摘要

目的：觀察連續實施三天費力跑步運動（80% HRR，20分鐘跑步）的血管及可體松壓力反應。方法：10位年輕男性大學生（年齡23.1 ± 2.7歲，身高171.90 ± 5.15公分，體重69.32 ± 5.75公斤）。經最大努力運動測試後，實施三天費力跑步運動。運動前後包含30分鐘的安靜值及恢復期測量。以重覆量數單因子與二因子變異數分析，分別比較心跳率及血壓連續三天運動的平均安靜值與恢復期差異；以及比較三天運動之間可體松濃度增加百分比的差異。結果：心跳率及血壓的安靜值、恢復期以及運動後可體松濃度增加百分比三天之間皆無顯著差異（p ＞ .05），而運動後可體松濃度顯著大於運動前(0.134 ± 0.078 vs. 0.092 ± 0.061微克／合升，p ＜ .05）。結論：連續實施三天費力跑步運動，身體的壓力反應程度皆維持相同。

Purpose: Observe changes of cardiovascular and hormone (cortisol) stress responses during 3 consecutive days of vigorous running exercise (D1, D2 & D3). Methods: The present study recruited 10 healthy young males (age 23.1 ± 2.7 yrs, height 171.90 ± 5.15 cm, weight 69.32 ± 5.75 kg) from the department of physical education and requiring all of subjects completed a VO_2max test before taking part in 3 times of vigorous running exercise (20-minute 80%HRR treadmill exercise), with 24- hour rest between each exercise. Measure heart rates and blood pressures during 30 minutes before and after (1, 3, 5, 10, 15, 20, 25 and 30 min after exercise) each exercise. Cortisol were measured after 30 min seated rest and exercise. Data analyses were conducted by repeated measured one-way ANOVA for cardiovascular responses. Compared the responses differences between each exercise. Twoway ANOVA was used to compare the differences of the percentage increase in cortisol level between 3 days. Results: There were no significant differences with respect to changes of heart rates and blood pressures between D1, D2 and D3, regardless of pre- or post-exercise (p ＞ .05). The average cortisol level of post-exercises are significantly greater than pre-exercises (0.134 ± 0.078 vs. 0.092 ± 0.061 μg/ dl, p ＜ .05). But there were no significant differences between 3 days’ percentage increases (p ＞ .05). Conclusion: The cardiovascular and hormonal responses to the 3 days of vigorous running exercise do not vary significantly from one another which shows that 3 consecutive days of vigorous running exercise do not affect the magnitude of stress responses.
