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.
