Power output is now considered one of, if not the, most highly regarded metric when predicting overall longevity, healthspan and independence. It is well understood that the greater one’s absolute and relative power output, the greater the chances of them continuing to live and independent, active life. Of course, extraneous variables may alter this outcome. For example, one may score extremely well on a single squat performance demonstrating elevated rate of force development (power) but they may be limited to one repetition due to a lung condition that causes shortness of breath. One limited to a single repetition will of course struggle with activities of daily living as many are not simple one movement tasks.
