Black, Nate E.; Vehrs, Pat R.; Fellingham, Gilbert W.; George, James D.; Hager, Ron – Research Quarterly for Exercise and Sport, 2016
Purpose: The purpose of this study was to evaluate the use of a treadmill walk-jog-run exercise test previously validated in adults and physical activity questionnaire data to estimate maximum oxygen consumption (VO[subscript 2]max) in boys (n = 62) and girls (n = 66) aged 12 to 17 years old. Methods: Data were collected from Physical Activity…

Sun, Bo; Liu, Yu; Li, Jing Xian; Li, Haipeng; Chen, Peijie – Research Quarterly for Exercise and Sport, 2013
Purpose: This study set out to examine the relationship between step frequency and velocity to develop a step frequency-based equation to predict Chinese youth's energy expenditure (EE) during walking and running. Method: A total of 173 boys and girls aged 11 to 18 years old participated in this study. The participants walked and ran on a…

Zhu, Zheng; Chen, Peijie; Zhuang, Jie – Research Quarterly for Exercise and Sport, 2013
Purpose: The purpose of this study was to develop and cross-validate an equation based on ActiGraph accelerometer GT3X output to predict children and youth's energy expenditure (EE) of physical activity (PA). Method: Participants were 367 Chinese children and youth (179 boys and 188 girls, aged 9 to 17 years old) who wore 1 ActiGraph GT3X…

Martin, Jeffrey J.; McCaughtry, Nate; Flory, Sara; Murphy, Anne; Wisdom, Kimberlydawn – Research Quarterly for Exercise and Sport, 2011
Few researchers have used social cognitive theory and environment-based constructs to predict physical activity (PA) and fitness in underserved middle-school children. Hence, we evaluated social cognitive variables and perceptions of the school environment to predict PA and fitness in middle school children (N = 506, ages 10-14 years). Using…

Jeong, Mihye; Block, Martin E. – Research Quarterly for Exercise and Sport, 2011
The Theory of Planned Behavior (TpB) measures the effect that individuals' behavioral belief, normative belief, and control beliefs have on their intentions to perform a specific behavior. The purpose of this study was to examine: (a) whether the TpB could predict physical educators' intentions and (b) whether physical educators' intentions and…

Michaelides, Marcos A.; Parpa, Koulla M.; Thompson, Jerald; Brown, Barry – Research Quarterly for Exercise and Sport, 2008
The purpose of this project was to identify the relationships between various fitness parameters such as upper body muscular endurance, upper and lower body strength, flexibility, body composition and performance on an ability test (AT) that included simulated firefighting tasks. A second intent was to create a regression model that would predict…
