Acute hypotensive effect and autonomic response after a Brazilian jiu-jitsu training session in federated athletes

Background The acute hypotensive effect after a physical exercise session can be a valuable tool for reducing long-term cardiovascular risk. Aim To evaluate blood pressure and heart rate variability (HRV) pre/post a single Brazilian Jiu-Jitsu (BJJ) training session. Methods Eighteen athletes were selected, (age 31 ± 10; BMI 25.9 ± 2.5), from higher to lower rank and collected/analyzed pre/post HRV in the domain of time, of frequency and of non-linear indices. The statistic included the Kolmogorov–Smirnov test, Levene test, and ANOVA of two inputs with post hoc by Holm Sidak. In addition, the unpaired t-Student;s test and the Mann–Whitney test were applied. The level of significance was p
