Outline of Final Research Achievements

The aim of this study was to investigate the influence of exercise habits on oxidative stress risk by measuring blood oxidative stress and antioxidant capacity in female university students with normal menstrual cycles. Additionally, the study aimed to examine the effects of the menstrual cycle on oxidative stress and endurance performance in female student athletes by conducting progressive exercise load tests during the menstrual and luteal phases.
The results of this study demonstrated that oxidative stress-related indicators at rest in female university students were not influenced by exercise habits or menstrual cycle. Furthermore, in female student athletes, the menstrual cycle was found to affect the exercise-induced oxidative stress but did not have an impact on antioxidant capacity.

Academic Significance and Societal Importance of the Research Achievements

これまで男性で検討されてきた運動時の生理反応や，単一の性周期で検討されてきた酸化ストレス応答の研究成果をそのまま当てはめるのではなく，女性特有のホルモン動態と運動時の生理応答について細やかに観察を行ったものである．現代女性のアクティブなライフスタイルのなかで，女性ホルモン動態と酸化ストレス応答について，特に性周期と短期的および長期的な運動の影響に着目していることに意義がある．本研究の結果は，女性のライフスタイルに応じた運動に伴う酸化ストレスリスクの軽減につなげ，アスリートのみならず，運動処方や健康づくり運動の実践の現場に活用できるものである．
