Biomechanics Analysis of Different Angle of Sole’s Toe-Box Region during Walking and Jogging

Abstract

This study aims to investigate the kinematics and kinetics of wearing of the different height of shoe toe box walking and jogging. A total of 20 normal males participated in the experiment controlling the jogging speed of 8 km/h and the walking speed of 4 km/h. The Vicon three dimension motions analysis system was taken to capture the kinematics of lower extremity while jogging and walking text. The Novel Pedar-X insole plantar pressure measurement system was utilized to collect the plantar pressure in specific anatomical areas. The function of toe box regions is analyzed through the comparison of plantar pressure parameters and kinematic results. They performed both texts under four conditions which is common sneaker (A), sneaker of Marathon (B), flat sneaker (C) and specially customized sneaker (D). During the walking phase, the ankle of C showed significantly less peak plantar flexion than other shoes. During the jogging phase, the ankle for D showed significantly larger peak flexion than other shoes, and the C is smallest. Meanwhile, the ankle and knee of all shoes expressed different changes in the sagittal and frontal plane. The D of peak pressure and pressure-time integral are obviously higher than other shoes in BT and LFF area. The contact time of D and other shoes exist significant differences in jogging. Compare to wearing different height of shoe box sneakers, the D shoe wearer may enhance BT and forefoot areas power and proprioceptive, to improve athletic performance and to keep balance. The C shoe does not fit sport because it’s having more larger plantar pressure in most of the foot region than other shoes, easy to cause the injury of lower limbs. The A and B shoes are no sensible difference in jogging and walking.
