在從事激烈運動後的24~48小時內所產生的肌肉酸痛稱為延遲性肌肉酸痛(DOMS),它是每一個人幾乎都會經歷的一種經驗。過去有許多學者試著用不同的方式,想找出一些有效的方法來處理DOMS所產生的一些不適症狀,但是至今仍然沒有肯定的結果出現。本研究的目的在探討冷水浸浴法及冷熱交替法對DOMS的效果。受試者為18位男性,平均無齡為23.0±2.4歲,身高173.3±5.5公分,體重66.8±5.3公斤。以隨機的方式將受試者分為三組:冷水浸浴組(n=6)、冷熱交替法組(n=6)與控制組(n=6)。首先測量受試者非慣用手之肘關節活動度、疼痛指數及最大等長肌力。再利用反覆的離心運動使手臂屈肌達到延遲性肌肉酸痛的狀態,並在誘發肌肉酸痛後的0、24、48及72小時,接受20分鐘的冷水及冷熱交替法處理,隔天再評估其非慣用手之肘關節活動度、疼痛指數及最大等長肌力。結果發現冷水浸浴法及冷熱交替法對肘關節活動度及疼痛指數都有明顯且正面的效果,且與控制組達到顯著差異,但比較冷水浸浴組及冷熱交替組兩組之效果則無顯著差異存在。至於在最大等長肌力上,三組則無顯著差異存在。因此冷水浸浴法與冷熱交替法有助於關節活動度及疼痛等症狀的改善。
The pain occurs after strenuous exercise and during 24~48 hour is referred as delayed onset muscle soreness (DOMS). It is a common phenomenon that everyone has experienced. In the past, a lot of scholars tried to find out some effective methods to deal with the uncomfortable symptoms of DOMS, but the result was still uncertain. The purpose of this study was to determine the effect of cold water immersion and contrast therapy on the treatment of DOMS. 18 male volunteers, with age, height and weight of 23.0±2.4 years (mean ± SD), 173.3±5.5 cm and 66.8±5.3 kg respectively participated in this study. All of them were allocated to cold water immersion (n=6), contrast therapy (n=6) or control group (no treatment, n=6) in balance order. Range of motion (ROM), soreness index and maximal isometric strength of their wonted elbow joint were evaluated. DOMS was induced through repeated eccentric exercise of their elbow flexors. Subjects treated with cold water immersion and contrast therapy for 20 min, and than measured ROM, soreness index and maximum isometric strength in 24, 48 and 72 hours post exercise. As the result, cold water immersion and contrast therapy were effective in ROM and soreness index. No significant difference was found between effects of cold water immersion and contrast therapy groups. As to effects on maximum isometric strength, there were no significant differences in all groups. The study concluded that cold water immersion and contrast therapy alleviate the pain and ROM of DOMS.
