The trend in pediatric sport organizations is to regroup activities into tournaments. Sports-related injuries in children are a public concern.
To evaluate the association between sport injuries and consolidation of physical activity in children.
A case-crossover study.
The emergency department of a tertiary care hospital for approximately 1 year in 2006.
Eligible participants had to be between 8 to 16 years of age, presenting to the emergency department for an acute injury that occurred during a timed organized sport event.
A standardized questionnaire was used to evaluate the number of hours of organized physical activity, which was defined as a supervised exercise leading to competitions. The number of hours of activity was compared between case periods (48 hours and 7 days) and control periods of same length.
An injury was defined as any acute problem with organic tissue that occurred during a sport.
On average, participants performed 136 minutes of organized sport activity in the 48 hours preceding the injury for a mean difference of 8 +/- 18 min. They also performed 356 minutes of organized sports in the 7 days prior the injury. This represented an increase of 40 +/- 31 minutes compared to the control periods.
More injuries were observed if the athletes had increased the concentration of activity in the 7 days prior. Although small, this difference reflected a minor clinical effect. In our study, we failed to disclose an association for the period of 48 hours.
儿科体育组织的趋势是将活动重新组织成锦标赛。儿童与运动相关的损伤是公众关注的问题。
评估儿童运动损伤与体育活动集中化之间的关联。
一项病例交叉研究。
2006年一家三级护理医院的急诊科，为期约一年。
符合条件的参与者年龄必须在8至16岁之间，因在有时间限制的有组织体育赛事中发生的急性损伤而到急诊科就诊。
使用标准化问卷评估有组织体育活动的时长，有组织体育活动被定义为导致比赛的有监督的锻炼。比较病例期（48小时和7天）与相同长度的对照期内的活动时长。
损伤被定义为在运动期间发生的任何有机组织急性问题。
平均而言，参与者在受伤前48小时内进行了136分钟的有组织体育活动，平均差异为8±18分钟。他们在受伤前7天也进行了356分钟的有组织体育活动。与对照期相比，这增加了40±31分钟。
如果运动员在之前7天内增加了活动集中度，则观察到更多损伤。尽管差异较小，但这一差异反映了轻微的临床效应。在我们的研究中，我们未能揭示48小时期间的关联。
