Relationship Between One Repetition Maximum Parallel Squat And Jump Squat Peak Power, Corey Klitzke

Masters Theses

Jump squats are a simple exercise that can be used to train lower body power. Unlike many other methods of power training, jump squats do not require any specialized equipment (platforms, bumper plates, etc.). Jump squats can be used when other forms of power training are not available or are not allowed. In order to most efficiently train power, the intensity must balance force and velocity. The purpose of this study was to find the intensity that yields the peak power output of a jump squat. 12 participants (9 males, 3 female) participated in the study. Each participant completed a …

The research presented in this study examines concussion among athletes from the perspectives of prevention, assessment, and recovery. The first study examines concussion education for high school athletes by surveying 157 collegiate athletes, who primarily attended high school in Illinois and Indiana, about the previous concussion education, including whether they received mandated education, the methods and providers of education, and their ability to name a variety of concussion symptoms. This study finds that despite legislative mandates in these states, 20% of student-athletes continue to report not receiving concussion education in high school, with females more likely to report not receiving …

Administrative Barriers To Compliance With The 2010 Ncaa Policy On Concussion Management, Tyler Norman

Dissertations

Concussions and concussion management in sport have become a polarizing public health issue. The best concussion assessment practices and “return-to-play” guidelines have been debated in both the scientific arena and in the media. At risk is the health of the athletes when proper diagnosis and treatment are not accurate for this potentially devastating injury.

Recent research estimates that approximately 1.6 – 3.8 million sport-related concussions occur each year in the United States (Brady, 2011), which can lead to chronic disease, swelling of the brain, cognitive impairment, chronic headaches, mood disorders, depression, blurred vision, double vision, cranial hemorrhaging and death if …

Incidence Of Head Injury Among Synchronized Skaters: Rates, Risks, And Behaviors, Gretchen L. Mohney

Data regarding risk and rates for head injury and concussion specific to the sport of synchronized skating is absent from literature. This study investigated the rate and risk for head injury and concussion as a function of team level, identified behaviors to include education, neurocognitive baseline screening and protective equipment utilization, and the implementation of return to sport protocols.

An anonymous cross-sectional survey was implemented at the 2018 U.S. Synchronized Skating Championships. Participants were female members of a qualifying team, ages 13 and older, at the intermediate participation level and higher. The survey response rate was 42% (520/1232). Among the …

Mechanical Loading As Potential Treatment For Wnt Inhibitor Induced Bone Loss, Juraj Zahatnansky Md, Daniel Dick, Gabrielle Foxa, Robert Baker, Bart Williams Phd

Research Day

The Wnt signaling pathway has been shown to play a role in bone homeostasis and carcinogenesis. On the one hand, a decrease in signaling has been associated with a decrease in bone mass, on the other, an increase in signaling with cancer development. LGK974 is a Wnt signaling inhibitor currently being investigated as a potential cancer therapeutic agent. This molecule inhibits Porcupine, a transmembrane protein necessary for Wnt ligand secretion. In light of the above and based on our preliminary data, treatment with LGK974 leads to bone mass loss. Our investigation aims to address whether such bone loss can be …

Benefit Of Ultrasound Curriculum Development For Family Medicine Residents, Nithin Natwa, Uzair Munshey, Duncan Vos, Robert Baker

Research Day

Introduction/Purpose: Musculoskeletal problems comprise some of the most common reasons for ambulatory care encounters in the United States, accounting for 8.3% of the 1.2 billion visits per year according to the CDC. Musculoskeletal Ultrasound use has become more common in primary care for diagnosis and therapeutics. In Family Medicine Residency (FMR) Programs there is a deficiency of a structured, competency-based musculoskeletal ultrasound (MSK US) training despite its growing popularity. Currently, there is no formalized requirement for Ultrasound education as in other residency programs in spite of its benefit. Methods: We received a positive response on our needs analysis survey for …

Effectiveness Of Improving Performance With The Bigger Faster Stronger In-Season Training Program, Alicia D. Crelinsten

Masters Theses

This study investigated the effectiveness of improving performance of adolescents with the in-season Bigger Faster Stronger (BFS) program. Thirty seven high school athletes were divided into three groups; BFS (n=l4 ), traditional weight training (n= l0), and control (n= 13 ). Each participant went through a battery of seven performance pre-tests and post-tests ( estimated 1 ORM incline bench, broad jump, one minute sit-up test, t-test, line drill, 40 yard sprint, 1.5 mile run). Following the pre-testing, the control group continued to participate in their sport. The BFS group participated in the in-season BFS program (30 minute supervised session consisting …

The Effect Of Acute Resistance Training On Resting Metabolic Rate In Men, Steven William Ball
