The Effects Of Ovarian Hormones And Exercise On Gene Markers Of Cardiac Dysfunction, Anisha S. Patel

Masters Theses

Heart disease is the leading cause of death in women in the United States. Premenopausal women appear to have better cardiac function and lower risk of heart disease compared to male postmenopausal female counterparts. Ovarian hormone loss influences blood pressure homeostasis and causes systemic inflammation, which may result in chronic stress on the heart. Two key physiological changes in cardiac dysfunction are reemergence of the fetal gene pattern and myocardial remodeling. Physical activity has been linked to improved cardiac function. The purpose of this study was to investigate the effects of ovariectomy on early markers of cardiac dysfunction and fibrosis …

The Countering Effects Of Exercise On Stress Reduced Long-Term Potentiation In Mouse Hippocampi, Jacob Trotter, Dr. Jerffrey Edwards

Journal of Undergraduate Research

The hippocampus is an area of the brain that mediates learning and memory by changing the properties of synapses between its neurons. This ability of synapses to change is known as synaptic plasticity. Long-term potentiation (LTP), a long-lasting increase in signal transmission between two neurons, is one of several phenomena underlying synaptic plasticity and is the cellular correlate of memory and learning. Several studies of LTP in mice show that there is a marked impairment of LTP in hippocampal slices taken from rodents exposed to stress. Their data suggests that stress may lead to deficits in learning and memory. In …

The Effects Of Stress And Exercise On Learning And Memory, Teresa Nufer (St. Pierre), Jeffery G. Edwards

Journal of Undergraduate Research

Both stress and exercise have significant physiological effects. Researchers have studied these effects throughout the body, and current evidence suggests that exercise and stress also have profound effects on the brain. While stress decreases brain function, exercise has been show to enhance brain function. Recently, researchers have begun to investigate the effects of stress and exercise on the brain simultaneously, instead of studying the effects individually. Our lab has furthered these studies through the use of electrophysiology and behavioral experiments. Four groups of mice were studied: a control group, a group that experienced a chronic stress protocol, a group that …

Thermoregulatory Dysfunction In Multiple Sclerosis Patients During Moderate Exercise In A Thermoneutral Environment, Mu Huang, Nathan Morris, Ollie Jay, Scott Davis

International Journal of Exercise Science: Conference Proceedings

Impairments in sudomotor function during passive heat stress have been reported in multiple sclerosis (MS), a demyelinating disease of the CNS that disrupts autonomic function. However, little is known regarding exercise induced increases in core body temperature on thermoregulatory mechanisms in MS. Thus, the aim of this study was to test the hypothesis that thermoregulatory function is impaired in MS patients compared to healthy controls (CN) during moderate exercise. Thermoregulatory function in five patients diagnosed with relapsing-remitting MS and five mass-matched healthy controls were compared during a single bout of cycling exercise (fixed workload of 70 Watts) for 30-60 minutes …

Do Elliptical Trainers Accurately Estimate Energy Expenditure?, Kevin Vallecillos, Edith Torres, Alberto Garcia, Kelsey Mclaughlin, Bethany Noack, Jorge Granados

International Journal of Exercise Science: Conference Proceedings

Life Fitness and Precor elliptical exercise trainers are very popular in fitness centers because of the reduced impact on joints as compared to running on a treadmill.
