Abstract

Physiological responses over CrossFit athletes in the Brazil CrossFit championship

Highlights

Founded in 2000, CrossFit is a high intensity interval training program that can improve physiological responses enabling numerous benefits [1,2,3]
Zecchin-Oliveira AM (2020) Physiological responses over CrossFit athletes in the Brazil CrossFit championship were analysed in the 2019 semi-final of Brazil CrossFit Championship (BCC), that is one of the phases of competition which lead the winners to the CrossFit Games; each phase there is only one man and 1 woman, and 1 team that is able to compete the CrossFit Games
The present study is a new way of investigation to the coaches understand how the athlete physiological responses over a competition in real time mensuration is

Summary

Introduction

Founded in 2000, CrossFit is a high intensity interval training program that can improve physiological responses enabling numerous benefits [1,2,3]. Most of the CrossFit studies evaluated injury and physical capacity, in eventual practitioners (none in elite athletes). The basic physiological responses such intensity analyses of the competition, excessive postexercise oxygen consumption (EPOC) levels and calories expenditure are remaining unknown in elite CrossFit athletes. Studies evaluating elite CrossFit athletes exposed activation of aerobic and anaerobic responses through short and very intense workout of the day (WOD [specific CrossFit training]) and high lactate concentration after one WOD englobing moderate volume and high intensity [7,8]. A recent study evaluates physiological levels of testosterone, IL-1, IL10, etc in CrossFit amateur athletes in a competition. Well trained CrossFit practitioners seem to take lower intensity than elite CrossFit athletes, and it leads researchers to believe that CrossFit is a fast adaptation practice through different group of age and levels [8,9,10,11]. Schubert at al. found that amateur CrossFit practitioners can account for a significant portion of daily energy expenditure, and consecutive training can induce meaningful weight loss [12]
