Abstract :

this study purpose is to determining the effect of two types high intensity exercise (HIIT) on some Immunological indices in young overweight girls. 24 girls with age 25/75±1/18 y, height: 161/29± 4/23cm, weight 74/51±6/27 kg، fat 30/70± 2/23%, BMI 28/66±1/89 kg/m2 voluntarily participated and randomly divided into three experimental HIIT1 group (n=8), HIIT2 group (n=8) and control group (n=8). Group HIIT1 in each session running four sets 30s with 19 to 20 rate of perceived exertion (RPE) Borg scale and two minutes of rest between sets. HIIT2 group running four sets of 60 s with the same intensity and four minutes rest between sets, training protocol performed three times a week and performed four weeks. 48 hours before and 48 hours after exercise, blood samples were taken. For analyzing data, use Mixed between-within Subjects analysis of variance in level of (P<0.05). mean percent of LYM, NEUT and NEUT levels did not change significantly (P>0.05). The mean of lymphocytes showed significant increase only in Group HIIT2 (P=0.005), difference between groups was not significant (P>0.05). leukocytes in the Both experimental groups was significant increase (P<0.05). The mean of immunoglobulin A in both experimental groups showed a significant increase (p<0.05). In the mean of immunoglobulin G, significant changes were observed only in HIIT1 group (p<0.05). immunoglobulin M did not change significantly in any of the groups (p>0.05). it seems that Short-term HIIT increase leukocyte counts and immunoglobulin A and G to a greater extent than medium-term HIIT.
