The Claim
Partial cold-water immersion likely causes a large, immediate inhibition of countermovement jump performance (Hedges' g = –0.94) at 0 hours post-exercise in healthy individuals, indicating significant short-term impairment of explosive power, whereas whole-body immersion results in a smaller, non-significant effect.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a cold-water plunge after exercise might make your jumping power worse right afterward, especially if only part of your body is in the water — but soaking your whole body doesn’t seem to have much of an effect.
See the scientific wording
Partial cold-water immersion likely causes a large, immediate inhibition of countermovement jump (CMJ) performance (Hedges' g = –0.94) at 0 hours post-exercise in healthy individuals, indicating a significant short-term impairment of explosive power, while whole-body immersion shows a smaller, non-significant effect.
What the research says
1 studyThe study found that dunking part of the body in cold water right after exercise significantly reduces jumping power right away, which matches the claim. Whole-body immersion didn’t show a clear difference, but the main finding supports the claim.
