| Research Abstract |
The purpose of this study was to investigate the association between ACTN3 genotype and muscle function and its adaptability in Japanese. The results indicated that RR genotype might correlate with fast muscle fiber composition. In addition, not only sprinters but also endurance runners could benefit from RR genotype. However, delayed-onset of muscle soreness was not associated with ACTN3 genotype.
