广枣提取液对小鼠免疫功能和运动耐力的影响 总被引:11,自引:0,他引:11
观察了广枣提取液对小鼠免疫功能、运动耐力的影响。结果表明:广枣提取液可明显增加小鼠耐缺氧时间,延长小鼠负重游泳时间,降低运动后小鼠血乳酸水平,显著提高其心肌组织中SOD活力;同时明显增加小鼠脾脏/体重、胸腺/体重比值,增强小鼠对巨噬细胞的吞噬能力.提高小鼠的细胞免疫、体液免疫功能。提示广枣提取液具有显著促进小鼠免疫功能及显著提高小鼠运动耐力的功效。 相似文献

Abstract The purpose of the present study was to investigate competitive anxiety during balance beam performance in gymnasts. Competitive anxiety was assessed continuously by heart rate monitoring and by retrospective self-report of nervousness in eight female national level gymnasts during their balance beam routine during one competition and two training sessions. A significant negative correlation was found between the score of the retrospective self-report of nervousness and performance during the routine. There were no significant differences in performance score by the judges between the three test sessions. There were also no differences in the retrospective self-report of nervousness. However, heart rate was significantly higher during the competition session than during the training sessions. The potential value of the retrospective report of nervousness for the study of critical events during gymnastic performance is illustrated. The results are discussed in the light of catastrophe theory. 相似文献
