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: …

Exploratory Analysis Of Ptsd Severity And Objective Measures Of Physical Activity Among Combat Veterans, Danny O. Sauceda

Theses and Dissertations

Strong levels of motivation, relatedness and self-determination support the likeliness of participating in habitual exercise. Compared to nationwide estimates, research has demonstrated fitness and performance is significantly lower among those suffering from PTSD. Meeting established recommended daily levels of physical activity (PA) for individuals with PTSD is critical for their physical and mental health status over a lifetime and factors supporting or hindering adherence to habitual exercise are lacking. Furthermore, regular PA among combat Veterans with Posttraumatic Stress Disorder (PTSD) is a viable and substantial treatment option to improve physical health status and cognitive well-being. The purpose of this exploratory …
