Abstract:
L-citrulline (L-Cit) has emerged as a potential supplement to enhance muscle performance and protein metabolism. This review summarizes evidence from rodent and human studies, highlighting its effects on muscle function, protein synthesis, and underlying mechanisms. Key areas for future research include supplementation strategies, transport and metabolism pathways, mitochondrial function, and the interaction between L-Cit, gut microbiota, and muscle health, offering insights for nutritional interventions targeting aging and sarcopenia.

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...
