Biomimetic research on posture optimization of sprinters: Inspiration from high-speed moving organisms in nature

Biomechanics of sprinters’ posture is critical to maximizing speed and efficiency. Inspired by high-speed organisms in nature, such as cheetahs and falcons, this research examines biomimetic principles to optimize sprinters’ running posture. High-speed animals possess unique anatomical and mechanical traits, allowing remarkable acceleration, stability, and energy efficiency. These characteristics provide valuable insights into improving human sprinting performance. The investigation begins with an in-depth analysis of these organisms’ musculoskeletal systems and movement patterns, focusing on their body alignment, limb positioning, and force application during high-speed locomotion. This data is the foundation for developing biomechanical models applicable to human sprinters. The models are further validated through motion capture technology and simulations, where adjustments to sprinters’ postures are tested for speed, stride length, and energy efficiency improvements. Results from the experiments show a significant reduction in energy wastage and increased propulsion when sprinters adopt optimized postures inspired by natural high-speed organisms. Key adaptations include adjustments in trunk alignment, arm movement coordination, and lower limb force generation, closely mirroring the dynamic posture control seen in nature. This research demonstrates that adopting biomimetic insights leads to measurable sprinting efficiency and performance enhancements. The findings also contribute to developing training protocols for athletes, focusing on optimizing posture based on natural biomechanics.
