An Examination Of Finish Time Variation For Collegiate Cross Country National Championships By Gender, Kevin Riley Peters Dec 2012

An Examination Of Finish Time Variation For Collegiate Cross Country National Championships By Gender, Kevin Riley Peters

Boise State University Theses and Dissertations

In cross country, women compete over shorter distances than men with little justification for these differences. The purpose of this study was to assess gender differences for the spread of finishing times and examine the appropriateness of shorter competition distances for females. Forty-six cross country national championship data sets (nmales = 10,788; nfemales = 10,884) from the NCAA (1999-2011) and NAIA (2005-2011) were utilized for analyses. Several measures of variation were computed to assess spread of finishing times data (i.e., Coefficient of Variation [CV]; Interpercentile Ranges [IR], and Rates of Separation [RS; IR divided by the distance …

Gait modification represents a non-invasive method for reducing knee joint loading in patients with knee osteoarthritis. Previous studies have shown that a variety of gait modifications are effective in reducing the external knee adduction moment. The external knee adduction moment is often used as a surrogate measure of medial compartment force. However, a recent study showed that reductions in the external knee adduction moment do not guarantee reductions in medial compartment loads. Therefore, direct measurement of changes in knee contact force is important for determining the effectiveness of gait modifications. A previous study found that medial thrust gait and walking …


Throwing Frame For Athletes With Dissabilities, Andrew Higgins, Stefan Owechko, Gabriel (Gabe) Terrasas, Kevin Crisfield Jun 2012

Throwing Frame For Athletes With Dissabilities, Andrew Higgins, Stefan Owechko, Gabriel (Gabe) Terrasas, Kevin Crisfield

Mechanical Engineering

Team Zeus’ senior project was to design, build and test a working throwing frame system for Bridge II Sports, a nonprofit organization in North Carolina. The throwing frame is used to allow athletes and individuals with disabilities to throw shot-put, discus, and javelin using a frame to sit against. Team Zeus was specifically tasked to build a frame that is lighter weight and more transportable than products that are currently on the market. This frame also is adjustable to accommodate a wide range of athlete weights, sizes, and abilities. The final result is a 35lb aluminum frame with two different …
