Purpose The purpose of this study is to find out the difference in cardiorespiratory endurance, flexibility, and muscular strength and muscular endurance according to the opening of the playground, gymnasium, and auditorium in the 5th and 6th grades of elementary school. Methods This study was based on statistical data provided by the EDSS provided by KERIS. The data on cardiopulmonary endurance, flexibility, and muscle strength and muscular endurance of 413 female students and 413 male students were analyzed for 400 5th graders and 420 6th graders nationwide. Result There were statistically significant differences in cardiopulmonary endurance, flexibility, and muscular endurance among female students in terms of physical factors according to whether or not the playground was opened(ρ<0.05), and there were significant differences in cardiopulmonary endurance, muscular strength, and muscular endurance among male students in female students, cardiopulmonary endurance according to gym opening was higher than unopened, so there was a statistically significant difference(ρ<0.05). In addition, in male students, there was a statistically significant difference in the strength and endurance according to the gym opening because the gym opening was higher than the gym open(ρ <0.05). However, there was no statistically significant difference in cardiopulmonary endurance, flexibility, and muscular endurance according to the opening of the auditorium in female students. In addition, there was a statistically significant difference in cardiorespiratory endurance according to the opening of the auditorium in male students, as the opening of the gymnasium was higher than that of the open auditorium(ρ<0.05). Conclusion The conclusion of this study is that the opening of school facilities in sports fields, gym, and auditorium has a positive effect on the improvement of cardiorespiratory endurance, flexibility, and muscular and muscular endurance of elementary school students.
