| 摘 要： | 柠檬酸钠对运动能力的影响尚存争议,柠檬酸钠对耐力运动能力影响的研究也较少。采用双盲交叉设计比较了20名少年男子耐力运动员补充0.6g/kg体重剂量的柠檬酸钠1小时后完成5000米跑的运动成绩,并测试运动前后血液离子浓度变化。结果显示,服用柠檬酸钠对运动成绩有显著提升,并且补充柠檬酸钠可以使安静及运动后血液钾及钙离子浓度显著下降。

| Abstract: | The effect sodium citrate ingestion had on blood ions level before and after 5000m run was examined.20 junior endurance male athletes completed two 5000m trials.The trials were double-blind and randomly assigned for sodium citrate(0.6g/kg body mass) and for sodium(NaCl,0.1g/kg body mass) one hour before exercise.5000m completion time was measured.Blood samples were collected pre-ingestion,pre-exercise,post-exercise and 10 minutes post-exercise and analyzed for blood ions.The results showed that the athlete ... |
