Abstract
Isokinetic concentric and isometric contractions of the wrist flexors and extensors were recorded from 40 young males using a Cybex II+ isokinetic exercise system using handgrips of 4 cm and 8∼cm diameter: the isokinetic recordings were obtained at velocities of movement of 45°/s, 90°/s and 180°/s. For both muscle groups peak torque and work done both decreased with increased velocity of contraction, however average power increased. The wrist flexors generated significantly(P < 0.01) greater peak torque, work and average power than the extensors, with the extensor/flexor ratio for peak torque being 0.57. No differences were observed between the dominant and non-dominant wrist, or between the size of handgrip used.
