Background. Monitoring food intake and physical activity (PA) using tracking applications may support behavior change. However, few longitudinal studies identify the characteristics of young adults who track their behavior, findings that could be useful in designing tracking-related interventions. Our objective was to identify predictors of…

Despite strong evidence in favor of physical activity (PA), adults with autism spectrum disorder (ASD) are not meeting established PA guidelines to engage in at least 150 min of moderate to vigorous PA per week. Barriers to daily PA engagement include limited access to health services, transportation, and reduced self-determined motivation.…

Objective: This study investigates the relationship between fitness tracker users' communication of exercise information and their exercise intentions and behaviors among college students. Participants: Data were collected from 186 undergraduate students. Methods: A quantitative online survey was conducted. Descriptive norm (perceptions of…

In spite of the fact that physical activity is inevitable in sustaining health, there are more people in the world who do not take it into account than who do. A growing number of young adults have been using wearable activity trackers, particularly step counts, to keep an eye on their health in the past few years. In an online survey university…

The purpose of this study was to evaluate the influences of a structured after-school program on student physical activity for third- through fifth-grade students at five schools in southern Colorado. The study utilized a pretest-posttest intervention design in which six elementary schools in a low socioeconomic status school district in southern…

Differences between interactive active video games (AVGs) and non-interactive AVGs on sedentary behavior, light physical activity, and moderate-to-vigorous physical activity has never been compared. Therefore, the purpose of this study to compare differences between two AVGs modalities on sedentary behavior, light physical activity, and…

Background: Research has elucidated some harmful aspects of fitness wearable devices including their role in exacerbating disordered eating and exercise behaviors in young adults. Purpose: The purpose of this study was to examine 1) if use of wearables was associated with exercise dependence and 2) prevalence of compensatory behaviors (CB) in…

We compared time spent in moderate and vigorous physical activity (MVPA), type, and frequency of participation in physical activities between adolescents with ASD (n = 35) and typically developing (TD) adolescents (n = 60). Accelerometers measured MVPA and participants were interviewed about engagement in physical activities. Adolescents with ASD…

The purpose of this study was to describe fifth grade students' physical activity (PA) while playing a dance-based video game, Just Dance 4, and to examine the influence direct feedback about their performance had on their level of activity. Twenty-seven students in the 5th grade from an elementary school in the Rocky Mountain West participated.…

Objective: To explore young people's perceptions of pedometers and investigate behaviours exhibited while being monitored. Design: Qualitative design using six focus groups with participants (mean age 14.7 years). Setting: Study participants (n = 24) were randomly selected from a previous study of 123 young people aged 14-15 years from three…

Adults with autism spectrum disorder and intellectual disability often do not engage in healthy levels of physical activity despite its many benefits. We conducted a randomized control trial to evaluate the effectiveness and feasibility of the Step It Up program, which used supported self-management strategies, on daily step counts, health…

Digital technologies are now considered important in shaping young people's engagement in and with health and physical activity. Recent discussions show that the use of digital technologies to track health and fitness may over-emphasize the linear understanding of the body and health generally underpinned by Western health ideologies such as…

The primary aim of this study was to determine the effects of classroom-based exercise breaks (Energizers; Mahar, Kenny, Shields, Scales, & Collins, 2006) on students' physical activity levels during the school day. A multiple baseline design across first grade (N = 3) and second grade (N = 3) classrooms was used to examine the effects of the…

Regular physical activity participation can have a positive impact on overall health. However, school-aged individuals with visual impairments tend to be less physically active than their peers without disabilities (Haegele & Porretta, 2015). Fortunately, preliminary intervention research suggests that physical activity levels of those with…

This study examined (a) the validity of two accelerometers (ActiGraph GT3X [ActiGraph LLC, Pensacola, FL, USA] and activPAL [PAL Technologies Ltd., Glasgow, Scotland]) for the assessment of sedentary behavior; and (b) the variations in assessment accuracy by setting minimum sedentary bout durations against a proxy for direct observation using an…
