초록

This study set out to longitudinally compare and analyze connections among physical fitness, body composition and academic performance of a group of students for three years and to emphasize the importance of physical fitness. 333 girls were cluster sampled in middle school, and their data were gathered in physical fitness, body composition, and academic performance for three years(2006, 2007, and 2008). In Middle School Girls there were significant changes(p<.05) to the subjects' physical fitness among the years and there were significant changes(p<.05) to the subjects' body composition among the years. Also there were partial(2006 and 2008) causal relations(p<.05) between physical fitness and academic performance and there were partial(2006) causal relations(p<.05) between BMI and academic performance. The study presents the results of a longitudinal study based on the data of the same group of students for three years(2006∼2008) and a meaningful conclusion that the girls with strong physical fitness(muscle strength and endurance, power, cardio-respiratory endurance, and flexibility) and low BMI perform better academically than the girls with no such conditions.
