An ice bath after training always helps
The evidence
Timing decides the trade: after a race or multi-event day, cold may return you to usable faster; immediately after lifting it blunts anabolic signalling and costs some long-term growth.
The mechanism, in brief
The key variable in cold water immersion is not toughness but timing. After endurance races or multi-event days, cold may help you return to usable status faster; immediately after strength training, it may blunt inflammation and anabolic signaling (anabolic signaling — the chemical signals that build muscle),…
