Kinematic and Kinetic Effects of Ultra-Lightweight Running Shoes on Performance, Fatigue, and Biomechanical Efficiency

Abstract

Ultra-lightweight running shoes (ULRS) are designed to improve running performance by reducing metabolic cost, optimizing kinematics, and reducing fatigue. This study investigates the effects of ULRS on biomechanical efficiency, running economy, and fatigue resistance. Using a comparative study of trained runners, we analyze kinematic and kinetic parameters, including stride length, ground reaction forces (GRF), and muscle activation. The findings indicate a significant improvement in running performance with ULRS, though biomechanical trade-offs exist.
