Comparison of weak leg knee extensor power (A), strong leg knee extensor power (B), and power asymmetry (C) between older adults with symmetrical (≤ 15%) and asymmetrical (> 15%) knee extensor power across a range of isokinetic contraction velocities.
a = different between asymmetrical and symmetrical groups, p < 0.05
b = different from 60 deg s−1 isokinetic test velocity, p < 0.05
c = different from 180 deg s−1 isokinetic test velocity, p < 0.05
