ISBS Online Vorlesungsreihe

Die Sports Biomechanics Lecture Series wurde von Dr. Stuart McErlain-Naylor im Namen der International Society of Biomechanics in Sports organisiert. Die von Vicon gesponserte Reihe umfasst 28 Vorträge über die Biomechanik spezifischer Sportarten sowie über biomechanische Datenerfassungs- und Analysetechniken. Das ursprüngliche Ziel des Projekts war es, Ressourcen bereitzustellen, um den Online-Unterricht und die weitere Erforschung von Biomechanik-Themen für Studenten und Doktoranden zu erleichtern.

Bitte beachtet, dass alle Vorlesungen in englischer Sprache abgehalten wurden.

Alasdair Dempsey covers the biomechanics behind anterior cruciate ligament (ACL) injury mechanisms, with reference to underlying mechanical principles such as moments and moment arms. He also discusses the evidence behind potential intervention strategies.

Paul Felton discusses the scientific literature on the topic of cricket bowling biomechanics. He covers both fast bowling and spin bowling, with reference to the underlying mechanical principles of linear and angular momentum, and conservation of momentum. Paul also presents a kinematic comparison of male and female bowlers.

Stuart McErlain-Naylor discusses the scientific literature on the topic of cricket power hitting biomechanics. Topics include: a) the effect of impact location (e.g. sweetspot) on shot outcome (e.g. carry distance, ball launch angle, ball launch speed); b) the kinematic technique parameters most associated with variation in power hitting performance; c) a kinematic comparison of male and female international batters; and d) a comparison of batting kinematics against different delivery methods (bowler / bowling machine / SidearmTM) with reference to representative training design.

Johannes Funken presents a comparison of elite long jump biomechanics between athletes with and without a below the knee prosthesis. This comparison includes both kinetic and kinematic parameters. Discussions include whether athletes with a below the knee prosthesis are at an advantage or a disadvantage.
