聆聽音樂對不同蹲舉運動強度下重量負荷的影響

Abstract

背景：音樂逐漸被使用在運動訓練或競賽中並被視為能夠增進運動表現。其中，運動強度、運動者的訓練程度及音樂內容的選擇都可能影響音樂的效益。然而，目前尚無研究去探討聆聽音樂對從事不同阻力運動強度時的表現影響，因此需要進一步的釐清。目的：探討在進行不同蹲舉運動強度下，聆聽快節奏自選音樂對重量負荷、向心力量峰值、運動情緒以及RPE數值的影響。方法：本研究採用重複量數與隨機分配的方式，讓12名無阻力訓練經驗的健康男性 (22.4±1.6歲) 在有無聆聽聆聽快節奏自選音樂時 (>120 bpm)，於史密斯儀器上分別進行6RM與15RM蹲舉測驗，並記錄每次測驗之最大重量負荷、RPE數值以及POMS情緒量表。另外，藉由位移計收集槓鈴的位移與時間資料，進一步計算向心收縮階段的力量峰值。以相依樣本t-test考驗在分別進行6RM與15RM蹲舉測驗時，有無聆聽音樂處理下運動表現、運動情緒與RPE數值的差異性。顯著水準定為 p ≤ .05。結果：進行6RM與15RM蹲舉測驗後，最大重量負荷、向心力量峰值、各分項的POMS情緒量表指標以及RPE數值在聆聽自選音樂與聆聽空白音檔處理時無顯著差異。然而，當聆聽音樂進行6RM測驗後，代表整體情緒的心情干擾指標顯著低於聆聽空白音檔，但在進行15RM測驗後，聆聽音樂與否則無顯著差異。結論：聆聽快節奏自選音樂無法增進未受過訓練者在不同蹲舉運動強度下的最大重量負荷與向心力量峰值表現，以及降低運動自覺努力程度；然而，在進行較低運動量的6RM蹲舉測驗時，聆聽音樂能提升運動情緒。Background: Listening to music has been commonly used during exercise training or competition and is considered to help improve exercise performance. However, the exercise intensity, the training background, and the music selection would affect the benefits of music listening. To date, no study has yet examined the effects of music listening on exercise performance at different intensities of resistance exercise. Purpose: To investigate the effects of music listening on squat loads, concentric peak force, exercise’s emotion and RPE values at different intensities. Methods: Twelve non-resistance-trained males (age 22.4±1.6 years) performed 6RM and 15RM squat testing on Smith Machine while listening or not listening to self-selected music (>120 bpm) in a counter-balanced and repeated measures manner. Loading, RPE values, and POMS scales were recorded during each testing. In addition, displacement transducer was used to record displacement of barbell for calculating concentric peak force. A paired samples t test was used to analyze the data. The significance level was set at p ≤ .05. Results: Performing 6RM and 15RM squat testing while listening to self-selected music did not significantly improve squat loads, concentric peak force, POMS scales, and RPE values when compared to no music listening. However, total mood disturbance scores of POMS were significantly decreased while listening to music when performing 6RM testing, but not when performing 15RM testing. Conclusion: Listening to music can’t improve strength performance, concentric peak force, and RPE when performing squat testing at different intensities. However, listening to music can improve emotion during testing at lower exercise volume.
