Treinamento muscular respiratório em atletas amadores de CrossFit® : série de casos.

Abstract

CrossFit® is high-intensity training, predisposing to muscle fatigue, leading to and leading to reduced performance. During exercise, the respiratory muscles (RMs) increase oxygen consumption, which can lead to fatigue, this, and through the metaboreflex it causes, will generate a reduction in peripheral blood flow, which can result in fatigue and a reduction in performance. of the athlete. Respiratory muscle training (RMT) can help improve the fitness of RMs. The objective was to investigate the effectiveness of TMR in reducing the perception of exertion (RPE) and dyspnea (PSD), and in improving performance in n amateur CrossFit® athletes For this, an experimental study was carried out, in the style of a series of cases. Respiratory muscle strength was measured by manuvacuometry, RPE and PSD during Benchmark training, as well as evaluation of the athlete's performance in training before and after the intervention, which carried out pre and post intervention tests, which consisted of manuvacuometer, Benchmark test with measurement of the PSE and PSD during its implementation. The intervention consisted of a TMR protocol, which consisted of a TMR protocol, performed for 6 weeks, with graded loads. The sample consisted of 3 athletes, with an average age of 31 years ± 4,66 years; with a mean BMI of 24.29 kg/m² ±2,01 kg/m; ². The athletes showed improvements in the maximum inspiratory and expiratory pressure, reduction in PSE and PSD, as well as in the and, still, the Benchmark performance time decreased. Thus, we conclude that TMR is able to improve the performance of athletes, as well as improve their PSE and PSD.
