Impact of acute exercise on microRNAs related to concussion symptoms

Concussions, or traumatic brain injury (TBI), are a serious medical problem affecting approximately 1.7 million people in the United States each year. Current tools for analysis of concussion include the Glasgow Coma Scale, SCAT5, computerized topography (CT) and magnetic resonance imaging (MRI), however, these tools are typically not indicative of the range and severity of symptoms a patient may experience. Recent studies have explored the use of microRNAs as a biomarker for TBI severity in patients who have already experienced a TBI. We seek to investigate the microRNA levels in …

Effects Of Static Stretching On Proprioception And Muscle Power Production, Eva Alyss Blais

Honors College Theses

With widespread use of pre-exercise stretching methods in many sports, recent studies have questioned how effective these implications are (Kay, Blazevich 2012, Cramer, J. T., et al.2005, Curry, B. S., Chengkalath, D., Crouch, G. J., Romance, M., & Manns, P. J. 2009). It has been found that certain types of stretching before performance negatively impact muscle power production. However, the reasoning behind why stretching is doing harm to athletes’ performances is still unanswered. The purpose of this study is to explore how stretching affects proprioception, and how this in turn affects muscle power production. Using the Biodex 2 dynamometer, passive …
