Study note • PMID 23246445
Effect of post-exercise hydrotherapy water temperature on subsequent exhaustive running performance in normothermic conditions.
Low risk + high feasibility for most athletes.
ELI5
In plain language
Despite the widespread use of cold water immersion (CWI) in normothermic conditions, little data is available on its effect on subsequent endurance performance. (randomized trial; trained participants).
The abstract doesn’t indicate a clear change in 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: Despite the widespread use of cold water immersion (CWI) in normothermic conditions, little data is available on its effect on subsequent endurance performance.
- • The abstract doesn’t indicate a clear change in Recovery speed under the tested conditions.
- • Population: trained participants.
- • Protocol cues (title/abstract): 15min.
Protocol
Protocol (as reported)
- • Intervention/exposure: cold water immersion, recovery (vs comparison group).
- • Dose/time/duration cues in abstract/title: 15min.
- • Outcomes: Recovery speed.
- • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.
Fit
Who it helps, and who should skip it
Who it helps
- • Athletes similar to the study population (trained participants) working on recovery.
- • Athletes who can measure Recovery speed with a repeatable workout or time-trial effort.
Who should skip
- • 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: trained participants.
- • Comparator: comparison group.
- • Outcomes measured: Recovery speed.
- • Protocol cues mentioned: 15min.
- • Source: PubMed PMID 23246445 (2013) — Journal of science and medicine in sport.
Results excerpt
What the abstract reports
“Qualitative analyses showed a 95% and 89% likely beneficial effect of CWI-8 and CWI-15 during Ex2 compared with CON, respectively.”

Limits
Limitations & 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.
