Head Motion In Overarm Throwing For Children With Varying Levels Of Motor Proficiency, Kevin J. Netto
Theses : Honours
The overarm throw has been classified as a fundamental motor skill that is the basis for a number of more complex sporting skills. There are a number of developmental stages over which a child progresses to the mature form of the skill. Control of the overarm throw, especially towards a target is very dependent on visual and vestibular information for successful execution. The quality of the information is, in tum, dependant on the head movement of the performer during the execution of the skill. It has been reported that head angular velocities above 350 degrees/second result in a degradation of …

Head Stabilisation During Running In Place Of Children With Varying Motor Proficiency Levels, Craig Atkins
Theses : Honours
Understanding head motion in children may contribute to development of effective strategies to improve coordination of children. The purpose of this study was to investigate head motion in children during stationary running. Twelve healthy 8-year-old children participated in this study and underwent a running proficiency test based on the Test for Gross Motor Proficiency (TGMO). Subjects were then videotaped while running for one minute "on the spot". Reflective markers were digitised for analysis of head motion relative to the external environment, and relative to the trunk. Resultant and component head angular velocities were calculated for each subject over five consecutive …
