摘要
30名大学生运动员穿着两款不同鞋底设计(气垫夹层和纯EVA材质)的运动鞋后,进行双臂固定原地纵跳和站立式原地起跑两个原地起动动作,研究采用Kistler牌的三维测力台和Quattro Jump纵跳台,测量分析他们的纵跳高度和起跑时间。研究发现:30名运动员穿鞋底气垫夹层运动鞋时,双臂固定原地纵跳的腾起高度平均值51.73cm,站立式原地起跑的平均时间0.342s;穿鞋底纯EVA材质运动鞋时,双臂固定原地纵跳的腾起高度平均值52.20cm,站立式原地起跑平均时间0.339s。结果表明:被试穿鞋底气垫夹层运动鞋时,其纵跳高度和起跑时间的均值稍低于他们穿鞋底纯EVA材质运动鞋,但差异不显著。由此,可以认为这两款运动鞋不同的鞋底设计并不能给运动员原地起动动作带来差异显著的力学影响。
The researcher measured the jump height and get off time of start actions（vertical jump start and run start） of 30 male college students,who weared air-sole shoes and EVA-sole shoes by Kistler Quattro Jump Plate and Kistler force plate. Results：When they wearing air-sole shoes, the results were 51.73cm high in vertical jump and 0. 342s in mean run start time. When they wearing EVA-sole shoes, the results were 52. 20cm and 0. 339s. EVA-sole shoes appeared performing better than air-sole shoes, but the difference was not significant in statistical analysis. Therefore, these two sole designs bring them the same mechanical impact.
