Video analysis of the deformation and effective mass of gymnastics landing mats

Article Abstract:

The effective mass, shock transmission time, and deformation characteristics of a mat during impacts using high-speed video was determined to improve the accuracy of measuring foot-mat contact forces during landing. The acceleration estimates obtained from high-speed video were combined with the effective mass estimates from the volume calculation to give peak calculated forces at the bottom of the mat to -1.1 to +3.7% of the force recorded through the force plate.

Surface effects on ground reaction forces and lower extremity kinematics in running

Article Abstract:

This article examines changes in biomechanical and kinematic responses of heel-to-toe runners due to impact absorption adjustments in running surfaces. Results indicate that there were no significant differences in peak impact force measurements across the three different surfaces due to lower extremity kinematic adjustments in runners.

Biomechanical analysis of running in military boots with new and degraded insoles

Article Abstract:

Research reveals that mechanical degradation of insoles increase in mechanical stiffness and mechanical impact. However, during running one insole type reduced peak impact loading when new, which is maintained even after mechanical degradation. Furthermore, it also reduced peak ankle dorsiflexion.
