Designing A Mechanical Linkage Capable Of Decreasing Force Transfer From The Facemask To The Protective Helmet When Loading Occurs, Levi Hansen Dec 2014

Designing A Mechanical Linkage Capable Of Decreasing Force Transfer From The Facemask To The Protective Helmet When Loading Occurs, Levi Hansen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Sports that involve extensive personal contact have a high incidence of injury. The introduction of regulations mandating the use of personal protective equipment in these sports is the most common injury control strategy (Marshall et al., 2002). Negligible attention has been paid to the mechanical linkage between the facemask and helmet as a means of reducing force transfer from the facemask, through the helmet, and to the head and or neck of the athlete.

Methods

A novel prototype mechanical linkage of reasonable simplicity that provides 360° of freedom in motion capable of decreasing force transfer from the facemask to ...

Athletic Training Collection

This article discusses the principles and practices that guide psychological intervention with injury, and encourages a psychological approach to injury for clinicians. Part 1 reviews the research literature, and serves as a foundation for the review of clinical practices in part 2. Examination of the research literature highlights 4 areas: (1) psychological factors influencing rehabilitation, (2) social factors affecting rehabilitation, (3) performance concerns among returning athletes, and (4) tools/inventories for assessing psychological readiness to return. A synopsis of an injury intervention plan is provided, and the influence of pain and fear in the rehabilitation process is described.


Sports Related Traumatic Brain Injuries, Ky Parrott Oct 2014

Sports Related Traumatic Brain Injuries, Ky Parrott

Nursing Student Class Projects (Formerly MSN)

Traumatic Brain Injuries (TBI) are the leading cause of long-term disability and injury death in the United States of America (Dash, Oh, Santiago, & Wade, 2012, p. 108). It is estimated that approximately 75% of all TBI’s are sports related. Recently, sports related TBI’s have received increased awareness due to the $765 million settlement between 18,000 retired football players who suffer from long-term concussive injuries and the National Football Association (NFL) (Mason, 2013, p. 267). Education regarding the pathophysiology of TBI’s is beneficial to understanding what changes the brain is enduring and why it is important to ...

Blood-Based Biomarkers For Traumatic Brain Injury: Evaluation Of Research Approaches, Available Methods And Potential Utility From The Clinician And Clinical Laboratory Perspectives, Frederick G. Strathmann, Stefanie Podlog (Nee Schulte), Kyle Goerl, David J. Petron

Athletic Training Collection

Blood-based biomarkers for traumatic brain injury (TBI) have been investigated and proposed for decades, yet the current clinical assessment of TBI is largely based on clinical symptoms that can vary widely amongst patients, and have significant overlap with unrelated disease states. A careful review of current treatment guidelines for TBI further highlights the potential utility of a blood-based TBI biomarker panel in augmenting clinical decision making. Numerous expert reviews on blood-based TBI biomarkers have been published but a close look at the methods used and the astonishing paucity of validation and quality control data has not been undertaken from the ...


Effects Of Playing Surface And Shoe Type Of Acl Tears In Soccer Players, Melissa Mansfield Jun 2014

Effects Of Playing Surface And Shoe Type Of Acl Tears In Soccer Players, Melissa Mansfield

Honors Theses

Anterior Cruciate Ligament injuries have become more common in athletes over the past decade which is believed to result from playing on more artificial turf surfaces. This study tested the playing surface theory by building upon a previous study conducted with Albany Medical Center which tested surface samples using an axial-torsion load frame located at Union College. The motion that causes most ACL noncontact injuries is replicated by the load frame which pushes and rotates a shoe against the playing surface and measures the torque it experiences. The foot position, normal load, degree of rotation and rate of rotation were ...


Refeeding Syndrome In A Young Girl With Anorexia Nervosa., Om Parkash, Adil Ayub, Shahab Abid May 2014

Refeeding Syndrome In A Young Girl With Anorexia Nervosa., Om Parkash, Adil Ayub, Shahab Abid

Department of Medicine

We report the case of a 20-year-old anorexic girl (BMI=12.9), who was misdiagnosed the first time and developed severe electrolyte imbalances due to lack of awareness about refeeding syndrome. Few cases of RS have been reported in literature and protocols have been suggested for prevention and management of this syndrome, including the awareness of circumstances in which it is most likely to develop, refeeding slowly and building-up micronutrient content over several days. Improved awareness and understanding of refeeding syndrome along with a well-coordinated plan are vital in delivering safe and effective nutritional rehabilitation. We suggest a slow and ...


Combustion, Respiration And Intermittent Exercise: A Theoretical Perspective On Oxygen Uptake And Energy Expenditure, Christopher B. Scott Ph.D. Mar 2014

Combustion, Respiration And Intermittent Exercise: A Theoretical Perspective On Oxygen Uptake And Energy Expenditure, Christopher B. Scott Ph.D.

Exercise, Health and Sport Science

While no doubt thought about for thousands of years, it was Antoine Lavoisier in the late 18th century who is largely credited with the first “modern” investigations of biological energy exchanges. From Lavoisier’s work with combustion and respiration a scientific trend emerges that extends to the present day: the world gains a credible working hypothesis but validity goes missing, often for some time, until later confirmed using proper measures. This theme is applied to glucose/glycogen metabolism where energy exchanges are depicted as conversion from one form to another and, transfer from one place to another made by both ...

Faculty of Health Sciences Publications

Protecting the health of the athlete is a goal of the International Olympic Committee (IOC). The IOC convened an expert panel to update the 2005 IOC Consensus Statement on the Female Athlete Triad. This Consensus Statement replaces the previous and provides guidelines to guide risk assessment, treatment and return-to-play decisions. The IOC expert working group introduces a broader, more comprehensive term for the condition previously known as ‘Female Athlete Triad’. The term ‘Relative Energy Deficiency in Sport’ (RED-S), points to the complexity involved and the fact that male athletes are also affected. The syndrome of RED-S refers to impaired physiological ...

Results found that individual tracks as well as the two major ownership groups highly agreed about issues concerning the use of social media to increase sales and to develop fan ...


The Relationship Of Force Production Asymmetry And Performance In Athletes Of Different Strength Levels, Christopher A. Bailey, Caleb D. Bazyler, Chieh-Ying Chiang, Kimitake Sato, Michael H. Stone Jan 2014

The Relationship Of Force Production Asymmetry And Performance In Athletes Of Different Strength Levels, Christopher A. Bailey, Caleb D. Bazyler, Chieh-Ying Chiang, Kimitake Sato, Michael H. Stone

ETSU Faculty Works

The purpose of this study was to evaluate the relationship between force production asymmetry and performance of athletes with differing strength levels in males and females. Collegiate athletes (n=129) from various sports were ranked according to isometric mid-thigh pull peak force and the top (‘strong’) and bottom (‘weak’) 25% were used for analysis. Symmetry index (SI) scores were calculated and correlated with their respective force-time characteristics using bivariate correlations. For the weaker males, several negative moderate correlations were observed; however, no statistically significant correlations were observed for the females in either group. These findings indicate that force production asymmetry ...
