【摘要】：目的:研究长期高强度有氧训练对雄性大鼠跟腱粘弹性的影响。方法:选择雄性大鼠80只作为研究对象,随机将其划分成一次性跑台运动对照组、一次性跑台运动组、长期运动组和长期运动对照组,按照分组进行相应的训练。结果:一次性跑台运动对照组大鼠跟键组织主要由按顺应力方向排列整齐、结构致密的胶原纤维组成,胶原原纤维存在典型周期性横纹。一次性跑台运动组大鼠跟键局部胶原纤维之间的间隔变大,局部排列错乱。长期运动组大鼠跟腱组织胶原纤维排列较规则,粗细均匀,胶原纤维排列紧密。长期运动对照组大鼠胶原纤维排列紊乱,粗细不均,有部分出现断裂,胶原纤维较少。长期运动组大鼠刚度和最大载荷非常显著性高于长期运动对照组大鼠(P0.01),能量吸收显著高于长期运动对照组大鼠(P0.05)。一次性跑台运动组与一次性跑台运动对照组跟腱水含量、跟腱重量、羟脯氨酸无显著性差异(P0.05);长期运动组大鼠跟腱水含量、跟腱重量、羟脯氨酸与长期运动对照组大鼠相比无显著性差异(P0.05)。一次性跑台运动组PⅠNP显著高于一次性跑台运动对照组(P0.05),PⅢNP非常显著性高于一次性跑台运动对照组(P0.01)。长期运动组PⅠNP和colⅠα1非常显著性高于长期运动对照组(P0.01)。结论:长期高强度有氧训练能够增强雄性大鼠跟腱粘弹性。
[Abstract]:Objective:To study the effect of long-term high intensity aerobic training on the viscoelasticity of Achilles tendon in male rats.Methods:Eighty male rats were randomly divided into one-off treadmill exercise control group,one-off treadmill exercise group,long-term exercise group and long-term exercise control group. In the treadmill exercise group, the collagen fibers of the Achilles tendon tissue were arranged in accordance with the direction of compliance. The collagen fibers of the Achilles tendon tissue in the long-term exercise group were arranged in disorder. The collagen fibers in the long-term exercise control group were disordered, uneven in thickness, some of them were broken, and the collagen fibers were less. The stiffness and maximum load of the long-term exercise group were significantly higher than that of the long-term exercise control group (P 0.01), and the energy absorption was significantly higher than that of the long-term exercise control group (P 0.01). Rats (P 0.05). Achilles tendon water content, Achilles tendon weight and hydroxyproline in the disposable treadmill exercise group and the disposable treadmill exercise control group had no significant difference (P 0.05); Achilles tendon water content, Achilles tendon weight, hydroxyproline in the long-term exercise group had no significant difference (P 0.05) compared with the long-term exercise control group. P III NP in the long-term exercise group was significantly higher than that in the long-term exercise group (P 0.01). Conclusion: Long-term high intensity aerobic training can enhance the viscoelasticity of Achilles tendon in male rats.
