Development of a Kinect Software Tool to Classify Movements during Active Video Gaming.

While it has been established that using full body motion to play active video games results in increased levels of energy expenditure, there is little information on the classification of human movement during active video game play in relationship to fundamental movement skills. The aim of this study was to validate software utilising Kinect sensor motion capture technology to recognise fundamental movement skills (FMS), during active video game play. Two human assessors rated jumping and side-stepping and these assessments were compared to the Kinect Action Recognition Tool (KART), to establish a level of agreement and determine the number of movements completed during five minutes of active video game play, for 43 children (m = 12 years 7 months ± 1 year 6 months).

Factors Influencing the Health Behaviour of Indigenous Australians: Perspectives from Support People.

Disparities between the health of Indigenous and non-Indigenous populations continue to be prevalent within Australia. Research suggests that Indigenous people participate in health risk behaviour more often than their non-Indigenous counterparts, and that such behaviour has a substantial impact on health outcomes. Although this would indicate that reducing health risk behaviour may have positive effects on health outcomes, the factors that influence Indigenous health behaviour are still poorly understood.

Factors Affecting Indigenous West Australians' Health Behavior: Indigenous Perspectives.

The factors driving the disparity in health outcomes between Indigenous and non-Indigenous Australians include socio-economic factors, racism, and history. The current study focused on exploring Indigenous participants' perspectives of the factors that affect the health behavior of their community members. Participatory action research methodology and a grounded theory approach were utilized.

The Dynamic Family Home: a qualitative exploration of physical environmental influences on children's sedentary behaviour and physical activity within the home space.

Background: Recent changes in home physical environments, such as decreasing outdoor space and increasing electronic media, may negatively affect health by facilitating sedentariness and reducing physical activity. As children spend much of their time at home they are particularly vulnerable. This study qualitatively explored family perceptions of physical environmental influences on sedentary behaviour and physical activity within the home space.

The effect of social support on the health of Indigenous Australians in a metropolitan community.

The factors driving the disparity in health outcomes between Indigenous and non-Indigenous Australians continue to be poorly understood. Despite this, studies confirm that social connections are a very important part of Indigenous life, and it is likely these connections play an important role in influencing health outcomes among this population. Examining the support provided by social connections in relation to health behaviour may assist our understanding of health outcomes among Indigenous Australians.

Does movement proficiency impact on exergaming performance?

There is growing interest in the use of consumer level exergames in movement skill acquisition. The purpose of this study was to investigate the relationship between movement proficiency and performance in virtual exergaming. Twenty seven children, aged 10-15years participated in an experiment completing the Movement Assessment Battery for Children 2 (MABC-2) and a series of XBOX360 Kinect Sports exergaming tasks.

New-Generation Active Videogaming Maintains Energy Expenditure in Children Across Repeated Bouts.

Objective: Active videogames (AVGs) remain popular among 10-15-year-old children. The Xbox 360 Kinect™ from Microsoft (Redmond, WA) represents a new generation of AVGs where body movements are used to control gameplay. The purpose of this study was to measure energy expenditure required to play repeated bouts of six Microsoft Xbox 360 Kinect games ("Motion Sports Adrenaline™," "Sonic Free Riders™," "Virtua Tennis 4™," "Kinect Sports™," "Kinect Adventures™," and "Just Dance 3™").

A place for play? The influence of the home physical environment on children's physical activity and sedentary behaviour.

The home environment is an important influence on the sedentary behaviour and physical activity of children, who have limited independent mobility and spend much of their time at home. This article reviews the current evidence regarding the influence of the home physical environment on the sedentary behaviour and physical activity of children aged 8-14 years. A literature search of peer reviewed articles published between 2005 and 2011 resulted in 38 observational studies (21 with activity outcomes, 23 with sedentary outcomes) and 11 experimental studies included in the review.

Optimising sprint interval exercise to maximise energy expenditure and enjoyment in overweight boys.

The aim of this study was to identify the sprint frequency that when supplemented to continuous exercise at the intensity that maximises fat oxidation (Fat(max)), optimises energy expenditure, acute postexercise energy intake and enjoyment. Eleven overweight boys completed 30 min of either continuous cycling at Fat(max) (MOD), or sprint interval exercise that consisted of continuous cycling at Fat(max) interspersed with 4-s maximal sprints every 2 min (SI(120)), every 1 min (SI(60)), or every 30 s (SI(30)). Energy expenditure was assessed during exercise, after which participants completed a modified Physical Activity Enjoyment Scale (PACES) followed by a buffet-type breakfast to measure acute postexercise energy intake.

Life after the game--injury profile of past elite Australian football players.

Objectives: To investigate the long-term health and well-being of past elite Australian Football League (AFL) players, with particular emphasis on the effect of playing injuries on current lifestyle.

Design: Cross sectional survey.

Methods: A health and well-being survey, completed by past AFL players (n=592) with mean (±SD) age of 55.

Effects of electrostimulation therapy on recovery from acute team-sport activity.

Purpose: To assess the efficacy of a 1-off electrostimulation treatment as a recovery modality from acute team-sport exercise, directly comparing the benefits to contrast water therapy.

Methods: Ten moderately trained male athletes completed a simulated team-game circuit (STGC). At the conclusion of exercise, participants then completed a 30-min recovery modality of either electrostimulation therapy (EST), contrast water therapy (CWT), or a passive resting control condition (CON).

The epidemiology of injury among surfers, kite surfers and personal watercraft riders: wind and waves.

The objective of this review was to summarize the epidemiological literature for surfboard riding (surfing), kite surfing and personal watercraft (PWC) riding injuries and describe the incidence and nature of these injuries, common risk factors, and strategies for prevention. The databases searched for relevant publications included Medline, ScienceDirect, ProQuest International, PubMed, Academic Search Premier as well as Google Scholar to identify additional, non-indexed studies. Overall, there was a lack of good quality descriptive studies for these three sports and many of the studies reviewed involved the use of administrative datasets or case-series designs.

Adding sprints to continuous exercise at the intensity that maximises fat oxidation: implications for acute energy balance and enjoyment.

The objective was to examine the effect of adding sprints to continuous exercise at the intensity that maximises fat oxidation (Fat(max)) on energy expenditure, substrate oxidation, enjoyment and post-exercise energy intake in boys. Nine overweight and nine normal weight boys (8-12 years) attended the laboratory on three mornings. First, body anthropometrics, peak aerobic capacity and Fat(max) were assessed.

Can we teach moderate intensity activity? Adult perception of moderate intensity walking.

Objectives: To investigate how people determine the intensity of their physical activity, respond to instruction, and their understanding of moderate intensity walking.

Design: Experimental.

Methods: Forty nine regular walkers had their walking speed, heart rate and rate of perceived exertion measured during their normal walking behaviour, when instructed to walk at a moderate intensity, and after provision of feedback on how to meet moderate intensity walking.

Does exercise duration affect Fatmax in overweight boys?

To compare the assessment of Fat(max) using a single graded exercise test with 3 min stages against 30 min prolonged exercise bouts in overweight boys. Ten overweight boys (8-12 years) attended the laboratory on seven separate occasions. On the first visit, body anthropometrics and peak aerobic capacity ([Formula: see text]O(2peak)) were assessed.

Substrate oxidation in overweight boys at rest, during exercise and acute post-exercise recovery.

Objective: To compare substrate oxidation between normal weight (n = 10) and overweight (n = 10) boys at rest, during exercise at 50% VO(2peak) and during the first 30 minutes of recovery post-exercise.

Study Design: Twenty boys (8-11 years) were tested over two separate occasions. At the first session, body composition was measured by Dual-Energy X-ray Absorptiometry and peak aerobic capacity (VO(2peak)) was assessed using an incremental treadmill protocol.
