The purpose of this study was to empirically test a comprehensive conceptual model linking gross motor skills, school day physical activity and health-related variables in a sample of sixth graders. Participants were a convenience sample of 84 sixth grade students (Mean age = 11.6 ± 0.6 years). Gross motor skills were assessed using the Test of Gross Motor Development-3rd Edition (TGMD-3), school day physical activity was assessed using pedometers, health-related fitness was assessed using Progressive Aerobic Cardiovascular Endurance Run (PACER) laps, perceived competence assessed using a validated questionnaire and the health-related outcome was assessed using Body Mass Index (BMI). The relationship between school day step counts and TGMD-3 scores was mediated through both perceived competence and PACER laps ( = 0.015) and the direct path coefficient between TGMD-3 scores and BMI was statistically significant ( = -0.22 kg/m, < 0.001). Overall there was good model fit with all indices meeting acceptable criteria ( = 3.7, = 0.293; Root Mean Square Error of Approximation (RMSEA) = 0.062, 90% Confidence Interval (C.I.): 0.00-0.23; Comparative Fit Index (CFI) = 0.98; Tucker-Lewis Index (TLI) = 0.96; Standardized Root Mean Square Residual (SRMR) = 0.052). The comprehensive conceptual model explaining the inter-relationships among motor competence and health-related variables was empirically validated with the relationship between physical activity and gross motor skills mediated through both perceived competence and cardiorespiratory endurance in a sample of sixth graders.
本研究的目的是对一个全面的概念模型进行实证检验，该模型将六年级学生样本中的大肌肉运动技能、在校日身体活动和健康相关变量联系起来。参与者是84名六年级学生的便利样本（平均年龄 = 11.6 ± 0.6岁）。使用《大肌肉运动发展测试第三版》（TGMD - 3）评估大肌肉运动技能，使用计步器评估在校日身体活动，使用渐进性有氧心血管耐力跑（PACER）圈数评估健康相关体能，使用经过验证的问卷评估自我感知能力，并使用体重指数（BMI）评估健康相关结果。在校日步数与TGMD - 3分数之间的关系通过自我感知能力和PACER圈数介导（ = 0.015），TGMD - 3分数与BMI之间的直接路径系数具有统计学意义（ = -0.22 kg/m， < 0.001）。总体而言，模型拟合良好，所有指标均符合可接受标准（ = 3.7， = 0.293；近似均方根误差（RMSEA） = 0.062，90%置信区间（C.I.）：0.00 - 0.23；比较拟合指数（CFI） = 0.98；塔克 - 刘易斯指数（TLI） = 0.96；标准化均方根残差（SRMR） = 0.052）。在六年级学生样本中，通过自我感知能力和心肺耐力介导身体活动与大肌肉运动技能之间的关系，对解释运动能力与健康相关变量之间相互关系的综合概念模型进行了实证验证。
