Abstract: Recovery in the intervals between high-intensity efforts is associated with high heart rate variability (HRV) in sports. The current study analysed the association of heart rate (HR) and HRV with performance in a specific test for Brazilian jiu-jitsu athletes (JJAPT) and the HR recovery (HRR). Twenty Brazilian jiu-jitsu (BJJ) male athletes (aged: 18 to 45 years, 1.76 ± 0.07 m, 82.6 ± 12.6 kg), graduated from white to black belt, underwent HRV analysis at rest and the JJAPT. The number of repetitions in each set, fatigue index, power drop, and HR were recorded. Repeated measures ANOVA and the Bonferroni post hoc test were used to analyse performance. Multivariate linear regression analysis and the Spearman rank correlation test were used to detect associations between performance and age, BMI, time of BJJ practice, HR, and HRV indices. HR and HRV indices did not demonstrate associations with performance in the JJAPT. Performance showed moderate correlations with BMI (r = −0.50, p = 0.02), HRpeak (r = −0.47, p = 0.03), HRRset4 (r = −0.48, p = 0.03), and HRRset5 (r = −0.47, p = 0.03). HR was correlated with anaerobic performance. However, HRV indices had little impact on recovery between sets.
