- Description: Childhood sport participation is associated with physical, social, and mental health benefits, which are more likely to be realized if the sport environment is safe. However, our understanding of children’s experience of psychological, physical, and sexual violence in community sport in Australia is limited. The aims of this study were to provide preliminary evidence on the extent of experiences of violence during childhood participation in Australian community sport and to identify common perpetrators of and risk factors for violence. The Violence Towards Athletes Questionnaire (VTAQ) was administered online to a convenience sample of Australian adults (>18 years), retrospectively reporting experiences of violence during childhood community sport. Frequencies of experience of violence were calculated and Chi-square tests were conducted to determine differences between genders. In total, there were 886 respondents included in the analysis. Most survey respondents were women (63%) and about a third were men (35%). About 82% of respondents experienced violence in sport as a child. Psychological violence was most prevalent (76%), followed by physical (66%) and sexual (38%) violence. Peers perpetrated the highest rates of psychological violence (69%), and the rates of physical and psychological violence by coaches (both >50%) were also high. Age, sexual orientation, disability, and hours of weekly sport participation as a child were all associated with childhood experience of violence in sport. The rates of interpersonal violence against children in sport were high. This novel data on perpetrators of the violence and the risk factors for experiencing violence provides further context to inform safeguarding strategies in sport. A national prevalence study is recommended to advance our understanding of the childhood experiences of violence in Australian sport. © The Author(s) 2022.

- Description: OBJECTIVE - The purpose of this study was to assess the effectiveness of a low-resource-intensive lifestyle modification program incorporating resistance training and to compare a gymnasium-based with a home-based resistance training program on diabetes diagnosis sa us and risk. RESEARCH DESIGN AND METHODS - A quasi-experimental two-group study was undertaken with 122 participants with diabetes risk factors; 36.9% had impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) at baseline. The intervention included a 6-week group self-management education program, a gymnasium-based or home-based 12-week resistance training program, and a 34-week maintenance program. Fasting plasma glucose (FPG) and 2-h plasma glucose, blood lipids, blood pressure, body composition, physical activity, and diet were assessed at baseline and week 52. RESULTS - Mean 2-h plasma glucose and FPG fell by 0.34 mmol/l (95% CI -0.60 to -0.08) and 0.15 mmol/l (-0.23 to -0.07), respectively. The proportion of participants with IFG or IGT decreased from 36.9 to 23.0% (P = 0.006). Mean weight loss was 4.07 kg (-4.99 to -3.15). The only significant difference between resistance training groups was a greater reduction in systolic blood pressure for the gymnasium-based group (P = 0.008). CONCLUSIONS - This intervention significantly improved diabetes diagnostic status and reduced diabetes risk to a degree comparable to that of other low-resource-intensive lifestyle modification programs and more intensive interventions applied to individuals with IGT. The effects of home-based and gymnasium-based resistance training did not differ significantly.

- Description: This research was undertaken as part of the evaluation of the VicHealth Participation for Health (PfH) Scheme. VicHealth allocate A$ 3.3 million per year to support Victorian state sporting associations (SSAs) through the PfH Scheme to increase population physical activity levels and health via increasing membership of sporting clubs. SSAs were required to allocate a portion of these funds to participation based programs. While setting for participation was not directed, many (n = 27, 44.0%) of the SSAs conducted school-based sport programs. This research sought to explore the factors affecting the linking of school-based programs with sporting club membership. SSAs reported that 50.6% of the PfH Scheme programs (n = 43) were delivered in a school setting. Focus-group discussions found that, in general, the SSAs did not see the school-based programs being a vehicle for directly recruiting club members. Rather, the programs were used to increase the visibility of the sport, train teachers in the sport and to involve children in physical activity. Barriers to linking school-based program participation to club membership included conflict in program delivery time with club activities, and limited ability of club volunteers to assist with school-based programs. A case-study will be presented which involves the introduction of yachting into schools. In general, the SSAs believed school-based engagement was a poor investment. They also felt that agencies such as VicHealth should advocate for the provision of adequate sport infrastructure within schools rather than the schools relying upon the limited resources of the sporting sector to provide school sport services.

- Description: The task of dragging sheep into position for shearing has been reported by shearers as the most physically demanding and one of the highest injury risk aspects of shearing, particularly with regard to back injury. This study aimed to identify which of the currently used drag paths induced the lowest energy consumption and risk of injury. The drag path with the lowest work economy (oxygen cost per sheep dragged per minute) and highest injury risk is used by left-handed shearers who are shearing from a workstation which is designed for right-handed shearers. Importantly, there were no significant differences in the work economy of the two drag paths which were used most frequently and which involved the lowest injury risk. These data have been used in advocating the adoption of simple shearing shed design solutions to assist in the control of injury risk and energy expenditure in the wool industry.

- Description: Because operational tasks in the uniformed services (military, police, fire and emergency services) are physically demanding and incur the risk of injury, employment policy in these services is usually competency based and predicated on objective physical employment standards (PESs) based on physical employment tests (PETs). In this paper, a comprehensive framework for the design of PETs and PESs is presented. Three broad approaches to physical employment testing are described and compared: generic predictive testing; task-related predictive testing; task simulation testing. Techniques for the selection of a set of tests with good coverage of job requirements, including job task analysis, physical demands analysis and correlation analysis, are discussed. Regarding individual PETs, theoretical considerations including measurability, discriminating power, reliability and validity, and practical considerations, including development of protocols, resource requirements, administrative issues and safety, are considered. With regard to the setting of PESs, criterion referencing and norm referencing are discussed. Statement of Relevance: This paper presents an integrated and coherent framework for the development of PESs and hence provides a much needed theoretically based but practically oriented guide for organisations seeking to establish valid and defensible PESs. © 2010 Taylor & Francis.

- Description: Military operational tasks are physically demanding and incur the risk of injury. In order to address the issues and costs associated with the high injury rates and focus on ways to reduce the risk of injury to Australian Defence Force (ADF) personnel, the ADF Chiefs of Service Committee (COSC) has endorsed a number of injury prevention strategies aimed at examining, analysing and evaluating injury-related risks and hazards within the ADF. In line with those strategies, COSC has affirmed that ADF employment policy is to be competency based and agreed that physical employment standards should be developed for combat arms trades. The purpose of the Defence Physical Employment Standards Project (DPESP) is to develop these performance-based competency standards. The ADF has employed the services of the University of Ballarat (UB) to undertake the DPESP. This involves reviewing combat arms trade tasks (CATTs), establishing a set of criterion CATTs, developing a battery of simulation and predictive tests based on the criterion CATTs to be used to assess the physical competency of ADF combat personnel, and making recommendations for associated physical employment standards. In the initial phase, the study is focused on one Army corps - Infantry, and one Air Force mustering - Airfield Defence Guards (ADG)1. The aim of this work package was to identify a range of potential tests that may be used by the ADF to predict performance on trade tasks that involve a significant endurance component and potentially a significant strength-endurance component. The work package also aimed to identify a battery of kinanthropometric tests for use within the Defence Physical Employment Standards Project (DPESP). The method used was to review the relevant academic and Defence literature and to conduct a oneday workshop attended by subject matter experts from the UB team and the ADF. The workshop was conducted in a manner that enabled the participants to comment on the literature provided by way of a background briefing paper and to use their collective experience and expertise to identify a number of potential tests and measures in keeping with the overall aim of the work package. It was assumed that the criterion endurance trade task would be the 50 km pack march. The literature review identified a range of approaches to the selection or development of a test to predicted performance on the 50 km pack march. These approaches include the prediction of endurance capacity from: • a direct measure of a related trade task (e.g. a shorter pack march) (Approach A);

- Description: The Australian Defence Force (ADF) has resolved to establish a series of physical employment standards for Infantry soldiers and Airfield Defence Guards. A key stage in establishing these standards is to analyse the physical requirements of the two jobs. The purpose of this study was to analyse the physical requirements of the key physical tasks required within the two jobs. The jobs were divided into over 100 component tasks. Some tasks were common to the two jobs while others were specific to the respective jobs. ADF subject matter experts identified 36 tasks that were considered to be the most physically demanding. These tasks were observed to determine the movement patterns (actions) and muscle groups involved, the duration, velocity and estimated of exercise intensity. An estimate was also made of the involvement of each of seven activity types (endurance, strength-endurance etc) in each task and the exercise volume contained within each task. The tasks were ranked based upon the volume of work involved within each classification of activity type and movement action. Based upon these analyses, a series of tasks were chosen as those which best reflected the range of physical requirements of an Infantry soldier and an Airfield Defence Guard. These tasks were: marching while carrying support weapons, carrying ammunition boxes, assaulting, wall climbing, sandbagging, jumping from a height, pursuiting, rope climbing, patrolling in an urban environment, population protection, patrolling in marching order, building forced entry and stair climbing, casualty evacuation, loading stores and digging.

- Description: PURPOSE: The purpose of this study was to compare the effectiveness of bell-and-pad alarm therapy to body-worn alarm therapy for the management of monosymptomatic enuresis in children 6 to 16 years of age. DESIGN: A prospective, randomized, adaptive clinical control trial. SUBJECTS AND SETTING: The sample comprised 86 children who attended a continence clinic for treatment of monosymptomatic enuresis and met the criteria for enuresis alarm therapy as per International Children's Continence Society (ICCS) guidelines. Subjects were randomly allocated to an experimental group (body-worn alarm, n = 41) or a control group (bell-and-pad alarm, n = 45). The study setting was a single-site specialist continence service in regional Victoria, Australia. Treatment was administered in the child's home. METHODS: Alarm therapy was administered by the child and/or parent for an initial period of 8 weeks at which time the child underwent a review with the continence nurse specialist. If the child had achieved 14 consecutive dry nights, the therapy was deemed successful and ceased. Children who had not become dry continued therapy for a further 8 weeks up to a maximum of 16 weeks, with a final review was instituted. Each child kept a diary for the duration of alarm therapy to report on frequency of wet/dry nights, times of alarm, response to alarm, and response to sensation to void (without alarm). The 2 types of alarm devices were compared with respect to categorical variables using dichotomous cross-tabulations and χ tests of independence based on the most positive outcome versus the other outcomes. RESULTS: Dryness in accordance with the criteria outlined by the ICCS guidelines was achieved in 18 children (43.9%) in the body-worn alarm group versus 29 children (64.4%) in the routine (bell-and-pad) group (P = .056). The bell-and-pad alarm performed better on 7 out of the 9 indicators, including the primary outcome measure of the child attained dryness for 14 nights or more, nightly alarm use, alarm woke child, alarm woke parent (P = .022), false (positive) alarms (P = .039), child turned alarm off and went back to sleep (P = .003), and child was compliant with alarm use. The body-worn device produced higher proportions of the most positive outcomes for 2 of the 9 indicators: relapse (P = .076) and false (negative) nonalarms (P = .066). CONCLUSIONS: Study findings suggests that the bell-and-pad alarm is preferable to the body-worn alarm. Additional research is recommended using other body-worn alarm devices across a larger population in order to establish the more definitive findings needed for clinical decision-making.

- Description: Few studies have considered surface temperatures on the most recent synthetic turf products, and no empirical evidence is available on the more technologically advanced cool climate synthetic products which claim to reduce surface temperature. This article compared surface temperatures of typical third-generation synthetic turf with a cool climate product and also compared the synthetic turf products to natural grass to determine whether synthetic turf reacts differently to environmental factors and hence may increase heat-related health risks for participants. Surface temperatures were significantly associated with ambient temperature (F3,376 = 116.02, p < 0.001), relative humidity (F1,376 = 10.15, p = 0.028), and wind (F1,376 = 1.45, p = 0.004) having smaller effects. After adjustment for covariates, mean surface temperatures were significantly lower (40.79 °C) on a cool climate field compared to a typical third-generation field (44.91 °C), although both synthetic fields were considerably warmer than natural grass at the same venue (by 12.46 °C at the metropolitan venue and 22.15 °C at the regional venue). These findings provide initial insight into the potential value of cool climate products and will aid both design and development of synthetic turf products for the future. © IMechE 2014.

- Description: Surface temperatures of synthetic turf have become a factor of growing interest and concern, particularly in warmer regions like Australia. However, it is unclear which components of the synthetic turf system contribute to surface temperature. The aim of this paper was to compare the surface temperature of 34 different synthetic turf products that were exposed to the same environmental conditions to ascertain which components of the synthetic turf system and which environmental factors contributed to increased surface temperature. A total of 6,120 observations were taken on the 34 products over the summer months, giving 30 observations for each of the variables on each product. An analysis of covariance (ANCOVA) indicated that the type of infill and shockpad had small-medium, but significant, effects on surface temperature (p<0.001 and p=0.003, respectively), and the interaction between shockpad and tuft gauge was also significant (p=0.047). Level of solar radiation, ambient temperature and relative humidity (p<0.001 in all instances) were the only environmental variables that significantly influenced surface temperature. These findings confirm that both the composition of the synthetic turf system and environmental factors contribute to synthetic turf surface temperature, thus providing important information for synthetic turf manufacturers developing new cool climate products, or for local government authorities selecting products and/or informing safe play for end-users.

Physical Education and Sports Sciences students (n = 263) completed the "Can You Swim?" self-report survey and practical skills assessment, unaware that the practical tests replicated survey items. Relationships for comparisons between practical tests and their matched survey item were weak, indicating participants had inaccurate perceptions of their own swimming skills. Typically, they underestimated their competence in terms of distance and fundamental aquatic skills. Understanding of what constitutes different levels of swimming ability was poor; for example, most participants identified as average or good to excellent swimmers, but more than half of self-identified average swimmers and 20% of good to excellent swimmers estimated they could complete < 100 m of continuous swimming. The implications of study findings for drowning prevention and the need for further research are discussed. © 2012 Human Kinetics, Inc.

- Description: Wildfire fighters are known to report to work in a hypohydrated state, which may compromise their work performance and health. Purpose: To evaluate whether ingesting a bolus of fluid before the shift had any effect on firefighters' fluid consumption, core temperature, or the time they spent in high heart rate and work activity zones when fighting emergency wildfires. Methods: Thirty-two firefighters were divided into non-bolus (AD) and pre-shift drinking bolus (PS, 500 ml water) groups. Results: Firefighters began work hypohydrated as indicated by urine colour, specific gravity and plasma osmolality (Posm) results. Post-shift, firefighters were classified as euhydrated according to Posm and hypohydrated by urinary markers. No significant differences existed between the drinking groups in pre- or post-shift hydration status, total fluid intake, activity, heart rate or core temperature. Conclusion: Consuming a bolus of fluid, pre-shift provided no benefit over non-consumption as both groups had consumed equivalent ad libitum volumes of fluid, 2.5 h into the shift. No benefits of bolus consumption were observed in firefighter activity, heart rate response or core temperature response across the shift in the mild weather conditions experienced. Ad libitum drinking was adequate to facilitate rehydration in firefighters upon completion of their emergency firefighting work shift. © 2011 Elsevier Ltd and The Ergonomics Society.
