Abstract:
Important advances have been made in the understanding of the regulation of protein metabolism, which are of relevance to those interested in maximizing muscle performance in sport and aging. The use of 24 h amino acid infusion studies, the development of methods to measure skeletal muscle fractional breakdown rate and the fractional synthetic rate of specific proteins have and will continue to enhance our understanding of protein metabolism in exercise. Recent studies have demonstrated potentially beneficial effects upon protein metabolism by altering the composition and timing of nutrient delivery. Exercise and nutritional interventions may positively influence the negative effects of aging upon protein metabolism.

Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
