基于加速度信号的纵跳力学参数计算
Calculation of Longitudinal Jump Parameters Based on Acceleration Signals
摘要
Abstract
Objective Using the acceleration sensor signals to calculate the off-ground speed and height of the vertical jump and to make regression analysis of its height and the explosive force. Methods The experimenter was required to wear an explosive force tester and an instrument containing an acceleration sensor module andvertically jump 10 times. The off-ground speed, height, explosive force and acceleration signals were recorded during the vertical jump process. Then, the acceleration signal integral was adopted to calculate the off-ground speed and duration of passage;the height of vertical jump and its nonlinear fitting explosive force were calculated by using the time-domain integral. Results The integral method produced a 5.9% error in calculation of the off-round speed; while, the time-domain integral method produced a 8.2% error versus the jump method’s 14.0% in calculation of the height of jumping. Through regression analysis of the height and the explosive force of the vertical jump, the error of the regression model was 6.2%. Conclusion Using the sensor signal of the acceleration sensor to calculate and ift body animation parameters can be used to detect human motion or provide certain reference for the design of monitoring equipment of daily exercise.关键词
