Does A Brisk Six Minute Walk Cause Upper Body Fatigue In Females, Kaden Buford Apr 2023

Does A Brisk Six Minute Walk Cause Upper Body Fatigue In Females, Kaden Buford

Symposium of Student Scholars

Non-local performance fatigue (NLPF) can be described as performance decrements occurring for a muscle group that was not directly involved in the fatiguing activity that preceded. Most studies on NLPF involve strenuous exercise of an isolated joint in trained populations, however, little evidence exists on NLPF derived from activities mimicking acts of daily living. Determining whether NLPF exists following brisk walking is worthwhile, and rate of force development (RFD), the rate at which muscle force is produced, may possess increased susceptibility compared to maximal strength. The purpose of our ongoing study is to determine the responses, if any, for maximal …

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Warming up before exercise increases muscle metabolism and reduces the risk of injury. Soccer players are prone to lower limb injuries, therefore a warm up that reduces injury and improves performance is ideal. Foam rolling is known to reduce delayed onset muscle soreness, loosen muscle fascia, and promote blood flow to muscles when utilized post-exercise. As such, the inclusion of foam rolling in conjunction with a dynamic warm up prior to exercise may further reduce injury risk and optimize performance. However, current research has not examined the relationship between combining foam rolling with a dynamic warm up on exercise performance. …


A Christian Framework For Competitive Sport, Owen Leibrock Apr 2023

A Christian Framework For Competitive Sport, Owen Leibrock

22nd Annual Celebration of Undergraduate Research and Creative Activity (2023)

Christianity and competitive sport have a long history of interaction, oftentimes adversarial in nature. Yet in the last century and a half, Christians have embraced sport in such foundational ways that it is often now hard to imagine sport without certain Christian ideas and images. Competitive sport has taken on many forms and has been used in many ways both destructive and constructive. This wide range of Christian responses to sport throughout history begs the question: Does competitive sport truly fit within a framework of Christian ethics and values?

In order to answer this question, I will engage with theories …

Energy Availability In Female Collegiate Beach Volleyball Athletes, Meghan Thomas Apr 2023

Energy Availability In Female Collegiate Beach Volleyball Athletes, Meghan Thomas

Undergraduate Research Competition

BACKGROUND: Energy availability (EA) is the amount of energy available for normal physiological processes and is defined as energy intake (kcals) minus exercise energy expenditure (kcals) relative to fat free mass (FFM). Low-energy availability (LEA; i.e., energy intake < 30 kcal/kg FFM/d) causes Relative Energy Deficiency in Sport, which results in various negative health and performance outcomes. A recent study reported 81% of the female collegiate athletes examined exhibited LEA. Of the 18-collegiate beach volleyball (BVB) athletes studied, average EA across 7 days was determined to be 12.44 kcal/kg FFM/d. Notably, this is a 7-day snapshot that may not reflect chronic dietary or training patterns. To our knowledge, no study has examined EA across the 10-week competitive season in this population. Therefore, the purpose of this cross-sectional study is to establish the risk of LEA in female collegiate BVB athletes across the competitive season. METHODS: We plan to recruit 18 female collegiate BVB athletes. Each subject will complete an initial visit where anthropometrics, resting metabolic rate (RMR), nutrition knowledge, psychological skills and maximal aerobic capacity will be tested. During weeks 1, 5, and 9 of the competitive season, in addition to initial testing, energy intake (ASA 24) and energy expenditure (GT9X-Link) will be assessed to calculate EA. Countermovement vertical jump height, velocity, and power (GymAware) will be used to assess performance. Results will be analyzed using repeated measures ANOVA and Pearson Correlations. EXPECTED RESULTS: It is hypothesized that LEA will be present and EA will decline as the season progresses.
