Resumo
Background: We aimed to investigate the effect of rest interval, between successive contractions, on muscular fatigue.Methods: Eighteen subjects performed elbow flexion and extension (30 repetitions) on an isokinetic dynamometer with 80 degrees of range of motion. The flexion velocity was 120 degrees/s, while for elbow extension we used 5 different velocities (30, 75, 120, 240, 360 degrees/s), producing 5 different rest intervals (2.89, 1.28, 0.85, 0.57 and 0.54 s).Results: We observed that when the rest interval was 2.89 s there was a reduction in fatigue. on the other hand, when the rest interval was 0.54 s the fatigue was increased.Conclusions: When the resting time was lower (0.54 s) the decline of work in the flexor muscle group was higher compared with different rest interval duration.
