呼氣肌力訓練中調整阻力負荷與張力維持時間的生理適應

// Physiologic Adaptations to Modifying Resistive Load and Time Under Tension During Expiratory Muscle Strength Training

本研究探討呼氣肌力訓練（EMST）中阻力負荷與施力時間（TUT）變化對呼吸動作、肌肉活性及感覺努力度的影響｜20名健康成人在四種不同負荷與TUT條件下接受訓練，並測量呼吸動態、肌肉興奮及努力評分｜結果顯示負荷與TUT顯著影響生理反應，且EMST模式與咳嗽及吞嚥動作相似，暗示可透過調整參數優化訓練效果，並建議進一步長期研究。

// This study examined how changes in resistive load and time under tension (TUT) affect respiratory movements, muscle activity, and perceived effort during expiratory muscle strength training (EMST). Twenty healthy adults performed EMST under four conditions varying load and TUT, with measurements of respiratory kinematics, muscle excitation, and effort ratings. Results showed that load and TUT significantly influenced these physiological responses, while EMST conditions were largely similar to cough and swallowing tasks. The findings suggest tailoring EMST parameters can optimize training effects and specificity, warranting further longitudinal research.
