| ABSTRACT |
|
The purpose of current study was to investigate the correlations of physical activity with cardiorespiratory fitness (CRF), body composition, and cardiovascular risk factors in elementary school girls. A total of 24 girls (11.79±0.78 years) voluntarily participated in the physical activity intervention stuy. Before and after the intervention, all the participants underwent a series of measurements including body composition, obesity indices, CRF, and cardiovascular risk factors. Then each participant was invited to participate in a physical activity intervention targeting at 13,000 steps/day, which was predetermined in our preliminary study, for 12 weeks. All participants worn the Life-corder accelerometer to monitor their daily physical activities including its volume and intensity. Height, weight, body mass index, CRF were increased significantly after the 12-week PA intervention. PA volume was positively related to CRF and systolic blood pressure (SBP). Moderate and high PA intensities were positively relate to height growth. In conclusion, the current findings of the study suggest that substantial amount of physical activity (i.e., accumulated 13,000 steps per day) including regular exercise with moderate or higher intensities would be necessary for the improvements of in CRF, obesity indices, and cardiovascular risk factors as well as height growth. |
