Abstract

A dynamometer for measurement under static and dynamic conditions is presented. At different load levels, force, velocity, work and power can be measured in explosive leg extensions. Measurements on 53 subjects at different load levels (0-125.5 kg) were carried out. Peak power ranged from 2611 to 1746 W, force from 1351 to 1899 N, velocity from 1.61 to 0.89 m X s-1 and work from 329 to 605 J. Between trial correlation coefficients ranged from 0.72 to 0.95. The dynamometer is compared with others, and it is concluded that data obtained by this dynamometer have a greater practical validity.

摘要

本文介绍了一种用于静态和动态条件下测量的测力计。在不同负荷水平下，可以测量爆发性腿部伸展时的力、速度、功和功率。对53名受试者在不同负荷水平（0 - 125.5千克）下进行了测量。峰值功率范围为2611至1746瓦，力为1351至1899牛，速度为1.61至0.89米×秒⁻¹，功为329至605焦。各试验之间的相关系数范围为0.72至0.95。将该测力计与其他测力计进行了比较，得出的结论是，通过该测力计获得的数据具有更高的实际有效性。
