High-intensity exercise may help older adults reverse certain aspects of the “cellular” aging process, a new study suggests.
It’s no secret that regular exercise is healthy for young and old alike. But researchers said the new findings point to particular benefits from “high-intensity interval training” for older adults. That’s the type of workout that combines brief bursts of vigorous exercise with periods of moderate activity: A person might, for example, go all-out on a stationary bike for a few minutes, ease up for the next few, and then start again.
In this study, older adults who performed that type of exercise showed greater changes at the cellular level, compared to those who worked out more moderately. Specifically, interval training gave a bigger boost to mitochondrial function in the muscle. Mitochondria are the “powerhouses” within body cells that break down nutrients to be used for energy. The training also revved up activity in more genes related to mitochondrial function and muscle growth.
Participating in physical activities and exercise on a regular basis can provide many benefits to younger and older adults alike. High intensity exercise may additionally benefit middle-aged people because it can help reverse the body’s cellular aging process.
