Book Description
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.

Simulated Microgravity and Radiation Exposure Effects on the Regulation of Skeletal Muscle Protein Synthesis

Book Description
Long duration spaceflight missions out of lower earth orbit, back to the lunar surface, or possibly to Mars highlight the importance of preserving muscle mass and function. Muscle atrophy occurs within days of exposure to microgravity and prevailing thought is that a primary mechanism for muscle atrophy is a reduction in skeletal muscle protein synthesis. This dissertation examines the ability of skeletal muscle to recover muscle protein synthesis with slight perturbation, such as ambulatory reloading during disuse as well as partial loading, similar to body mass seen on the moon or Mars. We use traditional precursor-product labeling to measure protein synthesis, but use a relatively novel tracer, deuterium oxide, in order to make cumulative measures of protein synthesis over 24 h. The overarching goal of this dissertation is to define the response of skeletal muscle protein synthesis to different loading parameters in order to better understand the contribution of protein synthesis to skeletal muscle mass during disuse. In the first study, we demonstrate that muscle atrophy during 5 days of hindlimb unloading is in part due to a decrease in protein synthesis. We also highlight the ability of skeletal muscle to adapt by allowing two 1 h ambulatory reloading sessions on days 2 and 4. Although this countermeasure is able to rescue protein synthesis in soleus and gastrocnemius, it is unable attenuate any losses in muscle mass. In the second study, we compare partial weight loading to traditional hindlimb unloading. Weight bearing of 1/3 or 1/6 body weight is able to attenuate losses in muscle mass seen with unloading. Protein synthesis is maintained after 21 days of the experimental protocol, suggesting that protein synthesis is responsive to load and is likely not the only mechanism for determining muscle mass. In the final study, the effects of
