“Men Need Role Models”
Yoga is a holistic form of physical activity taken up for various reasons, including physical and mental health, and sometimes spirituality. Despite the growing popularity of yoga as a form of health-enhancing physical activity, data show the uptake among men to be consistently low compared to women. To gain an understanding of barriers and facilitators for yoga uptake and adherence among men, four focus group discussions (three male groups, one …

The Feasibility of a Text-Messaging Intervention Promoting Physical Activity in Shift Workers
Workplace health promotion programs (WHPPs) can improve shift workers' physical activity. The purpose of this paper is to present the process evaluation of a text messaging health promotion intervention for mining shift workers during a 24-day shift cycle. Data collected from intervention participants with a logbook ( n = 25) throughout the intervention, exit interviews ( n = 7) and online surveys ( n = 17) examined the WHPP using the RE-AIM (Rea…
The Cost-Effectiveness of the SMART Work & Life Intervention for Reducing Sitting Time
Sedentary behaviours continue to increase and are associated with heightened risks of morbidity and mortality. We assessed the cost-effectiveness of SMART Work & Life (SWAL), an intervention designed to reduce sitting time inside and outside of work, both with (SWAL-desk) and without (SWAL-only) a height-adjustable workstation compared to usual practice (control) for UK office workers. Health outcomes were assessed in quality-adjusted life-years …
For Exercise, Relaxation, or Spirituality
Yoga is a traditional practice from India with the potential to promote physical activity and health. Participation worldwide remains low, particularly among men. To better understand yoga participation parameters, with a special focus on what influences male participation, this study examined gender differences in participation motives and conformity to masculine norms. It also explored these factors across three participant subgroups who differ…
Views of the public about SnacktivityTM

Self-reported disability and its association with obesity and physical activity in Australian adults
Obesity imposes a significant toll on adult Australians' health. This risk factor of disability can be reduced through public health interventions
Age and gender differences in the relationship between obesity and disability with self-perceived employment discrimination
The results provide evidence that obesity and disability contribute to employment discrimination in Australia. The findings can assist government and related agencies to consider the adequacy of existing discrimination legislation and help organisations to develop appropriate policies to address discrimination against obese and disabled people in their workplaces
Modelling the Reallocation of Time Spent Sitting into Physical Activity
Isotemporal substitution modelling (ISM) and compositional isotemporal modelling (CISM) are statistical approaches used in epidemiology to model the associations of replacing time in one physical behaviour with time in another. This study's aim was to use both ISM and CISM to examine and compare associations of reallocating 60 min of sitting into standing or stepping with markers of cardiometabolic health. Cross-sectional data collected during th…
Adolescents’ physical activity and sedentary behaviour in Indonesia during the Covid-19 pandemic
During the pandemic, mothers perceived their children to be less active and using more screen-based devices, either for educational or recreational purposes, compared to before. The present themes might be useful when developing interventions and policies promoting physical activity and reducing sedentary behaviour in adolescents. Interventions could, for example, consider increasing parents' and adolescents' awareness on current activity guideli…

Physical activity and mental health in children and adolescents
Controversies in the Science of Sedentary Behaviour and Health
The development in research concerning sedentary behaviour has been rapid over the past two decades. This has led to the development of evidence and views that have become more advanced, diverse and, possibly, contentious. These include the effects of standing, the breaking up of prolonged sitting and the role of moderate-to-vigorous physical activity (MVPA) in the association between sedentary behaviour and health outcomes. The present aim is to…

Office workers’ experiences of attempts to reduce sitting-time
ISRCTN29395780 (registered 21 November 2016)
Clustering and correlates of screen-time and eating behaviours among young children
Screen-time and unhealthy dietary behaviours are highly pervasive in young children and evidence suggests that these behaviours often co-occur and are associated. Identifying clusters of unhealthy behaviours, and their influences early in childhood, can assist in the development of targeted preventive interventions. The purpose of this study was to examine the sociodemographic, behavioural, and home physical environmental correlates of co-occurri…

Physical activity and sedentary behaviour research in Thailand
The number of Thai papers on PA published per year has been increasing, indicating a growing interest in this research area. More studies using population-representative samples are needed, particularly among children and adolescents, and investigating SB as a health risk factor. To provide stronger evidence on determinants and outcomes of PA/SB, longitudinal studies using standardised measures of PA and SB are required
Adolescent girls' perceptions of physical activity
Low levels of physical activity among adolescent girls are a cause for concern. Examining girls' physical activity perceptions and motivations through in-depth qualitative research allows for greater understanding of the reasons behind their physical activity-related choices. Forty-seven girls aged 14 to 16 years participated in exploratory focus group discussions. Thematic analysis was carried out in which data were analysed inductively using a …

Perceived locus of causality, goal orientations, and perceived competence in school physical education classes
Ryan & Connell (1989) have demonstrated that different types of behavioural regulation can be located on a continuum of perceived autonomy or perceived locus of causality. The present study applied their formulation in the context of school physical education (PE) and examined the relationships of perceived autonomy, perceived competence and goal orientations with intrinsic interest across two PE activities. School students aged 12-14 years (N=85…
Individual, behavioural and home environmental factors associated with eating behaviours in young adolescents
This study aimed to examine individual, behavioural and home environmental factors associated with frequency of consumption of fruit, vegetables and energy-dense snacks among adolescents. Adolescents aged 11-12 years (n = 521, 48% boys) completed a paper-based questionnaire during class-time which included a Food Frequency Questionnaire assessing their consumption of fruit, vegetables, and energy-dense (ED) snacks, and items assessing habits, sel…
The Cognitive Processes by which Perceived Locus of Causality Predicts Participation in Physical Activity
The present study examined the cognitive processes by which perceived locus of causality influences participation in leisure time physical activity. Based on the theoretical tenets of self-determination theory, it was hypothesized that deliberative modes of information processing and past behaviour will account for the direct effects of perceived locus of causality on effort and physical activity. Data from self-report questionnaires were analyse…
Family circumstance and adolescent dietary behaviours
The available information on the contribution of family circumstance to adolescent dietary behaviours is inconsistent. Indicators of family circumstance may impact adolescent behaviours by influencing their daily home environment. This study examined cross-sectional and longitudinal relationships between indicators of family circumstance and (i) breakfast skipping and (ii) consumption of snack food, fast food, fruits and vegetables among adolesce…
Intrinsic Motivation towards Sports in Singaporean Students
This study investigated determinants of active lifestyles in Singaporean university students. Using confirmatory factor analysis, a measure of lay beliefs concerning athletic ability was confirmed. Other results confirmed hypotheses that beliefs reflecting that athletic ability can be developed over time (incremental beliefs) predict an achievement task (selfreferenced) orientation, while beliefs reflecting that athletic ability is relatively sta…
Physical Self-Perceptions in Adolescence
This study examines the generalizability of the form, structural parameters, and latent means of a hierarchical multidimensional model of physical self-perceptions in adolescents from three cultures. A children's version of the physical self-perception profile (PSPP-C) was administered to samples of British, Hong Kong, and Russian high school students. A structural equation model that hypothesized a hierarchical structure with global self-esteem …
Exercise and health psychology
The increasing prominence of health psychology has been paralleled by developments in the study of the psychology of health‐related exercise. Evidence has been amassed which supports the efficacy of regular physical activity in reducing the risks of some debilitating health conditions such as coronary heart disease and obesity, as well as the promotion of physical function and mental well‐being. The significance of exercise as a health‐related be…

Assessment of Children's Physical Self-Perceptions
Two studies are reported on the use of Fox and Corbin's (1989) Physical Self-Perception Profile (PSPP) modified for use with children (PSPP-C). The current studies used British children of 12 and 15 years of age. Study I found that after factor analysis the proposed four subdomains of physical self-worth (sport competence, body attractiveness, perceived strength and physical condition) were not clearly represented, although some similarities emer…
Children's task and ego goal profiles in sport
The purpose of this study was to examine the combined effects of task and ego goal orientations on children's sport motivation. Participants were 115 boys and 116 girls (mean age = 11.12 yrs). Unlike previous research, where the correlates of the two orientations have been examined separately, this study examined the motivational consequences of different task and ego combinations. Four groups were created based on mean splits on the task and ego…

Changes in Attributions, Perceptions of Success and Intrinsic Motivation after Attribution Retraining in Children's Sport
Despite great interest in recent years in research on attributions for success and failure in sport, little investigation has taken place on changing attributions for the purpose of promoting motivation or avoiding demotivation. This study reports on an attribution retraining intervention with 12 boys and girls, aged 11–12 years, selected from an initial sample of 58. Six children who rated their success on a ball dribble task as low, and had ‘ma…
Functional significance of psychological variables that are included in the Theory of Planned Behaviour
The Theory of Planned Behaviour was proposed by Ajzen (1985) in an attempt to expand the applicability of the Theory of Reasoned Action (TRA) to situations where behaviour is not under complete volitional control. However, recent research does not address the issue of the stability of intentions, yet this is considered a boundary condition of the TRA on theoretical grounds. Therefore, the purposes of the present article were, first, to make a the…

The Processes by Which Perceived Autonomy Support in Physical Education Promotes Leisure-Time Physical Activity Intentions and Behavior
The trans-contextual model proposes that young people's perceived autonomy support in physical education will affect their perceived locus of causality, intentions, and physical activity behavior in leisure time. High school students completed measures of perceived autonomy support and perceived locus of causality in physical education. One week later, participants' perceived locus of causality and constructs from the theory of planned behavior w…

Health-enhancing physical activity and sedentary behaviour in children and adolescents
We provide a wide-ranging review of health-related physical activity in children and adolescents using a behavioural epidemiology framework. In contrast to many other reviews, we highlight issues associated with true sedentary behaviours alongside physically active behaviours. Specifically, we review the evidence concerning the links between physical activity and cardiovascular disease, overweight and obesity, psychosocial measures, type II diabe…
Pubertal development and sedentary behaviour during adolescence
