摘要:

文题释义:
运动剂量效应:运动方案必须有足够的强度(体力消耗)、一定的持续时间(进行运动的时间长度)和频率(进行的运动次数),从而使身体在适应运动负荷的过程中逐步提高功能水平。运动的强度及时间、频率可以类比为药物的每次用量、每日用药次数,从而将运动当作一味“药剂”,因此,运动可能会像药物一样对病症具有一定的剂量效应。
阿尔茨海默症:是一种慢性神经退行性疾病,其主要特征表现为认知功能的逐渐衰退,其发病机制尚不完全清楚,包括多种病理性变化,如与患病风险相关基因的相互作用,以及行为或环境的影响等,使得人们难以找到成功的治疗方法。

背景:大量研究认为,运动可以起到改善阿尔茨海默症小鼠病程的作用,但是也有部分研究持不同观点,而运动是否与改善阿尔茨海默症小鼠病程之间存在一定的剂量关系,目前还没有明确的结论。
目的:评估运动与改善阿尔茨海默症小鼠病程之间的剂量效应,并得出较为明确的运动剂量阈值。
方法:以英文检索词“exercise,running,Alzheimer’s disease,AD,mice”及中文检索词“运动,阿尔茨海默,小鼠,老年痴呆”分别检索Web of Science(核心合集)、PubMed、CNKI等数据库,获取相关研究文献,并对其进行研究,然后按照一定逻辑进行分析和综述。
结果与结论:运动与改善阿尔茨海默症小鼠病程之间存在一定的剂量效应。自主转轮运动的运动剂量可能为平均速度大于2.5 m/min,频率为7 d/周,持续时间每天不低于12 h,总持续时间不低于3周时,阿尔茨海默症小鼠的病程才有可能得到改善;跑台运动的运动剂量可能为速度大于10 m/min,频率不低于5 d/周,持续时间不低于9周时,阿尔茨海默症小鼠的病程才有可能得到改善。但是,想要更好地确定运动的剂量效应及其阈值,仍然还有很多的工作要做。

Abstract: BACKGROUND: A large number of studies believe that exercise can ameliorate the disease course of Alzheimer’s disease mice, but some studies hold different views. It is unclear whether there is a certain dose relationship between exercise and the improvement of the disease course in Alzheimer’s disease mice.
OBJECTIVE: To evaluate the dose-effect relationship between exercise and improvement of the disease course in Alzheimer’s disease mice, and to obtain a relatively definite exercise dose threshold.
METHODS: Web of Science Core Collection, PubMed, and CNKI were searched for relevant literature using the keywords of “exercise; running; Alzheimer’s diseases; AD; mice” in English and Chinese, respectively. Then the included literature were logically analyzed and reviewed. 
RESULTS AND CONCLUSION: There was a certain dose-effect relationship between exercise and improvement of disease course in Alzheimer’s disease mice. The disease course of Alzheimer’s disease mice could be improved only when the average speed of voluntary wheel running was greater than 2.5 m/min, no less than 12 hours a day, 7 days per week, for no less than 3 continuous weeks in total as well as when the speed of treadmill running was more than 10 m/min, no less than 5 days per week, for no less than 9 weeks. However, there is still a lot of work to be done to better determine the dose effect of exercise and its threshold.
