Characterization of sleep quality in Brazilian Jiu-Jitsu fighters

Introduction Sleep quality can positively or negatively influences the physical performance of Brazilian Jiu-Jitsu fighters; however, the literature does not indicate whether the sleep quality of these fighters is good or poor. Objective Characterization of the sleep quality of Brazilian Jiu-Jitsu (BJJ) fighters, stratifying by weight category and color belts. Material and Methods A descriptive study that featured with 175 BJJ fighters, the Pittsburgh Sleep Quality Index (PSQI) was applied to assess sleep quality. Mean, standard deviation and 95% confidence interval of mean were used to characterize the data. Results All groups, regardless of weight category or color rank, were classified as poor sleepers (PSQI=5), which indicates a low sleep quality. Conclusion The sleep of BJJ fighters is characterized as poor, which may indicate negative outcomes in technical and physical performance.
