Recently, there have been diverse types of physical activities supported by government policy in S. Korea. However, these activities may not be effective if they do not reach to moderate to vigorous level. This study designed school physical education system based on SPARK program, which include traditional physical education, sports club based physical activity, after school physical activity, and Saturday physical activity, to evaluate its effectiveness associated with physical fitness and empirical meanings of physical activity. This study employed a mixed method research paradigm for better understanding. Among various mixed method paradigm stances, this study employed "blending strategy" for complementary analysis. First of all, the effectiveness in health condition was evaluated by quantitative data. Specifically, physical fitness and lifestyle were analyzed by Helmas, IPAQ, and Accelerometer respectively. Second, empirical meanings of physical activity were analyzed by both Photovoice and in-depth interview which are qualitative research method. The result of this study first showed that a specially designed school physical activity program based on the SPARK contributed to improve students' physical fitness and lifestyle as well, however, there were important differences between male and female students. Second, physical achievement, alteration of spatiotemporal meaning, and change of societal relationship emerged as important themes. Further, these themes showed that they played an important role to maintain students' motivation in physical activity and consequently physical activity promotion was invigorated in school. Based on these results, we synthesized investment factors and process factors and outcome factors respectively. Finally, we suggested alternative teaching methods and suggestions for following research to overcome gender issues.
