Forefoot Centre of Pressure Patterns in Black Male African Recreational Runners with Pes Planus
Jodie Dickson, Glen James Paton, Yaasirah Mohomed Choonara

TL;DR
This study examines how pes planus affects foot pressure patterns in Black African male runners, finding unexpected lateral pressure shifts that challenge traditional assumptions.
Contribution
The study provides novel insights into the biomechanics of pes planus in Black African recreational runners, challenging conventional views of overpronation.
Findings
Lateral displacement of the center of pressure was observed in most participants' right and left forefeet.
Flexible pes planus was significantly more common than rigid pes planus among participants.
Load distribution patterns differed between the right and left feet, with distinct preferences for medial and lateral regions.
Abstract
Background: Pes planus is a condition where the arch of the foot collapses, resulting in the entire sole contacting the ground. The biomechanical implications of pes planus on gait have been widely studied; however, research specific to Black African populations, particularly recreational runners, is scarce. Aim: This study aimed to describe the forefoot centre of pressure (CoP) trajectory during the barefoot gait cycle among Black African recreational runners with pes planus. Methods: A prospective explorative and quantitative study design was employed. Participants included Black African male recreational runners aged 18 to 45 years diagnosed with pes planus. A Freemed™ 6050 force plate was used to collect gait data. Statistical analysis included cross-tabulations to identify patterns. Results: This study included 104 male participants across seven weight categories, with the majority…
