The adolescent period seems to be critical in age-related decline of physical activity. To influence physical activity behavior in children and youth, it is necessary to determine factors affecting physical activity which are related to seasonal, monthly or weekly period. Therefore, the purpose of this study is to collect one year pedometer self-monitoring data to find out the year-round variability of physical activity in high school girls. Nine volunteering girls from a high school participated in this study. Girls were asked to wear pedometer at their waist during each day of one year and record steps per day and daily behavior. We obtained 2118 person-day, each girl recorded 303 days. The days with lowest number of steps were Saturday and Sunday. The highest number of steps was obtained on days with regular physical education lesson – Wednesday. The month with the lowest average number steps/day was February and the average number steps/day was the highest in June. Although this study has several limitations (e.g. low sample size), the variability in year-round physical activity has been found across days and autumn, winter, and spring months. Verf.-Referat
