Inactivity, age, and exercise: single-muscle fiber power generation.
We examined the effects of mild therapeutic exercise during a period of inactivity on size and contractile functions of myosin heavy chain (MHC) type I (n = 204) and type II (n = 419) single fibers from the medial gastrocnemius in three age groups. Young adult (5-12 mo), middle-aged (24-31 mo), and old (32-37 mo) F344BNF1 rats were assigned to one of three groups: weight-bearing control, non-we...
متن کاملSkeletal muscle loss: cachexia, sarcopenia, and inactivity.
Loss of skeletal muscle mass occurs during aging (sarcopenia), disease (cachexia), or inactivity (atrophy). This article contrasts and compares the metabolic causes of loss of muscle resulting from these conditions. An understanding of the underlying causes of muscle loss is critical for the development of strategies and therapies to preserve muscle mass and function. Loss of skeletal muscle pr...
متن کاملRegulation of skeletal muscle fat oxidation during exercise in humans.
Fat and carbohydrate are the major energy substrates during aerobic exercise in well-fed humans. The regulation of fat metabolism during exercise has not been as thoroughly studied as carbohydrate metabolism, especially in human skeletal muscle. Traditionally, it was believed that the regulation of skeletal muscle fat metabolism was mainly at the level of the delivery of free fatty acids to the...
متن کاملAge-Associated Changes in Skeletal Muscle Regeneration: Effect of Exercise
Aim of the present short review is to provide a comprehensive update on age-associated skeletal muscle damage, regeneration, and effect of endurance and resistance type of exercise training on muscle regeneration. Decrease in muscle quantity and quality leads to disability in the aging population. The degradation rate of muscle proteins during aging increased about two times, and muscle strengt...
متن کاملThe Impact of Exercise on Statin-Associated Skeletal Muscle Myopathy
HMG-CoA reductase inhibitors (statins) are the most effective pharmacological means of reducing cardiovascular disease risk. The most common side effect of statin use is skeletal muscle myopathy, which may be exacerbated by exercise. Hypercholesterolemia and training status are factors that are rarely considered in the progression of myopathy. The purpose of this study was to determine the exte...
