Abstract

The purpose of this study was to analyze the effects of recovery types of cold water immersion after a high-intensity intermittent performance on blood fatigue substances in Judo athletes. For this study, 10 Judo athletes conducted aerobic cool-down, continuous cold water immersion, and intermittent cold water immersion after high-intensity interval(HII) performance at weekly intervals. Blood samples were collected from an antecubital vein and fingertip before, immediately, and 15 min after high-intensity interval performance for lactate and ammonia analysis. The results are as follows.BR First, blood lactic acid according to the cold immersion recovery types showed no difference between groups after high-intensity interval exercise. Second, there was a significant difference in blood ammonia according to the cold immersion recovery types after high-intensity interval exercise.BR In conclusion, for judo players, the intermittent cold immersion method after high-intensity interval exercise can be a more efficient means in terms of muscle fatigue recovery.
