Abstract

Force platforms are the most commonly used sensory instrument used in the measurement of ground reaction forces for sports biomechanical evaluation. This paper documents the development and validation of such a force platform to be used by national level athletes. The developed force platform consists of four load cells, and an aluminium plate of dimensions 70.6cm × 70.6cm. The data acquired can be monitored on a graphical user interface. Nine segments of the force platform was evaluated at two separate loads to determine regional dependencies. The maximum difference in measurements between segments was 0.6% for the higher load. The force platform was compared against a commercially available force platform, for its ability to accurately measure loads up to 5000N. The developed platform performed better in comparison, when measuring forces above 1000N. The developed force platform is not regionally dependent, and is able to measure ground reaction forces up to 5000N at a sampling rate of 1000Hz, with an accuracy of above 99% between 1000N and 5000N.

国家运动员地面反作用力测量平台的研制与验证

力台是测量运动生物力学评价中地面反作用力最常用的传感仪器。本文记录了这种供国家级运动员使用的力量平台的开发和验证。开发的力平台由四个测力元件和一块尺寸为70.6cm × 70.6cm的铝板组成。采集的数据可以在图形用户界面上进行监控。在两个单独的载荷下，对力平台的九个部分进行了评估，以确定区域依赖性。对于较高的负载，段之间测量的最大差异为0.6%。该力平台与市售力平台进行了比较，因为它能够精确测量高达5000N的载荷。相比之下，所开发的平台在测量1000N以上的力时表现更好。开发的力平台不依赖于区域，能够以1000Hz的采样率测量高达5000N的地面反作用力，在1000N和5000N之间的精度超过99%。
