The developmental histories of 32 players in the Australian Football League (AFL), independently classified as either expert or less skilled in their perceptual and decision-making skills, were collected through a structured interview process and their year-on-year involvement in structured and deliberate play activities retrospectively determined. Despite(More)
The aim of this study is to investigate the effects of in-game physical exertion on decision-making performance of Australian football umpires. Fifteen Australian football umpires (Mage = 36, s = 13.5 years; Mgames umpired = 235.2, s = 151.3) volunteered to participate in the study. During five competitive Australian football pre-season games, measures of(More)
The aim of this study was to verify if yo-yo intermittent recovery test (level 2) (yo-yo IR2) score is linked to Australian football (AF) performance through match exercise intensity. Six week prospective study design. Twenty-one data sets were recorded from nine individual players that completed the yo-yo IR2, and played an Australian Football League match(More)
The aim of this study was to compare the effect of 2 repeated sprint training interventions on an intermittent peak running speed (IPRS) test designed for Australian Rules football. The test required participants to perform 10 × 10-m maximal efforts on an 80-m course every 25 seconds, for each of which the mean peak speed (kilometers per hour) was recorded(More)
INTRODUCTION In motor development literature fundamental movement skills are divided into three constructs: locomotive, object control and stability skills. Most fundamental movement skills research has focused on children's competency in locomotor and object control skills. The first aim of this study was to validate a test battery to assess the construct(More)
PURPOSE Pharmacy claims data is often used in pharmacoepidemiology studies, but no studies to date have examined whether it was possible to identify the use of blister packs in these databases. We aimed to determine whether medications dispensed in days divisible by 7 are more likely to be blister packed than medications dispensed in other quantities. (More)
OBJECTIVES Internationally, children's movement competence levels are low. This study's aim was to evaluate the effectiveness of a 16 week gymnastics curriculum on stability, locomotive and object control skills and general body coordination. It was hypothesised that the gymnastics intervention group would demonstrate significant improvements beyond a PE(More)
In 2005, an estimated $315.4 billion was spent worldwide on dementia care (Wimo, Winblad & Jonsson, 2007). Individuals seeking dementia care cost 3.2 times more than other older adults and are hospitalized 3.4 times more often (Alzheimer’s Association, 2007). Much of this cost stems from attempts to treat challenging aggressive behaviors with medication,(More)
Australian football requires frequent intermittent sprinting close to peak running speed. However, tests assessing the capability to maintain intermittent peak running speed are not reported in scientific literature. Therefore, our objective is to report the reliability and validity of a novel intermittent peak running speed test. The intermittent peak(More)
OBJECTIVES To develop a valid and reliable video-based decision-making test to examine and monitor the decision-making performance of Australian football umpires. DESIGN Validation assessments with test re-test reliability. METHODS A video-based decision-making test was developed from a pool of 156 video-based decision-making situations. Australian(More)
