"Ice-water immersion offers no benefit for pain, swelling, isometric strength and function, and in fact may make more athletes sore the next day."
It was unclear why the ice may had this effect, and the researchers said further study was needed.
John Brewer, Director of the Lucozade Sports Science Academy, said he did not find it surprising that there was no difference between the two samples.
"I don't find it hard to believe that the ice doesn't have any long-term benefit, although I would question whether the ice group really did feel more pain after 24 hours than the tepid group. The problem with pain is that it is subjective and very hard to measure," he said.
