Cold water immersion outperforms whole-body cryotherapy for post-exercise soreness, review finds

A systematic review and meta-analysis pooled data from 13 randomized controlled trials to compare cold water immersion and whole-body body cryotherapy as recovery tools after strenuous exercise. Cold water immersion was associated with greater short-term reductions in delayed-onset muscle soreness, while body cryotherapy showed a marginal and statistically uncertain edge in restoring jump performance.

What the study found

The meta-analysis found that cold water immersion was associated with meaningfully greater relief from delayed-onset muscle soreness compared with body cryotherapy, with the advantage most pronounced in the first 24 hours after exercise. The pooled effect size for soreness reduction was moderate and the confidence interval did not cross zero, lending reasonable statistical credibility to that particular finding.

For jump performance — a proxy for lower-body power recovery — body cryotherapy showed a numerical advantage over cold water immersion, but the authors describe this effect as marginal and note that substantial variability across the included trials makes the result difficult to interpret with confidence. The authors themselves flag heterogeneity as a limiting factor for this outcome.

Both modalities were associated with faster recovery of muscle function and reduced soreness relative to passive recovery conditions, suggesting that active cold-based recovery in general offers benefits to physically active adults. However, the head-to-head comparison is the central contribution here, and the soreness finding is the more robust of the two.

The participant pool spanned ages 20 to 47 years and was drawn from physically active populations, so the findings are most applicable to healthy, recreationally or competitively active adults rather than clinical or sedentary groups.

Limits worth knowing

The combined sample across all 13 trials was only 214 participants, which is modest for a meta-analysis and limits statistical power for subgroup analyses. The included studies varied in exercise protocols, participant fitness levels, and how outcomes were measured, contributing to the heterogeneity the authors acknowledge — particularly for jump performance. The review covered literature through December 2024 but was restricted to specific databases, so some eligible trials may have been missed. Funding sources for the individual trials are not discussed in the abstract, and it is unclear whether any industry relationships existed among the primary study authors. Long-term effects beyond the acute recovery window were not examined.
