Background: The aim of this study was to evaluate the distribution of ACE-I/D polymorphisms on Brazilian football players performance in aerobic capacity, strength and speed tests.
Methods: The participants in this study were 212 Brazilian first division male football players genotyped in DD, ID or II. Genotyping of DNA from leucocytes was performed using polymerase chain reaction and restriction fragment length polymorphism methods. We evaluated speed using a 30-meter sprint test with speed measured at 10 meters (V10), 20 meters (V20), and 30 meters (V30); muscular strength using counter-movement-jump and squat jump tests; and aerobic endurance using the Yo-Yo endurance test. The athletes were ranked in ascending order according to their performance in each test and divided into quartiles: first quartile (0-25%, weak), second (25-50%, normal), third (50-75%, good), and fourth (75-100%, excellent); these were clustered according to genotype frequency.
Results: We identified significant differences in the V20 test values and in the aerobic capacity test. Higher frequencies of the ACE-DD genotype were observed in the excellent performance group in the V20. In the aerobic capacity test, higher frequencies of the ACE-II genotype were observed in excellent and good performance groups.
Conclusions: Players with higher performance in anaerobic and aerobic tests are ACE-DD and ACE-II genotypes, respectively.
