AB Purpose: This study assessed the impact of different types of medial foot arch on posturalstability and core center of gravity muscle activity among collegiate athletes. Methods: The studysample included 103 university-level athletes across various sports (soccer, rugby, basketball, volleyball,field tennis, table tennis, karate, and cheerleading) from the College of Magdalena (Colombia)who exhibited distinct types of medial foot arch: 32 high, 35 low, and 36 neutral arches. Surfaceelectromyography (sEMG) was employed to assess conduction velocity, magnitude values, latency,and fatigue in focal muscles including the spinal erector (SE), internal oblique (IO), external oblique(EO), and rectus abdominis (AR), while measurements of static and dynamic postural control werealso considered. Post hoc analysis was performed with Bonferroni correction for all electromyographicallymeasured muscle groups, as well as for measurements of static and dynamic posturalstability. Pearson’s or Spearman’s correlation tests were used to compare the different types offeet. Results: There were no substantial differences observed between the distinct types of feet interms of focal muscle activity, static stability, or dynamics. Even though the mean values indicatedhigher muscle activity and stability among those with high foot arches and lower values amongthose with low arches compared to the neutral foot type, this observed difference was deemedstatistically insignificant. We also observed a positive correlation between internal oblique muscleactivity and the average power of dynamic postural stability, which remained consistent across allfoot types. Our findings indicate that static instability is directly correlated with dynamic instabilityin the anteroposterior direction, while a clear inverse relationship was established in the lateraldirection upon examining the variable correlations. Conclusions: The presence of high or low footarches did not significantly impact the activity of the muscles responsible for maintaining the body’scenter of gravity or postural stability among university-level athletes. This suggests the existence ofneuromuscular compensation mechanisms that attempt to restore balance and compensate for anychanges in postural stability caused by varying foot types. Through targeted training that emphasizesactivation of the internal oblique muscle, athletes may see improved postural stability. Our findingsindicate that static stabilization exercises can also prove beneficial in improving dynamic stabilityin the anteroposterior plane, while a more dynamic approach may be required to improve dynamicstability in the lateral plane.
