An ice bath after a hard session feels like treatment, which is a good reason to be suspicious of it. A review pooled dozens of trials against plain rest and kept , maximal strength, soreness and how recovered people felt as four separate questions. Which of them moves?
Across 52 studies, cold water left a small gain in explosive power, less soreness, and a better sense of having recovered a day later. Maximal strength came back no faster than it did with rest. After work the benefit narrowed to explosive power alone.
An ice bath after training looks like a reset button. The useful question is not whether it works, but which specific thing it is supposed to be working on.
A meta-analysis of 52 studies compared against passive rest after hard training. It kept three kinds of outcome apart on purpose: what the body could do, what the athlete felt, and a blood marker of muscle damage.
After intense work there was a small gain in explosive power, less soreness, and a better sense of recovery at 24 hours. For the return of maximal strength there was nothing that stood apart from rest.
That separation is the whole finding. Cold moves one measure and not another. A better feeling can also come from numbed nerve endings rather than a repaired muscle, which is why stayed two separate columns. After eccentric training the benefit narrowed further, to explosive power alone. Water temperature, immersion time, training type and athlete level all varied across the pooled studies.
wat. Across 52 pooled trials, an ice bath eased soreness and nudged explosive power a day later, and did nothing measurable for maximal strength.

Cold can move some parts of recovery without being the reset button the ritual implies.
How do we know?
A systematic review and meta-analysis pooled 52 studies and tracked performance, perceived recovery and a blood marker of muscle damage separately.
What is still unknown
Water temperature, time in the bath, the kind of training and the fitness of the people tested all varied between studies, so the average describes a family of protocols rather than one.
