ABSTRACT
The purpose of this study was to evaluate cardiorespiratory fitness (CRF), activity level, some health-related anthropometric variables, sedentary behaviour and socioeconomic status (SES) of 7-11 year old boys in the city of Ardabil, Iran. Of 21 253 school boys aged 7-11 years, 766 participated in this study using the cluster sampling method. Subjects underwent standard anthropometry. One-mile test was used to evaluate ·VO2max. BMI cut-off points were used to identify weight status. Child’s TV watching and video playing daily time (TVVPT) was taken for sedentary behaviour evaluation. SES and activity level were measured by standard questionnaires. Of all participants, 8.9�0(N=68) of students had CRF lower than normal and 58.6�0(N=449) of them had inadequate physical activity. There was a significant adverse relationship between ·VO2max and body mass index (BMI), waist to height ratio (WHtR), waist circumference (WC), and fat mass (FM) (p
