Angular Velocity Affects Trunk Muscle Strength and EMG Activation during Isokinetic Axial Rotation
Parameters measured by the dynamometer at three different velocities, including peak torque (a), ratio of peak torque to body weight (b), single maximal repetition work (c), and power (d). Both PT and PT/BW decreased with the increase of angular velocity. Conversely, the peak power increased with the increase of angular velocity in each direction. As for these parameters, significant difference was found between 30°/s and 120°/s. No significant difference was found among different angular velocities in single maximal work. , compared with that at 120°/s.
