Changes In Physical Activity And Relationships To Submaximal Exercise Capacity And Cardiac Function During Breast Cancer Therapy, Moriah P. Bellissimo
Changes In Physical Activity And Relationships To Submaximal Exercise Capacity And Cardiac Function During Breast Cancer Therapy, Moriah P. Bellissimo
Theses and Dissertations
Background: Breast cancer (BC) survivors are at high risk for heart failure due to curative cancer therapies. In non-cancer populations, physical activity is a first line treatment for preventing cardiovascular disease. This study examined whether more physical activity was associated with better submaximal exercise capacity and cardiac function during the first three months of cancer therapy.
Methods: Participants included 223 women with stage I-III BC before therapy and after three months of undergoing treatment and 126 controls. Leisure time physical activity was reported using the Godin Sheppard leisure time exercise questionnaire. Cardiac function was assessed by cardiac magnetic resonance, and …

Low physical activity is associated with heart failure with preserved ejection fraction (HFpEF). Step-counts, a measure of physical activity, can be measured via accelerometry. To date, few studies have examined validity of accelerometer-derived step-counts in the adults with HFpEF.
PURPOSE To assess criterion validity of the Actigraph GT9X accelerometer step-count function in adults with HFpEF via ankle, waist, and wrist placement, compared with manually counted, directly observed steps.
METHODS Six adults with HFpEF (age: 57.2 ± 9.4 y; African American: 50%; females: 100%) completed a cardiopulmonary exercise test (CPET) on a treadmill while wearing synchronized GT9X accelerometers on the ankle, …
An Evaluation Of Induced Shear Stress On Endothelial Cellular Adhesion Molecules, Edward B. Crabb
An Evaluation Of Induced Shear Stress On Endothelial Cellular Adhesion Molecules, Edward B. Crabb
Theses and Dissertations
The pathophysiology of atherosclerotic cardiovascular disease (CVD) is highlighted by vascular dysfunction and low-grade vascular inflammation. Furthermore, the site-specific distribution of atherosclerosis throughout the arterial vasculature is primarily determined by local hemodynamic force. Therefore, this dissertation outlines three experiments designed to investigate the role of acute mental and physical (i.e., aerobic exercise), and vascular wall shear stress (SS) on the inflammatory aspects of atherosclerosis. Chapter 2 examines the effect of acute laboratory-induced mental stress on intracellular pro-inflammatory signaling pathways in peripheral blood mononuclear cells. Chapter 3 investigates the impact of acute laboratory-induced mental stress and maximal aerobic exercise on the …
The Antioxidant Potential Of The Mediterranean Diet In Patients At High Cardiovascular Risk: An In-Depth Review Of The Predimed, Hayley E. Billingsley, Salvatore Carbone
The Antioxidant Potential Of The Mediterranean Diet In Patients At High Cardiovascular Risk: An In-Depth Review Of The Predimed, Hayley E. Billingsley, Salvatore Carbone
Kinesiology and Health Sciences Publications
Cardiovascular disease (CVD) is the leading global cause of death. Diet is known to be important in the prevention of CVD. The PREDIMED trial tested a relatively low-fat diet versus a high-fat Mediterranean diet (MedDiet) for the primary prevention of CVD. The resulting reduction of the CV composite outcome resulted in a paradigm shift in CV nutrition. Though many dietary factors likely contributed to this effect, this review focuses on the influence of the MedDiet on endogenous antioxidant systems and the effect of dietary polyphenols. Subgroup analysis of the PREDIMED trial revealed increased endogenous antioxidant and decreased pro-oxidant activity in …
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 …
Lps-Induced Inos Mrna And The Pro-Apoptotic Signaling Pathway In Leukocytes Of Fit And Unfit Males, Tiffany M. Zuniga
Lps-Induced Inos Mrna And The Pro-Apoptotic Signaling Pathway In Leukocytes Of Fit And Unfit Males, Tiffany M. Zuniga
Theses and Dissertations
Overexpression of the enzyme iNOS induces apoptotic cellular death by increasing indices of pro-inflammation and oxidative stress. Aerobic physical activity has been known to have anti- inflammatory benefits and reduce oxidative stress. Purpose: Therefore, this study aimed to examine the impact of aerobic fitness on LPS-induced iNOS mRNA expression and the relationship of this expression with indices of oxidative stress, pro-inflammation and apoptosis in isolated leukocytes. Methods: Whole blood samples from aerobically fit and unfit males were stimulated with and without LPS. Thereafter, iNOS mRNA expression and MDA, TNF-α and p53 concentrations were analyzed. Results: iNOS mRNA expression levels following …

PURPOSE: Running-related injuries are most often single-sided and are partially attributed to lower limb movement and loading asymmetries.1 Gluteus Medius (GM) plays a significant role in lower limb alignment, especially in the frontal and transverse planes by its influence on the pelvis and the femur.2 Female runners are more prone to GM weakness which has been proposed to be a risk factor for overuse injuries.3 These strength deficits contribute to abnormal lower limb kinematics and kinetics during dynamic tasks like running and jumping.4 These changes include an increase in peak hip adduction angle (HA), hip internal …

Obesity is defined as the excess accumulation of intra-abdominal body fat, resulting in a state of chronic, low-grade proinflammation that can directly contribute to the development of insulin resistance. Pentraxin 3 (PTX3) is an acute-phase protein that is expressed by a variety of tissue and cell sources and provides an anti-inflammatory property to downregulate the production of proinflammatory cytokines, in particular interleukin-1 beta and tumor necrosis factor alpha. Although PTX3 may therapeutically aid in altering the proinflammatory milieu in obese individuals, and despite elevated expression of PTX3 mRNA observed in adipose tissue, the circulating level of PTX3 is reduced with …

Background: Obesity affects over one-third of older adults in the United States. Both aging and obesity contribute to an increased risk for chronic disease, early mortality, and additional health care utilization. Obesity rates are higher in rural areas than in urban areas, although findings are mixed. The objectives of this study are to assess potential nonlinearity in the association between rurality and obesity, and to evaluate the potential for socioeconomic status and geographic area to moderate the associations between rurality and obesity.
Methods: Using a representative sample of adults aged 65 and above from the Behavioral Risk Factor Surveillance System, …

Heart failure with preserved ejection fraction (HFpEF) is associated with obesity and, indirectly, with unhealthy diet. The role of dietary components in HFpEF is, however, largely unknown. In this study, the authors showed that in obese HFpEF patients, consumption of unsaturated fatty acids (UFA), was associated with better cardiorespiratory fitness, and UFA consumption correlated with better diastolic function and with greater fat-free mass. Similarly, mice fed with a high-fat diet rich in UFA and low in sugars had preserved myocardial function and reduced weight gain. Randomized clinical trials increasing dietary UFA consumption and reducing sugar consumption are warranted to confirm …

Obesity-related oxidative stress, the imbalance between pro-oxidants and antioxidants (e.g., nitric oxide), has been linked to metabolic and cardiovascular disease, including endothelial dysfunction and atherosclerosis. Reactive oxygen species (ROS) are essential for physiological functions including gene expression, cellular growth, infection defense, and modulating endothelial function. However, elevated ROS and/or diminished antioxidant capacity leading to oxidative stress can lead to dysfunction. Physical activity also results in an acute state of oxidative stress. However, it is likely that chronic physical activity provides a stimulus for favorable oxidative adaptations and enhanced physiological performance and physical health, although distinct responses between aerobic and anaerobic …

Kinesiology and Health Sciences Publications
Spinal cord injury (SCI) leads to serious body composition adaptations characterized by increasing whole body fat mass and decreased soft tissue lean mass (LM). These adaptations in body composition may lead to several cardio-metabolic disorders that reduce the quality of life, increase patients’ and caregivers’ burden and eventually leads to mortality. Exercise, an appropriate dietary regimen, and an active lifestyle may alleviate several of the negative effects on body composition after a SCI. Today however, there is no established consensus on the recommended dose, frequency or type of exercise to ameliorate several of the body composition sequelae after an acute …
Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish
Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish
Theses and Dissertations
High intensity exercise is believed to yield greater results on health and human performance than moderate intensity exercise. Extensive research indicates that not only do high-intensity interval training (HIT) and sprint interval training (SIT) produce significant improvements in cardiovascular fitness and disease, they may be more effective at improving long-term metabolic function, including insulin sensitivity (Si), by producing more mitochondria. Moreover, compliance rates for HIT and SIT participation are reported to be the same or better than traditional moderate intensity exercise. Because lack of time is often cited as major hindrance to exercise participation, SIT is also seen as a …
