This book was released on 2012-03 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2011 in the subject Biology - Cytology, grade: C, University of Glasgow (Institute of Cardiovascular and Medical Sciences), course: MRes Biomedical Sciences, language: English, abstract: The skeletal muscle is an integral part of our system. It not only acts as the storage reservoir of amino acids, but also serves as the site for protein synthesis and protein breakdown [36]. The rate of protein synthesis needs to exceed protein degradation to achieve muscle hypertrophy [18, 24]. The timing of protein intake, type and quantity play a significant role in achieving optimal outcomes when applied to resistance exercise [36]. Research has been going on since the past decade demonstrating the role of nutritional supplements like whey protein, soy, branched-chain amino acids (BCAAs, especially leucine) and creatine on protein synthesis before, during and after a bout of resistance exercise through careful investigations into intracellular signalling pathways like the mammalian target of rapamycin (mTOR) and its downstream targets-ribosomal protein S6 (kinase-1) and 4E binding protein (4E-BP1) [7, 18]. Intracellular signalling, amongst other variables, involves three essential components-abundant ATP in muscle for providing energy, insulin signalling and leucine (figure 1) [36, 37]. mTOR, regarded as the "key regulator" of translation comprises mTORC1 and mTORC2 [36]. mTORC1 plays a significant role in promoting muscular hypertrophy via phosphorylation of S6K1 and 4E-BP1 which prevent binding of the eukaryotic initiation factor (eIF) 4E to 4E-BP1 allowing a complex formation with eIF4G (eIF4E-eIF4G) thus enhancing protein synthesis [5, 34]. This report highlights how whey proteins and BCAA (leucine) affect muscle protein synthesis via intracellular signalling pathways thereby contributing significant effects on muscular hypertrophy.

Download or read book The Role of Protein and Amino Acids in Sustaining and Enhancing Performance written by Institute of Medicine and published by National Academies Press. 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.

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.
