Isolated and combined effects of different post-exercise recovery strategies in crossfit athletes: protocol for clinical trial, crossover, randomized, controlled and blind ; Efeitos isolados e combinados de diferentes estratégias de recuperação pós-exercício em atletas de crossfit®: protocolo para ensaio clínico, cruzado, randomizado, controlado e cego

Introduction: CrossFit® is a high-intensity exercise modality whose most intense part of the training and championship is called WOD (workout of the day). Competitions are held with several WODs in sequence and on consecutive days, which can cause muscle fatigue and increase the athlete's propensity for injuries. In some sports, in order to minimize such consequences, therapeutic devices have been used to accelerate muscle recovery or modulate the damage caused after strenuous exercise. However, it is not known which is the best resource to promote faster and more efficient muscle recovery in CrossFit® athletes.Objective: Therefore, the objective of this study is to compare the isolated and combined effects of three different therapeutic resources: TFBM-CMe, TOC and CPI on muscle recovery in CrossFit® athletes.Methodology: A randomized, controlled, crossover and blind clinical trial will be conducted. With voluntary participation of male CrossFit® athletes aged 18 to 36 years, who will be randomly distributed according to the crossed order of treatment types (control/passive recovery, TFBM-CMe, OCD and CPI) to be received in the 4 weeks of procedure. Muscle recovery will be assessed before any intervention (baseline) and 1h, 24h and 48h after performing the WOD to induce fatigue. The assessments will consist of the functional test, the Countermovement Jump Test (CMJ); subjective perception of effort/fatigue measured by the CR-100 scale and physiological variables through the analysis of oxidative stress. The data will be analyzed statistically and the considered level of significance will be p<0.05.Discussion: Through the results of the functional and biochemical evaluation of the comparative study, we hope to clarify the best resource to help with performance and delay muscle fatigue, consequently reducing the risk of injury. ; Introdução: O CrossFit® é uma modalidade de exercícios de alta intensidade cuja parte mais intensa do treinamento e campeonato é chamada de WOD (workout of the day).
