Background and Purpose:
Physical function is shown to decline with age. However, how long-term strength training may attenuate the age-related limitation in functional tasks with various force demands is unclear.
Methods:
In a cross-sectional study, we assessed maximal muscle strength, initial and late phase rate of force development (RFD), as well as 4 tests of functional performance in 11 (mean, 71 years; standard deviation [SD], 4 years) strength-trained master athletes (MAs), 11 (mean, 73 years; SD, 6 years) recreationally active older adults (AEs), 10 (mean, 71 years; SD, 4 years) sedentary older adults (SOAs), and 9 (mean, 22 years; SD, 2 years) moderately active young controls. Functional performance was divided into 2 categories: more force-demanding (chair-rising ability and stair-climbing power) and less force-demanding (habitual walking speed and 1-leg standing) tasks.
Results:
MA exhibited 75%, 45%, and 26% higher leg press maximal strength compared with SOA, AE, and young, respectively (P
