Showcase of Graduate Student Scholarship and Creative Activities

This project objectives were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. Seventeen recreationally trained female cyclists completed four trials consisting of 3 kilometer time trials. Subjects ingested either caffeine or a placebo one hour prior to each trial. The magnitude of the ergogenic aid of caffeine was compared between oral contraceptive users and eumenorreheic females. In addition, the effect of caffeine was compared across different phases of the menstrual cycle, specifically the follicular and luteal phases.

Dance As A Protective Measure Against The Cognitive And Physical Declines Associated With Aging: A Proposed Study, Sarah M. Schwanz, Jeffrey Holmes, Jessica Grahn

Western Research Forum

Background:

Dance is considered a multimodal activity in that it requires both physical and cognitive engagement. Combining physical activity with music may have a synergistic effect, enabling dance to enhance physical and cognitive functions more than music and physical activity alone. The positive changes attributed to dance training such as improved visuospatial and motor ability, high coordination, greater balance, and increased cognitive ability may also benefit individuals as they age.

Methods:

This proposed study will examine whether dance training has the potential to protect against age-related cognitive and physical decline by assessing the cognitive and physical domains that show decline …

Where On Ice? Algorithmically Deconstructing Nhl Shot Locations As A Method For Player Classification, Devan Becker, Douglas G. Woolford, Charmaine B. Dean

Repetitive Mild Traumatic Brain Injury Impairs Performance In A Rodent Assay Of Cognitive Flexibility, Christopher P. Knapp, Doug P. Fox, Ramesh Raghupathi, Laura L. Giacometti, Stan B. Floresco, Barry D. Waterhouse, Rachel L. Navarra

Rowan-Virtua Research Day

Mild traumatic brain injury (mTBI) occurs in almost 80% of the 3 million reported cases of TBI-related emergency department visits each year in the United States. The majority of mTBIs, sometimes classified as concussions, are due to sports-related activities and typically occur repeatedly over the course of an athlete’s career. mTBI symptoms are generally classified as either somatic or neuropsychiatric/cognitive in nature and include impairments in prefrontal cortex mediated functions, including attention, memory, processing speed, reaction times, problem solving, and cognitive flexibility. To date, there remains a major gap in our understanding of the behavioral manifestations, underlying neurobiology, and treatment …

The Relationship Between Objective And Subjective Markers Of Training Stress In Ncaa Division I Women Basketball Players, Casey Pederson, Courtney Elliott, James Hutson

Undergraduate Research Conference

An athlete’s training stress score (TSS) is an objective marker of overall training volume and can be determined by tracking total time spent at specific heart rate (HR) zones. Additionally, an athlete’s power factor (PF) or explosive strength is an important marker of performance and can be measured objectively with power testing equipment. While these measures of training stress and performance are important, a coach with limited resources may not have access to the equipment or expertise to measure these variables. On a subjective level, perceived recovery status (PRS) prior to practice and the rating of perceived exertion (RPE) during …

"Get Tough!": A Case Study On The Development Of The Sport Ethic In Youth Lacrosse, Ross Budziszewski

Student Research Symposium

While participation in youth sport is often linked with positive psychosocial and physical outcomes (Holt et al., 2017), this context can also cultivate ideals that lead to the development of unethical beliefs and unsafe sport practices (Al-Yaarbi & Kavussanu, 2017). The sport ethic is described as the deviant overconformity by an athlete to fit societal expectations of a sport's high-performance culture (Hughes & Coakley, 1991). Strong beliefs in the sport ethic can lead to moral disengagement, antisocial behavior, and treating sport like warfare (Shields, Funk, & Bredemeier, 2015). Although the sport ethic has been widely studied in competitive adult sport, …
