effect of the contrast of fat percentage on risk factors cardiovascular diseases in [12-15] year old Jordanian Children

ABSTRACT

This study aimed to identify the effect of the contrast of fat rate on the Cardiovascular Diseases Risk Factors T-C, LDL-C, HDL-C, Tg, T-c/HDL-c Ratio, and blood Pressure and the drop of Cardiorespiratory fitness, and the rates of their occurrence to the Jordanian children in the ages between 12 - 15, and the relation between the variables of the body composition and cardiovascular diseases risk factors for in [12-15] year old Jordanian children. The study sample consisted of [102] children of those who don't practice specialized physical activity and suffer from any manifest diseases. They were chosen randomly and the two homogeneous of the age variables are [13.77 +/- 1.91] y, weight [54.26 +/- 16.25] kg, height [1.59 +/- 13.18] m, BMI [21.01 +/- 4.92] kg/m2, BSA [1.54 +/- 0.26] m2, HRrest [73 +/- 7.35] b/m, Data has been statistically analyzed by using One-way ANOVA followed Scheffe Tests, Pearson Product Moment Correlation Coefficients. The findings indicated statistic variances that show all the variables of blood lipids and cardiorespiratory fitness and to the advantage to children who have low rate of fat in their bodies [>15%]. They also indicated that there is no difference in the variables of SBP and DBP, and there is a rise in the susceptible risk factors cardiovascular diseases for children who have high rate of fat in their bodies [>/= 25%], and they indicated that there are correlations between the variables of body composition and risk factors cardiovascular diseases; especially regarding the rate of fat in the body and BMI. The researcher recommended doing studies in order to identify which of the areas, which store more fat, in children bodies affect the rise of the blood lipids level rate and the relation of that with the indicators of the health-related physical fitness
