中文摘要
背景：當激烈運動後，在肌肉有酸痛及損傷的情形下，是否應該繼續從事運動？關於這個問題，現有文獻尚未有完整的論述。有許多運動員在肌肉損傷及酸痛的情況下仍然會繼續運動，而過去的文獻只有探討讓損傷的肌肉繼續運動，是否會加重受傷情形或者會增進肌肉功能的恢復。對於耐力性運動項目，肌肉功能不應是被考量的唯一指標，與耐力表現具有高度相關的跑步經濟性也應一併討論。目的：在探討肌肉損傷後從事6天不同強度的動態恢復活動（50%、60%、70% VO2max），對肌肉功能恢復及跑步經濟性的影響。方法：本研究以40名自願參加本實驗之大學體育相關科系學生（男性32人；女性8人）為受試對象。受試者先接受VO2max及跑步經濟性測驗後，再將受試者隨機分派E50組（50% VO2max；n=10；♂＝8、♀=2）、E60組（60% VO2max；n=10；♂＝8、♀=2）、E70組（70% VO2max；n=10；♂＝8、♀=2）、CON組（控制組；n=10；♂＝8、♀=2）。之後讓受試者在跑步機上以70% VO2max 的強度進行一次30分鐘的下坡跑（-15%），來誘發股四頭肌產生肌肉損傷。在下坡跑後第1-6天期間，分別以不同的強度進行每天30分鐘的跑步運動。各組在下坡跑前、後第0-7天接受肌肉酸痛及最大自主等長收縮肌力（MVC）測量；各組在下坡跑前、後第1、3、5、7天抽血檢驗肌酸激酉每（CK）、乳酸脫氫酉每（LDH）活性；各組在下坡跑後第2、5、7天接受跑步經濟性測驗。結果：在下坡跑後第4-7天，CON組、E50組這兩組的MVC恢復情形顯著高於E70組 (p<.05)。在下坡跑後第7天的跑步經濟性測驗中，E50組顯著優於CON組、E70組這兩組 (p<.05)。在CK、LDH、肌肉酸痛指數等指標上，不同四組在不同時間點上均無顯著差異 (p>.05)。結論：1.最大肌力值若要儘速恢復，採用完全休息或中強度的動態恢復（約50﹪VO2max），是較好的選擇。越高的動態恢復強度，越會延緩MVC的恢復時程。2.過高的動態恢復強度（70% VO2max）或不做動態恢復的處理方式，則對跑步經濟性有不利的影響。3.同時考量跑步經濟性及MVC恢復情形因素，則中強度的動態恢復（50% VO2max）比不從事動態恢復和高強度動態恢復來得好。

The effect of the different intensities of active recovery on muscle function and running economy after exercise-induced muscle damage

ABSTRACT
Background：Should athlete continue to exercise when muscles are sored after strenuous exercise？ Current literatures do not provide clear answers to this question. Post studies discussed the effect of exercise on muscle function after exercise-induced muscle damage. However, muscle function is not the only concern for endurance runners. Running economy should also be considered. Purpose：To determine the effect of a 6-day different intensities active recovery (50%、60%、70% VO2max) on muscle function and running economy after exercise-induced muscle damage. Methods：Forty Physical Education students (32 males & 8 females) took the VO2max and running economy test first. Then they were randomly assigned into 4 groups: E50（50% VO2max；n=10；♂＝8、♀=2）, E60（60% VO2max；n=10；♂＝8、♀=2）, E70（70% VO2max；n=10；♂＝8、♀=2） and CON（control；n=10；♂＝8、♀=2）. A 30-min downhill running (-15%) at 70% VO2max was used to cause muscle damage. A 30-min active recovery running exercise was performed everyday for the following 6 days. Maximal isometric voluntary contraction strength (MVC) and muscle soreness were measured before, immediately after and 1, 2, 3, 4, 5, 6, 7 days after downhill running. Creatine kinase (CK) and lactate dehydrogenase (LDH) activities were also tested before, immediately after and 1, 3, 5, 7 days after downhill running. Running economy was determined 2, 5, 7 days after downhill running. Results：On the days 4 –7, both the CON’s and E50’s MVC were significantly higher than the E70 (p<.05). On the seventh day of the running economy test after downhill running, E50 was significantly different as compared to CON and E70（p<.05）. No significant differences among groups in CK activity, LDH activity and muscle soreness (p>.05) were observed. Conclusions：1. Rest or moderate intensity active recovery (about 50% VO2max) is better for MVC recovery. Higher intensity of active recovery, will delay the normal course of MVC recovery. 2. Higher intensity of active recovery or rest was harmful to running economy. 3. When consider running economy and MVC together, moderate intensity of active recovery (about 50% VO2max) was better than rest or high intensity active recovery.


Key words：active recovery, muscle damage, running economy.
