The purpose of this study was to investigate effects of walking-physical activity program participation frequency on body composition and fitness level in female middle school students. 41 female students participated during 12 weeks and they are divided into three different physical activity frequency groups in this study. The following items were measured before and after the program : body composition, fitness level. The measured data were analyzed by two-way ANOVA in SPSS(ver 18.0). Results as follow : First, body composition were not significantly different among the groups except waist measurements. Second, fitness levels were significantly different among trunk flexion forward, sit-up and PEI. The group with physical activity 5 times per week had an effect on health promotion. But body compositions were not significantly different among the groups except waist measurements. From these results, we could know that walking-physical activity at least 5 times per week could improve cardiovascular function, flexibility and muscular endurance in female middle school students.
