This book was released on 2017 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: The purpose of this study was to determine if a creatine supplement prevents the decrease in performance while consuming a low carbohydrate (CHO) diet during high-intensity exercise. Compared to the placebo group where the low CHO diet was expected to result in reduced exercise tolerance, it was hypothesized that creatine supplementation would offset the adverse side effects of a low CHO diet, as demonstrated by a similar or improved exercise capacity. Methods: Twenty healthy subjects (8 males, 12 females; 27 ± 7 yrs, ±SD) were randomly assigned to a low CHO plus creatine monohydrate supplement (L-CHO+Cr), low CHO diet and placebo (LCHO) group, or control (CON). Each subject performed 2 high intensity exercise tolerance tests (HIETT) to fatigue at 90% peak power output (PPO), separated by a 10 days where the subject followed a low CHO diet (

This book was released on 1999 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary creatine (Cr) supplementation is currently a common practice among athletes and U.S. Naval Special Warfare personnel. The ergogenic effect of supplemental Or has been demonstrated under certain well-controlled laboratory conditions, but the evidence supporting Cr use to augment performance under operational or field conditions is equivocal. This investigation was designed to evaluate the effects of dietary Cr supplementation on the performance of military tasks by U.S. Navy Sea Air and Land (SEAL) personnel. SEAL volunteers, ages 23 to 42 years, performed two familiarization time trials and a baseline (control) obstacle course (OC) time trial lasting -2 min. Using a randomized, double-blind protocol, each subject consumed 20 g/d of artificially sweetened Or (n = 12) or polycose placebo (n = 12) for 5 days. Within 24-hr after consuming the final dose, a post-treatment OC time trial was performed. Body composition and total body water was measured before the control and post-treatment OC time trials. Blood lactate levels were measured at 5 and 10 min after completion of the control and post-treatment OC time trials. Treatment effects were assessed by repeated measures ANOVA. Group differences for percent body fat, hydration status, and age were noted after group assignment but were unrelated to Cr supplementation. Five days of Cr supplementation at 20 g/d had no significant effect (p> 0.1) on body composition, total body water, blood lactate, or OC performance time. The small effects on performance seen in some laboratory studies with Cr supplementation do not appear to carry over to field-related tasks conducted in an operational setting.

Download or read book Skeletal Muscle Circulation written by Ronald J. Korthuis and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

This book was released on 2009 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Which of the following will yield the fastest measurable change in performance and/or body composition? (A) changes in training. (B) changes in diet. (C) use of sports supplements. (D) they all work equally well. If you answered 'C,' go to the head of the class. That's right; the proper use of sports supplements can produce changes in minutes (e.g. caffeine), days (e.g. creatine) and weeks (e.g. beta-alanine). Yet we are bombarded by muddled thinking from the mainstream media telling us that 'creatine causes cramps,' 'high protein diets are bad for your kidneys,' 'supplements aren't needed as long as you eat a balanced diet' and other ideas that are void of data. Sports Nutrition & Performance Enhancing Supplements (eds. Abbie Smith-Ryan PhD CSCS*D CISSN and Jose Antonio PhD FNSCA FISSN. Linus Publications) is a focused resource that will give you the latest sports nutrition science, and eradicate the intellectually lazy positions held so dearly by the anti-supplement crowd."--Amazon.

Download or read book The Biology of Exercise written by Michael J. Joyner and published by Perspectives Cshl. This book was released on 2017 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exercise training provokes widespread transformations in the human body, requiring coordinated changes in muscle composition, blood flow, neuronal and hormonal signaling, and metabolism. These changes enhance physical performance, improve mental health, and delay the onset of aging and disease. Understanding the molecular basis of these changes is therefore important for optimizing athletic ability and for developing drugs that elicit therapeutic effects. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine examines the biological basis of exercise from the molecular to the systemic levels. Contributors discuss how transcriptional regulation, cytokine and hormonal signaling, glucose metabolism, epigenetic modifications, microRNA profiles, and mitochondrial and ribosomal functions are altered in response to exercise training, leading to improved skeletal muscle, hippocampal, and cardiovascular function. Cross talk among the pathways underlying tissue-specific and systemic responses to exercise is also considered. The authors also discuss how the understanding of such molecular mechanisms may lead to the development of drugs that mitigate aging and disease. This volume will therefore serve as a vital reference for all involved in the fields of sports science and medicine, as well as anyone seeking to understand the molecular mechanisms by which exercise promotes whole-body health.
