Angular Velocity Affects Trunk Muscle Strength and EMG Activation during Isokinetic Axial Rotation

Figure 5

The RMS value of each muscle at different velocities in both directions ((a) left rotation; (b) right rotation). Among three primary agonists in each direction, external oblique exhibited the highest RMS value during isokinetic axial rotation. For each primary agonist, the RMS value decreased with the increase of angular velocity. , compared between that at 30°/s and 120°/s.
