Leg- and joint stiffness in male elite high jump: the influence of stiffness on sports performance

Abstract

The purpose of this study was to analyse stiffness in the mechanical system of the world’s elite high jumpers. Seven male elite high jump athletes (personal best 2.24 m ± 0.06 m) were filmed with 19 Infrared-High-Speed-Cameras during jumping. Kinetics were captured with a force plate. It was found that a different leg and joint stiffness during take-off enables nearly the same jumping height. For example, a typical power jumper with a leg stiffness of 543.6 Nm-1kg-1 reached 2.13 m, while a typical speed jumper with a leg stiffness of 1133.5 Nm-1kg-1 reached a comparable height of 2.12 m. Therefore, it seems that sports performance in single leg jumping is not limited by athlete’s leg and joint stiffness in a small group of male elite high jumpers.
