Sleep Regularity and Predictors of sleep Efficiency and sleep Duration in Elite Team Sport Athletes

The study analyzed sleep patterns in 203 elite team sport athletes using a novel sleep Regularity Index (SRI). Regular sleepers had more consistent bedtimes and wake-up times, better sleep efficiency, and less variability in sleep duration than irregular sleepers, although total sleep time was similar. Key factors for better sleep efficiency included earlier bedtimes and stable sleep onset times, while later wake-up times supported longer sleep durations. The findings suggest that consistent sleep schedules are critical for maintaining sleep quality, which can impact athletic performance and overall cognitive and physical health.

Maintain consistent bedtimes and wake-up times, even on weekends, to improve sleep quality. Avoid activities that delay sleep onset, like late-night use of devices. For athletes or individuals with intense schedules, prioritize sleep regularity alongside sufficient duration for better performance and recovery. These recommendations stem from objective monitoring of sleep in an elite population, making them highly relevant and applicable.
