The Effect of Active Recovery Time on HSP 72 Changes in Response to One Session High Intensity Intermittent Exercise in Female Swimmers

The aim of this study was investigating the effect of active recovery time on HSP 72 changes in response to one session high intensity intermittent exercise in female swimmers.the research method was quasi-experimental. 20 female swimmers (age 20 to 26 years ) were selected as a sample and with crossover design  the two experimental group were determined {group1 (n = 10) and group 2 (n = 10)}. The subjectes swam 25 meters distance with a maximum speed.  in the experimental group 1 the recovery period was three times more than the  swimming duration   and in experimental group 2 the recovery period was four times more than to the  swimming duration. The exercise intensity in active recovery was 50 to 60 percent of maximum heart rate. The subjects swam distances of 25 meters until exhaustion. Before the start of the training session and after the recovery phase, the blood samples were collected. To analyze the data, the ANOVA  test with repeated measures was used. The results showed that there wasn't a significant difference between the two recovery periods effectiveness on HSP 72 (1 to 3 and 1 to 4).so the Swimmers can use both type of recovery periods.
