★Associate Professor Maemura and Ph.D. student Muratomi have published a study in the Scandinavian Journal of Medicine & Science in Sports.
In 400-m sprinting, achieving high performance requires economical running techniques that allow sprinters to produce large stride length with minimal mechanical work. However, the morphological characteristics underlying such techniques have remained unclear.
This study revealed that a smaller cross-sectional area (CSA) ratio of the lower leg to the thigh is associated with increased thigh swing velocity and contributes to more economical running mechanics. These findings suggest that the relative size of proximal muscles plays a critical role in supporting efficient sprinting techniques in 400-m sprinters.
