Relationship between Eye-foot Coordination and Lower Abdominal Core Stability among Young Individuals Based on BMI

Abstract

Background: Eye-foot coordination and core stability are essential components of functional movement and athletic performance, yet their interrelationship across varying Body Mass Index (BMI) categories remains underexplored. This study investigates the correlation between eye-foot coordination and lower abdominal core stability in young individuals based on BMI classification. Methods: An observational study was conducted among 108 participants aged 18–25 years. Core stability was evaluated using the Sahrmann Five-Level Core Stability Test, while eye-foot coordination was measured using the Soccer Wall Volley Test. Pearson correlation analysis was performed across BMI categories to assess associations. Results: A significant positive correlation was found between eye-foot coordination and core stability (r = 0.800, p < 0.001), with consistent findings across BMI groups, underweight (r = 0.791), normal (r = 0.791), and overweight (r = 0.821). Overweight individuals demonstrated slightly higher coordination and stability levels. Conclusion: These findings highlight the synergistic role of neuromuscular coordination and abdominal control in enhancing movement efficiency, irrespective of BMI. Targeted interventions integrating core strengthening and coordination training may improve functional performance among young adults.
