Purpose: This study investigated the effects of the menstrual cycle on running economy (RE). Method: Eleven eumenorrheic female athletes (mean age: 21.18 [plus or minus] 3.65 years, height: 170.2 [plus or minus] 6.6 cm, VO[subscript 2]max: 49.25 [plus or minus] 9.15 mL[middle dot]kg[superscript -1][middle dot]min[superscript -1], and menstrual…

Purpose: The purpose of this study was to examine the predictive relationship among physical activity, health-related fitness, and on-task classroom behavior in children using a discriminant function analysis. Method: Participants were a convenience sample of children (N = 533; M[subscript age] = 8.8 ± 1.9 years) recruited from 77 1st- through…

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar,…

Purpose: Before-school programs, one of the least studied student-related comprehensive school physical activity program (CSPAP) components, may be a promising strategy to help youth meet the physical activity (PA) guidelines. This study's purpose was to examine: (a) how much PA children accrued during a before-school running/walking club and…

Purpose: The purpose of this study was to examine region, age, and sex profiles of physical fitness in Hungarian youth. Method: A sample of 2,602 Hungarian youth aged 10 to 18 years old completed a series of physical fitness field tests: the Progressive Aerobic Cardiorespiratory Endurance Run (PACER) fitness test, body mass index (BMI), percent…

Purpose: Identification of factors that relate to physical activity behavior in children at higher risk for weight problems--namely, children with obese parents--is key to informing the development of effective interventions to promote physical activity and reduce obesity. The purpose of our study was to examine children's perceptions of parental…

Growth, maturation, and development dominate the daily lives of children and adolescents for approximately the first 2 decades of life. Growth and maturation are biological processes, while development is largely a behavioral process. The 3 processes occur simultaneously and interact. They can be influenced by physical activity and also can…

Purpose: The purpose of this study was to objectively assess levels of physical activity (PA) and sedentary behavior (SB) of Chinese city children and youth aged 9 to 17 years old using accelerometers and to examine their differences by gender, age, grade, and weight status. Method: The PA and SB of 2,163 students in 4th grade through 11th grade…

The link between physical activity and weight loss has precipitated interest in interventions to foster adherence to exercise. It has been suggested that treatment effects, when significant, should be analyzed to determine theory-based mediators. This research assessed possible mediation of changes in Physical Self-Concept, Exercise Self-Efficacy,…

In this study, I conducted focus group interviews with 21 Arab American college students (9 men, 12 women; 9 Muslims, 12 non-Muslims), who were selected for extreme manifestation of religiosity or acculturation, to explore their beliefs and attitudes toward socioecological (SE) factors that facilitated and hindered their individual physical…

One of the most critical public concerns in the United States is the rapid increase in childhood obesity, partly due to the social and environmental changes (e.g., excessive TV and computer use, pressures of standardized testing, etc.) in the past few decades, which has resulted in less physical activity in school children's daily routines.…

The purpose of this study was to establish sex-specific criterion-referenced standards for pedometer-determined physical activity related to body mass index (BMI)-defined weight status among youth. We analyzed data from 7-16-year-old boys (n = 338) and girls (n = 337) and used pedometer-assessed physical activity and anthropometric data to derive…

Despite the popularity of skateboarding worldwide, the authors believe that no previous studies have investigated the metabolic demands associated with recreational participation in the sport. Although metabolic equivalents (METs) for skateboarding were published in textbooks, the source of these values is unclear. Therefore, the rise in…

The relationship between average daily step counts and age, body mass index (BMI), self-reported physical activity (PA) level, and perceived health was determined in 85 middle-aged and older adults who wore a pedometer for 7 consecutive days. Average daily steps were significantly (p less than 0.05) correlated with BMI (r = -0.26), age (r = -0.44)…

This study sought to determine whether weight status influences the association among children's fundamental movement skills (FMS) and physical activity (PA). Two hundred forty-eight children ages 9-12 years participated. Proficiency in three object-control skills and two locomotor skills was examined. Accelerometers objectively assessed physical…
