Popis: Summary Objective The purpose of this study was to investigate the effects of low-intensity strength training with vascular occlusion on specific parameters of neural drive using amplitude and spectral analysis of surface electromyography. Equipment and methods Twenty individuals were assigned to one of two groups (low-intensity strength training with or without vascular occlusion). The first group performed three sets of knee extension exercises until failure, with a 90 seconds interval between sets, while the second group performed three sets of the mean repetitions of the first group. Both groups performed the exercises with the load set at 20% of estimated 1 maximal repetition. To assess electromyographic parameters, sessions 1, 7 and 12 were evaluated, specifically from the first to third repetitions and the 3 final repetitions. One maximal repetition was measured in the same collection times. Results Our findings demonstrated that low-intensity strength training with vascular occlusion improved muscular strength; however, it did not affect the neural drive, since there were no differences in the investigated parameters between sessions. Conclusion Low-intensity strength training with vascular occlusion is effective for producing muscular strength; however, it is not indicated for increases in neural activity.
