ABSTRACT This study aimed to investigate the temporal relationships between accelerometer‐derived physical activity metrics—specifically volume, intensity, and timing—with the preceding and subsequent nights' sleep in preschool‐aged children. This analysis used the baseline data from a randomised controlled trial among 93 children (53 boys) aged 3–5.9 years who provided daily, repeated measures for at least four days. Open‐source R package GGIR was used to generate daily measures of average acceleration, intensity…
