Influence Of Cardiovascular Risk Factors On Remote Ischemic Preconditioning, 2016 South Dakota State University
Influence Of Cardiovascular Risk Factors On Remote Ischemic Preconditioning, Tiffany Trachte
Electronic Theses and Dissertations
A powerful therapy against microvascular endothelial ischemia-reperfusion injury is remote ischemic preconditioning (rIPC), which triggers tissue protection by exposing a limb to small cycles of vascular occlusion. Animal models indicate that CVD risk factors reduce the protective benefits of ischemic conditioning. However, there are no human studies investigating how a burden of risk factors interferes with rIPC to prevent endothelial injury. The purpose of the present study was to determine the influence of risk factor burden on the capacity of rIPC to prevent endothelial reperfusion injury in humans. Twenty-two (age: 45±14 yr., BMI: 31±8 kg/m2) sedentary adults (12 lower burden: …
The Correlation Between Strength Levels Measured Through Dynamic Strength Exercises And The Incidence And Severity Of Injury Among Collegiate Athletes, 2016 South Dakota State University
The Correlation Between Strength Levels Measured Through Dynamic Strength Exercises And The Incidence And Severity Of Injury Among Collegiate Athletes, Alex Jardine
Electronic Theses and Dissertations
Injury to athletes in sport occurs as a result of extrinsic and intrinsic risk factors. Mounting evidence points toward decreased strength as a predictor of injury in athletes. By comparing strength levels in functional movement patterns to injury, the strength and conditioning professional will be able to design effective training programs to reduce the incidence of injury in sport better. The purpose of this study was to determine the correlation between strength measured through dynamic strength exercises (power clean, the squat, and the bench press) among collegiate athletes and the incidence and severity of injury. We hypothesized that greater incidence …

Nonalcoholic Fatty Liver Disease: Cause To Treatment, Tavleen Aulakh
Occam's Razor
Imagine two individuals, both suffering from severe liver damage. With excess fat molecules concentrated in the hepatic cells, their livers are inflamed and scarred. These deteriorating livers are also supplementing the development of chronic obesity, diabetes, cardiovascular diseases, and hyperlipidemia. While one of these individuals is a middle-aged male with a long history of alcohol addiction and abuse, the other is only thirteen years old and has never consumed alcohol. This adolescent is suffering from nonalcoholic fatty liver disease (NAFLD).

Exercise and Sport Studies: Faculty Publications
Circulating angiogenic cells (CAC) influence vascular repair through the secretion of proangiogenic factors and cytokines. While CAC are deficient in patients with diabetes and exercise has a beneficial effect on CACs, the impact of these factors on paracrine secretion from CAC is unknown. We aimed to determine whether the in vitro secretion of selected cytokines and nitric oxide (NO) from CAC is influenced by hyperglycemia and acute exercise. Colonyforming unit CAC (CFU-CAC) were cultured from young active men (n = 9, 24 ± 2 years) at rest and after exercise under normal (5 mmol/L) and elevated (15 mmol/L) glucose. Preliminary …

A Comparison Of Warm-Up Modalities On Upper Body Force Production Measures, 2016 University of Mississippi. Sally McDonnell Barksdale Honors College
A Comparison Of Warm-Up Modalities On Upper Body Force Production Measures, Mary G. Langford
Honors Theses
Warm-ups are often initiated before an athletic event in order to prepare the athlete's body for competition by increasing blood flow to the working muscles. When a warm-up also activates nerve-muscle function, producing a level of high-intensity power even after the muscle contraction occurs, it is known as post-activation potentiation (PAP). Most PAP warm-ups include high-load, low-velocity conditioning contractions whereas a low-load, high-velocity conditioning contraction may be a more user-friendly warm-up. Therefore, the purpose of this study was to investigate the effects of PAP after low-load, high-velocity conditioning contractions on subsequent upper body power exercises. Ten recreationally trained males (age: …
