Effect of the electrostimulation during the tapering period compared to the exponential taper on anaerobic performances and rating of perceived exertion

Abstract

Summary Objective The purpose of the present study was to assess the effect of exponential taper and electrostimulation training during two weeks of tapering on anaerobic performances after resistance training program. Methods Twenty-eight healthy male (age: 17.7 ± 0.8 years; height: 187.1 ± 3.9 cm; weight: 76.7 ± 6.6 kg, and body mass index: 21.9 ± 1.6 kg⋅m−2) were divided into three groups: control group, exponential taper group and electrostimulation taper group. During resistance period, all groups followed the same training program during 5 weeks (3 sets × 10 repetitions with 2 min of rest; intensity = 10 repetition maximum). At the taper period, control group continued with the same program. In contrast, both exponential groups had a diminution of training volume. Participants were tested in three periods (i.e., before and after the resistance training and after the tapering phase) for the determination of maximum repetition, squat jump and countermovement jump. Subjects answered to questionnaire of rating of perceived exertion after every training session. Results Resistance training showed a significant improvement of muscle strength and power in the three groups. However, in response to tapering phase, vertical jump performances and maximum repetition increased significantly only in both tapering groups. No significant difference was showed between exponential taper group and electrostimulation taper group after two weeks of taper.
