Forty-eight overweight or obese Iranian children were randomly assigned to exercise with control (n = 16)، self – control(n = 16)، intervention groups and control(n = 16). Two-way mixed ANOVA testswere used to compare any changes between the groups in terms of percentage body fat، physical fitness، and systolic and diastolic blood pressure and other mextabolic syndrome indices. The Measurements were taken before and after a two-month mixed-exercise (aerobic and resistance) was implemented.

There was a significant difference between triglyceride and systolic blood pressure of subjects before and after exercise. There is no significant difference between FBS levels in two exercise groups.
