This study was aimed to determine the effects of cryotherapy on lactate acid accumulation following muscle fatigue-inducing concentric exercise of the knee. Eight healthy mans performed a bout of concentric exercise which is composed of three sets of one-hundred fifty maximal reciprocal contraction at 30° /sec. on isokinetic dynarnoneter, Subjects were immersed their exercised leg in cold water at 10℃ and 15℃ for 30min immediately after concentric exercise and then rested in ambient condition lasting 6hours. Also, subjects were participated in controlled condition which was rested in ambient condition during the same period. Lactate acid was measured at resting before muscle fatigue, immediately, 3min, 5min, 10min, 20min 30min, 2hours, 4hours and 6hours after concentric exercising.
The data of measurement was analyzed by using SPSS-PC Windows program. To analyze the difference among three conditions used General Repeated Measure ANOVA.
Based on the findings of the study, the following conclusion has been derived:
There was significant between controlled and cold water immersion condition and time of measurement for lactate acid concentration(p<.05). However, there was no significant between 10℃ and 15℃ cold water immersion condition for lactate acid concentration. Exercise-induced lactate acid of muscle tissue diffuses into blood flow which increase to exercise muscle. Therefore there is a positive effect for rapid recovery of lactate acid because the decreased logic body temperature by cold water immersion result in enhanced blood flow and reduced metabolism ratio
It seems to be appeared that the cold water immersion has positive effect to recovery of muscle fatigue after strenuous concentric contraction of leg. Although the statistical significant from this study exists in the concentration of lactate acid, the results also show that other variables of fatigue have been reduced after application of cryotherapy.
In conclusion, it appears that the cryotherapy might be a helper of the recovery of fatigue after strenuous exercise than non-treatment.
