Ten-year longitudinal changes in muscle power, force, and velocity in young, middle-aged, and older adults.

ABSTRACT:

Background

Maximum muscle power (P_max ) is a biomarker of physical performance in all ages. No longitudinal studies have assessed the effects of aging on P_max obtained from the torque-velocity (T-V) relationship, which should be considered the 'gold standard'. This study evaluated the longitudinal changes in the T-V relationship and P_max of the knee-extensor muscles in young, middle-aged, and older adults after 10 years of follow-up.

Methods

Four hundred eighty-nine subjects (311 men and 178 women; aged 19-68 years) were tested at baseline and after a 10-year follow-up. Anthropometric data, daily protein intake, physical activity level (PAL), and knee-extension muscle function (isometric, isokinetic, and isotonic) were evaluated. A novel hybr
