目的是调查(A)在使用加速度计(CSA，WAM 7164)评估体力活动时，五种不同的时间采样间隔(时段设置)对不同强度水平的影响，以及(B)监视器的放置(在臀部和背部)是否会影响结果。对16名7岁儿童进行了连续四天的监测。显著的主要纪元效应被发现花费在非常高的时间(p
The aim was to investigate (a) the effect of five different time sampling intervals (epoch settings) on different intensity levels when assessing physical activity with an accelerometer (CSA, WAM 7164), and (b) whether the placement of the monitor (on the hip and back) would affect the outcome. Sixteen children (aged 7 yrs) were monitored for four consecutive days. A significant main epoch effect was found for time spent at very high (p
