Cardiovascular Disease Risk And Menopause: Effects Of Cardiorespiratory Fitness, Exercise, And Follicle Stimulating Hormone, Corinna Serviente
Cardiovascular Disease Risk And Menopause: Effects Of Cardiorespiratory Fitness, Exercise, And Follicle Stimulating Hormone, Corinna Serviente
Doctoral Dissertations
Menopause is associated with adverse changes in cardiovascular disease risk factors. A reduction in estrogens is most commonly associated with changing cardiovascular disease risk; however, recent observations suggest that the increase in follicle stimulating hormone that accompanies menopause may also influence risk, potentially through its influence on lipid levels. The changes in cardiovascular disease risk factors may adversely affect endothelial cell function, a pre-clinical marker for cardiovascular disease. Whether cardiorespiratory fitness is protective of endothelial health in this population, thereby mitigating the changes in risk that accompany menopause, is unclear. This dissertation evaluated differences in endothelial health and endothelial responses …
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Effects Of Instability On Core Muscle Activation In A Side Bridge, Erin E. Kishman
Masters Theses
Training the musculature of the core continues to be perceived as an essential component of conditioning and rehabilitation settings (11). A popular way to train the core is with the use of instability devices, such as Swiss ball or suspension trainer. However, there is limited research on the effects of these devices on core muscle activity. The purpose of this study was to examine core muscle activity during side bridge variations with and without instability devices (Floor, Swiss Ball, and TRX) through electromyography (EMG) of the rectus abdominis, external oblique, erector spinae, and latissimus dorsi. 39 participants performed three variations …
Multi-Tissue Examination Of Exercise Or Metformin On The Consequences Of Doxorubicin Treatment, Amy Dee Mackay
Multi-Tissue Examination Of Exercise Or Metformin On The Consequences Of Doxorubicin Treatment, Amy Dee Mackay
Theses and Dissertations
Doxorubicin (DOX) is an effective chemotherapeutic treatment with lasting deleterious side effects in heart and skeletal muscle. As an increased percentage of patients live many years past their cancer treatments, addressing the long-term side effects of chemotherapy treatment becomes critical. In an attempt to prevent heart and skeletal muscle damage caused by DOX, two co-treatments, exercise (EX) or metformin (MET) were studied for their effectiveness in maintaining muscle function, mitochondrial respiration and iron regulation. DOX is known to bind with iron, contributing to oxidative damage resulting in cardiac and skeletal muscle toxicity. However, the degree to which the toxic side …
Impact Of Aerobic Exercise On Monocyte Subset Receptor Expression And Macrophage Polarization, Anson M. Blanks
Impact Of Aerobic Exercise On Monocyte Subset Receptor Expression And Macrophage Polarization, Anson M. Blanks
Theses and Dissertations
Atherosclerotic cardiovascular disease (CVD) is hallmarked by inflammatory immune activation, particularly by the induction of a response by monocytes. Classical (CD14++CD16-) are anti-inflammatory mediators under homeostatic conditions, while intermediate (CD14++CD16+) and non-classical (CD14LowCD16++) monocytes promote inflammation following activation. Monocyte activation and functionality is dependent upon receptor expression and ligand production by a variety of cells, including monocytes. Alterations in the expression of surface receptors often have a direct impact upon monocyte function, such as the increased pro-inflammatory cytokine production in response to activation that accompanies elevated CD14 expression …
Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.
Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.
Graduate Student Theses, Dissertations, & Professional Papers
Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …
