Abstract：
UNASSIGNED: The World Health Organization (WHO) recommends that children and adolescents incorporate vigorous intensity activities (VIAs) at least three days a week. This recommendation has not been sufficiently studied using objective methods, such as accelerometry. Physical education classes and extracurricular sports activities are optimal opportunities for compliance with this recommendation.
UNASSIGNED: To identify VIAs through bouts of vigorous physical activity (VPA-Bouts) evaluated with accelerometry and, with this, to know the compliance with the recommendation on VIAs.
UNASSIGNED: A cross-sectional study of the habitual physical activity of 353 children (8-9 years old) was carried out using accelerometry and participation in organized extracurricular sports activities was asked through a questionnaire. School days with and without physical education class, weekends, and the average weekly day were identified, as well as school time and out-of-school time. A VPA-Bout was defined as an interval of at least 60 minutes with a proportion of VPA of at least 16.7% in boys and 12.5% in girls (10.0 and 7.5 minutes/hour of VPA, respectively).
UNASSIGNED: The average daily time in organized extracurricular sports activities declared by questionnaire and the average daily duration of the VPA-Bouts evaluated with accelerometers in the extracurricular period was 21.3 (SD 19.8) and 23.9 (SD 31.2) minutes, respectively, in boys, whereas, in girls it was 20.2 (SD 17.4) and 11.0 (SD 16.9) minutes, respectively. In school time including a physical education class, there was a higher proportion of VPA-Bouts than without these classes (with: 28.6%, without: 2.1%, p < 0.001). Children who reported at least three weekly hours of organized extracurricular sports activities accumulated a higher proportion of school afternoons with VPA-Bouts than those with fewer weekly hours of this type of activities (≥3 hours/week: 27.5%, <3 hours/week: 9.3%, p < 0.001). On the weekend, boys who reported at least three weekly hours of organized extracurricular sports activities performed more VPA-Bouts than those participating in less weekly hours, while in girls no significant differences were observed (weekend; boys, ≥3 hours/week: 26.0%, <3 hours/week: 9.0%, p < 0.001; girls: 8.3%, 8.0%, p = 0.917). Compliance with the recommendation to incorporate VIAs at least three days a week was 23.8%. Children who reported at least three weekly hours of extracurricular sports activities achieved higher compliance than those who reported fewer extracurricular activities (≥3 hours/week: 35.1%, <3 hours/week: 12.7%, p < 0.001). Additionally, boys showed higher compliance rates than girls (boys: 32.9%, girls: 15.3%, p < 0.001).
UNASSIGNED: One in every four children met the WHO recommendation to incorporate VIAs at least three days a week, as evaluated by accelerometry. Physical education classes and extracurricular organized sports activities contributed to compliance with this recommendation.

摘要：
■世界卫生组织（WHO）建议儿童和青少年每周至少三天进行高强度活动（VIA）。使用客观方法尚未充分研究此建议，比如加速度计。体育课和课外体育活动是遵守此建议的最佳机会。
■通过用加速度测量法评估的剧烈体力活动（VPA-Bouts）来识别VIA，有了这个,了解对维也纳机构建议的遵守情况。
■使用加速度测量法对353名儿童（8-9岁）的习惯性体育活动进行了横断面研究，并通过问卷询问了参加有组织的课外体育活动的情况。有体育课和没有体育课的学校日子，周末,确定了每周的平均天数，以及上学时间和课外时间。VPA-Bout定义为间隔至少60分钟，男孩的VPA比例至少为16.7％，女孩的VPA比例至少为12.5％（VPA的10.0和7.5分钟/小时，分别)。
■通过问卷调查宣布的有组织的课外体育活动的平均每日时间和课外期间用加速度计评估的VPA-Bouts的平均每日持续时间为21.3（SD19.8）和23.9（SD31.2）分钟，分别,在男孩中，然而,在女孩中，它是20.2（SD17.4）和11.0（SD16.9）分钟，分别。在学校时间包括体育课，VPA-Bouts的比例高于没有这些类的比例(有：28.6%，不包括：2.1%，p<0.001)。报告每周至少有三个小时的有组织的课外体育活动的儿童在VPA-Bouts的学校下午的比例高于每周此类活动时间较少的儿童（≥3小时/周：27.5％，<3小时/周：9.3%，p<0.001)。在周末,报告每周至少有三个小时的有组织的课外体育活动的男孩比每周参加较少的男孩表现出更多的VPA-Bouts，而在女孩中没有观察到显著差异(周末；男孩，≥3小时/周：26.0%，<3小时/周：9.0%，p<0.001；女孩：8.3％，8.0%,p=0.917)。对每周至少三天纳入VIA的建议的遵守率为23.8%。报告每周至少有三个小时的课外体育活动的儿童比报告课外活动较少的儿童的依从性更高（≥3小时/周：35.1％，<3小时/周：12.7%，p<0.001)。此外,男孩的依从率高于女孩(男孩:32.9%，女生:15.3%,p<0.001)。
■每四个儿童中就有一个符合世界卫生组织的建议，即每周至少三天纳入VIA，通过加速度测量法评估。体育课和课外有组织的体育活动有助于遵守此建议。
