Jiu-jitsu athletes’ cardiovascular responses in an adapted burpee test

Abstract

Sports combat practitioners number is increasing, and one of the most popular sports is Brazilian Jiu - Jitsu (BJJ), thus it is necessary to use cardiovascular monitoring methods to estimate heart effort. As sport combat a dynamic exercise, adaptation of spo rt test to resemble one increase its accuracy. The aim study is to determine cardiovascular responses in BJJ athletes through an adapted Burpee test. The sample selection was not probabilistic, for convenience, and comprised 54 fighters BJJ male 18 - 39 year s old. Before, during and after test application were monitored: systolic blood pressure (SBP) and diastolic (DBP), resting heart rate (HR r ), mean (HR m ) and maximum (HR max ) by auscultation and frequencymeter for calculation of mean BP (MBP), double product (DP) and effort percentage (% effort). After analysis, we observed a significant increase in SBP and HR pre and post - test (p<0.05) and DBP reduction (p<0.05). Regarding the DP and % effort, 25770 + 3707.6 mmHg.bpm and 87.0 + 6.3, respectively, they yielded va lues comparable to high - intensity continuous aerobic exercise. We conclude, therefore, that cardiovascular responses found suggest significant changes in the surveyed athletes, these ones being exposed to cardiac overload comparable to a continuous aerobic activity of high intensity, requiring adequate monitoring.
