UNLV Theses, Dissertations, Professional Papers, and Capstones
This study examined the effects that cell phone use has on gait and situation awareness. Subjects (n=18; 24.67±3.60 yrs) completed three five-minute treadmill walking conditions (self-selected speed): (1) CONTROL (walking only), (2) TALK (walking and talking), and (3) TEXT (walking and texting). The number of detected lights presented in the visual field was recorded, as were kinematic data of the feet. Using a one-way repeated measure ANOVA it was determined light detection (F (2,17) =39.777, p<0.001) and TCmin (F(2,17) =8.574, p=0.001) were different between conditions. Specifically, light detection decreased during TEXT (2.6±2.2 lights) versus TALK (5.8±0.05 lights, p<0.001) or CONTROL (5.9±0.05 lights, p<0.001); TCmin decreased …

An Examination Of Body Composition Measurement Methods In Children, Robert Kaplan
UNLV Theses, Dissertations, Professional Papers, and Capstones
Introduction . Body-composition methods include underwater weighing (UWW), skinfold thickness (SKF), bioelectrical impedance (BIA), and the BOD POD. Although these techniques are used routinely, each has its inherent limitations, especially in children. Purpose . The purpose of this study was to examine the various methods of body composition in children. Methods . The body composition of 7 boys between the ages of 12-14 (13.1 +/- 1.1 years) was determined using the BOD POD, UWW, SKF, and BIA. Results . Percent body fat estimated from the BOD POD (21.9 +/- 7.8%BF) was not significantly different than the estimated percent fat from …
Ground Reaction Forces For Children Running In Different Shoes, Dana Forrest
Ground Reaction Forces For Children Running In Different Shoes, Dana Forrest
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to determine whether certain ground reaction force parameters such as impact force (F1), second maximum force (F2), loading rate, stance time and average vertical ground reaction force (Fzavg) differ when 11-13 year old children run in a neutral shoe (Nike Air Pegasus+ 25) that is either a child or adult style.
Shoes were impact tested in an impact test instrument to determine any performance differences between the two shoes. Next, 10 healthy female subjects aged 12.03 ± 1.14 years with a height of 154.6 ± 4.90 cm and a mass of 46.18 ± 14.33 …
