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: systematic review / meta-analysis.
- • Population relevance: athlete/trained context.
- • Consistency: synthesis evidence present.
- • Practical recommendation depends on tolerance, context, and whether it protects training consistency.
ELI5
In plain language
To identify optimal CWI protocols in resistance training, endurance exercise, and team sport modalities and measure modality-specific effects on performance and physiological recovery indicators. (systematic review / meta-analysis; n=313 athletes).
In this systematic review / meta-analysis, the abstract is mixed or unclear for 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: To identify optimal CWI protocols in resistance training, endurance exercise, and team sport modalities and measure modality-specific effects on performance and physiological recovery indicators.
- • In this systematic review / meta-analysis, the abstract is mixed or unclear for Recovery speed.
- • Population: n=313 athletes.
- • Protocol cues (title/abstract): 10 min • 15 min.
Protocol
Protocol (as reported)
- • Intervention/exposure: cold water immersion, recovery.
- • Dose/time/duration cues in abstract/title: 10 min • 15 min.
- • Outcomes: 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 (n=313 athletes) working on recovery.
- • Athletes who can measure 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: systematic review / meta-analysis.
- • Population: n=313 athletes.
- • Outcomes measured: Recovery speed.
- • Protocol cues mentioned: 10 min • 15 min.

Results excerpt
What the abstract reports
“Passive recovery was highest in resistance training strength (24 studies, 598 participants, moderate certainty) with worse results in CWI protocols of medium duration and moderate temperature (Hedges' g = 0.00, 95% CrI: -0.38 to 0.38 vs.”

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.
