Both written and verbal sleep hygiene strategy interventions modestly improve sleep-related behaviors in track and field athletes, particularly by encouraging earlier bedtimes and slightly extending total sleep duration.

In a three-arm randomized controlled trial with 66 track and field athletes, both written and verbal sleep hygiene strategy groups showed significant improvements in Sleep Hygiene Index scores from baseline to intervention, compared to a control group. Although no significant differences were found in objective sleep parameters, there was a non-significant trend toward increased total sleep time, primarily due to earlier bedtimes.

Both written and verbal sleep hygiene strategy interventions modestly improve sleep-related behaviors in track and field athletes, particularly by encouraging earlier bedtimes and slightly extending total sleep duration. The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).

The Claim

Both written and verbal sleep hygiene strategy interventions modestly improve sleep-related behaviors in track and field athletes, particularly by encouraging earlier bedtimes and slightly extending total sleep duration.

This conclusion is most relevant to: Track and field athletes competing at regional or national level (N=66).

What the Research Shows

The conclusion draws on 1 linked study. Highlights from the cited literature:

  • Written vs. verbal sleep hygiene strategies administration in track and field athletes: a randomized controlled trial study. (The Journal of sports medicine and physical fitness, 2026) —

How It Works

The proposed biological pathway:

  • Sleep hygiene strategies are provided to athletes in either written or verbal format
  • Athletes implement the strategies in their daily routine
  • Improved sleep-related behaviors (e.g., earlier bedtimes) are adopted
  • Result: Modest improvement in sleep hygiene behaviors and slight increase in total sleep time

Who Might Benefit

Evidence fit by population:

  • Track and field athletes competing at regional or national level (N=66)

Limitations & Caveats

Important context when interpreting this evidence:

  • No significant differences in objective sleep measures were observed, limiting the strength of conclusions
  • The study was conducted over a short period (10-day baseline and 10-day intervention), which may not capture long-term effects
  • The sample was limited to track and field athletes, so results may not generalize to other populations

Frequently Asked Questions

What are sleep hygiene strategies?

Sleep hygiene strategies are practical, evidence-informed recommendations designed to enhance both the quantity and quality of sleep, such as maintaining a consistent sleep schedule and avoiding stimulants before bed.

Did the study find significant improvements in sleep quality?

No significant differences were found in objective sleep parameters, but the Sleep Hygiene Index scores improved significantly in the intervention groups compared to the control group, indicating better sleep-related behaviors.

Which method of delivering sleep hygiene strategies was more effective: written or verbal?

Both written and verbal delivery methods showed similar modest improvements, with no significant difference between them, suggesting both can be effective in promoting sleep-related behavior changes.

What was the main benefit observed in the intervention groups?

The main benefit was a trend toward earlier bedtimes, which contributed to a non-significant increase in total sleep time, indicating that the strategies encouraged better sleep scheduling.
