When More Recovery Is Not Better
Regular cold-water immersion in hypertrophy-focused resistance training may reduce muscle growth and adaptive signalling, which makes it situational rather than default.
- Pain that is sharp, localized, or persists beyond normal soreness: see a clinician
What the evidence says
The sources are meta-analyses, systematic reviews and one narrative review of cold-water immersion and other recovery methods, for soreness, performance and adaptation. On adaptation: Poręba 2025 (systematic review) reports that regular cold-water immersion in hypertrophy-focused resistance training may reduce muscle growth and type II fibre adaptations, with endurance effects largely neutral, and concludes that responses are context- and individual-dependent; Brankowska 2026 (narrative review) reports that cold-water immersion may interfere with adaptive processes after resistance exercise. On acute recovery: Machado 2015 (meta-analysis) reports cold-water immersion more effective than passive recovery for soreness; Zhu 2026 (meta-analysis) reports lower creatine kinase and soreness without functional recovery, and a transient impairment of explosive power immediately after exercise; Patel 2025 (systematic review) reports consistent reductions in soreness and muscle-damage markers within 24 to 48 hours; Moore 2022 (meta-analysis) reports cold-water immersion often better than other modalities for soreness, with air cryotherapy better for strength and immediate power; Li 2024 (systematic review) reports no recovery strategy with consistent benefits in endurance athletes. None of these sources states the size of an adaptation cost.

Each source below is shown with its study design and a link to the original study, or, where it is not a completed research paper, with what kind of record it is; those are not counted. This is the audit trail.
Why do some records show a record type instead of a study design?
A study design is shown for a completed, peer-reviewed paper. A registered protocol, a preprint, a conference abstract, a referee report or a book chapter has not been through peer review as a finished paper, so it is labelled for what it is, and it is counted in no source count. Where a record could not be confirmed as a completed paper at all, it says so rather than guessing. They all stay in the list, and their DOI still resolves, because the count of what was screened is part of the audit trail.
- Protocol / registration A registered plan for a review or trial, not its results.
- Preprint Posted by its authors before peer review.
- Conference abstract A conference summary rather than a peer-reviewed paper.
- Peer-review report A referee's report on a paper, not the paper itself.
- Guideline / position stand A recommendation derived from evidence, which is a step further from the data than the evidence itself.
- Book chapter A chapter in a scholarly book rather than a journal paper.
- Type not recorded Our record does not say what kind of publication this is, so it is counted in no source count. That is a gap in our data, not a judgement about the research.
“Abstract only” means the review read that paper’s abstract, not its full text; “screened only” means it was included at re-screening and not extracted. Both stay in the trail with their DOI, because how a source was read is part of the audit.
