Psychosocial Determinants and Perceived Environmental Barriers as Mediators of the Effectiveness of a Web-Based Tailored Intervention Promot...
The aim was to examine if psychosocial determinants (attitudes, self-efficacy, social support from a sports partner) and perceived environmental barriers (PEB) of physical activity (PA) mediated the effect of a 3-month Internet-based intervention on PA in European adolescents. A sample of 536 adoles...
Physical activity in a large sample of adults with intellectual disabilities.
We sought to characterize PA in adults with ID and examine the associations between self-reported activity types, objectively-measured PA, and objectively-measured body mass index (BMI). Self-reported PA and BMI were measured on 294 adults with ID. Accelerometry was collected on 131 of those partici...

Our analysis supports daily walking as the preferred PA for achieving a healthy rate of GWG....
The relations of suicidal ideation and attempts with physical activity among Korean adolescents.
Suicide is the leading cause of death among Korean adolescents. This study investigates the cross- sectional relations of physical activity with suicidal ideation and attempts in adolescents, simultaneously considering previously reported risk factors of suicide such as depression, stress, and body...
School physical activity policy assessment.
We developed and assessed reliability of items on the School Physical Activity Policy Assessment (S-PAPA), an instrument designed to assess school PA policy related to physical education (PE), recess, and other opportunities. To develop items, we perused associated literature, examined existing inst...
Prediction of maximal oxygen uptake from a 3-minute walk based on gender, age, and body composition.
The purpose was to develop new maximal oxygen uptake (VO2max) prediction models using a perceptually regulated 3-minute walk test. VO2max was measured with a maximal incremental cycle test in 283 Japanese adults. A 3-minute walk test was conducted at a self-regulated intensity corresponding to ratin...
The use of pedometers for monitoring physical activity in children and adolescents: measurement considerations.
Pedometers are increasingly being used to measure physical activity in children and adolescents. This review provides an overview of common measurement issues relating to their use. Studies addressing the following measurement issues in children/adolescents (aged 3-18 years) were included: pedometer...
Self-determined to exercise? Leisure-time exercise behavior, exercise motivation, and exercise dependence in youth.
Scant research has examined the determinants of primary exercise dependence symptoms in youth. Study purposes were to examine sex differences across leisure-time exercise behavior, motivation, and primary exercise dependence symptoms in youth and the extent to which exercise behavior and motivation...
Some strategies for sustaining a walking routine: insights from experienced walkers.
These results also indicate the 3CM technique may be an effective way to explore beliefs and motivations regarding physical activity....
Motivations for adolescent participation in leisure-time physical activity: international differences.
Although there are substantial international differences in adolescent physical activity (PA), cross-country motivational differences have received limited attention, perhaps due to the lack of measures applicable internationally. Identical self-report measures assessing PA and motivations for PA we...
