Checking In, Concussions Out: Body Checking As A Way Of Reducing Concussion Rates, Griffin Germond

All Student Scholarship

Women’s college ice hockey, according to a study released by the NCAA in 2014, has the highest rate of self-reported concussions of any collegiate sport, men’s or women’s. This is shocking, considering the fact that body checking is illegal in women's ice hockey. Why are these rates so high when there isn't body checking? This investigative research project aims to realize a novel approach at reducing concussion rates in women’s ice hockey by doing the unexpected: Allowing body checking. If body checking were allowed, this would reduce the rate of concussions if it were to be implemented and taught under …

Elastic resistance is a common training method used to gain strength. Currently, progression with elastic resistance is based on the perceived exertion of the exercise or completion of targeted repetitions; exact resistance is typically unknown. This study's objective is to determine if knowledge of load during elastic resistance exercise will increase strength gains during exercises. Participants were randomized into two strength training groups, elastic resistance only and elastic resistance using a load cell (LC) that displays force during exercise. The LC group used a Smart Handle (Patterson Medical Supply, Chicago, IL) to complete all exercises. Each participant completed the same …

The Effect Of Remote Ischemic Preconditioning On Exercise Hyperemia In Multiple Sclerosis, Jane E. Rosmarin

Honors Theses

Remote ischemic preconditioning (RIPC) is a non-invasive technique in which blood flow is cut off to a limb for a short period of time which produces a protective effect throughout the whole body to subsequent low oxygen conditions. One of the prominent cardiovascular limitations to exercise in individuals with multiple sclerosis (MS) is fatigue, which may stem from the decreased delivery of oxygen to muscle tissue during exercise. The purpose of this study was to test the hypothesis that RIPC would increase forearm blood flow (FBF) and utilization of oxygen at the level of the muscle tissue in individuals with …

Leaving A Legacy: Empowering Students To Give Back, Eric Schutter

Honors Theses

Most college universities struggle to convince alumni to give back to their former institutions. Currently, only 19.9% of college alumni give back to their former colleges (Alumni Factor, 2018). Despite the amount of time and energy that schools invest in their students, many of the students are not making any sort of commitment in return. However, there is a solution. If college programs found ways to create avenues for students, both current and former, to give back outside of just university general funds, they could see an increase in student giving from both parties. While there is a notion that …

Commentary: The Use Of Case-Based Learning And Concept Mapping To Teach Students Clinical Reasoning, Jeremy R. Hawkins, Michael Reeder, Michael Olson, Amy Bronson

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Introduction: Teaching students as inexperienced clinicians the process of evaluating athletic injuries and medical conditions is often challenging. Utilizing case-based learning and concept mapping as educational tools can facilitate growth in the clinical and diagnostic decision making process. Discussion: Experienced clinicians regularly employ case pattern recognition and hypothetico-deductive reasoning in clinical settings. Each type of reasoning is prone to anchoring and confirmation bias, devaluing relevant information, and framing effect if not utilized correctly. Classroom instructors and preceptors can use case-based learning and concept mapping to help students as inexperienced clinicians organize their thinking and more effectively apply their …

Methods:

Using a parallel experimental design, participants were randomly assigned to either a SWM (n=52) or non-exercising control group (n=48) for 20 weeks. …

Estimating Variations In Metabolic Cost Within The Stride Cycle During Level And Uphill Walking, Arash Mohammadzadeh Gonabadi

UNO Student Research and Creative Activity Fair

Indirect calorimetry provides the average cost of a stride cycle and prevents from identifying which part of the gait cycle causes increased metabolic cost in patients, however, recent simulation methods allow estimating the time profile of metabolic cost within the stride cycle. In this study, we compare the estimations of the time profile of the metabolic cost of two simulation methods for level and uphill walking. We used kinematic, kinetic and electromyography data from level and uphill walking (one participant) to estimate the time profiles of metabolic cost using the muscle-level metabolic model of Umberger using electromyography and kinematic data …

The Energy Paradox Of The Ankle-Foot Complex During Human Walking, Nikolaos Papachatzis, Kota Takahashi

UNO Student Research and Creative Activity Fair

Flexor hallucis longus (FHL) is a multiarticular muscle that possesses the potential to alter foot’s functional and mechanical behavior, since it performs multiple significant functions during walking (e.g supports the medial longitudinal arch of the foot).The purpose of this study was to determine if the functional changes of the FHL are associated with the foot’s adaptations to the mechanical demands of walking. Backward walking is an experimental method capable of altering how the forces propagate underneath the foot and disrupting the mechanical function of the FHL muscle. We hypothesized that: (1) the muscle activity of the FHL will increase during …
