我们测试了在健康久坐的人中观察到的呼吸肌训练（RMT）后增加的自行车耐力是否与运动期间训练诱导的心搏量（SV）增加相关，类似于耐力训练的已知效果。13名受试者通过正常二氧化碳呼吸过度接受RMT，9名接受有氧耐力训练（骑自行车和/或跑步），15名作为非训练对照。培训包括40个会议在15周内进行，其中每个会议持续30分钟。70%最大有氧功率（（W）超过点（max））的自行车耐力提高24% [平均（SD）35.6（11.9）min vs 44.2（17.6）min，P
We tested whether the increased cycling endurance observed after respiratory muscle training (RMT) in healthy sedentary humans was associated with a training-induced increase in cardiac stroke volume (SV) during exercise, similar to the known effect of endurance training. Thirteen subjects underwent RMT by normocapnic hyperpnea, nine underwent aerobic endurance training (cycling and/or running) and fifteen served as non-training controls. Training comprised 40 sessions performed within 15 weeks, where each session lasted 30 min. RMT increased. cycling endurance at 70% maximal aerobic power ((W)over dot(max)) by 24% [mean (SD) 35.6 (11.9) min vs 44.2 (17.6) min, P
