The Effects of Aerobic Training with Different Intensities on Some Cardiovascular Risk Factors in Young Girls

The aim of the present study was to investigate the effect of two aerobic training programs with different intensities on some cardiovascular risk factors in young girls. For this purpose, 42 girls (mean age 20.59±1.46 years, height 160.29±4.75 cm, weight 59.23±8.82 Kg, BMI 22.08±3.41 kg/m2, %BF 15.42±3.85 and Vo2max 25.34±3.96 ml/kg/min) were voluntarily participated in this study and divided into three groups randomly: aerobic training (intensity 65-75% maximal heart rate), aerobic training (intensity 80-90% maximal heart rate) and control group. Then, two experimental groups performed aerobic training three sessions per week for 8 weeks. One-way ANOVA showed no significant differences among the three groups in total cholesterol, triglyceride, LDL-C, HDL, HDL2, HDL3 and apoA-1 (P>0.05). Moreover, the results indicated that aerobic training with both 65-75% maximal heart rate and 80-90% maximal heart rate significantly increased VO2max in young girls (P<0.05). This study showed that aerobic training with two mentioned intensities had no significant effect on cardiovascular risk factors in healthy young girls, but in it can improve aerobic fitness in these volunteers.
