摘　　要：用加速度传感器测量自行车运动能耗,结果显示:佩戴在脚踝处的加速度传感器记录的各个方向的counts平均值明显大于佩戴在腰部的counts平均值(P<0.05);运用FreedsonVM3计算模型计算的腰部预测MET平均值显著低于标准MET平均值(P<0.05),而脚踝部预测MET平均值则显著大于标准MET平均值(P<0.05);本研究推导的模型计算的预测MET平均值与标准MET平均值基本一致,没有显著性差异。The acceleration sensor was used to test energy consumption of cycling. The test results showed that the average counts of various directions recorded by the acceleration sensor worn on the ankle are more than those recorded on the waist （P〈0.05）. The waist MET average calculated by the FreedsonVM3 is less than the standard MET average（P〈0.05）. The ankle MET average is more than the standard MET average（P〈0.05）. There is no significant difference between the MET average calculated with the model induced by the research and the standard MET average.
