Abstract

Objective: To analyze the behavior of blood pressure (BP), heart rate (HR) and its variability (HRV) in CrossFit® practitioners.

Material and Methods: The CrossFit® method was applied to 10 individuals of both sexes, three times a week, for twelve weeks. The outcome variables were anthropometric measures, aerobic capacity, BP, HR and HRV at rest and after twelve weeks of training. The aerobic capacity was measured from a progressive test in a cycle ergometer and the HRV through records in a Polar brand frequency meter. Statistical comparisons were made using the Student t test.

Results: Only the variable lean mass (kg) showed a statistically significant difference (p=0.058). The registry variables of the HRV (SD1 and SD2) did not present a significant difference, however, they had a small increase. BP remained stable and unchanged before and after training.

Conclusion: The beneficial influence of CrossFit® training on subjects’ body composition and HRV values suggests that this type of training plays an important role in maintaining the health of normal individuals, as well as in cardiac parasympathetic modulation.
