The purpose of this study was to examine the effect of an 8-week selective aerobic exercise on
cardio-vascular risk factors and anti-risk factors in children with aged between 10 -11 years old.
The subjects were 30 non-athlete students whom were chosen randomly from volunteers. We
divided subjects to two groups, each 15 subject, of experimental group and control group. The
experimental group exercised for a period of 8 weeks with three sessions of exercise of 1 hour with
the 60-70 percent of HRmax and each group was controlled nutritionally 3 days before blood
sampling. The sampling was carried out 24 hours before and after each exercise period for both
groups to examine some blood factors and body such as HDL-c, LDL-c, VLDL-c, TG, TC, apo-A,
apo-B, LBM, BMI, weight and height. Data were analyzed by using the descriptive statistics and
independent-sample t-test. Results showed that following 8 weeks aerobic exercise no any
significant effect was found on the concentrations of HDL-c, VLDL-c, TC/HDL-c and TC in
experimental group, but the differences in the concentrations of TG, LDL-c, apo-A, apo-B, LDLc/
HDL-c and apo-A/B were significant. Finally, according to findings, this type of aerobic exercise
decreases some of the risk factors of cardio-vascular diseases and increases the anti risk factors. So,
it seems that this type of exercises is useful for having healthy body.
