Introduction: An increase in the peak vertical ground reaction force during running has been reported in overweight people, which can further disrupt mobility and quality of life. This research aimed to compare the frequency spectrum of the vertical ground reaction force in ten areas of the foot in overweight people compared to healthy people during running.
Methods: The current research was semi-experimental and applied research. Using G-Power software, the minimum sample size of 15 people was estimated for each group. The statistical sample of this research was made up of 30 teenagers in Ardabil province with an age range of 10 to 13 years. A foot scan device (RSScan) with a sampling rate of 300 Hz was used to record plantar pressure variables.
Results: The values of the essential harmony number of the big toe component, toes 2 to 5 component, first metatarsal bone component, and second metatarsal bone component in the overweight group were 31.37%, 40.03%, 32.12%, and 33/49%, higher compared to the healthy group. The median frequency in the component of the big toe in the healthy group was 20.94% higher than in the overweight dry group. The frequency values with a power of 99.5% of the third metatarsal bone component in the overweight group were 15.57% higher than the healthy group.
Conclusion: According to the results obtained in this research, it can be concluded that overweight children have more fluctuation during running compared to their healthy peers, which can increase the possibility of injury in these children.
