本研究的目的是在一组女性中确定ActivPAL（TM）体力活动记录仪的代谢当量（MET）方程和步频函数的有效性。使用标准的跑步机协议，62名15-25岁的女性在跑步机上以3.2至7.0 km的速度行走。h（1）佩戴ActivPAL时。在每种速度下使用呼气分析测量氧气消耗量，并根据每个参与者自己的静息代谢率估计每种速度的MET。18名参与者的子集也佩戴了Activograph。结果表明，ActivPAL中的内置方程显著低估（P
The purpose of this study was to determine the validity of the metabolic equivalent (MET) equation and step rate function of the ActivPAL (TM) physical activity logger in a group of females. Using a standard treadmill protocol, 62 females aged 15-25 years walked on a treadmill at speeds between 3.2 and 7.0 km . h (1) while wearing an ActivPAL. Oxygen consumption was measured using expired gas analysis at each speed and METs for each speed were estimated based on each participant's own resting metabolic rate. A sub-set of 18 participants also wore an Actigraph. Results showed that the in-built equation in the ActivPAL significantly underestimated (P
