Emerging evidence has demonstrated the strong link between cardiorespiratory fitness and multiple aspects of health (i.e., physiological, physical, psychosocial, cognitive), independent of physical activity, among school-aged children and youth. Cardiorespiratory fitness is a trait that does not vary substantially from day-to-day, and provides an indication of recent physical activity levels, making it an important possible indicator of population health. Thus, the objective of this dissertation was to investigate the utility of cardiorespiratory fitness, measured using the 20-m shuttle run test, as a broad, holistic health indicator for population health surveillance among children and youth. To achieve this objective we completed 7 manuscripts, all prepared for submission to peer-reviewed, scientific journals: (1) Systematic review of the relationship between 20-m shuttle run performance and health indicators among children and youth. (2) Review of criterion-referenced standards for cardiorespiratory fitness: what percentage of 1 142 026 international children and youth are apparently healthy? (3) Cardiorespiratory fitness is associated with physical literacy in a large sample of Canadian children aged 8 to 12 years. (4) International variability in 20-m shuttle run performance in children and youth: Who are the fittest from a 50-country comparison? A systematic review with pooling of aggregate results. (5) Making a case for cardiorespiratory fitness surveillance among children and youth. (6) International normative 20-m shuttle run values from 1 142 026 children and youth representing 50 countries. (7) Temporal trends in the cardiorespiratory fitness of children and adolescents representing 19 high-income and upper middle-income countries between 1981 and 2014. Combined, this dissertation provides support for the importance of cardiorespiratory fitness for health surveillance among school-aged children and youth. Results from the international analysis highlighted the variability across countries, with countries in north-central Europe and Africa having the highest cardiorespiratory fitness, and countries in South America having the lowest cardiorespiratory fitness. The results indicated that declines in cardiorespiratory fitness may have stabilized in recent years in some high- and middle-income countries. This dissertation also identified 2 methods (criterion- and normative-referenced standards) to interpret cardiorespiratory fitness levels among children and youth, methods that could be used to inform future consensus, surveillance, and cardiorespiratory fitness guidelines.
越来越多的证据表明，心肺适能与学龄儿童和青少年的多个健康方面（即生理、身体、心理社会和认知）之间存在密切联系，而与身体活动无关。心肺适能是一种不会每天都有很大变化的特征，它可以反映近期的身体活动水平，因此是衡量人群健康的一个重要指标。因此，本论文的目的是研究使用 20 米往返跑测试测量的心肺适能作为儿童和青少年人群健康监测的广泛、整体健康指标的效用。为了实现这一目标，我们完成了 7 篇论文，全部准备提交给同行评议的科学期刊：（1）系统回顾 20 米往返跑表现与儿童和青少年健康指标之间的关系。（2）心肺适能的基准参考标准综述：1142026 名国际儿童和青少年中有多少人显然是健康的？（3）在一个大型的加拿大 8 至 12 岁儿童样本中，心肺适能与身体素养相关。（4）儿童和青少年 20 米往返跑表现的国际变异性：从 50 个国家的比较来看，谁是最健康的？系统回顾和汇总结果的汇总。（5）为儿童和青少年的心肺适能监测提供依据。（6）来自 50 个国家的 1142026 名儿童和青少年的国际标准 20 米往返跑值。（7）1981 年至 2014 年间，代表 19 个高收入和中上收入国家的儿童和青少年心肺适能的时间趋势。综合来看，本论文为学龄儿童和青少年的健康监测中心肺适能的重要性提供了支持。国际分析的结果强调了各国之间的差异，北欧和中欧以及非洲国家的心肺适能最高，而南美洲国家的心肺适能最低。结果表明，近年来，一些高收入和中等收入国家的心肺适能下降可能已经稳定下来。本论文还确定了两种解释儿童和青少年心肺适能水平的方法（基准和规范参考标准），这些方法可用于为未来的共识、监测和心肺适能指南提供信息。
