The purpose of this study was to after induced delayed onset muscle soreness, the purpose of this study is to present the effective way on skin temperature changes and cold pain for 14 subjects during to applied with only Cold-jet stream and Cold-jet stream with infra red. 14 healthy men and women who delayed onset muscle soreness eccentric contractions induced by exercise and then the biceps alone was applied to the Cold-jet stream. We measured the time that skin temperature fall from room temperature to 10℃(first period), the time rewarmed from 10℃ to 20℃(second period), the time fall again to 10℃(third period) and the time rewarmed again to 20℃(fourth period). Cold-jet stream with infrared combination therapy was performed with the same method. Results of this study were 1st and 2nd experimental cooling experiments in the to fall to 10℃ Cold-jet stream with infrared combination therapy than in the Cold-jet stream was longer(p<.05). At second period, It took longer in Cold-jet stream with infrared rewarmed than Cold-jet stream to rewarm skin(p<.05). Cold-jet stream with infrared combination therapy than Cold-jet stream had less incidence of cold pain(p<.05). Thickness of biceps brachii were found significant difference related measurment each group was consistent In this study, Cold-jet stream with infrared combination therapy more effective than Cold-jet stream in reduced cold pain and lowering skin temperature. This work was supported by education capacity building project fund of Taegu Science University, 2012.
