Physics Of Martial Arts: Incorporation Of Angular Momentum To Model Body Motion And Strikes, Alexis Merk, Andrew Resnick

Physics Faculty Publications

We develop a physics-based kinematic model of martial arts movements incorporating rotation and angular momentum, extending prior analyses. Here, our approach is designed for a classroom environment; we begin with a warm-up exercise introducing counter-intuitive aspects of rotational motion before proceeding to a set of model collision problems that are applied to martial arts movements. Finally, we develop a deformable solid-body mechanics model of a martial arts practitioner suitable for an intermediate mechanics course. We provide evidence for our improved model based on calculations from biomechanical data obtained from prior reports as well as time-lapse images of several different kicks. …

Deception Of Resistance And The Effects On Muscular Fitness And Perceived Exertion, Tyler Mchenry

Electronic Theses and Dissertations

Resistance training has been a popular tactic that individuals have used to increase muscular fitness for decades. Muscular fitness includes muscular endurance, strength, and power. However, limitations such as self-efficacy and the Central Governor Theory may influence individual maximal performance ability. One training tactic that has been rarely researched is the deception of resistance during exercise, which is assumed to increase performances in all aspects of muscular fitness and improvements in perceived effort. Inconsistent results have been concluded from previous studies that have examined the same topic. Therefore, the purpose of this study was to investigate the effect of resistance …

Bilateral Ground Reaction Force Jumping Asymmetry And Performance, Keith Painter

Electronic Theses and Dissertations

The prevalence of asymmetry in performance research has increased in recent years with mixed results. Much of the performance research has focused on unilateral jumping activities attempting to show relationships to other performance variables. However, bilateral ground reaction forces (bGRF) from jumps are more frequently assessed in athlete monitoring programs and the asymmetry from those jumps could be a simple addition to data already being collected. Research into bGRF asymmetries is lacking and no studies have addressed longitudinal changes. Additionally, research into the relationship of asymmetries to performance have infrequently used athletes. For these reasons, this dissertation will focus on …
