Exploring Positive Body Image And Motives For Exercise As Predictors Of Intuitive Exercise And Exercise Behavior Among Women, Natalie Michelle Ramsey

Theses and Dissertations

Purpose: To explore three facets of positive body image and motives for exercise as predictors of women’s intuitive exercise and exercise behavior.

Scientific significance: Positive body image has been associated with health-promoting behaviors such as utilizing sun protection techniques and intuitive eating. Despite these findings and the known benefits of exercise, there are no known published studies exploring if positive body image and exercise motivation predict intuitive exercise and exercise behavior in women. Understanding these relationships could facilitate the design of interventions targeting improvements in both psychological well-being and exercise behavior.

Methodology: This cross-sectional study included 391 women (18-91 years; …

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

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 (CD14^LowCD16⁺⁺) 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 …

The Effects Of Exercise Mode And Intensity On Energy Expenditure During And After Exercise In Resistance Trained Males, George Lewis Grieve

Theses and Dissertations

Purpose: The purpose of this study was to examine the effects of exercise mode and intensity on energy expenditure (EE) during and after five time-matched aerobic and resistance exercise protocols in resistance trained males.

Methods: 14 resistance trained males (mean ± SD; age = 24.2 ± 4.0 yr; body mass = 84.7 ± 13.3 kg; height = 181.2 ± 8.8 cm; and body fat = 15.9 ± 4.6%) completed five separate protocols: continuous aerobic (continuous), high intensity interval aerobic (HIIT), strength endurance (2x20), traditional resistance (3x10), and high intensity resistance (4x6). EE was measured before, during, immediately post (0-30 minutes), …
