The Effect of Active Recovery Time on Creatine kinase, Lactate dehydrogenase Changes in Response to One Session High Intensity Intermittent Exercise in Female Swimmers
The aim of this study is effect of active recovery time on creatine kinase and lactate dehydrogenase changes in response to one session high intensity intermittent exercise in female swimmers.
In this quasi-experimental study, 10 female swimmers with an age range of 20 to 26 years were placed in two experimental groups 1 (10 people) and experimental 2 (10 people) with a crossover design. Subjects swam 25 meters at maximum speed, the active recovery period in experimental group 1 was three times the duration of swimming and in experimental group 2, it was four times the duration of swimming. The intensity of activity during active recovery is considered to be 50-60% of the heart rate of the subjects, the subjects swam 25 meters until they stopped. Blood samples were collected before the start of the training session and after the recovery phase. ANOVA test with repeated measurements was used to analyze the data at a significance level of P<0.05.
The results showed that there is no significant difference between the two recovery modes (1 to 3 and 1 to 4) in terms of effects on creatine kinase (P≥0.05) and lactate dehydrogenase (p≥0.05).
No difference was observed between triple and quadruple recovery after a bout of intense intermittent swimming activity on the decreasing changes of muscle damage indicators (creatine kinase and lactate dehydrogenase); therefore, it seems that athletes in this field can benefit from both types of recovery according to the conditions of the competition.
