Abstract

Highlights: There is a positive effect of increased running intensity on increasing the maximal angle of pronation. An increase in the running intensity exposes the individual to pronation beyond that considered normal. Runners with low control of conditions and training environment will be more prone to the appearance of joint injuries from hyperpronation. Abstract: The purpose of this study was to investigate the behavior of foot pronation at different percentages of peak velocity in 23 physically active men. An ergospirometric test was carried out with an initial velocity of 9 km h −1 and increments of 1 km h −1 until exhaustion. 2D kinematic analysis was performed in the posterior frontal plane at all velocities to identify the maximal angle of pronation (MAP) of the right leg. The analyses were performed between the initial periods (0%), 25%, 50%, 75%, and 100% (peak of velocity — PV). All comparisons of the PV phases with the MAP showed an increase in the angle of foot pronation, with the exception of between the start and 25% of PV. Only 4 (∼17%) subjects maintained MAP values within a normal range until PV was reached. Control of the volume and intensity of training, as well as the running technique is suggested and strengthening of the muscles responsible for stabilization of the foot pronation.
