The Effect of ۸ Weeks of HIIT on Inflammatory Factors in Overweight Adolescent Boys [In Persian]

چکیده مقاله

Abstract

Obesity is one of the most important public health challenges of the present century, which increases the plasma levels of inflammatory cytokines and decreases anti-inflammatory and anti-atherogenic agents. High intensity interval training may be able to stop or reverse these destructive effects. Therefore, the aim of this study was to investigate the effect of 8 weeks of interval training on inflammatory factors in overweight adolescent boys. In a quasi-experimental research project, from overweight adolescent boys (13-18 years old, mean height 154.33 cm, mean body mass index 27.05 kg/m²), 30 subjects were voluntarily assigned to 3 groups (10 subjects each group): short-term interval training (nine 30-second bouts, 100 to 110% of maximum speed with 150 seconds of rest), long-term (four 150-second bouts, 90 to 95% of maximum speed with 240 seconds of rest) and control. 48 hours before the beginning and the end of the training protocol, weight, height, body mass index and fat percentage were measured by a body composition apparatus and blood samples were collected to determine the interleukin-6, interleukin-10 and C-reactive protein indices. The results showed that 8 weeks of high intensity interval training increased interleukin-10 and decreased C-reactive protein. But it had no significant effect on interleukin-6. It was also found that there were no differences between short-term and long-term HIIT in influencing the desired indicators. Based on these findings, it can be said that overweight or obese adolescents may be able to use HIIT to boost their anti-inflammatory system by increasing interleukin-6 and decreasing C-reactive protein. But more studies are needed to determine the effect of this training on interleukin-6.
