Ketogenic Diet As A Preventative Measure Or Treatment Option For Osteoarthritistargeting Nfl Athletes As A High-Risk Group, Kelsi J. Smith

Selected Honors Theses

Osteoarthritis (OA) is a prevalent joint disease that results from the degradation of articular cartilage, leading to inflammation, pain, and eventual joint failure. At one time, it was thought that OA was only the result of the natural decline experienced in old age; however, various risk factors have now been identified that may contribute to an increased risk for developing OA. Risk factors may include joint loading, altered biomechanics, obesity, and joint injury, to which athletes are exposed at a high rate. NFL athletes are one group of athletes that have continued to show a high prevalence of arthritis in …

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano May 2019

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano

Journal of Human Performance in Extreme Environments

Technical freediving can be defined as freediving augmented by the use of oxygen-enriched gases or oxygen before, during, or after a freedive. As a result of these techniques, breath-hold divers can visit and enjoy underwater wrecks, reefs, and other diving locations previously located at depths unreachable to apnea divers. By pre-breathing oxygen-enriched gases in conjunction with hyperventilation—which decreases the partial pressure of carbon dioxide (PCO2)—the technical freediver now has additional oxygen to facilitate aerobic respiration during the dive. In addition, pre-breathing oxygen decreases tissue nitrogen tensions, which limits inert gas loading and decreases the risk of decompression sickness (DCS). Finally, …

Estimating Variations In Metabolic Cost Within The Stride Cycle During Level And Uphill Walking, Arash Mohammadzadeh Gonabadi

UNO Student Research and Creative Activity Fair

Indirect calorimetry provides the average cost of a stride cycle and prevents from identifying which part of the gait cycle causes increased metabolic cost in patients, however, recent simulation methods allow estimating the time profile of metabolic cost within the stride cycle. In this study, we compare the estimations of the time profile of the metabolic cost of two simulation methods for level and uphill walking. We used kinematic, kinetic and electromyography data from level and uphill walking (one participant) to estimate the time profiles of metabolic cost using the muscle-level metabolic model of Umberger using electromyography and kinematic data …

The Energy Paradox Of The Ankle-Foot Complex During Human Walking, Nikolaos Papachatzis, Kota Takahashi

UNO Student Research and Creative Activity Fair

Flexor hallucis longus (FHL) is a multiarticular muscle that possesses the potential to alter foot’s functional and mechanical behavior, since it performs multiple significant functions during walking (e.g supports the medial longitudinal arch of the foot).The purpose of this study was to determine if the functional changes of the FHL are associated with the foot’s adaptations to the mechanical demands of walking. Backward walking is an experimental method capable of altering how the forces propagate underneath the foot and disrupting the mechanical function of the FHL muscle. We hypothesized that: (1) the muscle activity of the FHL will increase during …
