摘要：

This investigation examined differences in functional sit-to-stand power/velocity between cohorts of adults aged 18-97 years. This study included 264 healthy adults classified into four cohorts (18-40, Cl; 60-69, C2; 70-79, C2; >=.80, C4). Participants completed the sit-to-stand task five times. Power and velocity were measured via the [ENDO power analyzer. Absolute average power was maintained from Cl C3, but decreased (p<.01) in C4. Absolute peak power decreased between Cl C2 (p <.01), was similar between C2 C3, and decreased in C4 (p <.01). Relative (to body weight) average and peak power decreased between Cl C2 (p <.01), was similar between C2 C3, and decreased in C4 (p <.01). Average velocity was similar between C1 and C2, but decreased in C3 (p <.01) and C4 (p <.01), respectively. Peak velocity was significantly different between all cohorts (p <.01). Declines in functional power may plateau during the seventh and eighth decades, accelerating after 80 years.
