To investigate the relations between sedentary behaviors and health-related physical fitness and physical activity in middle school boys and girls.
Students (n = 1515) in grades 6-8 completed the Youth Risk Behavior Survey sedentary behavior questions, the FITNESSGRAM physical fitness items, and FITNESSGRAM physical activity self-report questions.
When students reported ≤ 2 hours per day of sedentary behaviors, their odds of achieving the FITNESSGRAM Healthy Fitness Zone for aerobic capacity, muscular strength and endurance, flexibility, and body composition increased. Similarly, the odds of achieving physical activity guidelines for children increased when students reported ≤ 2 hours per day of sedentary behaviors.
Results illustrate the importance of keeping sedentary behaviors to ≤ 2 hours per day in middle school children, thus increasing the odds that the student will achieve sufficient health-related fitness benefits and be more likely to achieve the national physical activity guidelines.
探讨中学男生和女生久坐行为与健康相关身体素质及身体活动之间的关系。
6至8年级的1515名学生完成了青少年风险行为调查中的久坐行为问题、 FITNESSGRAM身体素质项目以及FITNESSGRAM身体活动自我报告问题。
当学生报告每天久坐行为≤2小时时，他们达到FITNESSGRAM有氧能力、肌肉力量和耐力、柔韧性及身体成分健康体能区的几率增加。同样，当学生报告每天久坐行为≤2小时时，达到儿童身体活动指南的几率也会增加。
结果表明，中学儿童每天将久坐行为控制在≤2小时很重要，这会增加学生获得足够健康相关体能益处的几率，并且更有可能达到国家身体活动指南的要求。
