The effect of 6 weeks of aerobic, resistance and combination training on serum leptin levels and cardiovascular risk factors in inactive obese girls

The aim of this study was to evaluate the effect of 6 weeks of aerobic, resistance, combination (aerobic + resistance) training on serum leptin levels and cardiovascular risk factors in inactive obese girls.

This research was a quasi-experimental study with a pretest-posttest design with a control group. The statistical sample of this study included 28 inactive obese girls who did not participate in any specific exercise program and were voluntarily selected and randomly divided into 4 groups (control, aerobic, resistance). , Combined) were divided into 7 people. Subjects in the aerobic exercise group (3 sessions per week, 40-60 minutes, 60% -70% of maximum heart rate), resistance training and the combined training group (resistance + Aerobic) practiced three sessions a week. Blood samples were collected one day before and 24 hours after the last training session.

The results of this study showed that the mean difference in the amount of leptin in the experimental group compared to the control group showed a significant decrease (P = 0.001). Also, 6 weeks of aerobic, resistance and combined training (resistance + aerobic) caused a significant reduction in fat mass (P = 0.001), body mass (P = 0.002), cholesterol (P = 0.001) and triglyceride (001). / 0 = P). The results of the variables show a significant increase in the level of high-density lipoprotein (HDL) (P = 0.002).

Combined exercise (resistance + aerobics) seems to be more effective in reducing serum leptin and cardiovascular risk factors in obese people.
