Purpose: Grounded in the behavioral ecological model, and to address a lack of park space, this study looked at community members' use of public high school physical activity (PA) facilities during nonschool hours while considering the effects of seasonality. Method: Data included 3,959 observation sweeps across 19 public high school campuses over…

Adolescence is the period between childhood and adulthood and the most important stage of a human being. Adolescence is a period of stress and storm. Students cannot adjust with their new-fangled role in life. They can have Emotional, Mental, Behavioural, and Adjustment problems known as "disorders". Behavioural patterns that appear in…

Efficacious interventions to promote long-term maintenance of physical activity are not well understood. Engineers have developed methods to create dynamical system models for modeling idiographic (i.e., within-person) relationships within systems. In behavioral research, dynamical systems modeling may assist in decomposing intervention effects…

This study was designed to test the validity of a transtheoretical model's physical activity (PA) stage measure with intention and different intensities of behavior in a large population-based sample of adults living with diabetes (Type 1 diabetes, n = 697; Type 2 diabetes, n = 1,614) and examine different age groups. The overall…

The aims of this study were to: (a) compare physical activity across two seasons and, within those seasons, across school and vacation time, and (b) compare the proportion of children meeting the activity thresholds recommended by Tudor-Locke et al. (2004) at each time point. Thirty-six boys, between the ages of 8 and 10 years (M age = 8.8 years,…

Analyzes why so many adults are inactive by examining how children are introduced to physical activity, focusing on two behavioral principles that are germane to turning children on to physical activity (fun and self-worth), reviewing practices that violate these principles, and speculating about why the principles get violated.
