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(More)
Research into daily physical activity (PA) patterns of older adults (≥70 years) has primarily relied on self-report. This study used accelerometry, an objective measure of minute-by-minute movement, to assess PA volume and intensity performed by older adults recruited to the Better Ageing project. Results were used to estimate the degree to which current(More)
BACKGROUND There are many health and social benefits of physical activity (PA) for older adults, but little is known about their activity patterns. PURPOSE The purpose of this study was to objectively assess the PA patterns of older adults and the lifestyle and demographic factors associated with PA. METHODS Participants (N = 230, aged 78.1 yr)(More)
Previous studies have reported a decrease in muscle torque per cross-sectional area in old age. This investigation aimed at determining the influence of agonists muscle activation and antagonists co-activation on the specific torque of the plantarflexors (PF) in recreationally active elderly males (EM) and, for comparison, in young men (YM). Twenty-one EM,(More)
BACKGROUND A key public health objective is increasing health-enhancing physical activity (PA) for older adults (OAs). Daily trip frequency is independently associated with objectively assessed PA volumes (OAs). Little is known about correlates and these trips' transport mode, and how these elements relate to PA. PURPOSE to describe the frequency,(More)
Our understanding of the relationship between physical activity and health is constantly evolving. Therefore, the British Association of Sport and Exercise Sciences convened a panel of experts to review the literature and produce guidelines that health professionals might use. In the ABC of Physical Activity for Health, A is for All healthy adults, B is for(More)
OBJECTIVE To examine the prevalence of childhood and adolescent obesity in Taiwan and investigate the association between excess weight and physical fitness and blood pressure. DESIGN Cross-sectional study. SUBJECTS A total of 13 935 children and adolescents aged 6-18 years (boys: 7031, girls: 6904) were involved in the 1999 survey and 24 586 (boys: 12(More)
Increasing evidence suggests that physical activity can prevent some aspects of mental illness in older people such as depression, dementia and Alzheimer’s disease. Additionally, limited research has shown that engagement in structured exercise can improve aspects of psychological well-being such as mood and self-perceptions in older adults. However, the(More)
BACKGROUND Physical activity has many positive effects on children's health while TV viewing has been associated with adverse health outcomes. Many children do not meet physical activity recommendations and exceed TV viewing guidelines. Parents are likely to be an important influence on their children's behaviour. There is an absence of information about(More)
