| 摘 要： | 研究目的：探讨风味嗜好学习与睡眠剥夺之间的内在机制，了解风味嗜好学习作为一种促进恢复的手段对提高睡眠质量的作用。研究方法：模拟运动性失眠状态，建立睡眠剥夺模型；观察风味嗜好学习对睡眠剥夺大鼠下丘脑β-内啡肽表达的影响。研究结果：风味嗜好学习建立后，各组大鼠Pa、SO核团内β-内啡肽表达水平显著升高，P〈0．01；睡眠剥夺组大鼠相关核团内阻内啡肽表达水平显著降低，P〈0．01；而嗜好学习后睡眠剥夺组大鼠β-内啡肽表达水平则无显著性变化。研究结论：对运动员进行膳食、睡眠及生活环境等各方面的条件性风味刺激，建立风味嗜好，升高阻内啡肽表达水平是舒缓紧张、焦虑情绪，消除疲劳、促进恢复，避免或缓解运动性失眠发生的有效手段。

| Abstract: | Purpose： To investigate the inner mechanism between flavor preference learning and sleep deprivation （SD）, we want to explore the effect of improving sleep quality by using flavor preference learning as a method to promote recovery. Methods ： We set up sleep deprivation model to simulate exercise insomnia, and observed the influence of flavor preference learning on the expression of β-endorphin in SD rats. Results： The expression of β-endorphin in hypothalamic PA, SO nucleus increased significantly by establishing flavor preference learning, P 〈 0.01 ; but the positive cells decreased in SD group, P 〈 0.01 ; there were no significant changes of β-endorphin＇ s expression in SD after preference learning group. Conclusions： we can establish flavor preference learning based on the athletes diet, sleep, and living conditions in all aspects stimulus, so as to increase the expression of β-endorphin, which may be effective means to ease tension and anxiety, eliminate fatigue, promote recovery, avoid or mitigate exercise insomnia. |
