Cortisol Production In Female Soccer Players, Katelyn Seagraves

ASPIRE 2024

Cortisol is released from the adrenal glands when there is an apparent stressor. Exercise, while beneficial, is seen as stress to the body and incites increased cortisol release. Cortisol is known to increase with exercise, and higher-intensity exercise tends to raise cortisol more compared to lower intensities. However, less is known about interval training and cortisol concentrations.

This review of literature dives into the background of cortisol: how it's produced, what systems it regulates, and differences in production based on gender, stressors, exercise intensity, and duration. This paper identifies some knowledge gaps and links training intensities in soccer to cortisol …

Metabolic Foundations Of Exercise-Induced Cardiac Growth., Kyle Fulghum

Electronic Theses and Dissertations

Regular aerobic exercise promotes physiological cardiac growth, which is an adaptive response thought to enable the heart to meet higher physical demands. Cardiac growth involves coordination of catabolic and anabolic activities to support ATP generation, macromolecule biosynthesis, and myocyte hypertrophy. Although previous studies suggest that exercise-induced reductions in cardiac glycolysis are critical for physiological myocyte hypertrophy, it remains unclear how exercise influences the many interlinked pathways of metabolism that support adaptive remodeling of the heart. In this thesis project, we tested the general hypothesis that aerobic exercise promotes physiological cardiac growth by coordinating myocardial metabolism to promote glucose-supported anabolic pathway …

From Young To Old: The Effects Of Sedentary-Aging And Exercise Interventions On Structural Plasticity Of Lumbar Motor Neurons, Nmj, And Glial Cell Line-Derived Neurotrophic Factor Expression, Alberto Felipe Cintron-Colon

Dissertations

Neuromuscular weakness has been associated with age progression. A possible reason is a disconnection between muscle and neuron, causing components from both the central and peripheral nervous systems to deteriorate. Exercise, however, has beneficial effects for both muscle and nervous tissue, inducing neuroprotection. Neurotrophic factors are powerful regulators of neuronal maintenance and synaptic strength. Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor that has been shown to be a potent survival factor for somatic motor neurons that innervate skeletal muscle.

This study aims to evaluate changes in structural plasticity of motor neurons in the lumbar spinal cord and …

The Effects Of Acute Exercise Intensity On Retrieval-Induced Forgetting, Geoffrey Reliquias

Honors Theses

Previous research has indicated that aspects of cognitive inhibition may be enhanced after engaging in acute exercise. Notably, cognitive inhibition has been theorized as a potential mechanism for a form of active forgetting known as retrieval-induced forgetting (RIF). Given that cognitive inhibition may explain the RIF phenomenon, and is also influenced by exercise, it is plausible that acute exercise may directly influence RIF. To our knowledge, only one study has examined whether acute exercise has an effect on RIF. The findings of that study did not find a statistically significant effect for RIF; however, we believe that the rather small …

Water Intoxication: Current Developments In Hyponatremia, Allison C. Mosmiller

Student Publications

This paper is a review of recent research on the subject of exercise-associated hyponatremia. Hyponatremia is notoriously difficult to diagnose and to treat due to its general symptoms and required specificity in diagnosis in order to assign appropriate treatment. If left untreated, Hyponatremia can result in the development of complications like cerebral edema, seizures, coma, and sometimes death. The pathogenesis of hyponatremia includes multiple proposed mechanisms, including overconsumption of hypotonic fluids, inappropriate release of antidiuretic hormone, inefficiency of fluid filtration by the kidneys, redirection of fluid into intestinal lumen, and activation of the renin-angiotensin-aldosterone system. Signs and symptoms of hyponatremia …
