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 …

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 …

The Onset Of Exercise-Associated Hyponatremia And Individual Differences In Inappropriate Arginine Vasopressin Excretion: A Review Of Proposed Mechanisms, Michelle Stehman, Stephen A. Maris

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 10, 2021. Exercise-associated hyponatremia (EAH) has been reported to develop during endurance events such as triathlons and marathons. As these events become more popular, the incidence of developing EAH also increases. The development of EAH is commonly associated with the overconsumption of hypotonic fluids such as water and tends to be more prevalent in females. There is also evidence to suggest the inappropriate secretion of arginine vasopressin (AVP) leading to water retention may predispose an individual for developing EAH, especially when coupled with the overconsumption of fluids. Recent research …

Effects Of A Strength Training Intervention And Quality Of Life: Case Study On A Sedentary Adult Female, Lucas Frazier

Williams Honors College, Honors Research Projects

The purpose of the project is to evaluate physiological and quality of life changes in a

sedentary, senior-aged (55 or older) female using a six-week strength training

intervention. This case study will instruct how to perform a push-pull-legs split

routine by going to the gym three times per week. Prior to the six week intervention,

both quantitative and qualitative variables will be collected to assess baseline data,

including the subject’s resting heart rate, resting blood pressure, grip strength, one-

repetition maximum on seven whole body exercises (dumbbell bicep curl, tricep

pushdown, barbell bench press, wide-grip lat pull-down, seated dumbbell press, …

The Effects Of Home-Based Pilates In Healthy College-Age Females, Betsy Donahoe-Fillmore, Mary Fisher, C. Brahler

C. Jayne Brahler

Objectives: To quantify and determine the effects of Pilates on core endurance, hamstring flexibility, balance, body composition/mass and perceived stress level in healthy college age females.

Study Design: Randomized controlled trial design.

Background: Emerging research on the Pilates technique is inconclusive regarding benefits to core endurance, flexibility, balance, body mass, and perceived stress.

Methods and Measures: Female college students (n=57; 18-35 years old) were randomly assigned to a Pilates group, who exercised at home with a DVD, or a control group who did not engage in Pilates practice. Core endurance, hamstring flexibility, balance, body composition and stress measurements were taken …

Vascular Regulation Via Kir Channels And Na+ /K+-Atpase, Anne R. Crecelius, Frank A. Dinenno

Health and Sport Science Faculty Publications

Despite the longstanding knowledge that blood flow increases in proportion to metabolic activity of skeletal muscle, the underlying mechanisms that govern this response have only recently been identified.¹ Given the role of endothelial cells in mediating exercise hyperemia,² interest has been focused on endothelium-derived vasodilation occurring via the synthesis of nitric oxide (NO) and vasodilating prostaglandins (PGs; i.e. prostacyclin) or endothelium- derived hyperpolarization. A number of studies performed in humans have established a minimal-to-modest role for NO and PGs during mild- and moderate- intensity exercise. In animal preparations, prevention of hyperpolarization attenuates contraction-induced hyperemia; however, performing similar studies …

The Effect Of Shear Stress, Potassium, And Adenosine On Α-1 Adrenergic Vasoconstriction Of Rat Soleus Feed Arteries, Tanner J. Heckle, Jeffrey Jasperse

Featured Research

During exercise, blood flow increases to the working skeletal muscle primarily because of dilation of the arteries and arterioles feeding the muscle. Sympathetic nerve activity also increases during exercise, augmenting the release of the neurotransmitter norepinephrine (NE) at the arterial wall and into the blood. NE acts to constrict blood vessels; however, arteries and arterioles within contracting skeletal muscle dilate despite the increased NE present. This has led to the concept of functional sympatholysis (4), the idea that a chemical released from contracting skeletal muscle interferes with NE signaling. NE acts by binding to adrenergic (alpha and beta) receptors, and …
