The purpose of this study was to examine age-related differences in muscle performance in women divided into young (YW, 20-39 years, = 29) middle-aged (MAW, 40-59 years, = 33), and older (OW, ≥60 years, = 40) age groups.
Methods: Hand grip strength, vertical jump performance, and knee extensor (KE) strength (0 deg/s, 60 deg/s, and 240 deg/s), speed of movement (SoM; at 1 Nm, 20%, 40%, and 60% isometric strength), and endurance (30-repetition test at 60 degs/s and 240 deg/s) were assessed. Computed tomography-acquired muscle cross-sectional area (mCSA) was measured and included to determine specific strength (KE strength/mCSA). Read More
