Previous studies have reported that the alpha-actinin-3 (ACTN3) and angiotensin-converting enzyme (ACE) gene polymorphisms are associated with sports performance, muscle strength, muscle power, and endurance. Competitive judo requires high levels of muscle power, muscle strength, and endurance. However, thus far, associations between these gene polymorphisms and muscle power in judo athletes have not been reported. The purpose of this study was to investigate the relationship between ACTN3 and/or ACE gene polymorphisms and middle power in judo athletes. This study recruited 79 male judo athletes from a top-level university in Japan. Genomic DNA was extracted from the saliva sample taken from each athlete. Genotyping using either polymerase chain reaction (PCR)-restriction fragment length polymorphism or PCR was performed to detect ACTN3 (rs1815739) and ACE (rs1799752) gene polymorphisms. Each athlete also performed a 30-s Wingate anaerobic test with a resistance equal to 4.5% of the athlete’s body weight.One-way analysis of variance revealed a significant difference in middle power relative to weight among the ACTN3 genotype groups (p<0.05). In other words, RX individuals showed significantly higher middle power than XX individuals (p<0.05). Moreover, middle power relative to weight was higher in individuals with the RR+RX genotype than in those with the XX genotype (p<0.05). However, there were no significant differences in the ACE genotype.The results of the present study suggest that ACTN3 but not ACE gene polymorphisms may be associated with middle power in judo athletes.

〔目的〕本研究は,女性柔道選手の月経期間別の月経随伴症状と生活習慣との関連性について明らかにすることを目的とした.〔対象と方法〕18歳から21歳までの女性柔道選手169名を対象とし,プロフィール,柔道実施状況,生活習慣で構成された質問紙と月経随伴症状に関する質問紙(MDQ)調査を実施した.〔結果〕月経前および月経中のMDQの総得点と平日の睡眠時間との間に負の相関が認められた.平日および休日の睡眠時間が短い女性柔道選手は月経随伴症状の得点が高値を示す関係性が明らかとなった.〔結語〕女性柔道選手において月経前や月経中は月経随伴症状が悪化することから,睡眠時間をはじめとした生活習慣への注意が必要である.
