Management Of Youth Sport-Related Concussion By Urban And Rural Practitioners: A Pilot Study, Brett R. Fox

All NMU Master's Theses

Sport-related concussions (SRC) occur at alarming rates among high school athletes (ages 13-18), which made the Center for Disease Control and Prevention and other agencies classify it as an “epidemic”. If improperly managed, physical, mental, and emotional consequences can occur for SRC patients. Due to these consequences all 50 states in the US have passed legislation requiring medical release from a practitioner before a student-athlete can return to athletics following an SRC, yet there is no universally accepted consensus on how to medically manage this common injury. A 22-item, validated survey was distributed to Michigan practitioners who sign off on …

Investigating Force-Velocity Profile Alterations And Methodology After Traditional Resistance Training, Joseph D'Amato

Electronic Theses and Dissertations

The purposes of this dissertation were to examine the agreement the agreement between double integration using the trapezoidal method and measurements for push-off distance to create force-velocity profiles, examine the change in push-off distance between loading conditions when force-velocity profiling, and to observe the alterations in mechanical outputs of force-velocity profiles after 15-weeks of off-season training. The major findings are as followed. Using double integration with the trapezoidal method may be a reliable way to estimate push-off distance, despite a small systematic bias. This bias should have negligible effects on push-off distance and therefore not alter or effect calculations in …

Rainbow Perfect And Near-Perfect Matchings In Complete Graphs With Edges Colored By Circular Distance, Shuhei Saitoh, Naoki Matsumoto, Wei Wu

Theory & Applications of Graphs

Given an edge-colored complete graph K_n on n vertices, a perfect (respectively, near-perfect) matching M in K_n with an even (respectively, odd) number of vertices is rainbow if all edges have distinct colors. In this paper, we consider an edge coloring of K_n by circular distance, and we denote the resulting complete graph by K^●_n. We show that when K^●_n has an even number of vertices, it contains a rainbow perfect matching if and only if n=8k or n=8k+2, where k is a nonnegative integer. In the case of an odd …
