采用惯性传感技术和无线蓝牙采集技术研制了便携式肌肉等张收缩关节功率曲线测试系统,详细说明了该测试系统的内部结构和数据处理方法。该测试系统采用三次样条插值法插值,能够方便准确的测试不同负重下肌肉等张收缩的最大峰值关节功率曲线,能方便携带到课堂和操场上进行教学和测试,在运动员选材、日常力量训练等多个方面都有非常重要的应用。采用BIODEX等速肌力测试系统对膝关节关节功率进行测试分析,测试结果和本测试系统获得的结果通过配对样本T检验方法,双侧显著性水平大于0.05,提示二者没有显著差异,验证了本系统的数据有效性。

Inertial sensor technology and wireless bluetooth capture technology are adopted to develop the portable test system of isotonic muscle contraction joint power curve. The paper elaborates the internal structure and data processing method of the test system. The test system uses a cubic spline interpolation to interpolate, which make it possible to easily test the peak power curve of isotonic muscle contraction joints under different loads and to be taken into classrooms and training places. It can be widely applied to athletes＇ selection and training.
