Cortisol Production In Female Soccer Players, Katelyn Seagraves

Honors Projects

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 …

The Accuracy Of Recreational Athletes In Self Detecting Ventilation Threshold During A Maximal Exercise Test, Andrew Biegner

Williams Honors College, Honors Research Projects

INTRODUCTION: Ventilatory threshold (VT) is where minute ventilation (VE) increases nonlinearly with increasing exercise intensity. Prior studies have shown that subjects can recognize VT by changes in breathing during exercise. Teaching recreational athletes to use VT as a training method could result in better quality training. PURPOSE: Determine if recreational athletes can accurately perceive changes in ventilation associated with VT during maximal exercise testing. METHODS: Subjects were recruited (n=20, age= 20.5 ± 1.7 yrs.) to participate in the study. Subjects performed a modified maximal treadmill protocol with gas analysis. Subjects indicated when they noticed a considerable change …

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 …

Parkinson's Disease And Exercise: Steps Into A Hopeful Future, Jacob Barker

Spring Showcase for Research and Creative Inquiry

In the world of medicine and disease interventions, exercise is too often underlooked as a viable form of treatment or complementary treatment to medication. This is especially true with Parkinson’s Disease, a disease that attacks the basal ganglia of the brain and impairs neuromuscular function. In my analysis, I read a perspective from a PD patient, Gerry Hill, who has struggled with the disease himself and how he used physical activity to aid in his battle with the disease for both physical and psychological aid. Additionally, I performed research to understand how exercise benefits function within the brain. Aerobic exercise, …

Role Of Neuronal Nitric Oxide Synthase On Cardiovascular Functions In Physiological And Pathophysiological States, Ahmmed Ally, Isabella Powell, Minora M. Ally, Kevin Chaitoff, Surya M. Nauli

Pharmacy Faculty Articles and Research

This review describes and summarizes the role of neuronal nitric oxide synthase (nNOS) on the central nervous system, particularly on brain regions such as the ventrolateral medulla (VLM) and the periaqueductal gray matter (PAG), and on blood vessels and the heart that are involved in the regulation and control of the cardiovascular system (CVS). Furthermore, we shall also review the functional aspects of nNOS during several physiological, pathophysiological, and clinical conditions such as exercise, pain, cerebral vascular accidents or stroke and hypertension. For example, during stroke, a cascade of molecular, neurochemical, and cellular changes occur that affect the nervous system …

Modulation Of Parasympathetic Reactivation Post-Exercise Via Slow Breathing, Brent Burg

CSB and SJU Distinguished Thesis

During exercise sympathetic nervous activity increases and parasympathetic nervous activity decreases to fuel energy demands. Heart rate variability (HRV) indicates activity of the autonomic nervous system and the balance of its two branches. Slow breathing (SB) (6 breaths/minute) increases parasympathetic activity both spontaneously during practice and at rest after long-term practice. Thus, SB may increase parasympathetic activity after exercise. PURPOSE: This study aimed to determine whether post-exercise SB increases parasympathetic activity as measured by HRV. METHODS: Ten recreationally active college aged males (21 +/-1 years old) completed the study. A VO2max test was used to determine 70% of VO2max for …

Spinal Cord Injury Induced Cardiac Decline And The Limitations Of Exercise., Kathryn Michele Deveau

Electronic Theses and Dissertations

There is a general consensus that the level and the severity of spinal cord injury (SCI) impacts chronic cardiac abnormalities such that high thoracic and cervical SCI are the most severely affected. Furthermore, the extreme degree of immobility/inactivity experienced by the persons with SCI has implications on cardiac decline. Yet it has been difficult to separate the relative contributions of the decentralized autonomic nervous system (ANS) and the immediate and profound inactivity to chronic cardiac abnormalities. As such, this body of work sought to characterize a contusion SCI that results in persistent CV dysfunction. Echocardiography, Dobutamine stress echocardiography and pressure …

The Physiology And Psychology Of Exercise And Parkinson's Disease, Jess Gibson

Senior Honors Theses

Parkinson’s disease is one of the most common degenerative neurological disorders and is currently lacking a cure. While physicians have long debated over the best treatment for Parkinson’s symptoms, treatments such as oral medication and deep brain stimulation have not yet shown to be a permanent solution to the disease. Recently, exercise has emerged as a contender in the fight against Parkinson’s and physicians and physiotherapists have been investigating the benefits of prescribing exercise programs to patients in an effort to slow progression of Parkinson’s symptoms. The following presents an analysis of the effects of exercise on Parkinson’s symptoms and …
