摘要

本研究目的在探討雙臂與單臂捷泳之動態恢復，對游泳選手訓練後血乳酸排除及運動表現之影響。研究對象是為12名男性游泳選手，平均年齡17.42歲；平均訓練年資6.83年。實驗方法共分2次，以平衡次序法分別進行雙臂與單臂捷泳動態恢復實驗。實驗過程包含：以雙臂與單臂100公尺捷泳最佳成績秒數之165%為恢復游速，及進行100公尺捷泳全力游後，再接受20分鐘雙臂與單臂捷泳動作動態恢復實驗。動態恢復實驗後1分鐘與3分鐘分別檢測血乳酸、心跳率，每次實驗處理間隔24小時，並於動態恢復實驗後休息一小時，再次進行200公尺捷泳再測全力游實驗，進一步分析游泳全力游之成績、血乳酸及心跳率。將檢測所得資料，先以Microsoft Excel敘述性統計，分析雙臂與單臂捷泳動態恢復後血乳酸值，以了解血乳酸排除之狀況及對運動表現之影響狀況。進一步以SPSS for Windows18.0之重複量數單因子變異數分析、無母數統計－相依樣本t考驗、皮爾森相關係數、單因子變異數分析進行分析。結果發現：在動態恢復後1分鐘與3分鐘之血乳酸濃度上，血乳酸濃度皆顯著低於單臂動態恢復處理（1分鐘血乳酸：2.14vs.3.07, p ＜.01；3分鐘：1.81vs.2.85, p ＜.01）。另在，200公尺捷泳再測全力游運動表現上，雙臂組成績顯著優於單臂組（143.16秒vs.146.09秒, p＜.05）。研究顯示，動態恢復的確能降低心跳率，且有助於選手排除血乳酸，尤其以雙臂捷泳進行動態恢復，能有效降低血乳酸濃度，並可提升隨後再測的運動表現。因此，建議游泳教練們在訓練選手捷泳或比賽捷泳時，可指導選手使用雙臂捷泳進行動態恢復，有助於血乳酸排除及運動表現，且比單臂捷泳動態恢復佳。

The study aimed to examine the effects of dynamic rehabilitation on blood lactic acid (LAC) exclusion and athletes' performance for both double-arm and single-arm breaststroke swimming movements. Twelve male swimmers with average age of 17.42 and 6.83 years' of training were examined. Experiments were conducted twice using balance order method to examine swimmers' dynamic rehabilitation of both double-arm and single-arm's breaststroke swimming actions on blood lactic acid exclusion and athletes' performance. The dynamic rehabilitation experiment included several procedures: first, based on the best performance of double-arm and single-arm swimmers' 100 meters breaststroke swimming records timed 1.65 as rehabilitation speed in seconds; then both swimmers conducted 100 meters full-speed swimming, and finally, researchers examined both double-arm, single-arm breaststroke swimming actions for 20 minutes on dynamic rehabilitation. One minute and three minutes respectively after restarting dynamic rehabilitation experiment, researchers tested and recorded the swimmers' LAC and heart rate. There was a 24-hour interval in between each experiment. Swimmers rested one hour after the experiment, and then made 200 meters breaststroke full-speed swimming. Again, researchers tested swimmers' LAC, heart rate, and their performance. The results showed that double-arm swimmers' LAC was significantly better than single-arm swimmers in both one minute and three minutes tests; in 200 meters breaststroke full-speed swimming, double-arm swimmers' performance was significantly better single-arms. The findings showed that dynamic rehabilitation could reduce the swimmers' heart rate, and help their LAC exclusion especially for double-arm breaststroke swimmers.
