Abstract

Background

Regular physical activity (PA) benefits sleep, but its timing and adherence to the WHO's 60-minute MVPA guideline can affect sleep, especially in children with ADHD who frequently experience sleep problems. This study examines how exercise timing influences sleep parameters (e.g., sleep latency, sleep efficiency, total sleep time, and wake after sleep onset [WASO]) in children with ADHD.

Methods

This cross-sectional study included 229 children with ADHD (Mage=8.61 ± 1.30, 80.3% boys). PA timing was categorized as more than 8 hours before bedtime, 3–8 hours before, and less than 3 hours before. MVPA guideline attainment was defined as ≥ 60 minutes of MVPA daily. PA and sleep parameters were recorded by an ActiGraph GT9X accelerometer for 7 consecutive days.

Results

Of the 229 children with ADHD, 154 (67.2%) met WHO's 60-minute MVPA guideline. These children had better sleep outcomes than those who didn't meet the guideline, with shorter sleep latency (F=45.39, η²=.172), higher sleep efficiency (F=22.05, η²=.092), and less WASO (F=15.42, η²=.066). MVPA guideline attainment (β=-.290, p=.001) and exercising more than 8 hours before bedtime (β=-.247, p=.005) were linked to reduced sleep latency. Additionally, both meeting the MVPA guideline (β=.299, p=.001) and exercising more than 8 hours before bedtime (β=.272, p=.003) were associated with increased sleep efficiency, while exercising less than 3 hours before bedtime was associated with decreased sleep efficiency (β=-.229, p=.001).

Conclusion

The results emphasize that exercising more than 8 hours before bedtime and meeting the MVPA guideline are crucial for improving sleep in children with ADHD.
