effect of 8 weeks of high intensity interval training on plasma levels of adiponectin and leptin in overweight nurses

background: high intensity interval training (hiit) is a novel training method which has received most attention in recent years. the aim of this study was to examine the effect of 8 weeks of high intensity interval training (hiit) on plasma levels of adiponectin and leptin in overweight nurses. m aterials and methods: 27 nurses (mean age 25.81±60 years, height 158.01±67 cm and weight 69.41±25 kg) were voluntarily selected and randomly assigned to three groups (each group 9 subjects): 1. hiit (type 1) including 8 seconds of sprint running and 12 seconds of active recovery 2. hiit (type 2) including 40-m shuttle run with maximum speed 3. control group. hiit (type 1) was performed for eight weeks, three sessions per week, each session 6-9 min. with more than 90% hrmax. hiit (type 2) was applied for eight weeks, three sessions per week with more than 90% hrmax. the control group did not participate in any training protocol. results : the data were analyzed by the dependent t test and anova. the results showed that the hiit (type 1) and (type 2) had significant effects on plasma leptin decrease and plasma adiponectin concentration increase in nurses. one-way analysis of variance (anova) was used to analyze the intergroup data at p˂0.05. c onclusion: the results showed a significant difference in the variables (leptin and adiponectin) among hiit (type 1), hiit (type 2) and control.
