不同训练模式对跟腱末端纤维软骨细胞影响的实验研究

Effects of different training methods on the fibrocartilage of achilles tendon insertion: An experimental study

目的探讨跟腱在不同训练模式下的塑形改建特点,了解跟腱末端纤维软骨细胞功能结构的变化规律,以此对军事训练提出相应的预防措施。方法在特制的兔跑跳装置中,采用不同负荷和时间的训练模式对成年兔进行训练,切取跟腱末端区组织,重点进行含PAS阳性颗粒软骨细胞计数。结果训练的第2周开始,含PAS阳性颗粒的纤维软骨细胞数目随强度的增强而逐步增多,但一旦处于失代偿状态,则将减少。结论过度负荷是跟腱末端病发生的主要原因,推广循环训练法有积极防治作用。

Objective To evaluate Achilles tendon's remodeling character under different training methods, to know the functional and structural changing law of insertion fibrocartilage, and depending on above results to put forward correspondent preventive plans of military training. Methods In special running and jumping equipments, adult rabbits were trained under different load and length of time, insertion tissues were harvested; the PAS positive cells were primarily counted. Results From the second week of training, the number of PAS positive cell increased gradually with the increase of load, but decreased once at decompensable state. Conclusions Excessive load is the major cause of enthesiopathy, and broadening cycling training methods have positive prevention & treatment effects for the disease.
