OBJECTIVE To establish the prevalence of domestic violence committed by women against male patients presenting to an urban ED for any reason. METHODS This was a prospective survey in which male patients of legal age presenting to the ED over a 13-week period were interviewed. Patients answered a series of six questions adapted from the George Washington University Universal Violence Preventio...

Accurate goal-kicking is important to a team’s success in Australian Football (AF). However, it remains a largely unexplored area in sport biomechanics. This study examined technical aspects of goal-kicking accuracy using an inertial measurement system (IMS). Two junior AF players performed 15x20m goal-kicks in the field. Kinematics were measured using the Xsens MVN link IMS (240Hz). Results sh...

Xavier is an eight-year-old American boy of Italian ancestry in a second-grade inclusion classroom at a public elementary school. He carries diagnoses of a severe language-based learning disorder (LD) and attention-deficit/hyperactivity disorder (ADHD). He lives with his mother, twin sister, and older teenage brother; his parents are in the process of divorcing. The Office of Special Education ...

A dual-task paradigm was implemented using a repeated measures design to determine the time course of attention demands during performance of a soccer penalty kick. Experienced soccer players (N=15) were asked to perform a 12-yard soccer-style penalty kick. As part of the dual task paradigm, participants were instructed to respond to an audible cue that was administered during one of three prob...

This article reviews developments in the use of Artificial Intelligence (AI) in sports biomechanics over the last decade. It outlines possible uses of Expert Systems as diagnostic tools for evaluating faults in sports movements ('techniques') and presents some example knowledge rules for such an expert system. It then compares the analysis of sports techniques, in which Expert Systems have foun...

SKILL LEARNING BASED CATCHING MOTION CONTROL Gökçen Çimen M.S. in Computer Engineering Supervisor: Assist. Prof. Dr. Tolga Kurtuluş Çapın July, 2014 In real world, it is crucial to learn biomechanical strategies that prepare the body in kinematics and kinetics terms during the interception tasks, such as kicking, throwing and catching. Based on this, we presents a real-time physics-based approa...

We investigate the dynamics of a kicked particle in an infinite square well undergoing frequent measurements of energy. For a large class of periodic kicking forces, constant diffusion is found in such a non-Kolmogorov-Arnol'd-Moser system. The influence of a phase shift of the kicking potential on the short-time dynamical behavior is discussed. The general asymptotical measurement-assisted dif...

BACKGROUND Kicking performance is the most studied technical action in soccer and lower limbs kinematics is closely related to success in kicking, mainly because they are essential in imparting high velocity to the ball. Previous studies demonstrated that soccer leagues in different countries exhibit different physical demands and technical requirements during the matches. However, evidencewhet...

BACKGROUND The most utilized soccer kicking method is the instep kicking technique. Decreased motion in spinal joint segments results in adverse biomechanical changes within in the kinematic chain. These changes may be linked to a negative impact on soccer performance. This study tested the immediate effect of lumbar spine and sacroiliac manipulation alone and in combination on the kicking spee...

Throwing is a major behavioral component of hominid evolution. Comparison of this behavior across a broad range of non-human primate species is needed to elucidate the phylogenetic constraints on throwing behavior. In this study of stone-throwing in Japanese macaques, we present a systematic multi-group comparison of the frequency and prevalence of this behavior as well as detailed descriptions...
