不同強度之耐力運動對血液中維生素C、E濃度的影響

本研究之目的在探討不同強度運動對血液中維生素C、維生素E濃度的影響。受試者爲12名最大攝氣量爲61.7±2.9ml/kg/min之長跑選手，平均年齡18.8±3.1歲，身高169.8±3.1公分，體重59.6±5.7公觔。本研究採同一受試者重複測量之設計，受試者以隨方式分別接受85% VO2max及60% VO2max運動強度在原地跑步機上跑30分鍾等二種不同強度跑步，不同強度之間的測驗時間爲10天。受試者在跑步前、後及跑步後60分鍾抽血分析血液中之維生素C、維生素E之濃度，結果發現維生素C濃度不管在任何強度下之運動皆沒有明顯改變，維生素E在85% VO2max之運動後及運動後60分鍾有明顯的改變。根據本研究之研究結果可知，運動如以健康爲目的應以60% VO2max之運動爲宜，因爲在此強度下，運動後不會造成維生素C及維生素E顯著的減少，故在運動前，似科不必補充維生素C及維生素E。但是選手若需在最短時間在到最大訓練效果，可攷慮接受85%VO2max之運動，但切記訓練後應特別注意保養身體，並盡量在運動前補充維生素E。

The purpose of this study was to evaluate the effects of different running intensities on Vitamin C and Vitamin E concentrations in blood. Twelve (12) long-distance runners (age=18.8±3.10 yrs, ht=169.8±3.10cm, wt=59.6±3.90 kg, VO2max=61.7±5.7 ml/kg/min) were randomly assigned to one of the following two groups, the 85% VO2max max group and a 60% VO2max group. Every runner was tested repeatedly after ten days. The blood samples were collected before, immediately after, and one hour after exercise for the measurement of Vitamin C & Vitamin E. Levels of Vitamin C after exercise were found to be not significantly different from those before exercise in all the two different intensity groups. The blood levels of Vitamin E immediately after, and one hour after exercise were significantly different from those before exercise in the 85% VO2max. groups. Conclusion: Running velocity at 60% VO2max is the best intensity for health maintenance. The 85% VO2max may be more effective method for the professional athlete training. Intake vitamin E everyday for athlete is recommended.
