A comparative analysis of leg morphology between sprinters and non-sprinters reveals surprising results

A comparative analysis of leg morphology between sprinters and non-sprinters reveals surprising results waseda_univ

Previous studies have revealed that sprinters have inhomogeneous muscular development, with well-developed hip flexors, extensors, and muscles located in the proximal thigh. The muscularity in sprinters corresponds well with the musculoskeletal demands for sprinting, which can be a positive aspect in force-related factors.mass distribution

This raises an interesting question: How do sprinters balance muscular strength and brisk movements? Contextually, not much is known regarding the maneuverability oflegs from an inertial viewpoint. This knowledge gap caught the attention of a research team led by Professor Yasuo Kawakami from the Faculty of Sport Sciences, Waseda University, who, along with his colleagues Hoshizora Ichinose from Nihon University and Dr.

These findings have been published inTo understand the trade-off between joint torque and segment maneuverability, the researchers further computed the moment of inertia of the lower limbs around the hip.
