B · Reasonable confidenceCold-water bath or simple rest after one hard training session
Subject: Impact of Cold-Water Immersion Compared with Passive Recovery Following a Single Bout of Strenuous Exercise on Athletic Performance in Physically Active Participants: A Systematic Review with Meta-analysis and Meta-regression
What this means
After strenuous exercise, explosive power had recovered slightly better 24 hours later with a cold-water bath than with passive rest. After high-intensity exercise there was also less soreness. Maximal strength was unaffected.

What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
Cold-water immersion improved perceived recovery and reduced creatine kinase compared to passive recovery, but performance-recovery benefits were small and inconsistent. Temperature and duration matter (11-15°C for 10-15 min commonly studied) — CWI is a useful recovery tool but not a performance enhancer per se.
Who this applies to
Athletes and physically active people, after a single strenuous exercise session.
Size of the research
Fifty-two studies; the total number of participants is not given in the abstract.
What to keep in mind
Measured up to 24 hours after one hard session. After eccentric exercise (muscles braking, as in downhill running), only explosive power improved.
Practical conclusion for REZA
A nuance for cold-water immersion advice: it improves how clients feel and lowers muscle-damage markers, but the effect on actual performance recovery stays small — it's not a miracle fix.
