It had been proved by many studies that the energy expenditure and training intensity could be assessed by the integral of acceleration amplitude of physical activity . this method has been considered to be the most potential method for the assessment of physical activity 大量的研究表明,使用人體運動過程中的加速度向量幅值對時間的積分,可以較好的估計運動的能耗,進(jìn)而可以估計運動量和運動強(qiáng)度,使用加速度傳感器估計運動量的方法是目前公認(rèn)的最有前途的估計方法。
