Aging and aging-related declines in physical activity are associated with physical and metabolic impairments. Skeletal muscle capillarization is reduced in sedentary older adults, may contribute to impairments in skeletal muscle, and is modifiable by exercise training. This article examines the hypothesis that preservation of skeletal muscle capillarization is essential to maintain metabolism, fitness and function with aging.
