Optimization Of Underbody Blast Energy-Attenuating Seat Mechanisms Using Modified Madymo Hybrid Iii And Human Body Models, Kelly Erin Bryan Bosch

Wayne State University Dissertations

Energy attenuating (EA) blast seats, although not new to the market, have not been fully characterized with respect to energy attenuation capability and the resulting effects on occupant protection. EA seats utilize stroking mechanisms to absorb energy and reduce the vertical forces imparted on the occupant’s pelvis and lower spine complex. Although a variety of EA seats are available on the market, the fundamental question behind how to optimize the force and deflection rates of the EA mechanisms to effectively reduce occupant injury has not yet been answered. Using modeling and simulation techniques, this research developed a tool to determine …

Student-Athlete Compensation: An Alternative Compensation Model For All Athletes Competing In Ncaa Athletics, Mike Stocz, Nicholas Schlereth, Dax Crum, Alonzo Maestas, John Barnes

Kinesiology

The Ed O’Bannon case (O’Bannon v. National Collegiate Athletic Association, 2015) has brought student-athlete compensation to the national spotlight. While the NCAA continues to defend its policy of amateurism, the time for college athlete compensation may soon become a reality (NCAA Division I Manual, 2019). Recent college athlete compensation models have explored revenue sharing models similar to that of professional sports leagues, although previous research failed to develop a compensation model for athletes in sports beyond basketball and football (Huma & Staurowsky, 2013). The current research argues for a more applied, market-economy compensation model to offer fair compensation to collegiate …

Effects Of Psychological Stress During Exercise On Markers Of Oxidative Stress In Young Healthy, Trained Men, Matthew J. Mcallister, Steven A. Basham, Hunter S. Waldman, Johneric W. Smith, Joni A. Mettler, Matthew B. Butawan, Richard J. Bloomer

Kinesiology

Those engaged in high stress occupations such as firefighters and military personnel are exposed to a variety of psychological and physiological stressors. The combination of mental and physical stress [i.e., dual stress challenges (DSC)] results in significant increases in stress hormones, which causes oxidative stress (OS) and contributes to elevated risk for cardiovascular disease. However, data are needed to determine the impact of DSC on markers of OS in exercise-trained individuals.

The First Step Toward The Future Of Wearables In Rehabilitation, Morgan L. Andrews

Lewis Honors College Capstone Collection

Tibial stress fractures are a major problem for runners and military athletes due to the high-intensity nature of their training. This injury is commonly treated through subjective measures including rest and management of symptoms that are evaluated by a therapist or trainer. With the advancement of technology such as inertial measurement units with accelerometers, clinicians may have the potential to provide an objective way to rehabilitate tibial stress fractures. Wearable technology is becoming more popular to be used in training but has not made it to rehabilitation yet. This study examines the validity of derived measures from the IMeasureU IMU …

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. Cause …

How does POGIL fit inro grading schemes for assignments, tests, and the course? POGIL activities are not designed robe graded as assessments; rather, they are intended as learning tools. However, one of the principle process skills targeted by POGIL is assessment—specifically self-assessment. Thus, much of the grading and assessment in a …

Neuromuscular Electrical Stimulation: A Novel Treatment Intervention For Improving Metabolic Health In An Overweight/Obese Population, Michelle J. Galvan

Open Access Theses & Dissertations

Background: Most U.S. adults (80%) do not meet minimum exercise recommendations by ACSM (CDC, 2015). Using an in vitro primary cell culture model, we and others have shown that muscle contraction induced by electrical stimulation results in increased glucose transporter 4 (GLUT4) protein, glucose uptake and mitochondrial content. Neuromuscular electrical stimulation (NMES) is a novel alternate strategy to induce muscle contraction, using electrical impulses. However, effectiveness of NMES induced muscle contraction to improve insulin sensitivity and energy expenditure is not clear. The purpose of this study was to investigate the effects of four weeks of NMES on insulin sensitivity in …

Resistance training can be periodized numerous different ways, but the most popular training methods are traditional periodization, undulating periodization, and plyometric training. This systematic review and meta-analysis examined studies that compared traditional periodization, undulating periodization, …

Using Maximum Power As A Variable For 1rm Prediction In The Squat And Bench Press, Sean O'Connor

Electronic Theses and Dissertations

Many Strength and Conditioning (S&C) coaches utilize a one-rep max (1RM) exercise test to gauge the maximal strength of athletes, and then prescribe resistance training programs based on a relative percentage of 1RM to obtain strength or power adaptations. However, many S&C coaches have raised questions regarding the safety and necessity of a 1RM test. Attempts to mitigate the weaknesses of 1RM testing have led to other methods of testing including repetition max testing (3RM, 5RM, 10RM, etc.) as well as load/velocity profiling. The main purpose of this study is to determine if 1RM can be accurately estimated from maximal …

Group-Based Physical Activity Trajectories In Children Transitioning From Elementary To High School, Russell R. Pate
