UNLV Theses, Dissertations, Professional Papers, and Capstones
Determining body stress levels is important when developing training programs for athletes and rehab facilities. Stress levels during exercise are commonly measured using heart rate, oxygen consumption (VO2), and blood biomarkers. These collection measures involve training on the part of the data collector and the participant, are invasive, and themselves elicit some stress. The purpose of this study is to test whether a 10-min repetitive jumping session will cause a significant increase in salivary alpha-amylase, a potential stress biomarker. This study also looks to determine if a 20-min recovery is enough time for amylase levels to return to …

The Perceived Demands Of Crossfit, Bryanne N. Bellovary
All NMU Master's Theses
Rhabdomyolysis is the breakdown of muscle tissue causing myoglobin, creatine kinase, and other intracellular proteins and electrolytes to leak into circulation, disrupting cell homeostasis. Exertional rhabdomyolysis (ER) occurs after extremely rigorous physical training that could include high amounts of strenuous eccentric exercise. There has been an increase in reports for mild to severe ER as well as other musculoskeletal injuries as the popularity of extreme conditioning programs (e.g., CrossFit®) increases. Therefore, the main purposes of this investigation were to identify: primary risk factors associated with ER during CrossFit®, CrossFit® workouts that might induce a higher risk for the development of …
