預先處理對基隆山健走之肌肉損傷的探討
Discussion on preconditioning effect of the muscle damage caused by hiking in Keelung Mountain
摘要
背景：沒有產生肌肉損傷的預先處理會降低後面高強度刺激所引起的肌肉損傷。但目前沒有研究針對郊山健走的情形作一探討。目的：探討預先處理對攀登基隆山肌肉損傷指標（運動後連續三天的肌酸激酶活性、主觀肌肉疼痛、客觀肌肉疼痛和簡易日常生活活動性量表）之反應。方法：招募20名志願健康運動愛好者，填寫疾病調查表後，先進行基礎耐力檢測（坡度+10%，速度從2km/h直到7km/h，一直到受試者無法再順利進行或實施到7km/h即停止），而找出個人的有氧與無氧閾值，再以個人的有氧閾值速度採平衡順序法分為兩組（預先處理組，n=10；控制組，n=10）。兩組均要進行基隆山的攀登，而實驗組在登山前一天預先處理（個人有氧閾值速度*0.6、坡度10%，負重8Kg）10min。以獨立樣本t檢定來探討兩組之間肌肉損傷（MD）之差異，單因子變異數分析來探討不同時間點MD的差異，研究顯著水準皆定為α=.05。結語：本研究條件下的預先處理無法呈現重複訓練效果之效益，短時間（1hr）郊山健走的CK活性對運動習慣者無法成為指標依據。此外，經由量表與實際測試，攀登後第一天都是疼痛感最多的，至第三天則接近攀登前的情況。研究數據可供休閒登山者參考。

Background: The protective effect conferred by non- damaging or minor-damaging low-intensity ECC or maximal isometric contractions at a long muscle length. However, there is no research to discuss the situation for mountain hiking. Purpose: To explore the response of protective effect to the muscle damaging index of Keelung Mountain hiking. Method: Recruit 20 volunteer exercise subjects and perform basic endurance testing (gradient +10%, speed from 2km/h to 7km/h, until the subjects can no longer proceed smoothly or stop at 7km/h), And get personal aerobic and anaerobic thresholds. Using the individual aerobic threshold speed, the balance sequence method was used to divide them into two groups (test group, n=10; control group, n=10). Both groups were required to perform Keelung Mountain walking, while the experimental group performed a test (personal aerobic threshold speed*0.6, slope 10%, carrying 8Kg) for 10 minutes the day before the walking. The independent sample t test was used to explore the difference in muscle damage (MD) between the two groups, and the single factor variance analysis was used to explore the difference in MD at different time points. The significance level of the study was set as α = .05. Conclusion: Under the conditions of this study, the benefits of repetitive training effects cannot be shown. The CK activity of short -term (1hr) suburban mountain hikers cannot be an indicator basis for people with exercise habits. In addition, through scales and tests, the first day after hiking is the most painful, and the third day is close to the basic line. The research data can be used as a reference for recreational hikers.
