Skeletal muscle mitochondrial energetics are associated with maximal aerobic capacity and walking speed in older adults

Lower ambulatory performance with aging may be related to a reduced oxidative capacity within skeletal muscle. This study examined the associations between skeletal muscle mitochondrial capacity and efficiency with walking performance in a group of older adults. Thirty-seven older adults (mean age 7...
