The Impact of COVID-19 Restrictions on Perceived Health and Well-Being of Active Australian Older Adults.

The aim of this study was to determine the impact of COVID-19 restrictions on older adults' perceived health and well-being according to different types of participation in sport and physical activity by gender and region. A survey was implemented during the first COVID-19 lockdown in Australia (June 2020) and information collected on demographics, sport and physical activity patterns pre-COVID-19, and health and well-being outcomes during lockdown and compared to 1 year earlier. During COVID-19 lockdown, older adults who participated in both club sport and informal activities had significantly better general health, physical health, and resilience than those who participated solely in a single setting. Those participating in both team and individual activities reported better general well-being. Older adults who were active in a range of settings and modes had improved health and well-being. Social support is especially important for older adults to become and remain active.

The impact of COVID-19 restrictions on Australians' frequency and duration of participation in different types of sport and physical activity.

BACKGROUND: Sports management and public health physical activity stakeholders need to understand changing patterns of participation to inform the development of sport and physical activity opportunities and strategies. This study investigated changes in the frequency and duration of participation in sport and physical activity in Australia from pre-COVID-19 to during-COVID-19, broken down by the specific type of activity and by gender, age and region. METHODS: During the first pandemic restrictions and lockdowns in Australia in May-June 2020, 6140 survey respondents provided information about the types, frequency and duration of the sport and physical activity they participated in prior to and during COVID-19 restrictions. Differences between mean values were analyzed. RESULTS: The greatest decline in participation during COVID-19 was in team sports, and the decline was greater for men than for women. CONCLUSION: How will sport respond to getting these men back in the game, and women back from home-based yoga and Pilates?

Sport4Me: A people focused approach to engaging Australians in sport.

The traditional model of community club-based sport is fine for those, particularly children and youth, who enjoy the competitive focus and have the skills and commitment to play. But societal preferences during leisure time have changed dramatically over recent decades. However, sport organisations have made limited progress in response to these changes in providing ways in which children and youth can participate outside the traditional competitive structures and environments. In this paper the context of community club-based structures is reviewed leading into an assessment of the associated impact of these structures on sport participation. Children and youth's current motivations to play sport including what makes sport fun to play, are considered. It is then demonstrated that the associations between motivations to play sport and the factors that contribute to fun and enjoyment, are often misaligned for many individuals, with a primary focus on competition-based structures to deliver community club sport. In the final part of the paper a model for community sport organisations where people are put first is proposed - Sport4Me. Sport4Me is about flexible, inclusive, equitable sporting opportunities that focus on friends, fun, physical literacy and play. The model would complement the traditional competitive club-based model and afford participants more choice whilst fostering an environment that promotes lifelong involvement in sport. This model will require structural and cultural changes to the sporting environment and include coaching practices. Sport4Me is an evidence-based model, but it is not radical in its conceptualisation but rather, builds on previously proposed approaches, considers the needs and wants of potential sport participants and widens the scope of sport delivery.

Marketing Up the Wrong Tree? Organisational Perspectives on Attracting and/or Retaining Older Adults in Sport.

Community sport is seen as a suitable setting for physical activity for different population groups. Older adults (aged 50+ years) are a rapidly growing population group. Physical activity is critical for healthy ageing, however sport participation rates for older adults are very low. The aim of this study was to investigate how sporting organisations perceive sport for older adults. This cross-sectional study surveyed 171 representatives from Australian National and State Sporting Organisations. Descriptive statistics were used to summarise the results and the three sporting organisation categories' (high, medium, and low participation) responses were compared using non-parametric statistics. Contextualised in the perspective of organisational change, a framework for marketing to the ageing consumer was used to interpret the results. Older adults are not a high priority group for most sporting organisations, however the benefits of engaging older adults were recognised, particularly in context of increasing participation numbers. A lack of age-appropriate programmes was perceived to be a major barrier of engaging older adults. This lack of programmes stems from older adults being deemed as a less attractive segment than other age groups for sporting organisations. Modifications that sports felt they could make to attract and/or retain older adults included specific marketing and age appropriate opportunities. There was widespread consensus across sporting organisations, suggesting that perceptions of older adult sport participation were comparable across the sector, such as increasing participation numbers and engaging their older fan base. In the context of attracting, and retaining, older adults in sport clubs, it was concluded that most sporting organisations are not (yet) ready to build "age friendly" sporting environments. There is very limited literature on the organisational perspective of older adults and sport, meaning this study is unique in the field. Although sport policy encourages organisations to grow their participation, most organisations do not actively and strategically engage older adults. This research provides an understanding of why this untapped market is not a priority target and provides comprehensive insights for policy makers to better engage with this population group.

Artificial Intelligence and Machine Learning in Sport Research: An Introduction for Non-data Scientists.

In the last two decades, artificial intelligence (AI) has transformed the way in which we consume and analyse sports. The role of AI in improving decision-making and forecasting in sports, amongst many other advantages, is rapidly expanding and gaining more attention in both the academic sector and the industry. Nonetheless, for many sports audiences, professionals and policy makers, who are not particularly au courant or experts in AI, the connexion between artificial intelligence and sports remains fuzzy. Likewise, for many, the motivations for adopting a machine learning (ML) paradigm in sports analytics are still either faint or unclear. In this perspective paper, we present a high-level, non-technical, overview of the machine learning paradigm that motivates its potential for enhancing sports (performance and business) analytics. We provide a summary of some relevant research literature on the areas in which artificial intelligence and machine learning have been applied to the sports industry and in sport research. Finally, we present some hypothetical scenarios of how AI and ML could shape the future of sports.

Five-Year Changes in Community-Level Sport Participation, and the Role of Gender Strategies.

Background: The rate of participation in community-based sport by boys and men has been double that of girls and women. Contributing to this is the fact that some sports have been traditionally male-only or at least very male-dominated. Aim: The aim of this study was to investigate changes in participation in sport by sex and age across 10 major sports in Australia over a 4-year period. In conjunction with the analysis of participation trends, the gender strategies that were developed and implemented during this time are reviewed. Methods: This study encompassed all sport participants registered with one of 10 State Sporting Associations in Victoria, Australia in 2015 and in 2019. Participation rates by region, age and sex were calculated. State sport and health policies relating to female participation in sport were reviewed. Results: There were 749,037 registrations in 2015 and 868,266 in 2019. A comparison between 2015 and 2019 shows increases in participation for women and girls across all age groups (4-84 years), and highest increases for those aged 4 (6.6%) and 5-9 (4.7%). For boys there was a considerable decrease in participation for those aged 5-9 years (-3.8%). Discussion: This study provides evidence that whilst participation in sport is still dominated by males, the gap might be gradually closing and this is in line with recent strategies and investments into sport and wider cultural developments in society. The implications of these findings are discussed.

The Physical Activity and Sport Participation Framework-A Policy Model Toward Being Physically Active Across the Lifespan.

The changing social and policy context in which sport is produced, delivered, and consumed is considered as a foundation for proposing a new integrated framework that incorporates participation in sport with participation in leisure-time physical activity (PA) more broadly. In order to position sport in the broader context of leisure-time PA, the concept of physical literacy is reviewed and integrated into the theoretical foundations of a new lifespan framework. It is argued that historically, sport policy largely focused on competitive club-based sport and elite performance and that in line with this, talent development pathway models were developed and implemented. However, with increasing physical inactivity globally, these models do not apply to the general population. This is why we propose a population-based "whole of sport ecosystem" lifespan model-the Physical Activity and Sport Participation (PASP) framework. We conclude that this framework may serve as a holistic policy and implementation guide for all in the sport ecosystem. This includes governmental PA and sport policy makers, sport governing bodies and clubs, and the ever-increasing range of private PA and sport providers and also health agencies. In recognition of the changing patterns of participation in PA and sport across the lifespan, the PASP framework can contribute to coordinated and integrated PA and sport policy development, which, in turn, can lead to strategies that tackle the global physical inactivity crisis.

Longitudinal Trends in Sport Participation and Retention of Women and Girls.

Measurement and analysis of sport participation data is vital to understand trends, and therefore to make informed decisions relating to sport policy and strategies to get more people active through sport. This study identified patterns of club sport participation, retention and drop-out of women and girls over a 7 year period in a popular team sport in Australia. The study included registered women and girls of all ages (4-96 years at baseline) in an almost exclusively female sport, with a particular focus on the ages 4-14 years where most participation occurs. All commencing participants in the base year (2010) were tracked over the 7 year period. Participants were classified in two ways: the total number of years they played and their overall pattern of participation. Differences between age groups were analyzed using Kruskall Wallis and Mann Whitney tests. Registration records of 29,225 participants were analyzed in the study. Overall, there were considerable differences in the years participating in the sport. Almost one third (30%) of commencing 4-9 year olds played continuously for the 7 years. This proportion diminished through ages at commencement from 10 to 19, reaching a low point of 4% for ages 15-19, then rebounded slightly, reaching 7% for ages 30+. The proportion who dropped out during the 7 year period and did not return varied with age in the converse manner, as did the proportion of single-year players. The optimal age of entry to sport for retention in participation was 6-9 years. Consideration needs to be given to the age appropriateness of sports programs for very young participants. Strategies specifically relating to retention of girls and young women during adolescence should be developed.

Implementation of a modified sport programme to increase participation: Key stakeholder perspectives.

Modified sports, whereby equipment and rules are manipulated to facilitate skill performance, have been shown to promote skill learning and potentially increase participation. However, it is currently unexplored how key stakeholders - coaches and key figures working in National associations - who are critical stakeholders in implementing and delivering sport programmes, perceive modified sport. This study explored how tennis coaches and key figures working within tennis National associations perceived the impact of implementing a modified tennis campaign on participation and skill development in children and adults. Key figures and coaches around the world completed an online questionnaire. Both groups considered that modified tennis was positively associated with increasing and sustaining participation, skill learning, talent development and people's attitude towards tennis. Furthermore, participants thought that a rule change (i.e., use of a low-compression ball in children competitions) and the campaign's core messages (i.e., "serve, rally, score" and "easy, fun, and healthy") have been critical for the success of the campaign. These results support previous research on the positive impact of modified tennis on skill development and provide a further impetus on implementing modified sports to increase participation. Other sports can adopt similar strategies to improve their modified programmes.

Sport for Adults Aged 50+ Years: Participation Benefits and Barriers.

Despite the health benefits of sport, the proportion of people participating in sport decreases with age. This qualitative study explored the benefits and barriers regarding older adult community sport participation, from the perspective of national sporting organizations, in addition to older adult sport club and nonsport club members, across eight focus group interviews (n = 49). Seven benefits were discussed, primarily social and physical health and intergenerational opportunities. Ten barriers were also discussed, including physical health, time constraints, and lack of appropriate playing opportunities. Ensuring access to activities that can benefit social health is of great importance to older adults. As sport can provide participation opportunities across generations, it can be an ideal physical activity option for this age group. However, a major barrier is that sport policy often prioritizes the participation for younger age groups. Policymakers should include a focus on older adults, to derive social health benefits.

Sport and ageing: a systematic review of the determinants and trends of participation in sport for older adults.

BACKGROUND: The global population is ageing. As ageing is often associated with a decline in health, there is a need to further develop preventative health measures. Physical activity can positively influence older adults' (aged 50 years and older) health. Previous research on the relationship between physical activity and health for older adults has mainly focused on physical activity in general, and not specific types of exercise. Due to the social nature of sport, it may assist in improving physical, mental and social health for older adults. Sport, as a form of physical activity, has not been widely explored as a physical activity opportunity for older adults. This review concurrently explored two research questions: the determinants and the trends of sport participation for community dwelling older adults. METHODS: Two parallel systematic searches of nine electronic databases were conducted in December 2015 for the two research questions. English language quantitative and qualitative studies that provided specific results for community dwelling older adults' sport participation were included and a quality ratings assessment was undertaken. RESULTS: There were 10,171 studies initially identified for the first research question and 1992 studies for the second research question. This culminated in 18 and 8 studies respectively that met the inclusion criteria. The most frequently mentioned determinants of participation were health and using sport to negotiate the ageing process. The most frequently mentioned trends of sport participation were the effect of historical sport participation on current participation, and sport participation across the lifespan. The main themes for both research questions had contrasting results, for example, participation in sport could improve health, but poor health was also a limitation of sport participation. CONCLUSIONS: This review demonstrates that older adults are a heterogeneous age group, and therefore require different strategies than other age groups to successfully participate in sport. It is recommended that the main findings from this review are incorporated into specific strategies to develop age appropriate sporting opportunities for older adults, so that sport can be presented as a viable physical activity option for this age group.

The relationship of sport participation to provision of sports facilities and socioeconomic status: a geographical analysis.

OBJECTIVE: Ecological models have been applied to investigate multiple domains influencing physical activity behaviour, including individual, social, organisational, community, environmental and policy factors. With regard to the built environment, research to date has been limited to small geographical areas and/or small samples of participants. This study examined the geographical association between provision of sport facilities and participation in sport across an entire Australian state, using objective total enumerations of both, for a group of sports, with adjustment for the effect of socioeconomic status (SES). METHODS: De-identified membership registration data were obtained from state sport governing bodies of four popular team sports. Associations between participation rate, facility provision rate and SES were investigated using correlation and regression methods. RESULTS: Participation rate was positively associated with provision of facilities, although this was complicated by SES and region effects. The non-metropolitan region generally had higher participation rates and better provision of facilities than the metropolitan region. CONCLUSIONS: Better provision of sports facilities is generally associated with increased sport participation, but SES and region are also contributing factors. Implications for public health: Community-level analysis of the population, sport participation and provision of facilities should be used to inform decisions of investments in sports facilities.

Age profiles of sport participants.

BACKGROUND: Participation in sport has many health benefits, and is popular amongst children. However participation decreases with age. While the membership records of peak sports organisations have improved markedly in recent years, there has been little research into sport participation trends across the lifespan. This study investigates age profiles of participation in sport and compares these trends between genders and residential locations. METHODS: De-identified 2011 participant registration data for seven popular Australian sports (Australian Football, Basketball, Cricket, Hockey, Lawn Bowls, Netball and Tennis) were obtained and analysed according to age, gender and geographical location (metropolitan v non-metropolitan) within the state of Victoria, Australia. All data were integrated and sports were analysed collectively to produce broadly based participation profiles while maintaining confidentiality of membership data for individual sports. RESULTS: The total number of registered participants included in the data set for 2011 was 520,102. Most participants (64.1 %) were aged less than 20 years. Nearly one third (27.6 %) of all participants were aged 10-14 years, followed by the 5-9 year age group (19.9 %). Participation declined rapidly during adolescence. A higher proportion of males than female participants were young children (4-7 years) or young adults 18-29 years; this pattern was reversed among 8-17 year-olds. A higher proportion of metropolitan participants were engaged between the ages of 4-13 and 19-29, whereas a higher proportion of non-metropolitan participants played during adolescence (14-18 years) and throughout mature adulthood (30+ years). CONCLUSIONS: Increasing participation in sport is an objective for both government and sporting organisations. In order to have both mass population-based participation, from a health policy and elite performance perspective, we need to further explore the findings arising from the analysis of this extensive data set. Such an examination will lead to better understand of the reasons for attrition during adolescence to inform program and policy developments to retain people participating in sport, for a healthy and sport performing nation.

Stored object knowledge and the production of referring expressions: the case of color typicality.

When speakers describe objects with atypical properties, do they include these properties in their referring expressions, even when that is not strictly required for unique referent identification? Based on previous work, we predict that speakers mention the color of a target object more often when the object is atypically colored, compared to when it is typical. Taking literature from object recognition and visual attention into account, we further hypothesize that this behavior is proportional to the degree to which a color is atypical, and whether color is a highly diagnostic feature in the referred-to object's identity. We investigate these expectations in two language production experiments, in which participants referred to target objects in visual contexts. In Experiment 1, we find a strong effect of color typicality: less typical colors for target objects predict higher proportions of referring expressions that include color. In Experiment 2 we manipulated objects with more complex shapes, for which color is less diagnostic, and we find that the color typicality effect is moderated by color diagnosticity: it is strongest for high-color-diagnostic objects (i.e., objects with a simple shape). These results suggest that the production of atypical color attributes results from a contrast with stored knowledge, an effect which is stronger when color is more central to object identification. Our findings offer evidence for models of reference production that incorporate general object knowledge, in order to be able to capture these effects of typicality on determining the content of referring expressions.

Digestibility of transglutaminase cross-linked caseinate versus native caseinate in an in vitro multicompartmental model simulating young child and adult gastrointestinal conditions.

Aim of this study was to investigate the digestion of transglutaminase cross-linked caseinate (XLC) versus native caseinate (NC) in solution and in cheese spread under digestive conditions for adults and children mimicked in a gastrointestinal model. Samples were collected for gel electrophoresis and nitrogen analysis. The results showed no relevant differences between XLC and NC for total and α-amino nitrogen in digested fraction under adult and child conditions. However, the rate of digestion was depending on the food matrix. Gel electrophoresis showed the gastric breakdown of XLC without formation of pepsin resistant peptides larger than 4 kDa. NC was slowly digested in the stomach with formation of pepsin resistant fragments and was still detectable in the stomach after 90 min. In the small intestine the proteins were rapidly digested. XLC was digested to small peptides, while NC was resistant against pepsin digestion under gastric conditions of adults and children.

Sensitizing capacity and allergenicity of enzymatically cross-linked sodium caseinate in comparison to sodium caseinate in a mouse model for cow's milk allergy.

A transglutaminase cross-linked caseinate was designed for use in dairy products to increase the viscosity of food matrices. The difference in structure of cross-linked caseinate might have implications for the risk of developing cow's milk allergy. The sensitizing capacity and the allergenicity (the potency to induce an allergic effector response) of cross-linked sodium caseinate was investigated using a mouse model for cow's milk allergy. Mice were orally sensitized with cross-linked caseinate or caseinate using cholera toxin as adjuvant. Anaphylactic shock reactions, change in body temperature, acute allergic skin response, caseinate-, cross-linked caseinate-IgE and mMCP-1 concentrations were determined after challenge with cross-linked caseinate or caseinate. Sensitization with cross-linked caseinate did not result in anaphylactic shock symptoms, drop in body temperature or release of serum mMCP-1. A tendency toward decreased casein-specific IgE levels was observed. The allergenicity did not differ between both products. These results indicate that in already caseinate-sensitized mice, cross-linked caseinate did not provoke more pronounced allergenic reactions compared to sodium caseinate. On top of that, reduced sensitization to cross-linked caseinate was observed. Cross-linked caseinate might therefore be an interesting new dietary concept for humans at risk for food allergy although more mechanistic studies and clinical trials are needed for validation.
