n3 PUFA and Muscle-disuse Atrophy in Young Women
Effects of n3 PUFA Supplementation on the Attenuation of Muscle Disuse Atrophy in Young Women
研究概览
详细说明
Biological aging is associated with the loss of skeletal muscle mass and strength resulting in compromised metabolic function and mobility. Throughout life, individuals will also experience periods of reduced physical activity/muscle disuse that independently lower muscle mass and strength accelerating the aging process. The losses in muscle mass with aging and disuse are underpinned by feeding-induced declines in rates of muscle protein synthesis. Thus, strategies to enhance muscle protein synthesis could have clinical implications for those who wish to maintain metabolic health and function during times of muscle disuse.
Supplementation with n3 PUFA-enriched fish oil has been shown to potentiate rates of muscle protein synthesis in response to simulated feeding in both younger and older adults. Fish oil supplementation also has been efficacious in enhancing skeletal muscle strength during a period of resistance exercise training. However, no study has examined the impact of fish oil supplementation to enhance muscle protein synthesis and offset declines in muscle mass/strength during a period of immobilization.
