Recent network meta-analytic work evaluates how CWI dose (time/temp) influences recovery after acute muscle damage. But for resistance training, a meta‑analysis titled “Throwing cold water on muscle growth” suggests post‑exercise CWI may reduce hypertrophy gains (effects may be modest, but direction matters).
Try this: reserve CWI for competition phases or high‑frequency training blocks; avoid immediate post‑lift plunges during hypertrophy blocks.
