The classical stretch shortening cycle (SSC) describes sagittal joint flexion–extensions in motions like running or hopping. However, lateral movements are integral components of team sports and are associated with frontal plane joint displacements. The purpose of this study is to identify neuromuscular and kinematical mechanisms determining motor control(More)
Load-dependant adjustments in lateral jumps are thought to rely on foot placement and on upper leg’s kinematic and neuromuscular adaptations. The aim of this study was to elucidate task-specific adjustments during the initial impact phase under varying stretch-loads by the comparison of lateral jumps and lateral landings. Ten subjects performed lateral(More)
BACKGROUND Gender and fatigue are thought to affect the anterior cruciate ligament injury risk. In spite of much effort, the influence of these factors on knee joint biomechanics is still under discussion. The purpose of this study was to investigate kinematics, kinetics, and active muscle control strategies of the knee joint across gender in fatigue(More)
AIM Sledge jump systems (SJS) are often employed to examine the underlying mechanical and neuromuscular mechanisms of the stretch-shortening cycle (SSC) as they allow the systematic variation of impact velocity and energy. However, in existing SJS the jumps are not very comparable to natural jumps because of the long contact times (∼200%), which prevent the(More)
Noncontact injuries frequently occur during soccer matches and training. The purpose of this study was to examine the influences of different soccer shoe studs to kinematic, kinetic and electromyographic parameters in the knee joint. Six male soccer players performed complex turning movements (180 degrees ) with bladed and round studded soccer shoes. Ground(More)
Die für den chronisch Leberkranken zumeist schicksalsbestimmende portale Hypertension (PH) überschreitet bereits bei chronischer Hepatitis weit die oberen Grenzwerte. Mit Hilfe der laparoskopischen transhepatischen Manometrie (LTM) in den Ästen der V. portae und V. hepatica ermittelten wir bei chronisch-persistierender Hepatitis (CPH) Pfortaderdrucke von(More)
BACKGROUND Despite massive research efforts, it remains unclear how mechanical ankle instability (MAI) and functional ankle instability (FAI) affect joint control in the situation of ankle sprain. Thus, the purpose of this study was to evaluate whether individuals with MAI have deficits in stabilising their ankle joint in a close-to-injury situation(More)
Laparoscopic transhepatic measurement of pressures in the branches of the portal vein (and hepatic vein) were performed in 42 patients with hepatitic cirrhosis of the liver and compared with those obtained in patients with other defined causes of cirrhosis (alcohol, pigment, Budd-Chiari syndrome, right heart failure). Mean portal vein pressure was 27.2,(More)
Drop jumps and their adaptations to training have been extensively investigated. However, the influence of augmented feedback (aF) on stretch-shortening cycle (SSC) was not scrutinized so far despite the well-known positive effects of aF on motor performance and motor learning. The aim of the present study was therefore to investigate the effects of aF by(More)
BACKGROUND Chronic ankle instability (CAI) is a term that is not well defined until now in spite of a large body of respective literature. Most frequently this umbrella term is used synonymously for functional ankle instability and the role of the mechanical component is not fully understood.
