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: randomized trial.
- • 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
To compare the effects of a single night of sleep extension to an active recovery session (CON) on post-exercise recovery kinetics. (randomized trial; elite athletes).
The abstract doesn’t indicate a clear change in Sleep quality, Recovery speed under the tested conditions. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.
Takeaways
What the abstract suggests
- • Study question: To compare the effects of a single night of sleep extension to an active recovery session (CON) on post-exercise recovery kinetics.
- • The abstract doesn’t indicate a clear change in Sleep quality, Recovery speed under the tested conditions.
- • Population: elite athletes.
- • Protocol cues (title/abstract): 10 hours • 0 hour • 14h • 36h.
Protocol
Protocol (as reported)
- • Intervention/exposure: sleep extension.
- • Dose/time/duration cues in abstract/title: 10 hours • 0 hour • 14h • 36h.
- • 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: randomized trial.
- • Population: elite athletes.
- • Outcomes measured: Sleep quality, Recovery speed.
- • Protocol cues mentioned: 10 hours • 0 hour • 14h • 36h.
- • Source: PubMed PMID 35980956 (2022) — PloS one.
Results excerpt
What the abstract reports
“Sleep extension resulted in greater total sleep time (effect size [90% confidence interval]: 5.35 [4.56 to 6.14]) but greater sleep fragmentation than CON (2.85 [2.00 to 3.70]).”
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.
