High Intensity Interval Training (HIIT) is an effective strategy for improving health-related fitness in youth. With continued trends of reduced physical education activity time, disturbing youth obesity rates, and outdated fitness testing practices, HIIT training becomes a viable option to use in physical programs to increase physical health and…

Background: Schools are an important setting for health promotion because they afford children and adolescents numerous opportunities to accumulate the recommended physical activity (PA) minutes and make other health-related decisions, including healthy eating. Unfortunately, there is little evidence of coordinated school-based health…

All Latin-American countries are affected by the lack of physical activity and its consequences on youth. Chile's population has shown troublingly low levels of moderate-to-vigorous physical activity. This is the first study using objectively measured physical activity levels in Chilean adolescents. The objectives were to compare the compliance…

Adolescents often practice unhealthy behaviors to lose weight or keep from gaining weight. Centers for Disease Control and Prevention has conducted biennial Youth Risk Behavior Survey (YRBS) of various health risk behaviors since 1991 using U.S. representative samples of high school students and is therefore best for us to identify risk/preventive…

Adolescents with overweight and obesity are at risk for future health problems. The purpose of this study was to examine the feasibility and initial efficacy of a weight management intervention to help adolescents develop healthy nutrition and physical activity behaviors and improve their anthropometrics. This study used a single-group repeated…

Purpose: In youth, cross-sectional studies reported age differences in balance performance that were in favor of adolescents. Thus, trainability of balance performance might be different in children compared to adolescents. The purpose of this study was therefore to compare the effects of balance training (BT) on balance performance between…

Background: This study examined the sustainability of New Moves, a school-based program aimed at decreasing weight-related problems in adolescent girls. The National Cancer Institute recognizes New Moves as a research-tested intervention program that produced positive behavioral and psychosocial outcomes. Methods: Ten schools participated in the…

This pilot project aimed to demonstrate the efficacy and feasibility of an innovative physical education programme, referred to as a health club (HC) approach, in a high school setting. We measured adolescent girls' moderate to vigorous physical activity (MVPA), components of health-related physical fitness, and perceptions about themselves and…

Schools are positioned to play a key role in nurturing students with knowledge and behaviours associated with healthful living. Our study examined the effects of an intervention on energy balance (EB) knowledge. Twelve 6th and 7th grade classrooms (n = 140) were assigned to receive either two standardised lessons on EB or a combined intervention…

Weight-Based Victimization is a frequent experience for adolescents who are overweight or obese, and is associated with numerous psychosocial and physical consequences for those who are targets of victimization. Assessing targets' preferences for different types of support and intervention has been absent in the context of weight-based…

The purpose of this article is to bring attention to the 10 most pressing questions relevant to musculoskeletal physical fitness testing in children and adolescents. The goal is to stimulate research to answer these questions. The most pressing needs include establishing definitive links between valid, reliable, and feasible field test measures of…

The Carol M. White Physical Education Program (PEP) provides grants to districts and community-based organizations (CBOs) to initiate, expand, and improve physical education for students in kindergarten through grade 12. In 2010, the U.S. Department of Education issued new regulations for PEP that included the following: (1) requiring grantees to…

American youths are becoming increasingly less physically active and have poor nutrition habits. Nationwide, less than one third of students reported achieving the recommended level of physical activity (one hour of exercise per day). In addition, most youths consume less than the recommended daily amounts of vegetables, fruits, and whole grains.…

Background: Detailed knowledge about physical activity energy expenditure (PAEE) can guide the development of school interventions aimed at reducing overweight in adolescents. However, relevant components of PAEE have never been objectively quantified in this population. This study investigated the contribution of active transport to and from…

Background: Relatively little is known about how perceived weight controllability influences important psychological health factors among adolescents. Thus, the purpose of this study is to explore adolescents' weight controllability beliefs and how those beliefs influence weight-related attitudes and behaviors. Methods: Adolescents (N = 369, mean…
