A secondary aim of this research was to determine whether quadriceps strength, voluntary activation, and/or corticomotor excitability assessed in patients prior to ACLr and/or at three months after surgery, is predictive of lower extremity postural control and/or self-reported function at six …

Prospective Assessment Of Return To Pre-Injured Levels Of Activity, Aaron D. Sciascia

Theses and Dissertations--Rehabilitation Sciences

Determining return to pre-injured levels of play following athletic injury can be challenging. The current practice of making decisions following rehabilitation as to whether or not a patient has returned to pre-injured levels of activity is potentially inaccurate because initial assessments of perceived physical capability are performed at a time of relative dysfunction or are based on patient recall. Since there is no true baseline of perceived and physical function prior to injury it is difficult to determine if an athlete has return to baseline or is simply better than they were at the time of injury. Therefore, it is …

A Biomechanically Based Observational Tennis Serve Analysis Method Can Be Used To Assess Serve Mechanics, Natalie Myers

Theses and Dissertations--Rehabilitation Sciences

Traditional sports science motion analysis techniques using three-dimensional (3D) kinematics have demonstrated that proper mechanics enhance serve performance and improper mechanics overload tissues resulting in injury. However 3D analysis is costly, time-consuming, and requires extensive knowledge of biomechanical properties and data analysis. Currently there are no simple, reliable, and valid observational methods for health care providers (HCP) and tennis professionals to evaluate tennis serve mechanics. Researchers investigating observational analyses have determined that superior reliability may be a result of specific operational definitions and the incorporation of educational training sessions on how to perform the analysis.

The first purpose of this …

The Effect Of Six Days Of Dietary Nitrate Supplementation On Performance In Trained Crossfit Athletes, Samuel J. Kramer, Daniel A. Baur, Maria T. Spicer, Matthew D. Vukovich

Health and Nutritional Sciences Faculty Publications

Background: While it is well established that dietary nitrate reduces the metabolic cost of exercise, recent evidence suggests this effect is maintained 24 h following the final nitrate dose when plasma nitrite levels have returned to baseline. In addition, acute dietary nitrate was recently reported to enhance peak power production. Our purpose was to examine whether chronic dietary nitrate supplementation enhanced peak power 24 h following the final dose and if this impacted performance in a heavily power-dependent sport.
Methods: In a double-blind, randomized, crossover design, maximal aerobic capacity, body composition, strength, maximal power (30 s Wingate), endurance (2 km …

Perceived Threat Associated With Police Officers And Black Men Predicts Support For Policing Policy Reform, Allison L. Skinner, Ingrid J. Haas

Center for Brain, Biology, and Behavior: Faculty Publications

Racial disparities in policing and recent high-profile incidents resulting in the deaths of Black men have ignited a national debate on policing policies. Given evidence that both police officers and Black men may be associated with threat, we examined the impact of perceived threat on support for reformed policing policies. Across three studies we found correlational evidence that perceiving police officers as threatening predicts increased support for reformed policing practices (e.g., limiting the use of lethal force and matching police force demographics to those of the community). In contrast, perceiving Black men as threatening predicted reduced support for policing policy …

The Lower-Extremity Functional Test And Lower-Quadrant Injury In Ncaa Division Iii Athletes: A Descriptive And Epidemiologic Report, Jason Brumitt, Bryan C. Heiderscheit, Robert C. Manske, Paul Niemuth, Alma Mattocks, Mitchell J. Rauh

Faculty Publications - College of Physical Therapy

Context: The Lower-Extremity Functional Test (LEFT) has been used to assess readiness to return to sport after a lower extremity injury. Current recommendations suggest that women should complete the LEFT in 135 s (average; range 120-150 s) and men should complete the test in 100 s (average; range 90-125 s). However, these estimates are based on limited data and may not be reflective of college athletes. Thus, additional assessment, including normative data, of the LEFT in sport populations is warranted. Objective: To examine LEFT times based on descriptive information and off-season training habits in NCAA Division III (Dill) athletes. In …

Factors Affecting Injury History And Their Overall Impact On Athletic Performance In Distance Runners, Trevor Norris

Williams Honors College, Honors Research Projects

Distance running is a very precise mechanism of many intricate movements and abilities of the body. The amount of miles that a distance runner must run puts a lot of very intense stresses on one’s body. These stresses often appear at the bone level and lead to many injuries such as stress reactions and stress fractures but also may play important roles in tissue damages such as strains and pulls. In this study, we used division one college distance runners and examined many intricacies between their level of fitness and overall composition. These include looking at imbalances, dominant traits, and …

Hydroband: The Continuous Hydration Monitoring System, Karina E. Atkinson, Catherine P. Benedict

Williams Honors College, Honors Research Projects

Dehydration is defined as a mild, moderate, or extreme loss of water in the body. It can result in fever, muscle cramps, headaches, dizziness, or heat stroke in athletes. Ways to determine hydration levels include analysis of the urine, blood, or sweat, body weight changes, skin elasticity tests, and increases in core temperature. Patent search, research journals, and outside studies in the health and fitness market showed that a convenient and continuous hydration monitoring system was not available. Changes in core body temperature proved to be the quickest way to measure hydration levels. The HydroBand system is geared towards athletes …

The Influence Of Hip Mobility And Fatigue On Spinal Flexion And Muscle Activation In Rugby Scrum Performance, Joshua D. Clayton

Theses and Dissertations (Comprehensive)

Introduction: Rugby scrumming is a means of restarting play following a minor rule infringement that can occur up to 28 times per game. The scrum poses a significant injury risk, with more days missed due to injury per event than any other rugby activity. Rugby players also have a significantly higher rate of spine injury than the general population, perhaps due to flexion in combination with high compression forces, which has been cited as the main mechanism of injury. Flexion of the spine has also been associated with poor hip mobility and quadriceps fatigue in other athletic tasks and may …
