| 中文摘要: |
| 探讨高温环境下运动中，口服咖啡因对男大学生运动员运动中唾液分泌型免疫球蛋白A（sIgA）和溶菌酶（lysozyme，LZM）的影响。采用实验研究方法，以13名男性耐力性项目大学生运动员为研究对象。每名研究对象在温度为33℃、相对湿度为65%的实验室完成两次实验（咖啡因运动实验和对照运动实验）。每次实验中，采集运动前60 min、运动前即刻、运动20 min、运动结束即刻的唾液样本，测定唾液sIgA、LZM的浓度。实验结果显示，口服咖啡因对高温环境下耐力大学生运动员运动中唾液sIgA无影响，但会降低唾液LZM水平，高温环境、中等强度运动使男耐力大学生运动员唾液sIgA和LZM的水平升高。 |

| The objective of this study is to examine the effects of oral administration of caffeine on the salivary secretory immunoglobulin A (slgA) and lysozyme (LZM) of male collegiate endurance athletes during exercise in high-temperature environment. The method of experimental study was used and thirteen male collegiate endurance athletes were taken as the subjects. Each subject completed two trials of caffeine exercise trial and control exercise trial in a laboratory with the temperature of 33℃ and the relative humidity of 65%. During each trial, saliva samples were collected at the points of 60min before exercise, immediately before exercise, 20min after the start of the exercise and immediately after exercise. The concentration of salivary sIgA and LZM were determined and secretion rates of sIgA and LZM were calculated. The result shows that oral administration of caffeine does not affect the level of salivary sIgA of collegiate endurance athletes during the exercise in high-temperature environment, but decreases the level of salivary LZM. And the medium intensity exercise in high temperature environment results in the increase of the concentration of salivary sIgA and LZM of male collegiate endurance athletes. |
