| Outline of Final Research Achievements |
The purpose of this study was to investigate the association between gene polymorphisms and judo status, body composition and muscle strength in judo athletes.
The subjects in the present study were 216 male judo athletes. Genotyping by PCR-RFLP was used to detect alpha-actinin-3 (ACTN3), Angiotensin-converting enzyme (ACE) and Insulin-like growth factor 2 (IGF2) gene polymorphisms. They were divided into three groups based on their results in national or international competitions. Body composition and muscle strength were measured. The results indicate that the IGF2 gene polymorphism may be associated with judo status. Moreover, IGF2 and ACTN3 gene polymorphisms are associated with muscle strength in judo athletes.
