Effects of Natural Between-Days Variation in Sleep on Elite Athletes' Psychomotor Vigilance and Sport-Specific Measures of Performance.
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: controlled study.
- • 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
Performance capacity in athletes depends on the ability to recover from past exercise. (controlled study; elite athletes).
The abstract reports an association involving Sleep quality (not necessarily causation). Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: Performance capacity in athletes depends on the ability to recover from past exercise.
- • The abstract reports an association involving Sleep quality (not necessarily causation).
- • Population: elite athletes.
- • Protocol cues (title/abstract): 05 hours • 57 minutes.
Protocol
Protocol (as reported)
- • Intervention/exposure: sleep extension, sleep deprivation.
- • Dose/time/duration cues in abstract/title: 05 hours • 57 minutes.
- • 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: controlled study.
- • Population: elite athletes.
- • Outcomes measured: Sleep quality, Recovery speed.
- • Protocol cues mentioned: 05 hours • 57 minutes.
- • Source: PubMed PMID 30479518 (2018) — Journal of sports science & medicine.
Results excerpt
What the abstract reports
“Longer TSTs were associated with faster reaction times (p = 0.04).”
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).
- • Single studies often don’t generalize to your event, history, and training load; treat results as a starting point.
- • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
- • This is performance information, not medical advice.
