摘要
本文用X线摄片法研究了35名跳跃运动员和12名大学生的跖骨的横径、骨体骨壁厚度和近节趾骨的横径。发现所测数据跳跃运动员均大于大学生。Ⅱ跖骨骨壁厚度最大,厚度以Ⅱ跖骨为中心,向两侧递减。Ⅱ~V跖骨骨体内侧壁厚度均大于外侧壁。还发现跳跃运动员的跖骨和趾骨均较大学生长,这提示跳跃运动员有较长的足弓,趾骨和跖骨长度与足弓长度有关,较长的跖骨和趾骨有增大足弓的作用,有利于弹跳力的发挥。跖骨和趾骨的长度可作为跳跃运动员选材的一项参考指标。
X-ray films were used to study the diameter and thickness of the bony cor-tex of metatasus and the diameter of phalanges of 35 jumpers and 12 collegestudents. We discovered that the parameters of jumpers were larger than thatof college students. The thickness of bony cortex of Ⅱ metatasus is the greatest. The thickness ofbony cortex decreases medially and laterally from II metatasus. The medial wallof bony cortex of II metatasus is thicker than the external wall. The length ofmetatasus and phalanges could used as a reference in the selection of jumpers.
