This editorial note scrutinizes an important clinical opinion regarding the role of mitochondria in generating differing strength and endurance capabilities in elderly vs. young people. The submaximal effort against resistance, as well as endurance effort differs between young vs. elderly people. This is usually explained by neurophysiological differences, but this editorial note presents a hypothesis regarding the aging mitochondria. Mitochondria in young people obtain all the necessary physical and metabolic properties that are needed and acquired throughout adulthood; yet, mitochondria in elderly people undergo many changes.
