| 摘 要： | 观察赛艇运动员运动后吸入高氧对乳酸(La)、碳酸氢根离子(HCO3^-)和pH值的影响，实验使用测功仪，在15min内划完4000m的运动负荷，测试吸氧量(VO2)、心率(HR)、血La、血pH值和HCO3^-浓度。结果表明，吸氧组与不吸氧组相比，吸氧组血La、pH值恢复得较快，并在运动后5、10min有显性差异；同样吸氧组HCO3^-恢复得较快，且在运动后20、30min有显性差异。结果提示，运动后吸氧可能改善体内酸性环境，加快乳酸的消除，有助于机体的恢复。

| Abstract: | In order to investigate the effects of hyperoxic inhalation on lactate(La), HCO 3 - and pH after intense exercise. 8 bowing athletes finished 4 000 meter in 15 min on the rowing ergometer. The results showed that removal of lactate ,HCO 3 - and pH in hyperoxic inhalation group were quicker than normal group. Lactate decreased and pH increased significantly in hypeioxic inhalation group compared with that in normal group 5 and 10 min after inhaling oxygen. HCO 3 - of hyperoxic inhalation group increased significantly compare with that in normal group 20 and 30 min after inhaling oxygen. In conclusion, hyperoxic inhalation would be helpful to recovery after intensity exercise. |
