呼吸肌的肌力及肌耐力影響人體肺活量與活力，藉由呼吸訓練有助於放鬆胸部肌肉、擴張肺部，改善呼吸肌群的肌力和耐力，長期練習將有助於換氣效率及換氣閾值，提升心肺適能。近年眾多的研究指出，藉由呼吸肌訓練器，對運動員的運動表現有所助益。由於呼吸肌訓練器操作簡易、安全，可於居家使用或臨床訓練，對於體弱、肥胖、心肺呼吸及代謝功能異常等族群，若能妥善的應用於促進自主性呼吸效能或輔助醫療照護，應能達到減緩疾病惡化及健康促進之目標。本研究主要以文獻回顧，探討呼吸肌訓練的健康效益。

Respiratory muscle strength and endurance affect the human lung vital capacity and vitality, by breathing training helps to relieve the chest muscles, dilate the lungs, improve the muscle strength and endurance of the respiratory muscles, long-term practice is bound to increase ventilation efficiency, ventilation threshold, help improve cardiopulmonary fitness. Recently, the emerging popular respiratory muscle training devices to help athletes, many of the literature to confirm the respiratory muscle training can enhance the performance of the movement. As the respiratory muscle training device is simple, safe, can be used at home or clinical training at any time, for frail, obese or cardiopulmonary respiration, metabolic abnormalities and other ethnic groups, if properly applied to promote autonomic respiratory performance or auxiliary medical care should be able to achieve the goal of preventing disease progression and health promotion. In this study, the health benefits of respiratory muscle training were discussed in a literature review.
