Abstract des Autors
The purpose of the study was to evaluate kinematics and kinetics in elite high jumpers and to estimate joint work of the lower extremity with a custom-modified full-body model. Motions of seven male athletes (personal best 2.24 ± 0.06 m) during jumping were filmed with 19 Infrared-Highspeed-Cameras and ground reaction forces were captured with a force plate. The results show that knee joint energy absorption is twice as much as at the ankle joint (p < 0.05). There was no significant difference (p > 0.05) in energy generation between the knee and ankle joint, but the ankle joint generates more energy than it absorbs (p < 0.05). The problem-solving approach to raise the center of mass to 2.10 m was different between the jumpers.
