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: review.
- • Population relevance: athlete/trained context.
- • Consistency: single-study evidence.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.
ELI5
In plain language
The recognition that sleep is one of the foundations of athlete performance is increasing both in the elite athlete arena as well as applied performance research. (review; elite athletes).
In this review, the abstract suggests a positive relationship with Sleep quality, Recovery speed. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: The recognition that sleep is one of the foundations of athlete performance is increasing both in the elite athlete arena as well as applied performance research.
- • In this review, the abstract suggests a positive relationship with Sleep quality, Recovery speed.
- • Population: elite athletes.
- • Protocol cues: abstract may omit dose/timing; use the full paper to replicate accurately.
Protocol
Protocol (as reported)
- • Intervention/exposure: sleep extension, sleep deprivation.
- • Dose/time/duration: abstract doesn’t include enough detail; use the full paper’s methods section.
- • 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 (elite 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: review.
- • Population: elite athletes.
- • Outcomes measured: Sleep quality, Recovery speed.
- • Source: PubMed PMID 29031461 (2017) — Progress in brain research.
Results excerpt
What the abstract reports
“This is likely the result on training times, competition stress/anxiety, muscle soreness, caffeine use, and travel.”
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.
