動態核心運動對呼吸肌訓練效果之探討

The benefits of dynamic core exercise for respiratory muscle training

呼吸肌訓練是臨床診斷與醫療廣為採用的方法，呼吸肌功能也是影響運動表現的因素之一，尤其耐力型運動項目。因此除臨床外，呼吸肌訓練逐漸成為提升運動表現的方法，並以特製器材進行。不過，由於呼吸肌位於支撐人體的核心部位，進行核心相關的阻力運動所產生的腹內壓，能刺激橫隔膜達到訓練適應，是一種以非吸吐方式 （nonrespiratory maneuver） 進行的呼吸肌訓練，且減少特製器材訓練可能引起的不適感。本文針對非吸吐方式訓練呼吸肌的影響，以及相關生理機制，透過資料庫整理相關文獻，歸納以產生65% 橫膈壓，利用腹橫肌、腹內斜肌為主的動作，是非吸吐方式刺激呼吸肌，達到最佳訓練效果的處方。

Respiratory muscle training (RMT) is a practice widely applied in the clinical diagnosis and medical fields. Moreover, the respiratory muscle function is also one of the factors affecting sport performance, especially in endurance sports. Thus, RMT conducted using specialized equipment became an effective method to improve performance. However, the body requires a period of adjustment to the training since the respiratory muscle is located near the human core, which leads to induced intra-abdominal pressure that stimulates the diaphragm during core exercises. Alternatively, nonrespiratory maneuvers may reduce the discomfort associated with such training. This paper focuses on the impacts of nonrespiratory maneuvers on RMT and related physiological mechanisms, including a search through databases for similar studies, to conclude that optimal results can be achieved by nonrespiratory RMT when exercises center on the transverse abdominal muscle, internal oblique abdominal muscle to produce a 65% transdiaphragmatic pressure.
