Tirante Musculador® e meio agachamento: sessão de treinamento de força rápida e sua recuperação

Abstract

The aim was to describe and compare a strength training session in the Tirante Musculador® (TM) with a session in the half squat guided (HS), and also the recovery of participants after the execution of both exercises. 19 volunteers of both sexes (10 female and 9 male), with an average age of 17.4 ± 1.5 years (58.7 ± 9.2 kg of body weight; 170.1 ± 9.1 cm stature; 35.1 ± 11.5 mm in the sum of skinfolds), track and field athletes. Ten meetings were held. On the meeting 1 was randomized to the choice of which exercise would be did first, anthropometric evaluation and the test of 1RM of exercise chosen were carried out, and after 72 hours performed four series of eight movements with 80% of 1RM (meeting 2), and every 24 hours did tests for the evaluation of recovery, until to 72 hours (3, 4 and 5 meetings) and for the second exercise the entire procedure was repeated (6 to 10 meetings). During the 2 and 7 meetings were captured electromyographic sings (EMG) of muscle which Vastus lateralis (VL), Rectus Femoris (RF) and Vastus medialis (VM) and measure the execution speed of the movements, to the meetings of 3 to 5 and 8 to 10, were collect total quality recovery scale measures (TRQ), delayed onset muscle soreness (DOMS), maximum isometric voluntary contraction, (MIVC), EMG of the VL during the MIVC and a counter movement jump (CMJ). There was no difference in the EMG between the two exercises (p > 0.05), however, the RF features a large effect size (1.07), suggesting greater participation on implementation of TM than in HS, finding no difference also between the power generated in the TM and HS (p > 0.05). When compared to TM recovery with the HS did not find a difference to any of the variables (p > 0.05). Thus, we conclude that both the TM, as HS are good exercises to develop the power, and in this protocol type recover quickly. The TM presents a certain advantage when compared with the HS due to absolute external loads are smaller than in the HS and submit internal responses alike. Qualitatively, the effect of the applied load seems to last longer in TM than in MA, but both happen on the same magnitude, therefore, it is necessary that new studies be conducted in chronic way in order to understand the possible effects.
