摘要

This study aims to explore the effect of respiratory muscle training (RMT) in maximal inspiratory pressure (PI(superscript max)), maximal expiratory pressure (PE(superscript max)), ventilation (VE), oxygen intake (V(superscript O2)), carbon dioxide output (V(superscript CO2)) and heart rate (HR) of swimmers. 20 healthy subjects, aged 18 to 25, were recruited. Each subject had pre- and post-training pulmonary function, respiratory pressure and maximal V(superscript O2) measured. With the pretraining value of maximal V(superscript O2), subjects were assigned to either an experimental group or control group (experimental group: 20.79 ± 3.83 ml/kg/min; control group: 20.42 ± 3.83 ml/kg/min) in a balanced order, and the study was conducted in a single-blinded manner. The experimental group attended 6 weeks (5 days/week; 2 periods/day; 30 times/period) of RRMT while the control group did not attend training. The two groups showed insignificant differences in pre-training PImax. For the experimental group, post-training PImax was significantly higher (92.40 ± 8.18 vs. 99.51 ± 5.18 cmH2O, p ＜ .05) compared with the pre-training value, while PEmax showed insignificant differences in both groups (p ＞ .05). Post-training V(superscript O2) was significantly higher when compared to pre-training value (22.71 ± 4.03 ml/kg/min, p ＜ .05). After 6 weeks of training, HR of experimental group was lower than of control group (122 ± 1.3 vs. 130 ± 1.4 beat/min, p ＜ .05), while HR recovery capacity was higher (72 ± 1.1 vs. 84 ± 1.2 beat/min, p ＜ .05). However, the two groups showed insignificant differences in post-training VE, V(superscript O2) and V(superscript CO2). This study showed that, after 6 weeks of RMT, the improvement of PImax and V(superscript O2)max and decrease of HR were significant.
