Comparing Men’S Soccer Head Impact Characteristics Over A Three Year Time Period, Karlie Ennis

Student Scholar Showcase

By studying head impacts over multiple seasons, injury patterns may be recognized which can lead to rule changes and other injury reduction measures. The purpose of our study was to compare head impact characteristics (impact location and mechanism) in men’s soccer over 3 years. We recruited 26 NCAA Division III intercollegiate male soccer players (age=19.64±1.25 years, height=181.70±5.80 cm, mass=76.98±10.19 kg) over 3years. X2 Biosystems xPatch sensors measured frequency and magnitude of all head impacts over a 10 g threshold. The overall male soccer player IR was 7.50/1000 athlete-exposures (CI₉₅=2.85-12.15). The most common head impact mechanism was ball …

An Anatomical And Functional Analysis Of Digital Arteries, Katie Highsmith

Student Scholar Showcase

Blood flow to the tissue of the hands and digits is efficiently regulated by vasoconstriction and vasodilation. Through a series of cadaveric dissection, we examined arteries in the hands and digits, including ulnar artery, radial artery, palmar arteries, and digital arteries, for their distribution (branching) patterns and morphological parameters (e.g., thickness, length between branches, external and internal diameters). Using data directly collected from three female cadavers as input variables to our mathematical model, we simulated vasoconstriction (-20% and -10% diameter) and vasodilation (+10% and +20 diameter) to evaluate the extent of changes in blood volume and flow within the arteries. …

Exploration Of Prostate Cancer Cells: The Significance Of Active Herv, Dakota Shepherd

Student Scholar Showcase

The second most common cancer in men is prostate cancer. Prostate cancer is traditionally diagnosed by a digital rectal exam. Blood tests can also be used to test for PSA (prostate-specific antigen). These two methods can be used together but can sometimes provide both false negative and false positive results. A new method of testing for prostate cancer could prove to be beneficial. Previous studies have shown that active HERV sequences have been identified in some cancers, including prostate cancer. We hypothesize that the presence of active HERV in prostate cancer lines is significant. In this study, rabbit polyclonal antibodies …

Mobilization Of Calcium Across Mineralized Tissues In Yellow Perch, Perca Flavescens, Taylor Bopp

Student Scholar Showcase

Bones in many higher teleost fish, such as percids and centrarchids, lack osteocytes that function as both chemo- and mechano-sensors, and thus, are not actively involved in homeostasis of blood calcium level. Nonetheless, the vertebrae of yellow perch, Perca flavescens (P. flavescens), living in darker and low calcium (Ca) water, have demonstrated adaptive modeling and remodeling of vertebrae to be more mineralized and thus enhance transmission of the axial muscle torque into the thrust force for the C-start predator escape behavior. The prey-predator interaction is expected to occur at closer range between prey fish and predator fish in …

Comparing The Incidence Of Head Impacts Sustained In Conference Versus Non-Conference Women’S Soccer Games, Courtney Acors

Student Scholar Showcase

Context: Investigating head impacts in women’s soccer has become of increased interest due to women’s soccer having one of the highest concussion injury rates among organized sports.

Objective: To determine frequency and magnitude differences in head impacts sustained by collegiate women’s soccer players during conference and non-conference game. Design: Descriptive epidemiology study.

Setting: Soccer fields. Participants: 24 intercollegiate women’s soccer players (age=19.65±1.27 years, height=165.80±4.87 cm, mass = 64.45±7.38 kg). Interventions: Game type served as the independent variable (non-conference and conference). We measured frequency and magnitude (peak linear accelerations in g-forces and peak rotational accelerations in deg/sec2) of head impacts with …

The Effect Of Previous Medical History On Student-Athlete Quality Of Life, Rachael Watkins

Student Scholar Showcase

Health-Related Quality of Life (HRQL) assessments can provide Athletic Trainers with information about student-athletes’ overall well-being and health. The objective of this study was to examine the association between personal and family reports of medical history and HRQL in collegiate student-athletes. We recruited 271 student-athletes (age=19.00±1.15 years, height=175.18±4.29 cm, mass=72.29±12.03 kg). The independent variables included the presence of any family (parents, siblings, grandparents) or any personal history of balance disorders, psychological disorders, memory disorders or history of headaches. The dependent variables included the 9 subsets of HRQL (anxiety, depression, fatigue, pain interference, pain intensity, physical function, sleep disturbance, social roles) …

Functional Movement Patterns And Perceived Mobility In Collegiate Lacrosse Athletes, Christopher J. Rosenborough

Student Scholar Showcase

Context: The stress on the body from sport participation may play a role in an athlete’s ability to function throughout a season. The primary objective of this study was to examine the effects of a non-traditional lacrosse fall season on functional movement patterns for both males and females. Our second objective was to observe how collegiate lacrosse athletes perceived mobility.

Methods: Fifty males (age=19.38+1.24 years, height=182.63+6.16 cm, mass=82.37+8.46 kg) and 22 females (age=19.68+1.17 years, height=165.10+6.88 cm, mass=64.09+8.72 kg) who participated on National Collegiate Athletic Association Division III lacrosse teams volunteered to participate. Independent variable was time (pre, post). …

The Perception Of Head Impacts Sustained By Collegiate Baseball Catchers: A Pilot Study, Caleb Johnston

Student Scholar Showcase

Repetitive subconcussive head impacts have been studied in a variety of contact sports and have been found to impair performance in football, soccer, hockey, and lacrosse athletes. To our knowledge no one has investigated the frequency of head impacts in the sport of collegiate baseball. To date, athlete perceived number of head impacts and actual head impacts recorded during participation have not been compared. A sample of 3 baseball catchers from one National Collegiate Athletic Association (NCAA) Division III baseball team were studied.Our results indicated perceived game impacts did not differ from actual game impacts (t₂=1.76, P=.23; …

The Effects Of Soft Tissue Flossing On Hamstring Flexibility And Lower Extremity Power, Zack Maust

Student Scholar Showcase

Flossing includes wrapping a latex band around a joint or muscle group providing compression and partially occluding blood flow followed by performing exercises. Flossing is hypothesized to improve flexibility by dissipating myofascial adhesions. The purpose of this study was to determine if applying a floss band to the thigh would increase hamstring flexibility as well as lower extremity power. Our study included 21 active individuals(8 male, 13 female, 22.62±2.99 years, 171.52±9.08 cm, 73.57±11.37 kg).The participant first warmed up on a stationary bike, followed by hamstring flexibility measurement of supine hip flexion. After the flexibility test, we used a single-leg vertical …
