This study aimed to compare physical activity patterns according to the type of physical education by sex and body mass index categories among Korean adolescents. We analyzed physical activity using an accelerator in a physical education class among Korean middle school students (1305 boys and 1328 girls). An independent -test and regression analysis were conducted to compare differences between the obesity groups by sex. As game play time increased, light activity increased in boys in the normal group. Among the girls, sedentary time decreased in the normal, at-risk for obesity, and obese groups. Moderate activity increased in the underweight, normal, at-risk for obesity, and obese groups. Vigorous activity increased in the normal group. As free activity time increased, sedentary time also increased in the normal, at-risk for obesity, and obese groups. Vigorous activity decreased in the normal group. Among the girls, sedentary time increased in the underweight group. Light activity decreased in the underweight and normal groups. A strategy to increase physical activity during physical education class is to increase game play time for girls and decrease free activity time for boys.
本研究旨在比较不同性别的韩国青少年根据体育课类型和身体质量指数类别进行的体育活动模式。我们使用加速度计分析了韩国中学生体育课中的体育活动（男生 1305 人，女生 1328 人）。对肥胖组进行了独立样本检验和回归分析，以比较不同性别之间的差异。随着游戏时间的增加，正常组的男生轻度活动增加。在女生中，正常、超重和肥胖组的久坐时间减少。在消瘦、正常、超重和肥胖组中，中度活动增加。正常组的剧烈活动增加。随着自由活动时间的增加，正常、超重和肥胖组的久坐时间也增加。正常组的剧烈活动减少。在女生中，消瘦组的久坐时间增加。消瘦和正常组的轻度活动减少。在体育课上增加体育活动的策略是增加女生的游戏时间，减少男生的自由活动时间。
