Increased Sod2 In The Diaphragm Contributes To Exercise-Induced Protection Against Ventilator-Induced Diaphragm Dysfunction, Stephanie E. Hall Jan 2019

Increased Sod2 In The Diaphragm Contributes To Exercise-Induced Protection Against Ventilator-Induced Diaphragm Dysfunction, Stephanie E. Hall

Kinesiology Faculty Publications and Presentations

Mechanical ventilation (MV) is a life-saving intervention for many critically ill patients. Unfortunately, prolonged MV results in rapid diaphragmatic atrophy and contractile dysfunction, collectively termed ventilator-induced diaphragm dysfunction (VIDD). Recent evidence reveals that endurance exercise training, performed prior to MV, protects the diaphragm against VIDD. While the mechanism(s) responsible for this exercise-induced protection against VIDD remain unknown, increased diaphragm antioxidant expression may be required. To investigate the role that increased antioxidants play in this protection, we tested the hypothesis that elevated levels of the mitochondrial antioxidant enzyme superoxide dismutase 2 (SOD2) is required to achieve exercise-induced protection against VIDD ...

Effects Of Preseason Concussion Education On Self-Reported Likelihood And Confidence In Concussion Reporting, Dana Edward Cash Jan 2019

Effects Of Preseason Concussion Education On Self-Reported Likelihood And Confidence In Concussion Reporting, Dana Edward Cash

Graduate Theses and Dissertations

Around three million concussions happen in the United States from sport and recreational activity alone, and it is estimated 50% of concussions go undiagnosed. Collegiate athletes have been found to not report their symptoms of concussion mainly because they felt their symptoms were not severe enough and they did not think there were any long-term consequences from continuing to play. This study attempts to find if preseason concussion education for collegiate hockey players and club athletes changes their perceptions about concussions, and if these changes are maintained after returning to sport/competition. This study used three identical surveys over three ...

Seasonal Changes In Sleep, Rpe, And Scoring Percentage In Division One Collegiate Female Basketball Players, Lindsay Perrin, Dr. Stephen Rossi

University Honors Program Theses

Basketball season occurs over several months and involves heavy traveling, training, competing, and scholarly duties. These demands do not allow much time for rest and recovery. A lack in the quantity and quality of sleep can reduce the ability to manage stress and reduce recovery from training and competition. This can affect the health and well-being of the athlete and their success on the court. In college, sleep schedules may change from high school by staying up later and sleeping in more. College students typically sleep between six and seven hours a night which is less than the recommended nine ...

Do Humans Prioritize Time, Energy, Intensity… Or Something Else Altogether When Making Decisions About Walking On Level Vs. Uphill Surfaces?, Helena Gabrielle Meyer Jan 2019

Do Humans Prioritize Time, Energy, Intensity… Or Something Else Altogether When Making Decisions About Walking On Level Vs. Uphill Surfaces?, Helena Gabrielle Meyer

Undergraduate Honors Theses

During daily life, people walk from one point to another. Sometimes they choose to walk along designated paths; other times they take shortcuts. To determine how humans weigh costs like time, metabolic energy expenditure, and metabolic intensity, I studied subjects making walking decisions about walking up a hill vs. along a level surface for various distances. I hypothesized that subjects would be indifferent to walking uphill at an 8.5% grade vs. on the level when the two options required the same time or the same amount of metabolic energy.

Further, I hypothesized that subjects would walk at speeds such ...
