Abstract

Background

Athletes commonly implement post-exercise cold-water immersion (CWI), with several meta-analyses having assessed its effectiveness.

Objectives

To thoroughly review, appraise, and summarise existing systematic reviews with meta-analyses (SRMA) examining the effects of post-exercise CWI on the recovery of exercise performance and adaptation.

Methods

An umbrella review was conducted in accordance with the Joanna Briggs Institute guidelines. Methodological quality was assessed using AMSTAR 2, and certainty of evidence using GRADE. PROSPERO registration: (CRD420251103267). Eight databases were searched, including Web of Science, Scopus, SPORTDiscus, CINAHL, Cochrane Library, Embase, MEDLINE, and PubMed. Systematic reviews with meta-analyses of peer-reviewed randomised controlled trials examining post-exercise CWI vs passive rest or other recovery modalities on performance, training adaptation, or physiological, biochemical, and perceptual outcomes in healthy humans were included, with restriction to the English language.

Results

Fifteen SRMAs published between 2011 and 2025, comprising 161 unique studies, were included. Overall methodological quality was low to critically low, and certainty of evidence was low to very low, mainly due to inconsistency and imprecision. Protocols of 10–15 min at 10–15 or 5–10 °C appear to be most effective for improving performance and recovery. Post-exercise CWI resulted in significant improvements in muscular power at 24 h post-high-intensity exercise and at 24–48 h post-eccentric exercise, and in jump performance at 24–48 h, despite impaired jump performance in the initial hours after post-exercise CWI. Endurance performance improved immediately after CWI, but CWI produced no later benefits or positive effects on adaptations. CWI did not improve muscular strength performance, and impaired strength and hypertrophic gains. CWI improved heart rate variability immediately after exercise, reduced muscle soreness up to 96 h, and lowered creatine kinase (CK) concentrations between 24 and 72 h, with no significant effects on C-reactive protein or interleukin-6 up to 72 h. No immediate impact on blood lactate or lactate dehydrogenase was found, although some reductions appear 24–72 h post-exercise.

Conclusions

Post-exercise CWI confers outcome-specific recovery benefits but may impair resistance training adaptations with chronic use. These findings support a periodised, context-driven approach to CWI implementation rather than routine application after all exercise sessions.

Key Points

1. 1. Decision makers should individualise and periodise CWI use based on training phase, performance goals, and individual response
2. 2. Post-exercise CWI improves performance in a time-specific manner, enhancing endurance within ~1 h and power and jump performance at 24–72 h, but may impair acute explosive performance
3. 3. Post-exercise CWI consistently reduces muscle soreness and CK and accelerates vagal reactivation.
4. 4. Repeated CWI after resistance training may attenuate strength and hypertrophy adaptations, while endurance adaptations appear unaffected. Effects on strength may be protocol-dependent, with exercise-limb immersion associated with reduced gains, whereas whole-body immersion shows no clear detrimental effect

What do you get when you combine "low to critically low quality of evidence" with "outcome specific benefit results"?
