S. in Kinesiology) and published by . This book was released on 2016 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skeletal muscle is important for physical activity and regulation of metabolism. Increase or maintenance of muscle mass is pursued by different populations ranging from athletes to people suffering from severe muscular diseases causing muscle atrophy/wasting. In this study, four animal groups were generated: sedentary group (No supplements or exercise) (SED); resistance training (RE) and whey supplements (WP); RE and combo (Carbohydrate and whey) supplements (CP); RE and placebo (DI water) (PLA). Flexor hallucis longus (FHL) muscles were collected after 8 weeks of training. Expression of several key proteins controlling muscle mass and protein turnover were measured in order to compare how different combinations affect muscle growth. It was found that resistance training induced reductions in myostatin protein expression compared with sedentary controls (p

Download or read book Food Components to Enhance Performance written by Institute of Medicine and published by National Academies Press. This book was released on 1994-02-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

Download or read book Effects of Carbohydrate protein Intake During Marathon Running on Post exercise Markers of Muscle Damage and Recovery written by and published by . This book was released on 2011 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The purpose of the present study was to investigate indices of muscle damage and recovery in novice runners following completion of a marathon, and compare responses in these indices when receiving carbohydrate (CHO) or carbohydrate-protein (CHO+Pro) supplementation during the marathon run. Methods: 16 subjects were arranged into matched-pairs based on muscle damage responses; determined by serum kinase (CK) levels following an 18-mile training run. Subjects' perceived ratings of muscle soreness and mental/physical energy/fatigue, maximal isometric force of the leg extensors (MVC), and serum CK were measured on three occasions: prior to the marathon, 24 hours post-marathon and 72 hours post-marathon. During the 26.2-mile marathon run, subjects consumed energy gels (100 kcal/packet) at four-mile intervals throughout the event. Members of each matched-pair were assigned to a CHO (25 g CHO) or CHO+Pro (20 g CHO, 5 g Pro) gel in a randomly counterbalanced design. Results: Significant declines in MVC, and mental energy ratings were observed 24-hours post-marathon, with significant increases in serum CK, muscle soreness, and physical fatigue ratings. These responses were attenuated by 72 hours post-marathon (in comparison to 24-hour levels), but serum CK and perceived muscle soreness remained significantly different from pre-marathon levels. No significant differences were observed between CHO and CHO+Pro treatments for any of the muscle recovery variables studied. Conclusions: Marathon running results in significant impairment in skeletal muscle function, soreness/fatigue, and elevated markers of sarcolemmal damage for at least 72 hours post-event. CHO+Pro ingestion during the marathon does not appear to influence post-marathon muscle recovery in comparison to CHO intake alone.

Download or read book The Effects of an Amino Acid Mixture Beverage on Glucose Tolerance Glycogen Replenishment Muscle Damage and Anaerobic Exercise Performance written by Bei Wang (doctor of kinesiology.) and published by . This book was released on 2011 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent research suggests that amino acids, such as leucine and isoleucine, can improve glucose tolerance in vivo and in vitro animal models by accelerating glucose uptake in peripheral tissues and stimulate glycogen synthesis in vitro in the absence of insulin. Our laboratory recently found that gavaging normal Sprague-Dawley rats with an amino acid mixture, composed of isoleucine, leucine, cystine, methionine, and valine, improved blood glucose response during an oral glucose challenge without an increase in the plasma insulin response. The blood glucose-lowering effect of the amino acid mixture was due to an increase in skeletal muscle glucose uptake. These results suggest that this amino acid supplement acutely improves muscle insulin sensitivity and blood glucose homeostasis. However, the effect of this amino acid mixture on glucose tolerance and muscle glycogen synthesis in humans has not been investigated. Some studies have also shown that daily supplementation or acute ingestion of amino acids may prevent muscle damage that occurs as a result of a prolonged, intense endurance exercise or strength training and therefore improves force production and exercise performance. However, the effects of the addition of an amino acid mixture to carbohydrate supplement on muscle damage after a prolonged endurance exercise, as well as on the subsequent anaerobic exercise performance, have not been characterized. Therefore, in this series of two studies, the effects of an amino acid mixture, composed of isoleucine, leucine, cyctine, methionine, and valine, on glucose tolerance, muscle glycogen resynthesis, muscle damage, and anaerobic exercise performance were investigated. Study 1 demonstrated that our amino acid mixture lowered the glucose response to an OGTT in healthy overweight/obese subjects in an insulin-independent manner. Study 2 demonstrated that both high and low dosages of amino acid mixture were effective in lowering blood glucose response to a carbohydrate bolus in athletes postexercise. High dosage of amino acid mixture was more potent in glucose regulation by providing a higher insulin response and amino acid effect. However, our amino acid mixture had no effects on post exercise muscle glycogen synthesis, exercise-induced muscle damage or subsequent anaerobic performance. Taken together, the results of this research series suggest that an amino acid mixture, composed of isoleucine and 4 additional amino acids, attenuates the glucose response to a glucose bolus in an insulin-independent manner, but does not enhance muscle glycogen restoration following exercise or prevent exercise-induced muscle damage.

This book was released on 1999-09-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a commonly held belief that athletes, particularly body builders, have greater requirements for dietary protein than sedentary individuals. However, the evidence in support of this contention is controversial. This book is the latest in a series of publications designed to inform both civilian and military scientists and personnel about issues related to nutrition and military service. Among the many other stressors they experience, soldiers face unique nutritional demands during combat. Of particular concern is the role that dietary protein might play in controlling muscle mass and strength, response to injury and infection, and cognitive performance. The first part of the book contains the committee's summary of the workshop, responses to the Army's questions, conclusions, and recommendations. The remainder of the book contains papers contributed by speakers at the workshop on such topics as, the effects of aging and hormones on regulation of muscle mass and function, alterations in protein metabolism due to the stress of injury or infection, the role of individual amino acids, the components of proteins, as neurotransmitters, hormones, and modulators of various physiological processes, and the efficacy and safety considerations associated with dietary supplements aimed at enhancing performance.
