中文摘要:

从运动员选材角度探讨不同项目足弓形态特点及在跳深实验中足弓形态与支撑时间关系，以期为足弓形态应用于田径运动员选材提供科学依据。研究对象：上海市一、二线短跑和中长跑共84名运动员，其中男子短跑运动员34名，女子短跑运动员19名，男子中长跑运动员21名，女子中长跑10名。方法：所有研究对象均进行身高、体重、足弓形态、跳深实验测试，然后分组研究足弓形态与跳深实验中支撑时间关系。结果：男女均表现出足弓低的组支撑时间快于足弓高的组支撑时间；短跑和中长跑项目中男女优秀组的足弓均出现低于一般组的趋势；短跑男子优秀组和一般组的足弓基本都低于中长跑优秀组和一般组的趋势。结论：足弓高低是影响短跑或中长跑运动员支撑时间长短的重要因素，在运动员选材中或对教练员训练中有重要的指导意义。

英文摘要:

The purpose of the study is to discuss the characteristics of foot-arch of the different sports athletes and the relations between foot-arch and contact time in drop-jump from the viewpoint of talent selection so as to provide scientific reference for using foot-arch in selecting track and field athletes. Subject: A total of 84 athletes of sprint and distance running from shanghai youth and professional teams (34 men and 19 women of sprint, 21 men and 10 women of distance running). Method: All the subjects took the measurement of height, weight and foot-arch and did drop-jump test. Then they were divided into groups for the study of the relations between foot-arch and contact time in drop-jump. Result: The contact time of the low foot-arch groups of both male and female is faster than that of the high foot-arch groups. The foot-arch of the elite male and female athletes of sprint and distance running tends to be lower than that of the ordinary athletes groups. The foot-arch of the elite male sprint group and ordinary group is basically lower than that of the elite distance running group and ordinary group. Conclusion: Foot-arch is an important factor affecting the contact time of the sprint and distance running athletes. It is of great significance in talent selection and training.
