Abstract: (43 Views)
Introduction: Obesity is a global health concern that can lead to significant changes in mechanical components in individuals compared to healthy counterparts. This study aimed to investigate the effect of fatigue on the mechanical components of impulse and center of pressure in individuals with obesity and pronated feet during walking and running.
Methods: This was a semi-experimental study involving 31 students from Ardabil Province, divided into two groups: 16 healthy individuals and 15 individuals with obesity and pronated feet. Mechanical values were recorded before and after a fatigue protocol using a force plate device (sampling rate 1000 Hz) during barefoot walking and running. Statistical analysis was conducted using a two-way analysis of variance with repeated measures. The study was approved by the Ethics Committee of the University of Mohaghegh Ardabili (IR.UMA.REC.1403.062).
Results: The effect of group membership on the mechanical values of impulse along the vertical axis (P < 0.007), impulse along the anterior-posterior direction (P < 0.003), and the center of pressure along the medial-lateral direction showed statistically significant differences between the two groups (P < 0.029).
Conclusion: There are significant changes in the mechanical components of impulse along the vertical axis, impulse along the anterior-posterior direction, and the center of pressure along the medial-lateral direction in individuals with obesity and pronated feet during walking and running.
