Background and Objective: Interleukin-6 is the major cytokine involved in initiating the acute phase response, which triggers the synthesis of certain proteins in the liver, such as C-reactive protein. The aim of this study was to investigate the effect of different periods of active recovery on serum IL-6 and hs-CRP response after one session of intense intermittent activity in female swimmers.Methods: In this quasi-experimental study, 10 female swimmers ranging in age from 20 to 26 years were divided into two experimental groups: group 1 (n = 10) and group 2 (n = 10). The subjects swam the distances of 25 meters with maximum speed, the active recovery time in experimental group 1 was three times the duration of swimming and in experimental group 2 was four times the duration of swimming. The intensity of activity during active recovery was considered to be 50 to 60% of the maximum heart rate of the subjects, the subjects swam distances of 25 meters until exhaustion. Blood samples were collected before the start of the training session and after the recovery phase. ANOVA with repeated measures was used to analyze the data. All statistical operations were performed using SPSS software version 16 and the significance level was considered P <0.05.Result: The results of this study showed that there was no significant difference between female swimmers in the effect of two periods of active recovery 1: 3 and 1: 4 on serum hs-CRP (P=0.17) and IL-6 (P=0.24) response after one session of intense interval swimming to exhaustion.Conclusion: Swimmers can use both 3-fold recovery times and 4-fold recovery times, and these two types of recovery was not significantly different in terms of affecting IL-6 and hs-CRP response.
