Several gene polymorphisms have recently been reported as determinants of (1) daily physical activities, (2) execution of exercises, or (3) continuance of physical training in individuals from the general population. Therefore, the aim of this study was to investigate whether the ACTN3 R577X polymorphism influences the fitness status and tendency for physical activities and exercise in elderly Japanese women. The results suggest that the ACTN3 RR and R alleles also influence the fitness status and tendency for performing physical activities in elderly Japanese women, as roughly similar as angiotensin-converting enzyme genotype and aromatase gene polymorphism.
（本研究は、女性高齢者における身体能力とACTN3 R577X遺伝子多型との関連性ついて比較検討したものである。結果から、女性高齢者においては体力レベルとACTN3 R577X遺伝子多型との関連性は認められなかったものの、女性高齢者の体力は遺伝子的要因よりも運動習慣との関連性が高いとの結果について報告したものでる。
