Treadmill Deck Performance Optimization Design Based on Muscle Activity during Running

In previous research on treadmills, the main focus has been comparing physiological differences induced by running treadmill decks and other exercise surfaces, with relatively little mechanical properties of decks. Reducing sports injuries is a common desire runners, which may be closely related to muscle activity. Obviously, play an important role in this process. Muscle activity was evaluated based mass-spring-damper (MSD) model that provides simulated signal ground reaction forces (GRF) vibration lower-limb soft tissues (LLST) during landing human body running. We improved original motion considering stiffness damping effect deck. addition, theory regulation, dimensionless objective function established, particle swarm optimization algorithm used find best range deck parameters under pre- post-fatigue conditions. The results show hardness can affect regulation Based this, specific safe area are obtained, size after fatigue significantly reduced compared before fatigue. By studying effects expected provide references for design reduce risk runners’ injuries, practical application value health.
