Recently, icing for emergency treatment of injuries or restoration of tiredness is very popular in the sports fields. The method of icing according to time and circumstances and there is no definition based on scientific demonstration. This study investigated that icing shortly after cycling affected vastus lateral muscle, which is agonist of cycling, by skin temperature and hemodynamics with NIRS (Near-Infrared Spectroscopy). First we examined effects of icing during rest. Then we examined that the effects of icing or not shortly after cycling. The results were as follows; 1) Veins of the skin surface and skeletal muscle were constricted and hemodynamics was changed by icing at rest. 2) Although veins of the skin surface were constricted. in regard to those of the skeletal muscle, some were constricted and others were not. The subjects whose skeletal muscle were not constricted have the ability to expand greatly after exercising than those of them were constricted. The limitation of this study was that NIRS can't measure the region under the icing spot. To compare the individual NIRS data in more detail, it is necessary to measure with another way like the arterial occlusion to normalize muscle oxygenation levels.
