Physical inactivity and obesity have important implications for health. Achieve 60 minutes per day of moderate physical activity (MPA) or vigorous is a recommendation of the World Health Organization (WHO) for children aged between 5 and 17 years. The school environment can be a generator of physical activity (PA) since early childhood education. The purpose of this study is to analyse the minutes of PA and its intensity in schoolchildren of 5 years during recess and to what extent its favours is reaching the recommendations of daily PA promoted by WHO. By monitoring 18 children for 8 days using the Garmin Vivofit Jr. wristband, were obtained the minutes of MPA and the number of steps (NS), disaggregated by time. The daily average of MPA was 87 ± 16 minutes and 9100 ± 1807 NS. During recess, schoolchildren reached an average of 16 ± 4 minutes and 1666 ± 370 NS. Statistically significant differences were found, both in minutes of MPA and in NS in favour of children (p < .001) and 50% more in days without rain compared with rainy days (p < .001). There were no significant differences in MPA (p = .20) or NS (p = .16) depending on the semester of birth. In the recess in the infantile age it reached approximately 25% of the MPA recommended by the WHO.

儿童教育课余时间的体育活动：使用 Garmin Vivofit Jr 腕带进行的试点研究

缺乏身体活动和肥胖对健康有重要影响。世界卫生组织 (WHO) 建议 5 至 17 岁的儿童每天进行 60 分钟的中等强度运动 (MPA) 或剧烈运动。从幼儿教育开始，学校环境就可以成为身体活动 (PA) 的源头。本研究的目的是分析 5 岁学童在课间休息的时间和强度，以及它在多大程度上有利于达到 WHO 提倡的每日 PA 的建议。通过使用 Garmin Vivofit Jr. 腕带监测 18 名儿童 8 天，获得 MPA 分钟数和步数 (NS)，按时间分类。MPA 的日平均值为 87 ± 16 分钟和 9100 ± 1807 NS。休息期间，学童平均达到 16 ± 4 分钟和 1666 ± 370 NS。发现统计上的显着差异，无论是 MPA 分钟数还是 NS 分钟数有利于儿童 (p < .001)，并且与下雨天相比，无雨天数多出 50% (p < .001)。根据出生学期的不同，MPA (p = .20) 或 NS (p = .16) 没有显着差异。在婴儿期的休会期，它达到了世界卫生组织推荐的 MPA 的大约 25%。
