Objective: To examine the effect of receiving daily motivational text messages on the change in college students' nutritional choices and levels of physical activity. Participants: Two hundred and one university students participated in an eight-week experimental/control group study. Methods: All participants received a brochure that contained…

Background: Affective associations have been shown to predict physical activity, but interventions designed to manipulate affective associations are limited. Purpose: To increase physical activity through manipulation of affective associations toward physical activity using the values component from Acceptance and Commitment Therapy (ACT) in…

The purpose of the study was to examine the effectiveness of "efitbuddy," a theory-based smartphone application, on young adults' BMI, physical activity, and motivation across a 4-week intervention. Participants were a convenience sample of 312 (mean age = 19.4 ± 2.3 years) college students. A quasi-experimental design with the control…

Purpose: The purpose of this study was to examine if automatic enrollment in exercise-promoting courses on a college campus, with a choice to opt out, would increase enrollment. Method: In a simulated course selection paradigm, 317 college students were randomly assigned to one of three conditions: optimal default (automatic enrollment in an…

This article presents an analytic approach to assessing the relationship between policy advocacy activities and outcomes for discrete episodes of advocacy, using a holistic array of factors that affect the relationship between advocacy and policy change. The factors pertain to not only advocacy organizational structure and strategies, but also the…

In this study, we aimed at comparing Finnish primary school students' physical activity and sedentary time during outdoor-learning and traditional school days. Outdoor learning is defined as purposeful and planned learning experiences in the outdoors . The study population consisted 20 students in grades 1-6 at one primary school. Physical…

Background: Individuals with intellectual disability (ID) have very low physical activity and low peak oxygen uptake (VO[subscript 2peak]), potentially explained by physiologically lower peak heart rates (HR[subscript peak]). Method: The present authors performed a retrospective analysis of a large data set of individuals with intellectual…

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…

Background: Authorities recommend that youth undertake at least 60 minutes of daily moderate-to-vigorous physical activity (MVPA), with young people having the opportunity to undertake at least half of this MVPA during school hours. Methods: In this study, we examined the influence of school-level socioeconomic status (SES) on children's PA,…

Background: High volumes of school-based sedentary time may impact academic achievement and executive function negatively. This study evaluated a multimodal classroom program's (POWER) effect on fifth graders' physical activity (PA) and executive function. Methods: Six 5th grade classes (3 = intervention [POW]; 3 = waitlist control [CONT]) in 2…

Purpose: The role of a structured program of exercise training on the low-risk pregnancy in Iranian women undergoing "in vitro" fertilization (IVF) based on the reduction of gestational diabetes was examined. Method: A comparative quasi-experimental clinical trial with 170 IVF-pregnant women in two intervention and control groups was…

Background: Behavioral interventions to prevent pediatric obesity have shown inconsistent results across the field. Studying what happens within the "black box" of these interventions and how differences in implementation lead to different outcomes will help researchers develop more effective interventions. Aim: To compare the…

Outdoor education programs have been shown to have a positive effect on the educational, physical and emotional development of youth. They are increasingly being used to foster a sense of community in schools and to provide students with learning opportunities related to the environment. This article describes an integrated outdoor education…

Purpose: This feasibility study compared the effects of 2 movement programs, traditional and mastery climate (i.e., the Children's Health Activity Motor Program [CHAMP]), on lesson context and children's physical activity (PA) levels. A secondary aim was to examine sex differences in PA levels in both programs. Method: Seventy-two preschoolers…

Background: TV viewing and computer game use may both limit physical activity, but only TV viewing may promote a poorer diet due to exposure to food advertising and availability of the hands for snacking. Purpose: The purpose of this study was to investigate relationships between the different screen times and type 2 diabetes markers among youth.…
