Physical activity (PA) estimates from the Fitbit Flex 2 were compared to those from the ActiGraph GT9X Link in 123 elementary school children. Steps and intensity-specific estimates of PA and 3-month PA change were calculated using two different ActiGraph cut-points (Evenson and Romanzini). Fitbit estimates were 35% higher for steps compared to…

Background: Physical activity (PA) improves outcomes, but disadvantaged children typically experience more sedentary behavior (SB). This study explored movement, executive function (EF) health, and academic achievement (AA) for economically disadvantaged kindergarteners. Methods: Children in 2 classrooms (n = 16; n = 7) wore wrist-based…

Objective: The aim of this study was to explore the efficacy of cooperative learning integrated into self-management support in influencing adolescents' physical activity (PA) and cardiopulmonary fitness (CRF), and to examine retention following an experimental intervention. Design: Quasi-experimental design. Setting: Elementary school setting the…

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…

To determine the effectiveness of Supplemental Nutrition Assistance Program--Education (SNAP-Ed) nutrition and physical activity programming in elementary schools, it is necessary to recruit socioeconomically similar comparison schools not receiving SNAP-Ed programming. We developed a flexible recruitment strategy to tailor our approach to each…

Despite proprietary algorithms to account for differences, output from activity trackers worn on different wrists may not be comparable because individuals vary in their reliance on each hand during free-living activities. Participants (n = 48) wore Fitbit Flex or Flex2 monitors on each wrist for three days. T tests, equivalence tests, and…

This study aims to demonstrate the effect of a transtheoretical model (TTM)-based physical activity program on the exercise behavior of adolescents using WhatsApp. The study was conducted with high school students (N = 185) in a pre-/posttest, quasi-experimental design. TTM-based text messages were sent to the intervention group (n = 95) over…

This study compared the energy expenditure (EE) levels during object projection skill performance (OPSP) as assessed by indirect calorimetry and accelerometry. Thirty-four adults (female n = 18) aged 18-30 (23.5 ± 2.5 years) performed three, 9-min sessions of kicking, over-arm throwing, and striking performed at 6-, 12-, and 30-sec intervals. EE…

Background: School is an important place for physical activity (PA); however, little is known about how homeschool students' PA levels compare with public and private school students. This study estimated the national prevalence of PA levels of homeschool students compared to public and private school students. Methods: We used the 2017 National…

Objectives: There is a need to examine the utility of objective measures of attention-deficit/hyperactivity disorder (ADHD) symptoms in children. Objective measures of ADHD symptoms, such as physical activity, may provide a more nuanced assessment of behavior that can be used to augment traditional cross-informant ratings of ADHD symptoms by…

It is known that the practice of physical activity (PA) drops off drastically in late adolescence, during the transition to adulthood, leading to a deterioration in physical fitness among post-secondary students. Given the importance of the consequences of physical inactivity, interventions aimed at the sustained adoption of sufficient PA practice…

The aim of this study is to investigate the effects of reformer pilates exercises on flexibility, heart rate and glucose levels of sedentary women for 8 weeks. 30 sedentary women between 30-36 years old were joined to the study. Participated in the research sedentary women' ages' mean was 32,20±1,78 year, lenghts' mean was 166,76±3,93 cm. It is…

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…

Objective: To examine the differences in experiences of stress, emotional well-being, and physical activity among international and domestic students. Participants: Domestic (n = 4,035) and international (n = 605) students at a large Canadian university. Methods: Responses to items on stress, emotional well-being (happiness and satisfaction with…

Introduction: Physical education (PE) can contribute to total daily physical activity (PA) among children. In consequence, the Spanish Ministry of Education, Culture and Sport has developed 16 teaching units focused on increasing PA levels during PE lessons, called "Unidades Didácticas Activas" (UDA; Active Teaching Units). Objectives:…
