Shock Attenuation And Impact Characteristics For Children Running At Different Stride Lengths, Kunal Bhanot
UNLV Retrospective Theses & Dissertations
The purpose of this study was to quantify shock attenuation (SA) and impact characteristics for children (boys and girls) running with different stride lengths (SL). Ten physically active children (10.7+/-1.1 yrs; 40+10.3 kg; 145.2+/-7.3 cm) ran at a constant speed of 3m/s +/- 5% range to complete three stride length conditions: Preferred stride length (PSL), -15%PSL and +15%PSL. During PSL, participants were given no instructions regarding stride length. During -15%PSL and +15%PSL, participants were required to strike markers placed on the floor that resulted in stride length of -15% and +15% of PSL. Ground reaction forces were recorded (1008 Hz) …

Effects Of Traumatic Brain Injury On The Attention System Of Children, Brandon Steven Park
UNLV Retrospective Theses & Dissertations
Mirsky et al. (1991) proposed a four factor structure of attention (Shift, Focus, Encode, and Sustain) that found strong support across various clinical and non-clinical samples (see Mirsky & Duncan, 2004). Using a differing theoretical model Spikman et al. (1999) found that traumatic brain injury (TBI) changed the measured structure of attention. The purpose of the study was to assess if the structure of attention maintained in children who had sustained a TBI using the Mirsky model of attention. For the study 151 children between the ages of 8.9 and 18.4 years (mean 12.9, sd 2.6) suffering from traumatic brain …
