In recent times, something that has become standard practice in Sports/GAA clubs throughout the country is the use of a ‘wheelie-bin’ or similar vessels filled with water and ice for post-training treatment. When asked the question of why this practice is carried out, there are few who can answer correctly by explaining the effects of physically dipping your body into the iced water. The general instruction to the player is to jump in and submerge themselves in the near freezing water for as long as possible then get out and take a warm shower. From my experience, there’s certainly an argument to be made that the sole rationale behind the induction of make-shift cryotherapy treatment units ie. wheelie-bins in sports clubs seems to be that because others are doing it, well, so should we
I personally find this practice subjective for a number of reasons. Firstly, if a person gets injured, the R.I.C.E. principle applies. Taking the I. as a connotation for ice in the treatment, is to extract the heat out of the injury site. The interface in which the ice extracts and the concentration of heat is at its optimum where the ice burn occurs. In order to prevent this, a barrier or medium is applied such as a damp towel etc to avoid the burn.
This begs the questions of how you might prevent ice burn when you immerse yourself in iced water? What acts as the barrier to prevent the burn? The required effect of the process is to gain a vasoconstriction.
In cryotherapy treatment of a foot injury, the temperature is tested to the patient’s threshold. The foot is immersed in cold water to effect a vasoconstriction. It is then immersed in hot water to effect vasodilation. In the absence of hot water, the shower is used in the ‘Wheelie-Bin’ treatment. Does it have the same effect as the immersion of hot water? Not necessarily.
In 2010 an interesting article on the subject was published in the Irish Independent. Professor Donnelly et al U.L. carried out tests over a three year period on cryotherapy ultimately finding that there was no proven benefit in reducing muscle soreness through the use of Ad-hoc ice baths. However, the definitive conclusion is the risk of Bronchospasm and ice burn. It also begs the question to be asked is medical clearance required prior to engaging in this practice?
