New Perspectives On Foot Segment Forces And Joint Kinetics - Integrating Plantar Shear Stresses And Pressures With Multi-Segment Foot Modeling, Dustin A. Bruening, Spencer R. Petersen, Sarah T. Ridge
Faculty Publications
The role of the foot in gait is not well understood, in part due to challenges in capturing and utilizing segmental ground reaction forces. The purposes of this study were to 1) develop methodology to integrate plantar pressure/shear stresses with a multi-segment foot model, and 2) generate and display key normative data from this combined system. Twenty-six young healthy adults walked barefoot (1.3 m/s) across a pressure/shear sensor with markers matching a published 4-segment kinetic foot model. A novel anatomical/geometric masking method was developed that successfully separated regions aligned with model segmentation. This template-based method can be automated and customized …

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.

The Effect Of Acute Creatine Supplementation On Non-Invasive Assessment Of Vascular Function Using Flow-Mediated Dilation, Carson Carruthers
Undergraduate Research Competition
Accumulation of reactive oxygen species within the vasculature has been shown to contribute to endothelial cell dysfunction, an early biomarker of cardiovascular disease. Antioxidants and supplements with antioxidative properties, could be increasingly important in reversing the progression of cardiovascular disease. While creatine monohydrate is commonly used as a fitness supplement to promote increases in muscular strength, recent studies have shown that creatine may act as an antioxidant, thereby improving vascular health. Traditional loading doses of creatine require 7-10 days of 20 g (4 x 5 g/day). However, it may be possible to see the vascular health benefits with a smaller, …

An Examination Of Inter-Limb Functional Asymmetry After A Fatiguing Bout Of Exercise In High Level Soccer Players, Nestor Urrea
Theses and Dissertations
INTRODUCTION: Inter-limb functional asymmetries greater than 15% have been linked to a greater incidence of injury. Moreover, asymmetries greater than 10% have shown greater risk of injury and worsened sport performance, especially for strength and power capabilities, in athletes of multiple sports. Fatigue and sex are factors that seem to influence injury rates as well as greater asymmetries between limbs. This research project aims to investigate the effects of a fatiguing bout of exercise in strength and power inter-limb functional asymmetries in male and female soccer players. It was hypothesized that strength and power asymmetries are negatively affected after a …

The Effect Of Caffeine Supplementation On Figure Skating Jump Height, Hailey Jordan
Senior Honors Theses
The consumption of caffeine has many physiological effects beneficial to athletic performance and has great potential as an ergogenic aid. Significant studies support the idea that caffeine supplementation enhances muscular endurance, muscular strength, and muscle power output, all important components to a technically advanced figure skating jump. A single-blind within-subjects study in which participants from the Liberty University Figure Skating Team tested their off-ice loop jump height over two trials (caffeine and placebo), investigated the relationship between caffeine and figure skating jump height. The results of the study suggest that caffeine supplementation increases off-ice loop jump height.

Attenuated Skeletal Muscle Metabolism Explains Blunted Reactive Hyperemia After Prolonged Sitting, Cody Anderson, Elizabeth Pekas, Michael Allen, Song-Young Park
UNO Student Research and Creative Activity Fair
Introduction: Although reduced post-occlusive reactive hyperemia (PORH) after prolonged sitting (PS) has been reported as impaired microvascular function, no specific mechanism(s) have been elucidated. One potential mechanism, independent of microvascular function, is that an altered muscle metabolic rate (MMR) may change the magnitude of PORH by modifying the oxygen deficit achieved during cuff-induced arterial occlusions. We speculated that if MMR changes during PS, this may invalidate current inferences about microvascular function during PS. Objective: Therefore, the objective of this study was to examine if peripheral leg MMR changes during PS and to ascertain whether the change in the oxygen deficit …
