Acute effects of pre-exhaustion, combined with resistance training, on muscle performance
Keywords: pre-examination; strength training; Muscular hypertrophy.
Introduction: The prior exhaustion of the isolated target muscle, followed by the execution of multiarticular exercises for it, seems effective in obtaining positive effects: muscle fatigue combined with greater recruitment of type II muscle fibers, leading high levels of hypertrophy. and of strength. However, more evidence in the literature is required that the inclusion of pre-exhaustion in force training programs sharply interferes with the performance of the “pre-examined” muscle. Objective: To evaluate and compare the acute effects of two training methods-traditional and pre-exhaustion-in trained men and women. METHODOLOGY: Randomized, 20 trained young people - 10 men and 10 women - will hold two distinct training sessions - separated by 1 week break. In one session, the volunteer will hold 5 free squat series - with 75% of 1RM - until momentary muscle failure; In another session, the volunteer will perform prior exhaustion of the maximum glute through the pelvic elevation and then the free squat; both with 50% of 1RM and performing the same 5 series. The effects of non -uniform muscle thickness of quadriceps and muscle thickness of the maximum gluteus will be evaluated; PSE; late muscle pain; Blood lactate; Time under tension; Total volume of training and recovery after session (QTR). RESULTS: It is speculated that, as a result of the enhancement of activation of type II muscle fibers, the thickness of the pre-examination-maximum glute-should overcome those arising from the force training program performed without the application of this model.
