研究了小型猪12个月跑步运动后的指屈肌腱。使用一种新开发的方法，肌腱物质和肌腱-骨复合材料的性能同时测量，它被发现，训练增强肌腱插入部位的强度，但对肌腱物质的影响很小。生化分析还表明，肌腱物质中的胶原蛋白浓度在运动后保持不变。还存在中度但不显著的肌腱肥大。目前关于屈肌腱的结果与之前获得的猪指伸肌结果不同[6]。这种对功能性应激反应的差异可能归因于这些组织的生化组成和机械性质。
The digital flexor tendons of the miniature swine were studied after 12 mo of running exercise. Using a newly developed methodology whereby the properties of tendon substance and tendon-bone composite are measured simultaneously, it was found that training augments the strength of the tendon insertion site, but has minimal effect on the tendon substance. Biochemical analyses also showed that the collagen concentration in the tendon substance remains unchanged following exercise. There was also moderate, but not significant, tendon hypertrophy. The present results on flexor tendon differ from those previously obtained for the swine digital extensors [6]. Such difference in response to functional stress may be attributed to the biochemical composition and mechanical properties of these tissues.
