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 and(More)
The present study examined links between physical activity and quality of life experienced by individuals with physical disabilities recruited from a wheelchair user's basketball tournament. The participants included 12 male and 14 female adults between the ages of 18-54 (M=31.12, SD=10.75) who all reported one or more condition(s) that impacted their daily(More)
We used the Constructive Narrative Perspective (CNP), a three-level, progressively complex reasoning schema, to examine how individuals perceive barriers to physical activity. Sedentary adults (N = 23) aged 50 years and older (M = 65.23; SD = 6.03) participated in semi-structured interviews regarding their reasons for physical inactivity. The results(More)
Dear Dr. Tomotaka Sobue (editor): Inoue and colleagues 1 published results from a cross-sectional mail survey that examined the joint associations of television viewing time and a categorical estimate of moderate to vigorous physical activity (MVPA) with overweight/obesity in older Japanese adults. 1 While it is fitting to draw conclusions regarding the(More)
The current study examined predictors of individual differences in the magnitude of practice-related improvements achieved by 87 older adults (meanage 63.52 years) over 18-weeks of cognitive practice. Cognitive inconsistency in both baseline trial-to-trial reaction times and week-to-week accuracy scores was included as predictors of practice-related gains(More)
We assessed the factor structure of a revised version of the Exercise Imagery Inventory (ELI; Giacobbi, Hausenblas, & Penfield, 2005), second-order interrelationships for cognitive and motivational forms of mental imagery, and associations with exercise behavior and barriers self-efficacy. A convenience sample of 358 (M age = 20.55 years, SD = 3.88) college(More)
