摘要

運動員可以藉由骨骼肌的訓練，提升運動表現。近年來，有研究指出，呼吸肌亦可經由訓練，增進運動員在有氧耐力上的表現。目的：本研究旨在探討經由四週的呼吸肌訓練介入後，對男性鐵人三項運動員之影響。方法：本研究以12位男性鐵人三項選手為受試者（平均年齡29.8±4.13歲，身高173.9±3.34公分、體重67.0±5.74公斤），以隨機方式分配為控制組與實驗組。控制組進行四週，每週3天，每次30分鐘正常自行車訓練台練習（76-90%FTP，迴轉數90-100 rpm），實驗組除了進行正常自行車訓練台練習之外，額外利用呼吸肌訓練器，進行每週5天，每天2次，每次30下之呼吸肌訓練。全體受試者於訓練前後均接受自行車功能閾值功值（function threshold power, FTP）、呼吸肌之阻抗、肌力、肺容積、安靜時心跳率及運動後血乳酸濃度之測試。統計方法以相依樣本t考驗檢定實驗組及控制組前後測差異，再以獨立樣本單因子共變數分析進行檢定，顯著水準定為α=.05。結果：在呼吸肌阻抗、肌力、血乳酸濃度、安靜時心跳率及自行車功能閾值功值上，兩組均未達顯著差異。結論：四週的呼吸肌訓練無法有效提升選手之訓練效果。

Athletes can improve their performance by training skeletal muscle. For the past few years, we can find some researches got the same result: Athletes can improve their aerobic endurance performance by training their inspiratory muscle. Purpose: This research was to investigate the effects of 4 weeks inspiratory muscle training on the function threshold power (FTP) performance of male triathlon athletes. Method: 12 male triathlon athletes were recruited as the subjects. They were randomly assigned to experiment group and control group. The control group athletes did cycling training (76%-90% FTP, 90-100 rpm) for 4 weeks, 3 days per week, 30 minute per time. The experiment group athletes did not only cycling training but also inspiratory muscle training (5 days per week, 2 times per day, 30 breaths per time) for 4 weeks. All subjects received FTP, inspiratory impedance, inspiratory muscle strength, lung volume, heart rate and lactate acid tests respectively before and after the training period. The data was analyzed using independent t-test to examine any changes after training. The statistical significant level is determined at α= .05. Result: There were no significant differences on FTP, inspiratory impedance, inspiratory muscle strength, lung volume, hart rate and lactate acid between the experiment and control group. Conclusion: After 4 weeks inspiratory muscle training, athletes can't increase FTP, inspiratory impedance, inspiratory muscle strength, lung volume, heart rate and lactate acid effectively.
