This study compared the measurements of total steps and moderate-to-vigorous physical activity (MVPA) between ActiGraph and the Lifecorder and Active Style Pro accelerometers in junior high school students.
The total steps and MVPA significantly differed between ActiGraph and Lifecorder measurements, whereas the intraclass correlation coefficients (ICCs) for total steps and MVPA between the two accelerometers were not significant. There was no significant difference between the total steps measured using ActiGraph and Active Style Pro, and moderate agreement was noted. Additionally, MVPA measured using ActiGraph and Active Style Pro significantly differed, whereas the ICC for MVPA measured using the two accelerometers was not significant. When comparing the total steps between ActiGraph and Lifecorder and MVPA between ActiGraph and Lifecorder or Active Style Pro, it should be noted that the accelerometer measurements are not compatible.
本研究比较了 ActiGraph 和 Lifecorder 及 Active Style Pro 加速度计在初中生中测量的总步数和中高强度体力活动（MVPA）。
ActiGraph 和 Lifecorder 测量的总步数和 MVPA 存在显著差异，而两种加速度计之间总步数和 MVPA 的组内相关系数（ICC）不显著。ActiGraph 和 Active Style Pro 测量的总步数之间无显著差异，存在中度一致性。此外，ActiGraph 和 Active Style Pro 测量的 MVPA 存在显著差异，而两种加速度计测量的 MVPA 的 ICC 不显著。当比较 ActiGraph 和 Lifecorder 之间的总步数以及 ActiGraph 和 Lifecorder 或 Active Style Pro 之间的 MVPA 时，应注意加速度计测量结果不兼容。
