摘要
目的探究足球运动员正常行走步态支撑期各时相的特征。方法应用足底压力测试系统测试足球运动员和大学生正常行走的步态周期,对二者同侧脚和左右脚的步态支撑期各时相特征进行比较分析。结果大学生整足接触阶段时间明显大于足球运动员(P<0.05),足球运动员的离地阶段时间所占比例明显大于正常大学生(P<0.05),且足球运动员左脚和右脚的整足接触阶段时间所占比例明显小于正常大学生(P<0.05)。结论足球运动员长期训练下造成支撑期各时相时间值所占比例发生变化,即整足接触阶段时间减少,离地阶段时间增加,这种改变有利于足球运动员对前足的保护,减少前足的损伤。通过分析各时相时间值的变化可以判别足球运动员损伤的程度及损伤后恢复的情况。因此,足底各时相的分析在预防足球运动员足踝损伤方面有一定临床价值。
Objective To discuss the characteristics of the time phases during the gait support period of normal walking of football players. Method To apply foot pressure measurement device to measure the gait cycles of normal walking of football players and college students, and compare and analyze the time phases of gait support period of the same foot and both feet of the two. Results The time of whole foot on the ground of average college students was markedly longer than that of the football players （P〈0.05）. The time proportion of foot aloof from the ground of the football players was markedly more than that of the average college students （P〈0.05）. The time proportion of whole foot on the ground of the both feet of the football players was markedly less than that of the average college students （P〈0.05）. Conclusion Long training of football players causes changes in the pro- portions of time phases of the gait support period, which are shown as a decrease of the time of the phase of whole foot on the ground and an increase of the time of the phase of foot aloof from the ground. These changes are conducive to the protection of front foot of the football players and will lessen any damage to the front foot. An analysis of the changes of time phases can help ascertain the degree of injuries of football players and the state of post-injury recuperation. Thus the analysis of foot time phases has certain clinical value on the prevention of an- kle injuries of football players.
