New research by the Queensland University of Technology published in the Journal of Physiology has concluded that ice baths may not have the post workout benefits that many claim that they have.
The idea behind the ice bath is that the cold water reduces the temperature of the muscles and also reduces blood flow, this is thought to help the repair of muscles that have broken down or possibly been damaged during a workout, yet there is no actual data using humans that back up these claims.
The Queensland trial, however, had 9 active men between the ages of 19-24 do resistance training three times a week after each session they were required to either to spend ten minutes in water measuring 10 degrees or they had to do a warm down on an exercise bike.
The research team then took biopsies from the muscles of the participants two hours after the ice bath or warm down and again 24 hours and 48 hours after. They then examined these muscle samples for changes in the genes and proteins that display signs of inflammation in the muscles.
The comparison of the data between the two recovery groups led the research group to conclude that athletes may be better off with a light warm down instead of the commonly used Ice Bath.
This study also suggests that reducing muscle inflammation after an injury can actually disrupt muscle repair.
Despite indicating that an old fashioned Warm Down may be the better way to help muscles post workout it also does not rule out that there is some benefit from cold water immersion.
The study does give insight into an area where science is constantly changing and evolving it doesn’t take into account the fact that most of the elite athletes that were highlighted in the press articles as being fans of the Ice bath aren’t using them after resistance training as was the case in this study.
Another fault that could be cited against this study is simply their limited number of participants in the trial itself, a conclusive answer cannot be drawn until this study is

He firmly assured us that the most important of all recovery techniques is “Sleep and Nutrition”, as simple as it sounds the basics seem to still be the most important recovery tools of all.
