游泳训练对少儿女生通气功能的影响

摘要

After 1 year of training,some static lung volumes parameters:vital capacity (VC),total lung capacity (TLC)and functional residual capacity (FRC)were significantly larger (P<0.05)in the training group than in the control group; some dynamic lung volumes parameters: 1-s forced expiratory volume(FEV1.0)(P<0.01),maximal expiratory flows at 50%(MEF50)(P<0.05)had increased very significantly in the training group in comparison with the control group,but they were unchanged in the control group. Raw tended to be lower in the girl swimmers and higher in the control group. The results indicate that swimming training improves static and dynamic lung volumes,promotes the conductive properties of both the large and the small airways,facilitates the airways and the alveolar spaces.%经过1年的业余游泳训练后，训练组(n=8)少儿女生的静态肺容量指标：肺活量(VC)、肺总量(TLC)、功能余气量(FRC)较控制组(n=10)显著提高(P<0.05)；动态肺活量指标：1s用力呼气量(FEV1.0)、用力呼出50%肺活量时的最大流速(MEF50)较对照组有了非常显著的提高(P<0.01)，而控制组无明显变化。训练组女生Raw有降低趋势，而控制组却有升高趋势。结果表明，大运动量的游泳训练能增强静态和动态肺容量，提高大气道和小气道的通气能力，调节气道及肺泡腔的建立。
