摘　　要：通过对短跑运动员和非运动员跟腱横截面积和弹性模量的研究后发现,短跑运动员和非运动员相比,跟腱的横截面积无显著性变化,弹性模量则明显增加,其差异有显著性,表明短跑训练后肌腱能够承受更大的应力可能是通过内部结构的改变而不是通过增粗、肥大来实现的。By making a comparative study of the cross-sectional area and modulus of elasticity of the Achilles tendon of sprinters and non-athletes, the authors found that as compared with non-athletes, sprinters＇ Achilles tendon＇s cross-sectional area is not significantly different, but their Achilles tendon＇s modulus of elasticity is significant larger, and the difference is significant, which indicates that the tendon being able to bear greater pressure after sprint training may be realized through the change of the internal structure in stead of though thickening and fattening.
