| Abstract |
The purpose of this study was to evaluation the effects of 16 weeks treadmill exercise program participation on endothelial function and plasma ferritin levels in adolescent smokers. Thirty-three adolescent smokers were randomly assigned to control groups(CG, N=17), treadmill exercise groups(EG, N=16). treadmill exercise was performed 4 times a week at the intensity of 50-80% HHR(1-4 weeks; 50% HRR, 5-8 weeks; 60% HRR, 9-12 weeks; 70% HRR and 13-16 weeks; 80% HRR). Endothelial Function, as defined by flow-mediated Vasodilation (FMD) of the brachial artery, and serum corboxyhemoglobin (COHb) were determined at pre exercise and at post exercise. The data from this study were analyzed using repeated measures two-way ANOVA. The following conclusions were obtained by comparing and analyzing the measurement value pre and post of 16 weeks exercise. In the changes of FMD, blood ferritin and COHb levels the exercise group was significantly improved more than control group and pre exercise data(p<.05). In conclusion, regularly aerobic exercise was effective in increasing endothelial function and reducing blood ferritin levels with COHb levels in adolescent smokers. |
