- Description: Background: There are specific guidelines regarding the level of physical activity (PA) required to provide health benefits. However, the research underpinning these PA guidelines does not address the element of social health. Furthermore, there is insufficient evidence about the levels or types of PA associated specifically with psychological health. This paper first presents the results of a systematic review of the psychological and social health benefits of participation in sport by children and adolescents. Secondly, the information arising from the systematic review has been used to develop a conceptual model.Methods: A systematic review of 14 electronic databases was conducted in June 2012, and studies published since 1990 were considered for inclusion. Studies that addressed mental and/or social health benefits from participation in sport were included.Results: A total of 3668 publications were initially identified, of which 30 met the selection criteria. There were many different psychological and social health benefits reported, with the most commonly being improved self-esteem, social interaction followed by fewer depressive symptoms. Sport may be associated with improved psychosocial health above and beyond improvements attributable to participation in PA. Specifically, team sport seems to be associated with improved health outcomes compared to individual activities, due to the social nature of the participation. A conceptual model, Health through Sport, is proposed. The model depicts the relationship between psychological, psychosocial and social health domains, and their positive associations with sport participation, as reported in the literature. However, it is acknowledged that the capacity to determine the existence and direction of causal links between participation and health is limited by the fact that the majority of studies identified (n=21) were cross-sectional.Conclusion: It is recommended that community sport participation is advocated as a form of leisure time PA for children and adolescents, in an effort to not only improve physical health in relation to such matters as the obesity crisis, but also to enhance psychological and social health outcomes. It is also recommended that the causal link between participation in sport and psychosocial health be further investigated and the conceptual model of Health through Sport tested. © 2013 Eime et al.; licensee BioMed Central Ltd.

- Description: Background: Much research has been conducted into the determinants of physical activity (PA) participation among adolescent girls. However, the more specific question of what are the determinants of particular forms of PA participation, such as the link between participation through a sports club, has not been investigated. Accordingly, the aim of this study was to investigate the relationships between participation in a sports club and socio-economic status (SES), access to facilities, and family and peer support, for female adolescents.Methods: A survey of 732 female adolescent school students (521 metropolitan, 211 non-metropolitan; 489 Year 7, 243 Year 11) was conducted. The survey included demographic information (living arrangements, ethnicity indicators, and indicators of SES such as parental education and employment status and locality); access to facilities; and family and peer support (travel, encouragement, watching, praise, joint participation). For each characteristic, sports club participants and non-participants were compared using chi-square tests. Multiple mediation analyses were used to investigate the role of access, family and peer support in the link between SES and sport participation.Results: There were significant associations (p<0.05) between sports club participation and: all demographic characteristics; all measures of family and peer support; and access to sport-related facilities. Highest levels of participation were associated with monolingual Australian-born families, with two parents, at least one of whom was well-educated, with both parents employed, and high levels of parental assistance, engagement and support. Participation in club sport among both younger and older adolescent girls was significantly positively associated with the SES of both their neighbourhoods and their households, particularly in metropolitan areas. These associations were most strongly mediated by family support and by access to facilities.Conclusions: To facilitate and promote greater participation in club sport among adolescent girls from low SES neighbourhoods and households, strategies should target modifiable determinants such as facility access and parental support. This will involve improving access to sports facilities and promoting, encouraging and assisting parents to provide support for their daughters' participation in sport clubs. © 2013 Eime et al.; licensee BioMed Central Ltd.

- Description: The engagement of adolescent girls in physical activity (PA) is a persistent challenge. School-based PA programs have often met with little success because of the lack of linkages between school and community PA settings. The Triple G program aimed to improve PA levels of secondary school girls (12-15 years) in regional Victoria, Australia. The program included a school-based physical education (PE) component that uniquely incorporated student-centered teaching and behavioral skill development. The school component was conceptually and practically linked to a community component that emphasized appropriate structures for participation. The program was informed by ethnographic fieldwork to understand the contextual factors that affect girls' participation in PA. A collaborative intervention design was undertaken to align with PE curriculum and coaching and instructional approaches in community PA settings. The theoretical framework for the intervention was the socioecological model that was underpinned by both individual-level (social cognitive theory) and organizational-level (building organizational/community capacity) strategies. The program model provides an innovative conceptual framework for linking school PE with community sport and recreation and may benefit other PA programs seeking to engage adolescent girls. The objective of this article is to describe program development and the unique theoretical framework and curriculum approaches.

- Description: Introduction: The Sport and Recreation Spatial project is a collaborative partnership between national and state sport, recreation, health, government and university organisations. It involves the development of a geographical information system (GIS) for presenting spatial data relevant to all levels of the sport and recreation sector. Methods: The project was established to provide the sport and recreation sector with increased capacity for research, strategic planning, and development of participation programs and facilities. The integration of multiple large datasets provides a strong evidence base for the sport and recreation sector. The key research areas are: participation levels and trends; influences on participation; value of sport – the health benefits of participation; and places to play – the nexus between facilities and participation. The integrated, dynamic database system incorporates data about sport and recreation participation and facilities in conjunction with population demographic data. The initial tranche of participation data includes around 200,000 data records from the national Exercise, Recreation and Sport Survey (2001–2010) and over 1.8 million player, coach and umpire records from eight Victorian State Sporting Associations (2008–2012). Results: A live presentation of the GIS interface will demonstrate the wide range of interactive user-specified options and queries and the resulting “on-the-fly” generation of maps and associated tables illustrating participation trends across time and geographical locations. Discussion: This project is providing increased capacity for strategic planning and development of participation programs and facilities. Whilst we may know broad trends in participation across time, this project allows dynamic investigations across multiple datasets, of questions relating to specific geographical locations, which may pertain to population demographics, participation (player, coach and umpire) trends, and/or infrastructure development. National implementation of this system will provide social, health and economic benefits.

- Description: The purpose of this study was to examine 1) wildfire fighters' ability to consume the prescribed fluid volume (1200 mL h-1), 2) the effect of fluid intake on plasma sodium and hydration, and 3) the effect of fluid intake on firefighters' heart rate, core temperature and activity during emergency suppression shifts. Methods: Thirty-four firefighters were divided into ad libitum (AD, n = 17) and prescribed (PR, n = 17) drinking groups. Results: PR drinkers did not meet the prescribed fluid target, yet consumed over double the volume of AD drinkers. No differences between groups in plasma sodium or hydration were noted. PR drinking resulted in lower core temperature between 2 and 6 h. This did not coincide with reduced cardiovascular strain, greater work activity or larger distances covered when compared to AD drinkers. Conclusion: Extra fluid consumption (above AD) did not improve firefighter activity or physiological function (though PR firefighters core temperature was lower earlier in their shift). Firefighter can self-regulate their fluid consumption behavior and work rate to leave the fireground euhydrated. © 2012 Elsevier Ltd and The Ergonomics Society.

- Description: This study examined the relationship between educational year level, regional differences in adolescent girls' body image perceptions, body mass index (BMI), physical activity (PA) level, self-reported health, and dietary behaviour. Also, the role of PA behavioural regulation on body image was examined. The sample (N=732; Year 7 aged 12.23 years and Year 11 aged 16.18 years) included girls in Year 7 (n=489) and in Year 11 (n=243), recruited from 17 metropolitan and 14 rural schools in Victoria, Australia. Girls completed a self-report questionnaire. Novel outcomes from this study revealed year level and region differences in girls' body image perceptions, BMI, and health behaviours. Body dissatisfaction was associated with poorer perceived health, and health behaviours, such as low PA levels and dieting and external PA motivational orientation. Interventions are needed to promote positive body image and intrinsic motivation for PA to increase PA levels among adolescent girls living in metropolitan and rural regions of Australia.

- Description: Purpose: Participation in physical activity (PA) is reported to decline in adolescence, particularly for girls. However, we do not know if this decline in PA is consistent across modes and settings or whether there are transfers of participation between modes and settings. Nor do we understand the changes in specific types of PA or the interaction between types of participation and different modes/settings. This study investigated contexts of PA participation for female adolescents at two life transition points. Method: A survey of 489 Year 7 and 243 Year 11 adolescent girls was conducted, incorporating a measure of overall PA level and participation rates in seven modes/settings and in specific types of sport and PA. Results: Less than half of the respondents met or exceeded the recommended level of moderate or vigorous PA-60 min or more-on the previous day, and there was no statistically significant difference in the proportions in Years 7 and 11 (39.5% vs. 45.9%; p > .05). However, older adolescents shifted their participation away from organized, competitive modes and settings toward nonorganized and noncompetitive modes and settings and individual types of PA. Conclusions: An understanding of the changes in PA modes and settings identified here can inform the planning of policies and implementation of programs for the promotion of PA by adolescent girls.

- Description: Background: Leukocyte telomere length is a marker of biological ageing and its shortening is associated with cardiovascular disease. Engagement in regular moderate-intensity physical activity is a recognised method of cardiovascular disease prevention. However, it is not clear whether repeated exposure to ultra-strenuous physical exercise is beneficial long-term and whether it may attenuate biological ageing. Methods: We compared leukocyte telomere length in context of inflammation and endothelial dysfunction between 67 male ultra-marathon runners and 67 age-, sex- and BMI-matched apparently healthy controls. Genomic DNA was extracted from peripheral blood and leukocyte telomere length was measured by quantitative polymerase chain reaction assays. Adhesion molecules (sICAM-1, sE-selectin) and inflammatory markers (IL-6, C-reactive protein) concentrations were measured in 67 ultra-marathon runners by quantitative sandwich enzyme immunoassay technique, high-sensitive immunoassay and ultra-sensitive double antibody sandwich ELISA, respectively. Results: Adjusted (for age, BMI, blood pressure and lipids) leukocyte telomere length was approximately 13.8% greater in the ultra-marathon runners than in the controls (P<0.001). This translates into approximately 32.9 years difference in age-related telomere length attrition. There was a strong negative linear correlation between sICAM-1 and leukocyte telomere length in the ultra-marathon runners (r=-0.33; P=0.007) and this association retained its statistical significance after adjustment for age, BMI, blood pressure and lipids in multiple regression (P=0.026). Conclusion: Prolonged, intense physical exercise may attenuate cellular ageing possibly through a protective effect on endothelial function.

- Description: Purpose: Previous US research has consistently revealed females reporting lower pay expectations and entitlements compared to their male counterparts. The purpose of this paper is to investigate whether these gender differences still exist, specifically in British and Australian business students, or whether there has been a generation shift in attitudes. Design/methodology/approach: Quantitative data were analysed from 481 (252 females and 229 males) university students, on their responses to what they "expected" to earn five years after graduation and what they thought they "deserved" to earn. Students from two British universities (n=285) and two Australian universities (n=196) participated. Findings: Results revealed that the presence of very high values (outliers) reported by a small proportion of male respondents led to apparent gender differences in perceived entitlement (deserved salary). However, appropriately modified analyses showed no significant gender differences in expected salary, deserved salary or salary difference. Differences were observed between countries; in the UK expectations and views on deserved salary were higher than those expressed in Australia. In addition, in both countries' students from higher ranking universities expected higher salaries and believed they deserved a higher salary. Research limitations/implications: The sample is restricted to University business students and may not generalise to other groups. Practical implications: Implications of these findings reflect on gender pay inequities, along with methodological issues for future research. Originality/value: This paper challenges the long-held view that, in general, males have more positive expectations of their future salaries than females. While this has been reported in the past, the paper illustrates that in a contemporary sample across two countries, the great majority of male and female students had very similar expectations for their future salary. The paper proposes some explanations that may account for this phenomenon. The only clear gender difference observed was the presence of a small proportion of males with extremely high salary expectations; the paper highlights the necessity for appropriate statistical analysis of such highly skewed data. © Emerald Group Publishing Limited.

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: The aim of this paper is to evaluate changes in organizational capacity and sport-related health promotion policies and practices among State Sporting Organizations (SSOs) who participated in the Partnership for Health (PfH) scheme. The PfH scheme aimed to support the development and implementation of sport-related health promotion policies and practices at SSO-organized events and within their affiliated sports clubs. SSO representatives completed the Health Promotion and Sport Assessment Tool (HP-SAT) twice. Respondents reported capacities, policies, and practices prior to the scheme (retrospective pre-scheme survey), and current capacities, policies, and practices (post-scheme survey). The mean scores (on standardized scales: 0–100) for all components of organizational capacity for health promotion increased significantly between pre-scheme and post-scheme. Similarly, compliance scores for most sport-related health promotion policies and practices for SSO-organized events and support to clubs increased significantly. However, post-scheme strategic planning for health promotion remained low and scores for policies and practices for clubs were generally lower than for SSO-organized events. No significant differences were found between small and large SSOs regarding capacities, policies, or practices. The PfH scheme had a positive impact on most aspects of health promotion capacities, policies, and practices. However, there was room for further improvement in strategic planning and in support for affiliated clubs. Low levels of strategic planning should be addressed by SSOs, and a more extensive engagement between SSOs and affiliated clubs is required to operationalize health promotion strategies at club level.

- Description: The aim of this research was to provide a comparative analysis of the influence of behavioural alternatives, autonomy, competence and relatedness on participation in sport and physical activity for female adolescents within metropolitan and rural settings. Eighteen focus groups were conducted with a cross section of schools within metropolitan Melbourne and rural Victoria, Australia, involving 12-13-year olds and 15-16-year olds, using a semi-structured format. Content and thematic analyses were conducted on the data. Findings supported the sport commitment model by demonstrating that, in both rural and metropolitan settings, participation was influenced by the strength of commitment to a range of behavioural alternatives. Our findings also extended self-determination theory by suggesting that autonomy, competence, and relatedness were interrelated and their strength and influence on participation varied between settings. This study also has practical implications, including the promotion of more inclusive and supportive sports environments for female adolescents and promoting sport and physical activities as activity that promotes wellness, complements academic endeavours and reduces the stress of academic study. © 2011 Taylor & Francis.

- Description: Objective: To determine the current level of knowledge of first aid for a burn injury and sources of this knowledge among the general population of New South Wales. Design, setting and participants: People aged 16 years or older were interviewed as part of the 2007 NSW Population Health Survey, a continuous telephone survey of NSW residents. Main outcome measure: Weighted proportion of the population with optimal first aid knowledge for burns. Results: In total, 7320 respondents were asked questions related to burn injuries and first aid. Of the surveyed population, 82% reported that they would cool a burn with water, and 9% reported that they would cool the burn for the recommended 20 minutes. Few respondents reported that they would remove the patient’s clothing and keep the injured person warm. The most common sources of first aid information were a first aid book (42%) and the internet (33%). Speaking a language other than English at home, and being over 65 years of age were associated with a lack of first aid knowledge. Conclusions: A minority of people living in NSW know the optimal time for cooling a burn injury and other appropriate first aid steps for burns. This study demonstrates a gap in the public’s knowledge, especially among non-English speaking people and older people, and highlights the need for a clear, consistent first aid message.

- Description: Objective: Conceptual models and predictors of choking under pressure (i.e., choking) have been proposed, but the role of fear of negative evaluation remains largely unknown. The purpose of the current study was to determine the degree to which fear of negative evaluation (FNE) may predispose athletes to choking. Design and method: 138 Experienced basketball players participated in a pre-selection stage, which involved completing a set of questionnaires that included the Brief Fear of Negative Evaluation-II (BFNE-II) questionnaire. Based on the scores from the BFNE-II, 34 athletes, categorized as either low- or high-FNE, were selected to perform basketball shots from five different areas of the court under low- and high-pressure phases. Shooting performance was evaluated based on the total number of successful shots out of 50 attempts. Results: Results indicated that the high-FNE athletes displayed a significant increase in anxiety and a significant decrease in performance from low- to high-pressure phases. The low-FNE group exhibited only minimal changes in anxiety throughout the study and was able to maintain performance under pressure. Further mediation analysis investigating significant difference in performance between FNE groups within the high-pressure phase indicated that that cognitive anxiety was a partial mediator between FNE group and performance, but somatic anxiety was not. Conclusions: Findings extend the existing choking literature by providing empirical support for the role of FNE in the context of the self-presentation model of choking. © 2011 Elsevier Ltd.

- 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.

- Description: Regulations to restrict the temperature of domestic hot tap water were introduced in NSW in 1999. This study investigates the impact of the regulations on the knowledge, attitude and practice of workforce professionals responsible for their uptake and enforcement. Telephone surveys were conducted with a random sample of 110 plumbers and 30 regulating authorities. Surveys were recorded, transcribed and coded. Written questionnaires were completed by 151 plumbing students. The regulations are well known and supported by the majority of plumbers, students and regulators; however 75% of plumbers reported customer dissatisfaction with them. Only a minority of plumbers (11%), students (7%) and regulators (27%) correctly appreciated the impact of a decrease in water temperature in reducing burns. This study identifies the need to improve plumbers and students' understanding of the safety issues underlying the regulations in order to promote more effective advocacy for homes not currently covered by the regulations, and to provide more public education to increase acceptance of them. As only houses built or substantially renovated after June 1999 are likely to have been impacted by the current regulations, there is a need to increase the scope of the regulations to include not only new installations, but also the replacement of existing heated water units if the goal of universal protection is to be achieved. © 2010 Elsevier Ltd and ISBI.

Experienced field hockey players (N = 45) were randomly assigned to one of five groups (i.e., performance-contingent monetary incentive, video camera placebo, video camera self-presentation, audience, or combined pressure), before taking penalty strokes in low- and high-pressure phases. Results indicated that groups exposed to self-presentation manipulations experienced choking, whereas those receiving motivational pressure treatments decreased anxiety and increased performance under pressure. Furthermore, cognitive state anxiety mediated the relationship between the self-presentation group and performance. These findings provide quantitative support for the proposed self-presentation model of choking, while also holding implications for anxiety manipulations in future sport psychology research. © 2011 Human Kinetics, Inc.

- 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.
