The forefoot longitudinal bending stiffness of shoe soles, measured through the widely used three-point test, is a key factor influencing running economy and lower-limb biomechanics. This study utilizes finite element method to simulate bending, examining influence different loading rates on analyzing impact various plate thicknesses curvature radii plates ‘plate-sole’ system. results indicate that within same displacement range, varying did not affect stiffness. However, increased thickness...
High long-term stress on the plantar fascia (PF) is main cause of fasciitis. Changes in midsole hardness (MH) running shoes are an important factor leading to alteration PF. This study aims establish a finite-element (FE) model foot-shoe, and investigates effects PF strain. The FE foot-shoe was built ANSYS using computed-tomography imaging data. Static structural analysis used simulate moment push stretch. Plantar strain under different MH levels were quantitatively analyzed. A complete...
Skateboarding is an Olympic event with frequent jumping and landing, where the cushioning effect by foot structure (from arch, metatarsals, etc.) damping performance sports equipment (shoes, insoles, can greatly affect athlete's lower risk of limb injury. characterized formation a "man-shoe-skateboard system," which makes its mechanism different from those other maneuvers, such as basketball vertical jump gymnastics broad jump. Therefore, it necessary to clarify upon landing on skateboard....
Abstract The influences of elevated and cryogenic temperature on the quasi‐static indentation responses damage mechanism for composite Y‐type cores sandwich structure were studied by experiments in present paper. performed to explore performances structures under eight different conditions. testing environment typical force‐deformation curves, patterns failure load investigated analyzed. experimental results demonstrated that made an important influence deformation mechanism, curves load....
The push-off angle is an important factor affecting speed-skating performance. However, quantitative evidence for the relationship between and foot injury incomplete. This study aimed to establish a three-dimensional (3D) finite element model (FEM) investigate mechanical responses of structures stress strain explore movement. A 3D FEM was reconstructed using CT scan data validated by comparing FEM-predicted in vivo measurement balanced standing state. obtained from video champion loaded into...
This study aimed to identify key biomechanical and physiological parameters affecting cross-country skiing performance develop a neural network model for predicting speed. Biomechanical attributes (cycle length rate, vertical displacement of the center mass, angular kinematics) factors (maximal oxygen uptake, 30 s anaerobic power), along with physical fitness (standing long jump, pull-ups) were assessed 82 skiers (52 men women). Random forest analysis was utilized most influential on speed,...
