Abstract
Objective: This study aimed to analyze whether there are differences between the sleep quality of amateur and professional karate fighters. Methodology: Nineteen male Karate fighters participated in the study, where ten fighters were amateur (regional championships), aged 32.3 ±11.2 years, the body mass of 79.1 ±13.1 kg, and nine fighters were professionals (world championships), aged 26.8 ±10.5 years, the weight of 66.3 ±8.2 kg. All volunteers answered the PSQI-Br instrument, validated to Brazilian Portuguese. The Mann-Whitney U non-parametric test was used for statistical analysis, p-value, U value, Z score, and effect size. Results and discussion: There was a statistically significant difference in bedtime and sleep duration, indicating worse results for professional karate fighters. There were no differences in overall sleep quality; however, both groups are classified as poor sleepers. Conclusion: Therefore, amateur and professional karate fighters have poor sleep quality, generating several factors that negatively affect health and performance.
