- Description: Culturally and linguistically diverse (CALD) migrants face significant health risks as they adapt to new cultures. These risks are exacerbated by their limited participation in preventative behaviours such as sports and physical activity. The review aimed to identify studies that examined the correlates of sport and physical activity participation in migrants. The systematic review identified 72 papers, including 6 interventions, 18 qualitative and 48 quantitative studies. The 44 identified correlates highlight the complexities involved in working with migrants. The correlates were grouped in four themes using the social ecological model; acculturation, demographic, psychosocial and environmental/organisational. The social ecological model identified general correlates such as social support and safety. However, there were unique correlates relating to individuals who are facing cultural changes such as acculturation and language. Overall, there is a lack of contextualisation of CALD migrants' sport and physical activity experiences because many studies fail to consider acculturation comprehensively.

- 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: There is evidence that an acute bout of exercise confers cognitive benefits, but it is largely unknown what the optimal mode and duration of exercise is and how cognitive performance changes over time after exercise. We compared the cognitive performance of 31 older adults using the Stroop test before, immediately after, and at 30 and 60 min after a 10 and 30 min aerobic or resistance exercise session. Heart rate and feelings of arousal were also measured before, during, and after exercise. We found that, independent of mode or duration of exercise, the participants improved in the Stroop Inhibition task immediately postexercise. We did not find that exercise influenced the performance of the Stroop Color or Stroop Word Interference tasks. Our findings suggest that an acute bout of exercise can improve cognitive performance and, in particular, the more complex executive functioning of older adults.

- Description: A number of studies have reported a co-occurrence between video game addiction and poorer mental health, but few have contextualised this relationship by identifying mediating variables. Further, there remains uncertainty in how to differentiate high engagement from what may be termed addiction in the context of video gaming. This study examined the mediating role of coping between one measure of video game addiction and engagement, and mental health. An international sample of 552 adult participants (M age 24.9 years, 52.3 % Australian) completed an online survey including the Computer Addiction-Engagement Scale (CAES), Depression, Anxiety Stress Scale (DASS-21) and Approach/Avoidance Coping Questionnaire (BACQ). Multiple mediation analysis showed that coping explained a significant portion of the relationship between video game addiction and symptoms of depression, anxiety and stress. However, even after accounting for coping, a direct relationship remained. Video game engagement, on the other hand, indicated full mediation with no direct connection to declined mental health, except in the case of anxiety. Less use of approach coping strategies and particularly more use of resignation and withdrawal coping strategies were related to poorer mental health. Gaming for distraction was unrelated to mental health. This study identified maladaptive coping as a partial explanation of the relationship between video game addiction and poorer mental health. Also, the findings provide validity for making a distinction between video gaming engagement and addiction. Highly engaged gamers with maladaptive coping styles may be more vulnerable to developing video game addiction.

- Description: Objective: To investigate the feasibility, effectiveness, and short-term effects of an exercise intervention using a novel exercise park in improving seniors’ balance, physical function, and quality of life. Method: Randomized controlled trial with pre- and post-intervention design (baseline and 18-week intervention) was used. Outcome measures included measures of balance, strength, and function, as well as quality of life and fear of falling. MANCOVA was used to assess differences between groups (control and exercise intervention) over time. Results: Intervention group showed significant improvement on single leg stance (p = .02, 95% confidence interval [CI] = [−8.35, −0.549]), knee strength (p < .01, 95% CI = [−29.14, −5.86]), 2-min walk (p = 0.02, 95% CI = [−19.13, −0.859]), and timed sit to stand (p = .03, 95% CI = [−2.26, −0.143]) tests. Discussion: The exercise park program improved physical function and had high adherence and participation rate. Such intervention has been shown to be safe and therefore might enhance participation in exercise programs for older adults.

- Description: Against the backdrop of a global physical inactivity crisis, attempts to both understand and positively influence physical activity behaviours are characterized by a focus on individual-level factors (e.g. cognitions, attitudes, motivation). We outline a new perspective, drawn from an emerging body of work exploring the applicability of social identity and self-categorization theories to domains of sport and health, from which to understand and address this pervasive problem. This social identity approach suggests that the groups to which people belong can be, and often are, incorporated into their sense of self and, through this, are powerful determinants of physical activity-related behaviour. We start by reviewing the current state of physical activity research and highlighting the potential for the social identity approach to help understand how social factors influence these behaviours. Next, we outline the theoretical underpinnings of the social identity approach and provide three key examples that speak to the analytical and practical value of the social identity approach in physical activity settings. Specifically, we argue that social identity (1) can be harnessed to promote engagement in physical activity, (2) underpins exercise group behaviour, and (3) underpins effective leadership in exercise settings. We conclude by identifying prospects for a range of theory-informed research developments.

- Description: Abstract 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 comparison group. Design This study used a non-randomised control design. The intervention and comparison groups were drawn from three primary schools. The study followed the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) statement for reporting. Methods A total of 333 children (51% girls, 41% intervention) with a mean age of 8.1 years ( sd = 1.1) participated. Intervention children (16 weeks x 2 hrs of gymnastics) were compared to children who received (16 × 2 hrs) standard PE curriculum. Children's movement competence was assessed using the Test of Gross Motor Development–2, Stability Skills Assessment and the Körper-Koordinationstest für Kinder. Multilevel linear mixed models, accounting for variation at the class level and adjusted for age and sex, were used to assess intervention relative to comparison differences in all aspects of movement competence. Results Stability and object control skills showed a significant ( p < .05) intervention x time interaction effect. No difference was found in locomotor skills or general coordination. Conclusions Gymnastics is effective at developing stability skills and object control skills without hindering the development of locomotor skills or general coordination. Accelerated learning of stability skills may support the development of more complex movement skills.

- Description: The physical, mental, cognitive, and health benefits of regular physical activity, exercise and sport participation are today well documented. Regular exercise positively influences most of our physiological systems and helps in protecting against, and rehabilitation of, several chronic diseases including cardiovascular disease, numerous cancers, diabetes, stroke, and metabolic disorders (e.g., obesity). It also builds muscle and strengthens bones, preventing osteoporosis. In the elderly, it helps in maintaining balance, thereby reducing the risk of falls and maintaining independent living. This is particularly important as falls and related injuries are the leading cause of mortality and morbidity in people aged 65 years and older. Exercise also helps to alleviate symptoms of anxiety and depression and buffers against stress. Moreover, there is good evidence to suggest that regular exercise maintains brain integrity and improves cognitive functioning across the lifespan. It has been suggested that, if exercise could be packed into a pill, it would be the single most widely prescribed and beneficial medicine. Regular exercise appears to be a ‘magic bullet’ for human health and well-being. Physical inactivity or sedentary behaviour, on the other hand, is also an important cause of health problems in Western societies. The amount of sedentary behaviour we engage in on a daily basis (e.g., watching television, surfing the internet, reading, or playing videogames), independent of how much physical activity or exercise we do, predicts ill health. For instance, a large longitudinal Canadian study showed that those who sat a very long time in one block had a 50 per cent increase in mortality in comparison to those who sat for shorter periods in one block. This study showed a dose–response relationship (positive correlation) between sitting time (duration of blocks) and ill health, which was independent of the amount of physical activity people engaged in (Katzmarzyk, Church, Craig, and Bouchard, 2009). This suggests that the time we spend sitting and its distribution across the day is related to morbidity and mortality, independent of being less or more physically active. This is why many governments across the globe have developed campaigns to promote physical activity, exercise, and sports. In this chapter, we will demonstrate that social psychologists can contribute in important ways to reach these goals.

- Description: This study evaluated the effectiveness of an 8-week gymnastics curriculum on children's movement competence and their physical self-concept. There were 113 children (46% girls, 49% intervention) with a mean age of 9.4 years (SD = 1.8) that participated. Intervention children underwent 8 weeks of gymnastics and the comparison group continued with their standard curriculum. Age was a significant co-variate, a separate analysis was conducted on the lower (grades 2 and 4) and upper (grade 6) groups. The lower age group showed significant improvement in favor of the gymnastic group in fundamental movement skills. The upper age group showed a significant improvement for the control group in general body coordination and fundamental movement skills. For all grades, the physical self-concept showed a significant main effect in favor of the gymnastics group. The gymnastics intervention was found to be of particular benefit for developing children's movement competence and physical self-concept in younger children.

- Description: This study examines the nature and impact of sexist and homophobic discrimination experienced by lesbians, gays and bisexuals (LGB) in Australian sporting settings. A mixed methods online survey was utilized to collate participant experiences. The findings suggest that, in sport, participants experienced sexism directly and systemically, and homophobia explicitly and implicitly. Women experienced sexism and homophobia, whilst men reported more homophobic events. The most mentioned impacts of discrimination were negative emotions such as sadness, anger, distress and shame, followed by negative engagement with sport such as disliking sport, or avoiding or leaving sport. The well-recognized benefits of sport such as physical and mental well-being, social connections, enjoyment, positive identity and achievement may be more difficult to realize within this context of significant social stress.

- Description: Introduction. Coaching behaviour, motivational climate and its influence towards performance satisfaction are important in understanding the development and growth of athletes. In general, positive coaching behaviours could help in enhancing the motivational climate and satisfaction of athletes while negative coaching behaviour might have the opposite effect. Therefore, this study explored the influence of volleyball coaches’ behaviour on elite volleyball players’ motivational climate and performance satisfaction. Methodology. Three hundred and twenty-eight elite volleyball players (137 male and 191 female, age: 24.42 ± 8.92 years old) participated in this study. They completed three questionnaires: the Coaching Behaviour Questionnaire (CBQ), Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2), and Athlete Satisfaction Questionnaire (ASQ). These questionnaires were used to assess athletes’ perceptions of their coaches’ behaviour, to examine the influence of athletes’ perceptions of the individual feedback received on their perceptions of the team’s motivational climate and to measure the elite volleyball players’ satisfaction of their team’s performance. Results & Discussion. There was a positive relationship between motivational climate and performance satisfaction (r=0.25) coaching behaviour and performance satisfaction (r=0.26) motivational climate and performance satisfaction (r=0.40). For CBQ, the mean score showed that coach support (2.97 ± 0.40) was the most important as compared to negative coaching behaviour (2.44 ± 0.45). For ASQ, the mean score showed that team integration (5.33 ± 1.00) was the most important subscale influencing athlete satisfaction. The lowest rated athlete satisfaction was external agents, example, facilities and supporters (4.56 ± 0.95). For PMCSQ-2, a higher mean was reported for task-involving climate, example, cooperative learning, effort/improvement, important role (5.36 ± 0.89) than ego-involving climate, example, intra-team member rivalry, unequal recognition, punishment for mistakes (4.09 ± 0.95). Conclusion. Coaches should look into their own coaching behaviour because it is a fundamental aspect in enhancing the performance of athletes with respect to motivational climate and performance satisfaction.

- Description: We investigated (1) the relationship between Type D personality, stress intensity appraisal of a self-selected stressor, coping, and perceived coping effectiveness and (2) the relationship between Type D personality and performance. In study one, 482 athletes completed the Type D personality questionnaire (DS14), stress thermometer and MCOPE in relation to a recently experienced sport stressor. Type D was associated with increased levels of perceived stress and selection of coping strategies (more emotion and avoidance coping) as well as perceptions of their effectiveness. In study two, 32 participants completed a rugby league circuit task and were assessed on pre-performance anxiety, post-performance affect and coping. Type D was associated with poorer performance (reduced distance more errors), decreases in pre-performance self-confidence and more use of maladaptive resignation/withdrawal coping. Findings suggest that Type D is associated with maladaptive coping and reduced performance. Type D individuals would benefit from interventions related to mood modification or enhancing interpersonal functioning.

- Description: Exercise is effective in preventing falls among older adults. However, few studies have included people living with dementia and their carers and explored their experiences. The aim of this study is to explore what affects the acceptability of exercise interventions to better meet the needs of people with dementia and their carers as a dyad. Observations, field notes containing participant's and instructor's feedback, and focus groups with 10 dyads involved in Tai Chi classes for 3 or 4 weeks in two sites in the South of England were thematically analyzed to understand their experiences. Findings suggest that dyads' determination to achieve the benefits of Tai Chi facilitated their adherence, whereas a member of the dyad's low sense of efficacy performing the movements during classes was a barrier. Simplifying class content and enhancing the clarity of instructions for home-based practice will be key to support the design of future exercise interventions. © 2019 The Authors.

- Description: Objectives: This study investigated cognitions of cyclists during a competitive time trial (TT) event using Think Aloud (TA) protocol analysis. Design: Single group, observational design. Method: Fifteen male and three female cyclists from the North West of England verbalised their thoughts throughout an outdoor competitive 16.1 km cycling TT (Level 2 TA). Verbalisations were recorded using iVue Horizon 1080P camera glasses. Data were transcribed verbatim, analysed using deductive content analysis and grouped into themes: (i) Pain And Discomfort (Fatigue, Pain), (ii) External Feedback (Time, Speed, Heart Rate), (iii) Environment (Surroundings, Traffic and Other Cyclists), and (iv) Pace and Distance (Pace, Distance). The number of verbalisations within each theme was analysed by distance quartile using Friedman tests to examine changes in cognitions over time. Results: Associative themes, including Fatigue and Pain, were verbalised more frequently in the earlier stages of the TT and less in the final quartile, whereas verbalisations about Distance significantly increased in the last quartile. Conclusions: This study demonstrates how a novel data collection method can capture in-event cognitions of endurance athletes. It provides an important extension to previous literature, showing how individuals may process and attend to information over time during an exercise bout. Future research should establish the relationship between performance and cognitive processes. © 2017, © 2017 International Society of Sport Psychology.

- Description: There is growing evidence that leaders' effectiveness derives in part from their creation of a sense of identity that is shared by members of a group they are attempting to lead (i.e., their identity entrepreneurship). Little is known, however, about the impact of identity entrepreneurship in sport and exercise settings, particularly in relation to its effect on group members' effort and performance. Using a pre-post between subjects experimental design, we examined the effect of leaders' identity entrepreneurship on group members' effort and performance during 5km cycling time trials. Following a baseline session (in which time trials were completed individually), participants (N = 72) were randomly allocated to either a high or low identity entrepreneurship condition, and further randomly divided into groups of five (including a leader who was a confederate). In the subsequent test sessions (which participants attended with their fellow group members), leaders displayed either high or low identity entrepreneurship behaviors. Results indicated that, compared to participants in the low identity entrepreneurship condition, those in the high identity entrepreneurship condition maintained greater effort (maximum heart rate), and demonstrated improved (rather than poorer) performance (average power output in the first 60 seconds of time trials). Examination of pacing showed that the largest increases in participants' average power output occurred in the early stages of their second time trials for those in the high identity entrepreneurship condition only. Results provide causal evidence that leaders who create a shared sense of identity among team members are able to inspire greater participant effort and performance. © 2019 Stevens et al.
