How to use this page
This note summarizes one study record. Check the participants, methods, results, and limitations before applying it to training.
- • Design signal: systematic review / meta-analysis.
- • Population relevance: athlete/trained context.
- • Consistency: synthesis evidence present.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.
ELI5
In plain language
This study reviewed systematically the effects of sleep extension on sports performance. (systematic review / meta-analysis; athletes).
In this systematic review / meta-analysis, the abstract suggests a positive relationship with Sleep quality. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: This study reviewed systematically the effects of sleep extension on sports performance.
- • In this systematic review / meta-analysis, the abstract suggests a positive relationship with Sleep quality.
- • Population: athletes.
- • Protocol cues (title/abstract): 106 min.
Protocol
Protocol (as reported)
- • Intervention/exposure: sleep extension.
- • Dose/time/duration cues in abstract/title: 106 min.
- • Outcomes: Sleep quality, Recovery speed.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it may help, and who should be cautious
Who it helps
- • Athletes similar to the study population (athletes) working on sleep.
- • Athletes who can measure Sleep quality, Recovery speed with a repeatable workout or time-trial effort.
Who should be cautious
- • If you have symptoms or conditions that make the intervention risky, get professional guidance.
- • If you’re near race day and can’t safely test, defer the experiment.
Methods
What the study actually did
- • Design: systematic review / meta-analysis.

Results excerpt
What the abstract reports
“The studies used different strategies to extend time in bed or total sleep time (extending 26-106 min).”
Note: excerpts are short; for full context, read the paper.
Limits
Limitations and bias
- • Abstract-only summaries can miss critical details (population, protocol, adherence, and context).
- • Reviews and consensus statements mix protocols and populations; recommendations may not match your exact constraints.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
