ABSTRACT

Childhood physical fitness relative to adult health outcomes coupled with scant longitudinal research indicates that tracking of fitness components throughout childhood/adolescence is imperative. The study examined the stability/tracking of 9 measures of fitness for boys and girls at 5 points throughout childhood/adolescence. Tracking coefficients between individual fitness measures at various age comparisons were calculated. Using a sample with recorded data at 4 time-points, tertiles (high, moderate, low) were calculated for each fitness measure for boys and girls. Stability of fitness measures was calculated. Boys outperformed girls on fitness measures at most time points. Significantly low to moderately high tracking coefficients for each fitness measure at all time points for boys (r = .21-.79) and girls (r = .23-.89) were found. Tertile ratings remained stable across the 4 time-points. Findings highlight the importance of developing healthy fitness behaviors early in life and the significance of intervention during adolescence in low-fit youth.

摘要

与成人健康结果相关的儿童体能状况以及很少的纵向研究表明，追踪整个儿童期/青少年期的体能成分势在必行。该研究检查了在整个童年/青春期的5个点对男孩和女孩进行的9种健身测量的稳定性/追踪性。计算了各个年龄段的个人健身指标之间的跟踪系数。使用在4个时间点记录数据的样本，针对男孩和女孩的每种健身指标计算三分位数（高，中，低）。计算健身措施的稳定性。在大多数时间点上，男孩在健身方面的表现均优于女孩。在所有时间点，男孩的每项健身指标的跟踪系数均从低到中较高（r= .21-.79）和女孩（r = .23-.89）。在这四个时间点，三分评级均保持稳定。研究结果突出了在青少年早期发展健康健身行为的重要性以及在青春期进行干预的重要性。
