我们研究了通过废用后肢对大鼠跟腱胶原纤维的影响。随着废用，体质量下降28%，比目鱼肌质量下降20%。与对照组相比，在实验组中观察到表面积和直径减小。胶原纤维的直方图显示实验组中粗纤维减少。实验组胶原纤维的最大表面积仅为对照组的43%。这些结果表明，跟腱的胶原纤维的厚度减少，通过废用。这似乎表明，对紧张的抵抗力因不用而降低。
We examined the influence exerted, through disuse of the hindlimb, on the collagen fibres of the achilles tendon in rats. With disuse the body mass decreased by 28%, and the mass of soleus muscle decreased by 20%. A decrease in the surface area and diameter was observed in the experimental group when compared to the control group. A histogram of the collagen fibres showed a decrease of the thick fibres in the experimental group. The maximum surface area of collagen fibres in the experimental group was seen to be only 43% of that of the control group. These results showed a decrease in the thickness of the collagen fibres of the achilles tendon through disuse. This seemed to suggest that resistance to tension is decreased by disuse.
