Abstract

Although the effects of short-term isokinetic resistance training have been shown to increase peak torque (PT) across the velocity spectrum only in the leg extensors, the minimum number of training sessions needed to increase forearm flexion PT is unknown. This study examined the effects of three concentric isokinetic training sessions on PT for the forearm flexors at 4 velocities (maximal voluntary isometric contraction (MVIC), 60, 180, and 300°·s -1). Ten adult females (mean ± SD age = 21.2 ± 0.8 yrs; body weight = 65 ± 9.4 kg; height = 170.0 ± 6.2 cm) completed two pretests and a posttest that included maximal muscle unilateral isometric and concentric isokinetic forearm flexion of the non-dominant arm at the 4 velocities. During the 4th through 6th visits the subjects performed 5 sets of 10 maximal isokinetic concentric forearm flexion (non-dominant arm) repetitions at 60°·s -1. The results of a 3 x 4 [time (pretest 1, pretest 2, and posttest) x velocity (MVIC, 60, 180, 300°·s -1)] repeated measures ANOVA indicated there was no significant time x velocity interaction (P>0.05) or main effect for time. There were, however, significant decreases in PT at each velocity. The present findings indicated that three sessions of concentric isokinetic training for the forearm flexors were not sufficient to elicit increases in PT across a velocity spectrum (MVIC to 300°·s -1) in females.
