To compare the influence of slow and fast contraction velocities in the total volume of load lifted in a resistance training bout with free weights exercises for upper limbs, and analyze the recovery time of the maximum muscle strength post-exercise in resistance-trained men. Methods. Sixteen young men, who were experienced in resistance training were randomly divided into two groups: fast contraction velocity (FCV - n = 8) and slow contraction velocity (SCV - n = 8). Both groups performed bench press and incline bench press exercises (free weights) with 4 sets of 12 repetitions maximum. There was a 50 seconds rest interval between each set, and 2 minutes interval between the exercises. The contraction velocity was 6 seconds for the SCV group and 1.5 seconds for the FCV group. The total volume of load was recorded during the exercise bout, and the one repetition maximum (1RM) was evaluated before (baseline) and for 96 hours after exercise to measure the neuromuscular function. Results. The results demonstrated that the FCV group provide a higher (p < 0.05) volume of load lifted during the exercise bout, and had a significant decline (p < 0.05) in the neuromuscular performance post-exercise, when compared to the SCV group. Conclusion. These data suggest that besides the contraction velocity, the total volume of load lifted determines the decline of neuromuscular function post-exercise in resistance-trained men. ER -
