To document the initial response of velocity-specific isokinetic training, two groups of nine males (19-35 years) performed either low velocity (3 sets of 10 reps at 0.52 rad/s, SVT) or fast velocity (3 sets of 10 reps at 4.71 rad/s, FVT) training for 2 days. Knee extension peak torque was measured at 0.52, 2.62, and.4.71 rad/s on three separate days. Test 1 was given on day 1 and test 2 on day 4. Training protocols were performed on days 7 and 9, and test 3 was performed on day 11. Neither group showed a significant change (p>0.05) in peak torque between test 1 and test 2 for any. of the three test velocities. For test 3, SVT showed no change in torque at any speed, but FVT showed a significant (p<0.05) 22.1+/-10.0% increase in mean peak torque at 4.71 rad/s. Since FVT's magnitude of increase in peak torque was similar to that reported by other investigators using 6-10 week training protocols, it is suggested that neural adaptations have a major role in torque production improvements that are specific to a single fast training velocity.
