To study the impact of crawling before walking (CBW) on network interactions among body composition, the cardiovascular system, lung function, motor competence and physical fitness, at age 7, and to assess the longitudinal association between CBW and body composition, the cardiovascular system, lung function, motor competence, physical fitness and physical activity parameters, at age 7.
CBW, body composition, cardiovascular system, lung function, motor competence, physical fitness and physical activity were assessed in seventy-seven healthy Caucasian children.
Network analyses revealed that the crawling group had a greater number of links among all the studied variables compared with the non-crawling group. In the longitudinal study, using multiple regression analyses, crawling was independently associated with fat mass (%), fat-to-muscle ratio and systolic blood pressure, with models explaining up to 56.3%, 56.7% and 29.9% of their variance, respectively.
CBW during child's development is a possible modulator in the network interactions between body systems and it could influence future metabolic and cardiovascular health.
研究在 7 岁时爬行前行走（CBW）对身体成分、心血管系统、肺功能、运动能力和身体素质之间的网络交互的影响，并评估 CBW 与身体成分、心血管系统、肺功能、运动能力、身体素质和身体活动参数在 7 岁时的纵向关联。
对 77 名健康的白种人儿童进行 CBW、身体成分、心血管系统、肺功能、运动能力、身体素质和身体活动的评估。
网络分析显示，与非爬行组相比，爬行组所有研究变量之间的联系更多。在纵向研究中，使用多元回归分析，爬行与体脂肪（%）、脂肪与肌肉比和收缩压独立相关，模型分别解释了 56.3%、56.7%和 29.9%的变异。
儿童发育过程中的 CBW 可能是身体系统之间网络交互的调节因素，可能会影响未来的代谢和心血管健康。
