Association of mitochondrial oxidative capacity with physical fitness in ageing: the Baltimore longitudinal study of ageing.

Background In younger individuals, fitness is mostly influenced by muscle mitochondrial oxidative phosphorylation (OxPhos) and cardiac output. However, compared with younger individuals, various impairments may also negatively affect fitness in older adults. Objective To investigate the relationship...
