Description

Antti Löppönen and co-authors ask in this 2026 study whether the speed of standing up from a chair fades across the day in older adults, and what that fade means. They fitted thigh sensors to 479 people aged seventy-five, eighty, or eighty-five, recording sit-to-stand moves for up to a week. Groups were split by self-rated walking fatigue, tested fatigue, and daily function.

Everyone's stand speed dipped late in the day, but the dip ran deeper in the high-fatigue groups from mid-afternoon on. Those with function limits dipped most in the evening hours. The authors propose the evening fade, caught by a wearable, as an early flag for fatigue and decline.
