    Meta-analysis of 17 small RCTs (366 participants) testing cold water immersion vs rest for post-exercise soreness. CWI reduced soreness by ~1 point on a 10-point scale. Classified Inconclusive: no p-value correction for multiple comparisons, low-quality source studies, and soreness alone doesn't fully capture muscle recovery.

    Small RCT (n=21 men) found cold water immersion (10 min, 10°C) after resistance training reduced strength and muscle mass gains vs. active recovery over 12 weeks. Molecular growth markers were also suppressed. However, no passive rest control group exists, so CWI vs. doing nothing remains unknown. Results apply only to young men using this specific protocol.
