Background: Most youth in the United States do not meet the recommended 60 minutes of daily physical activity (PA). The school environment offers an opportunity to engage students in PA. The purpose of this study was to evaluate the impact of a comprehensive school-based physical activity program on student PA across student-level and school-level…

Purpose: A comprehensive school physical activity program (CSPAP) is designed to help school-aged youth meet physical activity guidelines as well as develop the knowledge, skills, and dispositions that foster meaningful lifelong physical activity participation. In this study, we employed a "diffusion of innovations theory" perspective to…

Purpose: Leisure-time physical activity (LTPA) has always been very important for the maintenance and improvement of body composition. Thus, the aim of this study was to examine if the frequency and volume of LTPA (F-LTPA and V-LTPA) were related to indices of body composition in police officers. Method: A physical activity questionnaire was used…

The aim of the present study was to assess the level of self-perception, self-esteem, physical activity and sedentary behavior of primary school children between 10 and 12 years old in the city of Komotini (Rodopi East Greece, North), to investigate the correlation between the above parameters and to detect possible differentiation on each factor…

Children with disabilities tend to participate in fewer physical activities than typically developing children. To promote participation in physical activities for children with disabilities, it is important to understand (a) parents' experiences and roles in supporting their children's physical activities and (b) factors that might influence…

Background: The COVID-19 pandemic affected health and well-being worldwide, but little is known about how the pandemic specifically impacted families with young children. Evidence suggests a relationship between well-being and health behaviors (diet, physical activity) and that preexisting health disparities were exacerbated during the pandemic.…

We provide an overview of a recently published, edited book in a rapidly emerging field of research, policy, and practice for physical activity: "Sedentary Behavior and Health". In this commentary, we highlight the broad perspectives provided in the 27 chapters of "Sedentary Behavior and Health" and suggest a research strategy…

Adverse life events and trauma have the potential to devastate college students' lives across all domains of well-being, including physical, emotional, intellectual, spiritual, and social. Thriving despite these challenges requires academic resilience. Physical activity is one well-known strategy to support increased resilience. No research has…

The purpose of this study was to describe the accelerometry-based characteristics of overall sedentary behavior (SB) and sitting among adults under free-living conditions. Thirty-six (mean age 47.6 years) volunteers carried a waist-worn accelerometer for =4 days with data =600 min/d during 14 consecutive days. A machine learning (ML) based method…

Purpose: The aim of this study was to compare the widely used accelerometer activity cut-points derived from the absolute moderate intensity recommendation (3-6 METs), with relative intensity cut-points according to maximal cardiorespiratory fitness (46%-63% VO[subscript 2max]) and to individual lactate thresholds (LT1 and LT2) in postmenopausal…

Purpose: The purpose of this study was to investigate the differences in metabolic responses between the track and the treadmill (1% inclination) running. The latter is recommended for use in laboratory settings to mimic outdoor running. Method: Seventeen male endurance athletes (mean 25.8, s = 3.8 years) performed 4-min running bouts on an indoor…

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…

Purpose: To evaluate whether excess body mass influences the heart rate variability (HRV) indexes at rest, and to correlate adiposity indicators and the aerobic fitness with cardiac autonomic variables in metabolically healthy young adults. Method: In all, 41 untrained males (M[subscript age] = 21.80, SD = 2.14 years), 14 normal weight…

This study examined the effect of a physical activity program on student activity during recess and on disruptive classroom behavior. The program was implemented during recess for 5 weeks in a rural elementary school. Prior to and during the program, teachers recorded observations of sedentary students during recess and of disruptive classroom…

Gamification is an increasingly popular form of health intervention but its efficacy remains elusive due to a lack of clarity in its conceptualization and operationalization. This study aimed to isolate and determine the direct causal effect of one of the most popular game elements used in gamified interventions, the points-based reward system, on…
