中文摘要 |
本研究之主要目的在探討不同強度阻抗運動對肌酸激(creatine kinase,CK)與丙二醛(malondialdehyde,MDA)之影響。受試者為20名男性學生,平均年齡21.20±1.40歲,身高175.05±6.66公分,體重71.50±8.19公斤。本研究採重複量數設計,以隨機方式讓受試者分別接受美國運動醫學會(ACSM)推薦負荷強度之8RM與15RM,訓練的阻抗運動項目為:仰臥推舉(bench press)、蹲舉(half squat)、臂屈(arm curls)、大腿伸踢(leg extension)、正握拉槓(lat pulldown)、腿背彎舉(leg curls)、仰臥起坐(sit-up)、負槓前跨(front dumbbell lunge)等八項。實施阻抗運動時,每次完成三組,組間休息2分鐘。不同強度之間測驗的間隔時間為7天。受試者在運動前與運動後瞬間、運動後24小時及48時抽血分析血液中肌酸激與丙二醛的濃度。結果發現在8RM運動後48小時,CK值明顯高於安靜值,不同強度的CK值,則8RM的CK值比15RM的CK值高;而MDA,在8RM和15RM 運動後瞬間及運動後24小時皆有顯著上升,8RM與15RM則無明顯差異存在。本研究結果顯示,8RM與15RM間的阻抗運動,造成骨骼肌相當衝擊與氧化壓力。 |
英文摘要 |
The purpose of this study was to evaluate the effect of different intensity resistance on creatine kinae and malondialdehyde. Twenty (20) male college students were recruited from the NTNU. All subjects(age=21.6±1.65yrs, ht=178.50±6.59cm, wt=74.70±7.68kg) in both groups participated in 8RM and 15RM resistance exercise (including bench press, half squat, arm curls, leg extension, lat pull-down, leg curls, sit-up and front dumbbell lunge) in balanced order. The blood samples for malondialdehyde (MDA), creatine kinase(CK) determination were taken before exercise, immediately, 24 h and 48 h post-exercise from the antecubital vein. The data was analyzed by two-way ANOVA with repeated measures. The results were as follows: CK activity in 8RM was significantly elevated at 48 h after exercise. The CK values significantly higher in the 8RM than 15RM. Serum MDA concentration was significantly elevated after exercise and 24 h after exercise. No significant difference in MDA levels was found between 8RM and 15RM intensities. Conclusion: The MDA activities of both groups were significantly elevated after exercise and 24 h after resistance exercise. Results from this study indicate that both of 8 RM and 12 RM resistance exercise induce somewhat tissue damage and oxygen stress on skeleton muscles. |
