Construction and Validation of a Perceived Physical Literacy Instrument for Physical Education Teachers

dx.plos.org/10.1371/journal.pone.0155610
The purpose of this study was to construct and validate a “Perceived Physical Literacy Instrument” (PPLI) for physical education teachers. Based on literature review and focus group interviews, an 18-item instrument was developed for the initial tests. This self-report measure, using a 5-point Likert scale, formed the PPLI and was administered to 336 physical education teachers in Hong Kong. The sample was randomly split, and exploratory and confirmatory factor analyses resulted i...

Influential Factors of Insufficient Physical Activity among Adolescents with Asthma in Taiwan

dx.plos.org/10.1371/journal.pone.0116417
Purpose: Little research has been reported concerning insufficient physical activity in Taiwanese adolescents with asthma. The aims of this paper are to compare the amount of physical activity between asthmatic and non-asthmatic adolescents in Taiwan, as well as to investigate the influential factors associated with insufficient physical activity in asthmatic adolescents. Methods: Self-reporting structured questionnaires (socio-economic status, scale of family support for physical acti...

Cardiorespiratory Fitness Is Associated with Hard and Light Intensity Physical Activity but Not Time Spent Sedentary in 10–14 Year Old Schoolchildren: The HAPPY Study

dx.plos.org/10.1371/journal.pone.0061073
Background: Sedentary behaviour is a major risk factor for developing chronic diseases and is associated with low cardiorespiratory fitness in adults. It remains unclear how sedentary behaviour and different physical activity subcomponents are related to cardiorespiratory fitness in children. The purpose of this study was to assess how sedentary behaviour and different physical activity subcomponents are associated with 10–14 year-old schoolchildren's cardiorespiratory fitness. Metho...

Reliability and Validity of the Transport and Physical Activity Questionnaire (TPAQ) for Assessing Physical Activity Behaviour

dx.plos.org/10.1371/journal.pone.0107039
Background: No current validated survey instrument allows a comprehensive assessment of both physical activity and travel behaviours for use in interdisciplinary research on walking and cycling. This study reports on the test-retest reliability and validity of physical activity measures in the transport and physical activity questionnaire (TPAQ). Methods: The TPAQ assesses time spent in different domains of physical activity and using different modes of transport for five journey purpo...

Does the Benefit on Survival from Leisure Time Physical Activity Depend on Physical Activity at Work? A Prospective Cohort Study

dx.plos.org/10.1371/journal.pone.0054548
Purpose: To investigate if persons with high physical activity at work have the same benefits from leisure time physical activity as persons with sedentary work. Methods: In the Copenhagen City Heart Study, a prospective cohort of 7,411 males and 8,916 females aged 25–66 years without known cardiovascular disease at entry in 1976–78, 1981–83, 1991–94, or 2001–03, the authors analyzed with sex-stratified multivariate Cox proportional hazards regression the association between ...

Confusion and Conflict in Assessing the Physical Activity Status of Middle-Aged Men

dx.plos.org/10.1371/journal.pone.0004337
Background: Physical activity (including exercise) is prescribed for health and there are various recommendations that can be used to gauge physical activity status. The objective of the current study was to determine whether twelve commonly-used physical activity recommendations similarly classified middle-aged men as sufficiently active for general health. Methods and Findings: We examined the commonality in the classification of physical activity status between twelve variations of ...

Towards Integrated Physical Activity Profiling

dx.plos.org/10.1371/journal.pone.0056427
Recently, there has been some discussion of whether it is possible to score highly in one dimension of physical activity behaviour (e.g., moderate intensity exercise) whilst also scoring poorly in another (e.g., sedentary time). Interestingly, direct empirical observations to support these proposals are lacking. New technologies now enable the capture of physical activity thermogenesis on a minute-by-minute basis and over a sustained period. We used one of the best available t...

Leisure-Time Physical Activity and All-Cause Mortality

dx.plos.org/10.1371/journal.pone.0101548
Background: Physical inactivity is a major public health problem associated with increased mortality risk. It is, however, poorly understood whether vigorous physical activity is more beneficial for reducing mortality risk than activities of lower intensity. The aim of this study was to examine associations of the intensity and volume of leisure-time physical activity with all-cause mortality among middle-aged women and men while considering sociodemographic and health related factors ...

Physical Activity and Its Correlates among Adults in Malaysia: A Cross-Sectional Descriptive Study

dx.plos.org/10.1371/journal.pone.0157730
Obesity and rates of non-communicable diseases linked to physical inactivity have increased dramatically in Malaysia over the past 20 years. Malaysia has also been identified as one of the least physically active countries in the world with over 60% of adults being essentially sedentary. This study examines the relationship of socio-demographic factors to physical activity among 770 adults from 3 Malaysian states. Physical activity levels were significantly related to ethnicity, gende...
