The Bruce treadmill protocol is suitable for children 4 years of age and older. Dutch reference values were established in 1987. We considered that children's exercise capacity has deteriorated due to changes in physical activity patterns and eating habits. We determined new reference values and evaluated determinants of exercise capacity. Healthy Dutch children (n=267) aged 6-13 years participated in this cross-sectional observational study. The maximal endurance time on the treadmill was the criterion of exercise capacity. Furthermore, we obtained data on anthropometry, smoking habits, socioeconomic status, ethnicity, sports participation, and school transport habits. The maximal endurance time for children aged up till 10 was lower (up to 1.6 and 1.4 min in girls and boys, respectively) than previously published. Body mass index was negatively, and intense sports participation was positively associated with endurance time (beta=-0.412 and 0.789, respectively; P<0.001). In conclusion, exercise capacity seems to have deteriorated in Dutch children aged up till 10 years whereas the values from the older children are remarkably similar to those from the previous study.
Bruce 跑步机方案适用于 4 岁及以上的儿童。1987 年制定了荷兰参考值。我们认为，由于体育活动模式和饮食习惯的改变，儿童的运动能力已经下降。我们确定了新的参考值，并评估了运动能力的决定因素。健康的荷兰儿童（n=267）年龄在 6-13 岁之间，参加了这项横断面观察研究。跑步机上的最大耐力时间是运动能力的标准。此外，我们还获得了关于人体测量学、吸烟习惯、社会经济地位、种族、体育参与和学校交通习惯的数据。直到 10 岁的儿童的最大耐力时间（女孩和男孩分别低至 1.6 和 1.4 分钟）比之前公布的要低。身体质量指数与耐力时间呈负相关（β=-0.412 和 0.789，分别；P<0.001），而剧烈的体育参与与耐力时间呈正相关。总之，荷兰直到 10 岁的儿童的运动能力似乎有所下降，而较大儿童的值与之前的研究非常相似。
