Between 1980 and 2000, obesity rates in the United States have doubled for adults and tripled for children (Centers for Disease Control [CDC], 2015). In addition, Texas, the second largest state, ranks 10th for the highest percentage of obesity among youth age 10-17 (CDC, 2015). Nationally, the United States falls behind other countries in high…

Meta-analyses combine the results of multiple studies of a common question. Approaches based on effect size estimates from each study are generally regarded as the most informative. However, these methods can only be used if comparable effect sizes can be computed from each study, and this may not be the case due to variation in how the studies…

The purpose of the current study was to investigate how combinations of different epoch durations and cut-points affect the estimations of sedentary time and physical activity in adolescents. Accelerometer data from 101 adolescents were derived and 30 combinations were used to estimate sedentary time, light, moderate, vigorous, and combined…

Background: We examined the impact of the Fuel Up to Play 60 (FUTP60) program on children's body mass index (BMI) and aerobic capacity (AC). Methods: Participation in the FUTP60 and both BMI and AC profiles were collected through the NFL PLAY 60 FitnessGram Partnership Project involving over 100 schools from 22 US states. We specifically examined…

The counter-movement jump is a consequence of maximal force, rate of force developed, and neuromuscular coordination. Thus, the counter-movement jump has been used to monitor various training adaptations. However, the smallest detectable difference of counter-movement jump metrics has yet to be established. The objective of the present study was…

Purpose: The purpose of this study was to analyze tracking and stability of motor coordination in children from age 6 years to ages 9 and 13 years. Method: Data were from the Copenhagen School Child Intervention Study. Motor coordination (MC) was measured using the körperkoordinationstest für Kinder (KTK) test. The crude performance score on every…

Background and Objective: Increased emphasis on academic outcomes has reduced the amount of time spent in physical education and other school physical activity opportunities in many schools in the USA. However, physical fitness is a positive predictor of academic performance on standardised tests, and students who perform better on fitness…

The aim of this study was to investigate the effect of plyometric training on repeated sprint ability in amateur soccer players. Twenty amateur soccer players participated in this study as the subject. The subjects were randomly assigned to plyometric training group (n=10, age: 19.7[plus or minus]2.26 years) and control group (n=10, age: 18.8[plus…

The present study examined associations between effortful control, a trait marker of self-regulation, adaptive hypothalamic-pituitary-adrenal (HPA) system functioning (as reflected by the cortisol awakening response [CAR]), and concurrent and longitudinal depressive problems, in a sample of preadolescent Latino youth (N = 119, mean age = 11.53…

Guided by the biopsychosocial model, we examined (a) the prevalence of weight control behaviors (WCBs; i.e., trying to stay the same weight, lose weight, gain weight, or do nothing about weight) among early adolescent boys by race/ethnicity and grade level, and (b) how the boys' perceptions of sociocultural pressures (from parents, peers, and…

The decline in physical activity (PA) from youth to young adulthood is evident, though limited research has addressed whether specific factors of K-12 physical education (PE) have any influence on outcomes during college years. This study examined the relationship between college students' physical fitness and PA behavior and their high school PE…

We aimed to assess the impact of Project Spraoi: a school-based physical activity (PA) and nutrition intervention that reached 473 primary school children and 43 school staff in Cork (Ireland). Four primary schools (2 intervention, 2 control) with similar characteristics participated and for 2 school years, intervention schools were assigned an…

Objective: This study investigated relative associations between physical activity and selected predisposing, reinforcing and enabling factors among 9- to 10-year-old children from socially disadvantaged communities and examined the extent to which these associations varied by sex. Design: Cross-sectional design. Setting: Ten public primary…

Background: Many studies document associations between low health literacy (HL) and poor health behaviors and outcomes. Yet, HL is understudied among adolescents, particularly from underserved, rural communities. We targeted rural adolescents in this cross-sectional study and explored relationships between HL and (1) energy-balance-related health…

Background: Most pediatric elevated blood pressure (BP) remains undiagnosed. The American Academy of Pediatrics states "there is limited evidence to support school-based measurement of children's BP." We explored the utility school-based BP screening. Methods: A cross-sectional sample of 4096 students ages 6 to 17 from Title 1 Miami-Dade…
