摘要
目的探讨智能化可穿戴式能耗分析仪(IDEEA)在南京市成年人夜间行为能耗测定中的准确度。方法共选取受试者120人,佩戴IDEEA进入能量代谢舱进行11h的能耗测试,在此期间完成特定的活动。结果能耗结果进行配对样本T检验,结果显示MC(能量代谢舱)与IDEEA所测得的能耗结果存在显著性差异,但是绝对误差在5%左右。结论 IDEEA测量能耗误差率在可以接受的范围内,它提供了一个估算能耗的替代方法。所提供即时和累积的能耗数据可以用来估测一段时间范围内的人体活动能耗。
Objective To investigate the accuracy of intelligent device for energy expenditure and activity(IDEEA) in the measurement of energy consumption in the evening of adults in Nanjing. Methods 120 subjects were selected, and worn IDEEA into the metabolic chamber(MC) for 11 hours of energy consumption test. Results Energy consumption results were tested an independent sample t-test.The results showed no significant difference between MC and IDEEA.The absolute error rate of energy consumption measurement was about 5%. Conclusion Energy measurement of IDEEA absolute error rate is within acceptable range, and it provide a high-precision alternative method for estimating energy consumption. The immediate and cumulative energy consumption data can be used to estimate the energy consumption for human physical activities over a period of time.
