Changes in isokinetic muscle strength parameters at angular velocity of 180°/s

The changes of the peak torque of knee extensor (A), the peak work of knee extensor (B), the peak torque of knee flexor (C) and the peak work of knee flexor (D) among groups. HE, health education group; ST, strength training group; WBV, whole body vibration group; PT, peak torque; PW, peak power; #, p < 0.017, changed significantly compared with the HE group; &, p < 0.017, changed significantly compared the ST group.
