Minimal power required to ascend a flight of stairs versus actual power measured with body‐fixed sensors in adults aged 19–85 years

Lien Meulemans, Jan Seghers, Annabel Hoorelbeke, Tinne Van Dijck, more

Scandinavian Journal of Medicine & Science in Sports > 34 > 3 > n/a - n/a

A good stair‐climbing (SC) ability is crucial for independent living in older adults. A simple formula that estimates the mean power needed to ascend a flight of stairs in a predetermined time (i.e., total ascent duration) is easy to implement in practice, but lacks information on actual power values generated per step. The latter is possible with body‐fixed sensors. This study aimed at comparing...
