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.

In plain language
Sekiguchi, Y, Jiwan, NC, Appell, CR, Moya, RM, Ky, AT, Keefe, MS, Dunn, RA, and Luk, H-Y. (controlled study; trained participants).
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: Sekiguchi, Y, Jiwan, NC, Appell, CR, Moya, RM, Ky, AT, Keefe, MS, Dunn, RA, and Luk, H-Y.
- • The abstract doesn’t indicate a clear change in Sleep quality, Recovery speed under the tested conditions.
- • Population: trained participants.
- • Protocol cues (title/abstract): 2 weeks • 2 minutes • 24 hours.
Protocol
Protocol (as reported)
- • Intervention/exposure: impact, hydration.
- • Dose/time/duration cues in abstract/title: 2 weeks • 2 minutes • 24 hours.
- • 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 (trained participants) 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: trained participants.
- • Outcomes measured: Sleep quality, Recovery speed.
- • Protocol cues mentioned: 2 weeks • 2 minutes • 24 hours.
- • Source: PubMed PMID 40845258 (2025) — Journal of strength and conditioning research.
Results excerpt
What the abstract reports
“Impact of hydration status on sleep and recovery after heavy resistance exercise.”
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.
