biomechanical patterns and insufficiencies that may influence risk of ligamentous injury, such as an anterior cruciate ligament (ACL) tear. One kinematic pattern that has been identified as detrimental to ACL integrity is frontal plane knee collapse (valgus) during jumping and landing tasks.1 Inter-limb differences in force generation have also been connected to the occurrence of lower extremity injury.2 It is not known, however, whether these patterns contribute to the occurrence of lower extremity (LE) non-contact soft-tissue injury. The counter-movement vertical jump (CMVJ) is one way to simultaneously screen for knee collapse and asymmetrical force production patterns. This method was therefore …

Biomechanical Investigation Of Elite Place-Kicking, Chase M. Pfeifer

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Many studies aim to understand the fundamentals of kicking commonly displayed by soccer players [4,6,10,16,17,18,24,25,28,29,30,34,36,38,40]. Of those studies, most are limited to a two-dimensional (2D) analysis using high-speed cameras for position tracking or utilizing electromyography to observe the activity of select muscles [4,6,18,25,29,36]. The few studies that investigate kicking using a three-dimensional (3D) model are limited in their position tracking capabilities and focus mainly on joint flexion potentials and foot speed.

This dissertation is a comprehensive biomechanical analysis (kinematic and EMG) of the field-goal place-kicking techniques of four elite kickers in American football. Data were compared and contrasted with ball …
