To examine longitudinal (seven years) relationships among cardiorespiratory fitness (VO), body fatness, and motor competence.
Data were collected as part of the Copenhagen School Child Intervention Study (CoSCIS). Body fatness was assessed by the sum of four skinfolds. VO was measured directly in a continuous running protocol. Motor competence was assessed using the Körperkoordinationtest für Kinder. This study used multilevel linear mixed models to evaluate the reciprocal longitudinal association between body fatness, VO, and motor competence. All regressions were stratified by sex and adjusted by intervention and pubertal status. All variable coefficients were standardized.
A reciprocal relationship was observed between children's motor competence with body fatness and VO at the seven-year follow-up (6-13 years of age). Children with higher motor competence at baseline had a lower risk of having higher body fatness (β=-0.45, 95% CI: -0.52 to -0.38; β=-0.35, 95% CI: -0.42 to -0.28) and higher VO (β=0.34, 95% CI: 0.27-0.40; β=0.27, 95% CI: 0.20-0.33) during childhood. Alternatively, higher body fatness or lower levels of VO at baseline were associated with lower motor competence during childhood.
These data suggest motor competence, body fatness, and VO demonstrate reciprocal relationships across childhood (6-13 years of age). Interventions addressing motor competence, cardiorespiratory fitness, and body fatness in early childhood are recommended, as intervention effects are likely to be enhanced because of the mutual reciprocal associations between these three variables.
探讨心肺适能（VO）、体脂和运动能力之间的纵向（七年）关系。
数据来自哥本哈根儿童干预研究（CoSCIS）。体脂采用四个皮褶厚度之和进行评估。VO 通过连续跑步方案直接测量。运动能力采用儿童身体协调测试（Körperkoordinationtest für Kinder）进行评估。本研究使用多层次线性混合模型来评估体脂、VO 和运动能力之间的相互纵向关联。所有回归均按性别分层，并根据干预和青春期状态进行调整。所有变量系数均标准化。
在七年随访（6-13 岁）时，观察到儿童运动能力与体脂和 VO 之间存在相互关系。基线时运动能力较高的儿童，体脂较高的风险较低（β=-0.45，95%CI：-0.52 至-0.38；β=-0.35，95%CI：-0.42 至-0.28），VO 较高的风险较低（β=0.34，95%CI：0.27-0.40；β=0.27，95%CI：0.20-0.33）。相反，基线时体脂较高或 VO 水平较低与儿童期运动能力较低相关。
这些数据表明，运动能力、体脂和 VO 在整个儿童期（6-13 岁）表现出相互关系。建议在儿童早期进行针对运动能力、心肺适能和体脂的干预，因为由于这三个变量之间的相互相互关联，干预效果可能会增强。
