommended that endurance athletes supplement 6-8grams of glutamine pre-training, 0.5grams an hour ...

In 28 male Caucasian nonprofessional ultracyclists, we investigated whether anthropometry or training volume had an influence on race speed in the 600 km at the Swiss Cycling Marathon 2007. Anthropometric parameters (age, body mass, body height, skinfold thicknesses) were determined before the race to calculate body mass index and percent body fat. In addition, participants, using a training diary, recorded their training volume in hours and kilometers in the 3 months before the race. The influence of anthropometry and training volume on speed in the race as the dependent variable was investigated in a multiple linear regression model. Anthropometry showed a moderate association with speed in the race (r2 = .178, p , .05), whereas training volume showed no association (r2 = .000, p , .05). We concluded that anthropometry had a greater influence on race performance than training volume in recreational ultraendurance cyclists. ...

Where else, if not from Germany, The Land of Beer and Weißwurst as it is falsely perceived by the average foreign Oktoberfest visitor, could the data for a study on the ergogenic effects of nonalcoholic beer originate from? In their recently published paper Johannes Scherr and his colleageas from the Department of Prevention and Sports Medicine at the Klinikum rechts der Isar of the Univerisity of Munich report that a forntload + post-supplementation strategy (3 weeks before, 2 weeks after) with 1-1.5l/day of Erdinger Weißbräu Alkoholfrei led to statistically significant reductions in post-race total blood leukocyte counts (-9%) and interleukin-6 (-24%) and 66% lower incidence of upper-respiratory tract infections in the 58 beer-drinking subjects (age: 36-51y), when compared to their 63 peers(age:35-49y) who received an isocaloric control beverage, which differed from the beer only in terms of its polyphenol content (Scherr. 2012 ...

It has been demonstrated that skeletal muscle adaptions, including muscle fibers transition, angiogenesis, and mitochondrial biogenesis are involved in the regular exercise-induced improvement of endurance capacity and metabolic status. Herein, we investigated the effects of pterostilbene (PST) supplementation on skeletal muscle adaptations to exercise training in rats. Six-week-old male Sprague Dawley rats were randomly divided into a sedentary control group (Sed), an exercise training group (Ex), and exercise training combined with 50 mg/kg PST (Ex + PST) treatment group. After 4 weeks of intervention, an exhaustive running test was performed, and muscle fiber type transformation, angiogenesis, and mitochondrial content in the soleus muscle were measured. Additionally, the effects of PST on muscle fiber transformation, paracrine regulation of angiogenesis, and mitochondrial function were tested in vitro using C2C12 myotubes. In vivo study showed that exercise training resulted in significant increases
Incorporating laughter into a physical activity program could improve older adults mental health, aerobic endurance and confidence in their ability to exercise, a study has found.. In the study, older adults participated in a moderate-intensity group exercise program called LaughActive that incorporates playful simulated laughter - self-initiated as bodily exercise - into a strength, balance and flexibility workout. The findings showed that simulated laughter can be an ideal way for older adults with functional or cognitive impairment. Significant improvements were also found among participants in mental health, aerobic endurance and outcome expectations for exercise. Further, 96.2 per cent participants found laughter to be an enjoyable addition to a traditional exercise program, 88.9 per cent said laughter helped make exercise more accessible and 88.9 per cent reported the program enhanced their motivation to participate in other exercise classes or activities. The combination of laughter ...

Regular physical activity is the most effective non-pharmacological strategy to lower heart rate both at rest and during submaximal physical work. We have previously shown that endurance training-induced changes in heart rate are heritable (h2=0.34). However, few genes associated with heart rate training responses have been identified. The purpose of this study was to perform a genome-wide association study (GWAS) to uncover DNA sequence variants associated with submaximal exercise heart rate training responses in the HERITAGE Family Study. Heart rate was measured during steady-state exercise at 50 Watts (HR50) on two separate days both before and after a 20-week endurance training program in 473 white subjects from 99 families. Illumina HumanCNV370-Quad v3.0 BeadChips were genotyped using Illumina BeadStation 500GX platform. After quality control procedures, 320,000 single-nucleotide polymorphisms (SNPs) were available for the GWAS analyses. Associations between HR50 training response (ΔHR50) ...

Is it possible to adapt simultaneously to strength training and endurance training? Considerable research has been undertaken in an attempt to answer this question. While there is a preponderance of evidence that suggests that training on endurance compromises strength development, particularly when the same body part is involved, some studies have not found an interference effect on strength development as a result of endurance training. The variation between the many studies however may be a result of differences in study design, duration of study, pre-test fitness of subjects, the mode and intensity of training, and strength assessment procedures (Leveritt et al. 2003).. The first study to discuss the interference effect of endurance training on strength development was by Hickson (1980). In this study subjects were assigned to one of three groups: training on strength and endurance simultaneously (SE group), training on strength only (S group) or training on endurance only (E group).
