Effects Of Expected Service Life Exposures On The Functional Properties And Impact Performance Of An American Football Helmet Outer Shell Material, David E. Krzeminski
Effects Of Expected Service Life Exposures On The Functional Properties And Impact Performance Of An American Football Helmet Outer Shell Material, David E. Krzeminski
Dissertations
The purpose of this dissertation is to gain a greater scientific understanding of the changes in functional material properties and impact performance of an American football helmet outer shell material under expected service life exposures. The research goals are to (i) quantify chemical, physical, thermal, and mechanical degradation of an American football outer shell material under expected environmental conditions and (ii) develop a linear drop test impact protocol to employ expected on-field impact conditions to American football helmet components and a plaque-foam (i.e., shell-liner) surrogate. Overall, a step-wise progression of analysis was demonstrated to concurrently quantify and understand changes in …
Coaching And Concussions: Prevention, Education, And Perspective, Colby J. Felts
Coaching And Concussions: Prevention, Education, And Perspective, Colby J. Felts
Honors Thesis
The large participation of players and coaches in football has made it one of the most popular sports in America. Concussions have specifically gained national attention in football due to frequent, high impact collisions. A concussion injury poses a unique threat in high school football because of the developing adolescent brain and high participation numbers. Additionally, lack of medical personnel to diagnose concussions at the high school level imposes a legal duty on the coaches. The thesis develops a recommended plan of action for directors of Iowa high school football to assist in preserving the future of the sport. A …
The Impact Of Educational Materials On Collegiate Student-Athletes’ Knowledge Of Sports Related Concussions, Ryan Johnson
The Impact Of Educational Materials On Collegiate Student-Athletes’ Knowledge Of Sports Related Concussions, Ryan Johnson
Graduate Theses
The purpose of this study was to investigate the effectiveness of three different types of concussion education materials for collegiate athletes and to evaluate knowledge transfer. Three different types of educational materials were used to educate the athlete. The athlete completed a pretest, completed an educational module, and then completed a posttest. Two weeks later the athlete completed a retention test. A total of 51 subjects participated in the study. The subjects were evaluated on a pretest, posttest, and retention test. Data were analyzed based on an independent t-test to compare pretest scores between athletes who have been previously concussed …
Evaluation Of Linear And Nonlinear Postural Stability Measurements Following Concussion, Kelsey Evans
Evaluation Of Linear And Nonlinear Postural Stability Measurements Following Concussion, Kelsey Evans
Electronic Theses and Dissertations
Sport related concussions affect nearly 1.6 to 3.8 million athletes annually in the United States. A large number of these athletes suffer from postural instability following concussion. Postural control assessment has become a recommended tool to determine readiness to return to play. Measurement of postural control through the use of center of pressure (CoP) variables may provide a sensitive evaluation following concussion and throughout recovery. Purpose: To evaluate a unipedal and bipedal quiet stance protocol consisting of linear and nonlinear CoP measurements with varying durations in a concussed population throughout recovery. Methods: Thirteen NCAA Division I Collegiate Football players (age: …
