| 摘要: | 目的：本研究旨在探討大專划船選手在高強度間歇訓練與中強度持續訓練對下肢各肌肉活化之差異。方法：本研究以大專划船運動員為研究對象，共招募了17名男性受試者（年齡17.6±1.4歲，身高176.6±4.7公分，體重75.4±12.6公斤，船齡3.2±2.1年），受試者將在陸上划船測功儀上盡全力划船2000公尺，並記錄平均功率和平均槳頻。接著，將這些數據當作基準線，用於後續的研究分析。再讓受試者下肢肌肉黏貼肌電圖感測器後，進行中強度持續訓練，經休息30分鐘後，隨即再進行高強度間歇訓練。每位受試者均收集兩種訓練模式下七條肌肉的肌電圖訊號，以相依樣本t考驗檢定在高強度間歇訓練和中強度持續訓練之間的差異性在進行統計分析時，所有的顯著水準皆訂為α=.05。結果：在高強度間歇訓練與中強度持續訓練之間，臀大肌拉槳、腿後腱拉槳及回槳、股直肌拉槳及回槳、股外側肌拉槳及回槳、股內側肌拉槳及回槳、脛骨前肌拉槳、腓腸肌拉槳及回槳均呈現顯著差異。結論：根據研究結果，高強度間歇訓練相較於中強度持續訓練對下肢肌群是較為有效益的訓練方式，高強度間歇訓練可以顯著提高下肢肌群的活化程度。這些發現將對運動訓練和肌肉活化提供參考。然而，為了進一步確認這些結果的普遍性和長期效果，仍需要更多的研究和探索。
Objective: This study aimed to utilize surface electromyography (EMG) to elucidate the discrepancy in lower limb muscle activation between high-intensity interval training and moderate-intensity continuous training for collegiate rowers. Method: Seventeen male collegiate rowers (age 17.6±1.4 years, height 176.6±4.7 cm, weight 75.4±12.6 kg, rowing experience 3.2±2.1 years) were recruited as participants. They were instructed to exert maximal effort while rowing 2000 meters on a land rowing ergometer. Baseline data were established by recording average power and average paddle frequency. EMG sensors were affixed to seven lower extremity muscles of each participant. High-intensity interval training and moderate-intensity continuous training were performed with a 30-minute rest period between sessions. Paired sample t-tests were conducted to assess differences between high-intensity interval training and moderate-intensity continuous training with a significance level set at α = .05. Results: Significant differences were observed in the following muscles between high-intensity interval training and moderate-intensity continuous training: gluteus maximus (catch), hamstrings (catch and recovery), rectus femoris (catch and recovery), vastus lateralis (catch and recovery), vastus medialis (pull and recovery), tibialis anterior (catch), and gastrocnemius (catch and recovery). Conclusion: The findings suggest that high-intensity interval training is more effective than moderate-intensity continuous training for activating lower limb muscle groups among collegiate rowers. High-intensity interval training notably enhances lower limb muscle group activation. These results provide valuable insights for sports training and muscle activation optimization. However, further research and exploration are warranted to validate the generalizability and long-term implications of these findings. |
