Effects of isokinetic velocity spectrum exercise on torque production

The purpose of this study was to assess the effect of variation in the order of four different isokinetic velocity exercise protocols on muscle torque production. Twenty‐two subjects were randomly assigned to four exercise trials, each containing an isokinetic exercise session involving the dominant knee extensor and flexor. Each trial consisted of performing two sets of 10 repetitions at velocities of 30°, 90°, 150°, and 210° per second in varying order. Peak torque (Nm), average peak torque (Nm), and average torque (Nm) were used to make comparisons between the four protocols. Univariate analysis showed no significant effect (p >0.05) of varying the order of isokinetic velocity of muscle contraction in the four protocols described for any of the three torque measurements. It was concluded that varying the pattern of isokinetic velocity at which a specific torque is developed does not interfere with general or specific torque at a particular velocity of contraction.
