Outline of Final Research Achievements

This study was to observed endocrine responses during maximal endurance exercise and resistance exercise in female athletes with normal and abnormal menstruation. As a results,the levels of IGF-1 pre, post, and 30 minutes after the maximum endurance exercise were significantly lower in the abnormal menstrual group than in the normal menstrual group (p<0.05).The IGF-1 is involved in muscle protein synthesis and bone formation, suggesting that it may affect trainability in cases of prolonged menstrual abnormalities.

Academic Significance and Societal Importance of the Research Achievements

正常月経および月経異常の女性アスリートの運動時生理反応・トレーニング反応を比較することによって,月経異常がスポーツパフォーマンスに与える影響が明らかになる.本研究によって月経異常がトレーナビリティおよびスポーツパフォーマンスの低下を引き起こすことが明らかになれば,アスリートや指導者に月経異常の予防・改善の重要性を示すことが可能となる.本研究で得られた知見は,女性アスリートの健康管理,ひいては競技力向上に役立つものと期待される.
