Background and Objective: Due to the disruption of the body’s natural posture because of the loss of interior arch of the foot in people with foot pronation, which may change amount and direction of forces and muscles electrical activity exerted on the foot during running movement, the purpose of this study was to compare ground reaction forces and muscles electrical activity of the ankle during running movement in young men with normal and pronation feet.

Materials and Methods: In this descriptive study, from male students of Physical Education and Sport Science in Khwarizmi University (2016), 15 people with pronated foot deformity and 15 healthy people were selected as subject. Force plate was used to measure ground reaction force. Surface electromyography signals were recorded during the running test by using an Electromyography that was simultaneous with force plate. To analyze data, MATLAB was used, and to describe data, mean and standard deviation were measured. Independent t-test was used to compare the two groups.

Results: The findings indicated there was a statistically significant difference in the medial-lateral direction between normal and pronated foot groups during the running movement in the variable of peak ground reaction force (p=.018). In the variable of muscles electrical activity during running, a significant difference was observed in the tibialis anterior (p=.02) and peroneus longus (p=.01) muscles between the two groups.

Conclusion: According to the results, it seems that foot pronation can be regarded as a factor affecting the biomechanics of side cut with a change in the medial-lateral ground reaction forces and muscles electrical activity during running movement.

Key words: Pronation of the foot, Ground reaction forces, Electrical activity of muscles, Running, Young men

Funding: There was no fund for this study.

Conflict of interest: None declared.

Ethical approval: The Ethics Committee of Kharazmi University approved the study.
