-
Cold-water immersion shows mixed effects on post-exercise muscle strength recoveryAcute cold-water immersion may modestly reduce subjective soreness but does not meaningfully improve strength recovery and may temporarily impair explosive power immediately post-exercise—timing and context matter for its practical use.
-
