Abstract: To investigate the longitudinal effect of sport participation in physical activity, fitness and body fat changes during childhood and adolescence. Longitudinal study (134 boys, 155 girls) of Australian youth aged 8-16 years. Physical activity was assessed by pedometers and accelerometers, fitness by the 20m shuttle-run, body fat by DEXA and club sport participation by questionnaire. Linear mixed models were used to determine the effects of sport participation and gender differences. Sports club participants were more physically active at all age groups than non-participants boys took an extra 1800 steps (p<0.001) and girls 590 steps per day (p<0.01) and boys engaged in an extra 9min and girls 6min more moderate to vigorous PA per day (both p<0.05). Fitness was higher among sports participants (boys 27% and girls 20% higher, both p<0.001) and sport participant girls had 2.9% less body fat (p<0.05). Higher fitness scores were maintained over time by sports participants but their greater PA diminished during adolescence, this being more evident among girls. Only 20% of sports club participants met the recommended daily average of 60min MVPA. Sport participants were more active, fitter and had less body fat (girls only) than non-sports participants. However, the associated benefits of sport with PA diminished during adolescence and the majority of sports participants did not meet recommended levels of PA. Strategies aiming to maximise the benefits of sports participation may be enhanced by providing special attention to the early adolescent period particularly among girls.

Abstract: Children's fundamental movement skill levels (FMS) predict moderate-to-vigorous physical activity (MVPA). Asian children have been reported as less active than English-Europeans, possibly due to poorer skills. This study compared the FMS of children from Culturally and Linguistically Diverse (CALD) backgrounds and examined FMS correlates. A total of 261 children (122 males) aged 9-to-11 years were ided based on language spoken at home: English-European (n = 105) and Asian (n = 156). Height, mass, FMS (Test of Gross Motor Development-2), MVPA (accelerometer) and cardio-respiratory fitness (20m multistage shuttle run) were directly measured. Sex, age, language and perceived sport competence (CY-PSPP) were self-reported. Independent s le t-tests assessed age, BMI, FMS and perception by CALD group. Linear mixed models examined FMS correlates. Asian-speaking children had lower object control skill (35.5 v 37.2 CI [0.17, 3.18] p < 0.03) compared to English-European- children, but no between-group differences in locomotor skills were observed. Fitness, physical activity and sport competence perception were positively associated with object control, yet adjusting for these variables (and age and BMI) did not remove the CALD effect (B = -2.02, SE = 0.69, p = 0.004). Cultural factors may affect object control competence in Asian-Australian children.

Abstract: We investigated longitudinal and cross-sectional relationships between eye-hand coordination (EHC) and cardiorespiratory fitness (multistage run), physical activity (pedometers), percent body fat (%BF, dual energy x-ray absorptiometry), body image, and organized sport participation (questionnaires) in 406 boys and 384 girls at 8 and 10 years of age. EHC was measured by a throw and wall-rebound catch test involving 40 attempts of increasing difficulty. Median EHC improved during two years from 18 to 32 (boys) and 9 to 24 (girls), and gender differences and improvements were both significant (P < 0.001). Cross-sectional analyses showed that boys and girls with better EHC were fitter (P < 0.001), and a longitudinal relationship showed that girls who improved their EHC over the two years became fitter (P 0.3). Finally, even at age 8 years, boys and girls participating in organized sport possessed better EHC than non-participants. These data provide evidence for the premise that early acquisition of this single motor skill promotes the development of a child's fitness, body image, and participation in sport.

Abstract: Engaging in classroom‐based physical activity (PA) breaks may help increase children's subjective wellbeing and enjoyment of PA, important precursors for children to remain engaged in PA. We conducted a systematic review to investigate the effect of brief classroom‐based PA interventions on primary school children's subjective wellbeing and enjoyment of PA. Databases were reviewed between the earliest date of records and April 2020. Eligibility criteria included peer‐reviewed empirical quantitative or mixed methods studies reporting enjoyment of PA or wellbeing outcomes of participating in a brief classroom‐based PA program. Fifteen papers were included. Interventions supported 7022 child participants enrolled at baseline and 6286 children analyzed in interventions across 148 schools. Thirteen studies examined the effect of brief classroom‐based PA interventions on subjective wellbeing. Four found a significant positive effect for children in the intervention group (specifically for children's self‐efficacy in learning with video exercises, quality of life, and self‐confidence). Eight studies examined the effect of brief classroom‐based PA interventions on enjoyment of PA. Five studies reported a positive effect for children in the intervention group and only 1 study found a negative effect for 1 grade level of children in the intervention group. The remaining studies with wellbeing and/or enjoyment outcomes reported no significant effect. Findings from these studies indicate that the integration of brief PA breaks may support PA enjoyment and specific self‐beliefs and quality of life perceptions that contribute to children's subjective wellbeing. However, more research is needed to confirm this effect.

Abstract: The aim of this study was to understand the relationship between psychosocial factors, including mental health, pain cognitions and social support associated with menstrual pain severity in women with dysmenorrhea of no identified medical cause (primary dysmenorrhea PD) and dysmenorrhea related to endometriosis. Participants included 1192 women aged 18-50 years with menstrual pain, recruited to an online cross-sectional survey in 2019. Questionnaires assessed self-reported menstrual pain severity, depression, anxiety, stress, pain catastrophizing, and social support. Women with endometriosis had significantly higher menstrual pain severity (p < 0.001) and pain catastrophizing (p < 0.001) than women with PD. Of the psychosocial factors, only pain catastrophizing (specifically, the helplessness sub-scale) predicted menstrual pain severity in each group. Overall, 36% of women with PD and 58% with endometriosis had clinically relevant levels of pain catastrophizing. Findings suggest a common psychological mechanism in women with menstrual pain, regardless of etiology. Interventions to reduce pain helplessness may be beneficial in supporting women with dysmenorrhea.

Abstract: Objectives. We determined whether physical education (PE) taught by specialists contributed to academic development and prevention of obesity in elementary school children. Methods. Our 2-year longitudinal study involved 620 boys and girls initially in grade 3 in Australia, all receiving 150 minutes per week of PE. One group (specialist-taught PE n = 312) included 90 minutes per week of PE from visiting specialists the other (common-practice PE n = 308) received all PE from generalist classroom teachers. Measurements included percentage of body fat (measured by dual-emission x-ray absorptiometry) and writing, numeracy, and reading proficiency (by government tests). Results. Compared with common-practice PE, specialist-taught PE was associated with a smaller increase in age-related percentage of body fat (P = .02). Specialist-taught PE was also associated with greater improvements in numeracy (P .03) and writing (P = .13) scores. There was no evidence of a reading effect. Conclusions. The attenuated age-related increases in percentage of body fat and enhanced numeracy development among elementary school children receiving PE from specialists provides support for the role of PE in both preventive medicine and academic development.

Abstract: Inflammatory bowel disease (IBD) is a chronic gastrointestinal disorder. Standard treatment focuses on reducing the inflammatory burden, however, not all patients respond adequately to conventional medical therapy. These patients, referred to as Patients at Risk of Suboptimal Outcomes (PARSO), have not been studied collectively. The present study aimed to understand the biopsychosocial characteristics of patients with IBD at risk of sub-optimal outcomes for targeted multi-disciplinary treatment to encourage optimal outcomes. Two cross-sectional online surveys, including 760 PARSO and 208 control (non-PARSO) participants, were conducted and their data combined. Biopsychosocial factors included quality of life, pain, disease activity, wellbeing, fatigue, stress, social support, and sleep difficulties. Results suggest that active disease, quality of life, stress, social support, sleep difficulties, fatigue, wellbeing, smoking status, IBD subtype, and pain are significantly associated with membership in a subgroup of PARSO. We also used logistic regression to explore variables associated with the total likelihood of PARSO status. Overall, the model predicted the at-risk status to a substantial degree (

Abstract: Stress and depression can affect an in idual's level of physical activity and fitness, which may place them at risk of developing cardiovascular disease. This study investigates the longitudinal effects of stress and depression on physical activity and cardiorespiratory fitness among youth. Six hundred and seventy-six children, initially aged 8 years, from the LOOK study completed a modified version of the Children's Depression Inventory, the Children's Stress Questionnaire, and objective physical activity and cardiorespiratory fitness assessments on three occasions, every 4 years. Depressive symptoms had a direct effect (longitudinal) on the cardiorespiratory fitness of girls, with a similar trend for boys. In cross-sectional analyses, a child who identified with more symptoms of depression and stress was likely to be less fit and less physically active, which in girls extended to less moderate-to-vigorous physical activity. Our findings, that both physical activity and fitness are impacted by depression and stress may contribute to strategies directed towards achieving enhanced physical activity and reductions in obesity.

Abstract: Addressing high and stagnant physical inactivity rates remains a pervasive challenge for researchers, and a priority for health organisations, governments, and physical activity practitioners. Leaders are a prevailing feature of numerous physical activity contexts and can fundamentally influence people’s physical activity behaviours and experiences. In line with this, fitness companies and organisations commonly claim that the leaders of their classes, groups, or sessions will motivate, inspire, and ensure exercisers achieve their goals. We argue, however, that there is insufficient evidence regarding how leaders can best facilitate positive behaviours among, and outcomes for, group members to be confident that these claims are translating into strong physical activity leadership on the ground. In this article, we therefore call for research that equips leaders with greater knowledge and practical guidelines for how to maximise their effectiveness. To facilitate such research, we provide an overview of research that has examined the most effective ways for physical activity leaders to promote health-enhancing behaviours (e.g. greater participation) and positive experiences that may lead to such behaviours (e.g. greater exercise enjoyment) among those they lead. Then, with the shortcomings of this extant research in mind, we outline four broad recommendations for future research: (a) conduct research in novel and varied contexts, (b) focus on insufficiently active populations, (c) utilise qualitative methods, and (d) focus on translation and implementation. Such research would, we believe, generate knowledge that enables physical activity leaders to capitalise on their potential to be powerful agents of behaviour change.
