abstract
本研究は早朝運動時の安全性を検討するため循環器学的・生化学的検査を行なったものである. 対象: 本学体育科男子学生10名である. 方法: 運動負荷はトレッドミル走とし, 強度は60%VO2maxとした. 実験条件はA: 早朝空腹時, B: 早朝糖質摂取時, C: 昼食後2時間とした. 検査項目: ①起立試験・寒冷昇圧試験 ②運動中の心拍数・血圧・心電図 ③血清生化学検査(BS, IRI, FFA, CPK, UA, LA)である.

実験成績: ①起立試験・寒冷昇圧試験によって, 早朝は午後に比して循環調節機能が劣っており, 交感神経緊張不良状態を示した. ②運動中の心拍数・血圧は条件Aでは開始後15分までは運動に対する順応が遅れた. しかし条件Bでは遅れは見られなかった. ③生化学検査ではAにおいて低いBSとIRIを示し, また最も高いFFA値を示した. 心電図は異常を呈しなかったが, 以上の成績から早朝空腹のジョギングは好ましくないことが判明した. しかし早朝でも糖質を摂取すれば安全であると考えられた.
abstract
This paper is related to clarify the safety of jogging in the early morning. Cardio-vascular and serum biochemical analysis were carried out as follows in 10 healthy male students of Hiroshima Univ. Dept. Physical Education. Design of experiment was, A: early morning at fast, B: early morning at carbohydrate (100 g) intake, C: two hours after lunch. Intensity of exercise was 60% VO_2 max and duration was thirty minutes. Items of examination were a) postural test and cold pressor test in the early morning and afternoon, b) HR and BP during exercise, c) serum biochemical parameters at before and after (BS, IRI, FFA, CPK, UA, LA).

Group A showed the lower heart rate, blood pressure and higher reactivity to postural and cold pressor test than other two groups. Group A resulted in lower HR and BP than those observed in group B, C during initial 15 minutes. In group A, lower serum BS and IRI response at both before and after, and higher levels of FFA at after exercise were observed.

These results suggested that a remarkable delay of cardio-vascular adaptation and rise of FFA might be a risk factor against the safety of exercise in the early morning.
