Fundamental motor skill development during this stage directly influences the nervous system\u2019s growth. Motor coordination ability serves as the foundation for children\u2019s physical fitness, health, and motor performance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study investigates the relationship between motor coordination and health-related fitness in preschool children, analyzing the extent of motor coordination\u2019s impact on physical fitness. Through principal component analysis (PCA) and cluster analysis, differences in motor coordination and fitness performance across child populations are identified, providing theoretical support for optimizing health promotion strategies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Participants included 358 preschool children from a kindergarten in Weifang, Shandong, China., including demographic data such as parental education, socioeconomic background, and habitual physical activity participation collected via parent questionnaires to provide contextual information Motor coordination was assessed using the Movement Assessment Battery for Children-2 (MABC-2), while fitness tests (e.g., standing long jump, tennis throw, 10-meter shuttle run) were standardized into Z-scores. Statistical analyses included Pearson correlation, hierarchical regression, PCA, and cluster analysis. PCA component retention was based on eigenvalues &amp;gt;1 and scree plot inspection, while cluster validity was confirmed using the elbow method and silhouette coefficients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Motor coordination showed significant positive correlations with flexibility, strength, agility, and endurance. Hierarchical regression confirmed motor coordination\u2019s independent and significant influence on fitness outcomes, particularly in standing long jump and shuttle run. BMI exhibited a weak negative correlation with motor coordination. PCA revealed two principal components (Dim1: 31.7% variance, dominated by running and jumping; Dim2: 16.1% variance, emphasizing flexibility and tennis throw). Cluster analysis categorized children into three groups: \u201cComprehensive Excellence,\u201d \u201cAgility Specialization,\u201d and \u201cBasic Skill Needs.\u201d<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Motor coordination plays a pivotal role in preschool children\u2019s fitness development, particularly in agility and strength. PCA and cluster analysis highlighted distinct group differences, supported by validated retention and validation procedures, underscoring the need for targeted interventions to enhance motor
