This study was aimed to determine the effects of cryotherapy on creatine kinase(CK) activity and blood testosterone 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 dynamoneter, 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. The measurements of CK activityand blood testosterone were conducted at resting before muscle fatigue, immediately, 30min, 2hours, 4hours, and 6hours after concentric exercise.
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:
1. There was no significant between controlled and cold water immersion condition for creatine kinase activity(p>.05), but creatine kinase activity of within groups was significant for measurement time-courses(p<.05). It was significant between groups fir creatine kinase activity of within groups for recovery period. It seems that cold water immersion were decreased in high speed at LDH level, because of reduced metabolism ratio of muscle and increased blood flow of periphery. The cryotherapy result in a reduction of creatine kinase efflux. The result indicate that variation of creatine kinase activity might be associated with the continued recovery time after application of cryotherapy.
2. There was no significant between controlled and water immersion condition for blood testosterone, It was significant between groups fir blood testostreone of within groups for recovery period. Also blood testosterone of within groups was significant for measurement time-course(p<.05).
It seems to be appeared that the cold water immersion has positive effect to recovery of muscle fatigue after strenuous concentric contraction of leg. In conclusion, it appears that the cryotherapy might be a helper of the recovery of fatigue after strenuous exercise than non-treatment.
