This study investigated the relationship between endurance performance and several measures of aerobic, anaerobic, and morphological fitness in 30 girls and 28 boys, 10 to 14 years of age. A multistage treadmill test was used for assessment of VO2 max (ml X kg-1 X min-1) and anaerobic threshold (AT) expressed both in absolute (AT-VO2) and relative (% VO2 max) terms. Anaerobic capacity (AC) was measured in a 30-s cycling task and expressed as kpm . kg of body weight-1 X min-1. Percent fat was estimated from skinfolds. The correlations between these measures and 2-km run time were: -0.73, -0.73, -0.50, -0.77, and 0.55 for VO2 max, AT-VO2, AT-%VO2 max, AC, and percent fat, respectively. When entered into a forward selection multiple regression with run time as the dependent variable, AC accounted for 59.5% of the variance and VO2 max accounted for an additional 6.9%, with AT and percent fat making no significant additional contribution. When the girls and boys were compared, no reliable differences were found for run time and AC. The boys exhibited reliably higher values for VO2 max and AT-VO2. No reliable difference in percent fat was found for the younger boys and girls, but the older girls were significantly fatter than the older boys. Thus, in children 10 to 14 there is a substantial relation between measures of anaerobic and aerobic function, although to some extent they provide independent information about endurance performance.(ABSTRACT TRUNCATED AT 250 WORDS)
本研究调查了30名10至14岁女孩和28名同龄男孩的耐力表现与有氧、无氧及形态适应性的多项指标之间的关系。采用多级跑步机测试来评估以绝对（无氧阈-最大摄氧量，AT-VO2）和相对（%最大摄氧量）形式表示的最大摄氧量（毫升·千克⁻¹·分钟⁻¹）和无氧阈（AT）。通过30秒的骑行任务测量无氧能力（AC），并以千克体重⁻¹·分钟⁻¹的千焦耳表示。通过皮褶厚度估算体脂百分比。这些指标与2公里跑步时间的相关性分别为：最大摄氧量为-0.73、AT-VO2为-0.73、AT-%最大摄氧量为-0.50、AC为-0.77、体脂百分比为0.55。当以跑步时间作为因变量进行向前选择多元回归分析时，AC解释了59.5%的方差，最大摄氧量额外解释了6.9%，无氧阈和体脂百分比没有显著的额外贡献。比较男孩和女孩时，在跑步时间和AC方面未发现可靠差异。男孩的最大摄氧量和AT-VO2值确实更高。在年龄较小的男孩和女孩中，体脂百分比未发现可靠差异，但年龄较大的女孩比年龄较大的男孩明显更胖。因此，在10至14岁的儿童中，无氧和有氧功能指标之间存在实质性关系，尽管在某种程度上它们提供了关于耐力表现的独立信息。（摘要截选至250字）
