Abstract:
Foot rollover and the 'ride' feeling that occurs during heel-toe transition during running have been investigated mostly in laboratory settings due to the technical requirements of 'golden standard' measurement devices. Hence, the purpose of the current study was to investigate 'ride' and rollover with a heel cap-mounted inertial measurement unit (IMU) when running under field conditions to get realistic results. Twenty athletes ran on a 1 km outdoor track with five different shoe conditions, only differing in their midsole bending stiffness. The peak angular velocity (PAV) in the sagittal plane of the shoe was analyzed. The subjective evaluation of the 'ride' perception during heel-toe transition was rated on a visual analogue scale. The results revealed that PAV and 'ride' varied for the different shoes. The regression analysis showed that PAV has a significant impact on the 'ride' rating (R2 = 0.952; p = 0.005). The shoe with a medium midsole bending stiffness had the lowest value for PAV (845.6 deg/s) and the best rating of perceived 'ride' on average. Our results show that IMU can be used as a low-cost method to investigate the heel-toe transition during field-running. In addition, we found that midsole bending stiffness influenced PAV and the subjective feeling of 'ride'.

Measuring Acceleration Due to Gravity
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...

For instance, imagine a hard cylinder rolling on a comparatively soft surface. The cylinder's weight compresses the surface beneath it. As the cylinder moves, the material in front of it slows down...
