Il-15 Activates The Jak3/Stat3 Signaling Pathway To Mediate Glucose Uptake In Skeletal Muscle Cells, James E. Krolopp, Shantaé M. Thornton, Marcia J. Abbott

Health Sciences and Kinesiology Faculty Articles

Myokines are specialized cytokines that are secreted from skeletal muscle (SKM) in response to metabolic stimuli, such as exercise. Interleukin-15 (IL-15) is a myokine with potential to reduce obesity and increase lean mass through induction of metabolic processes. It has been previously shown that IL-15 acts to increase glucose uptake in SKM cells. However, the downstream signals orchestrating the link between IL-15 signaling and glucose uptake have not been fully explored. Here we employed the mouse SKM C2C12 cell line to examine potential downstream targets of IL-15-induced alterations in glucose uptake. Following differentiation, C2C12 cells were treated overnight with 100 …

The Hemostatic Effects Of Acute Exposure To Colored Cornstarch Powder During A 5k Run, Robert C. Allsbrook

Senior Honors Projects, 2010-2019

PURPOSE: To examine the acute hemostatic effects of particulate matter (PM) in the form of colored corn starch powder during a 5 kilometer race. METHODS: 10 recreationally active adults completed two 5k runs, one with color and one without color. 10 mL blood samples were taken 6 hours prior to the trial and immediately following the trial. PAI-1 activity, FVIII antigen, and tPA activity were measured using an ELISA. RESULTS: No significant main effects or interaction effects (P<0.05) were observed among any of the variables although a trend (P = 0.082) was observed for increased PAI-1 activity during exercise in the color condition. CONCLUSIONS: There is a trend towards increased PAI-1 activity levels during exercise during color runs that could be due to increased inflammation. Furthermore, the lack of increased FVIII:ag and tPA activity suggests that the intensity of the exercise may not have been adequate and further research should be conducted in this area.

Daily Variability Of Body Weight And Hydration Markers In Free Living Men And Women, Lynndee Grace Summers

Graduate Theses and Dissertations

Body weight and hydration markers change greatly during strenuous exercise, especially in the heat. However, in a non-athletic population, changes in body weight and hydration markers may not be so obvious. It is important to classify the normal fluctuation of these measurements for future studies in order to delineate when an intervention results in a change outside of what can be expected during normal daily living. PURPOSE: The purpose of this study was to describe the normal fluctuations in body weight and urine hydration markers over the course of 29 days. METHODS: One-hundred two male and female participants, ranging from …

The Differences In Time To Stability, Foot Muscle Size, And Toe Flexor Strength Between Cheerleaders And Gymnasts, Kelsey Renee Garner

Theses and Dissertations

Context: There has been recent speculation that the intrinsic muscles of the foot may play a larger role in lower extremity control and injury than previously believed. Multiple studies have shown that certain intrinsic muscles increase in size and strength after transitioning to minimalist shoe running, theoretically decreasing injury risk. There are currently no studies that examine the effect that training barefoot has in other athletic populations. Objective: Our purpose was to compare the intrinsic and extrinsic foot muscle size and strength in gymnasts (who predominantly train barefoot) and cheerleaders (who predominantly train shod). Another purpose was to measure time …

Barriers, Motivations, And Preferences For Physical Activity Among Female African American Older Adults, Neha P. Gothe, Bradley J. Kendall

Kinesiology, Health and Sport Studies

According to the Centers for Disease Control and Prevention, less than 11% of adults more than the age of 65 meet the 2008 Physical Activity Guidelines for Americans. Among minority populations, only 5% of non-Hispanic Black older adults met the guidelines. Given our limited understanding of psychosocial and environmental factors that affect physical activity participation in these groups, the purpose of our focus groups was to investigate barriers, motivators, and preferences of physical activity for community-dwelling African American older adults. Three focus groups were conducted with female African American older adults (N = 20). Questions posed to each focus group …

Putting The Athletic Back In The Trainer, Shelby L. Davis

Posters-at-the-Capitol

Athletic Training Students are taught about the benefits of physical activity and how to create specific exercise programs to maintain overall wellness. Although athletic training students have knowledge about the positive effects of physical activity, they continually score lower on activity level scales when compared with the average college student. A rigorous course schedule and long clinical hours seem to be a common factor that play into the poor health habits of the athletic training student. Therefore, the purpose of this study is to determine the variables that negatively affect the exercise habits of undergraduate athletic training students.

Students from …

Differences In Depression, Anxiety, And Life Satisfaction Between Intercollegiate Athletes, Intramural Participants, And Non-Athletes, Megan Wilson

Masters Theses & Specialist Projects

It is widely supported that participation in athletics is positively correlated with increased overall health. However, some research indicates that participation in increased levels of competition is positively correlated with higher levels of depression and anxiety. This means, that if compared, athletes competing nationally or internationally would report higher levels of both depression and anxiety than athletes competing at the intercollegiate level. Research indicates that this could be caused by increased amounts of pressure, personal cost, and expectation.

This study examines potential differences between intercollegiate, intramural, and non-athletes in these areas on a college campus. The first hypothesis is that …

ETSU Faculty Works

The effects of short-term resistance training on performance and health variables associated with prolonged sedentary lifestyle and metabolic syndrome (MS) were investigated. Resistance training may alter a number of health-related, physiological, and performance variables. As a result, resistance training can be used as a valuable tool in ameliorating the effects of a sedentary lifestyle including those associated with MS. Nineteen previously sedentary subjects (10 with MS and 9 with nonmetabolic syndrome [NMS]) underwent 8 weeks of supervised resistance training. Maximum strength was measured using an isometric midthigh pull and resulting force-time curve. Vertical jump height (JH) and power were measured …

Biomechanical Analysis Of Gait Termination In 11–17 Year Old Youth At Preferred And Fast Walking Speeds, Sarah T. Ridge, John Henley, Kurt Manal, Freeman Miller, James G. Richards

Faculty Publications

In populations where walking and/or stopping can be difficult, such as in children with cerebral palsy, the ability to quickly stop walking may be beyond the child’s capabilities. Gait termination may be improved with physical therapy. However, without a greater understanding of the mechanical requirements of this skill, treatment planning is difficult. The purpose of this study was to understand how healthy children successfully terminate gait in one step when walking quickly, which can be challenging even for healthy children. Lower extremity kinematic and kinetic data were collected from 15 youth as they performed walking, planned, and unplanned stopping tasks. …

The Aging Neuromuscular System And Motor Performance, Sandra K. Hunter, Hugo M. Pereira, Kevin Keenan

Exercise Science Faculty Research and Publications

Age-related changes in the basic functional unit of the neuromuscular system, the motor unit, and its neural inputs have a profound effect on motor function, especially among the expanding number of old (older than ∼60 yr) and very old (older than ∼80 yr) adults. This review presents evidence that age-related changes in motor unit morphology and properties lead to impaired motor performance that includes 1) reduced maximal strength and power, slower contractile velocity, and increased fatigability; and 2) increased variability during and between motor tasks, including decreased force steadiness and increased variability of contraction velocity and torque over …

Sagittal Plane Gait Kinematics In Individuals With Chronic Ankle Instability, Matthew C. Hoch, David R. Mullineaux, Kyoungkyu Jeon, Patrick O. Mckeon

Rehabilitation Sciences Faculty Publications

Single joint kinematic alterations have been identified during gait in those with chronic ankle instability (CAI). The purpose of this study was to compare sagittal plane hip, knee, and ankle kinematics during walking in participants with and without CAI. Twelve individuals with CAI and 12 healthy individuals walked on a treadmill at 1.5 m/s. Three-dimensional kinematics were analyzed using mean ensemble curves and independent t tests. Participants with CAI demonstrated less lower extremity flexion during the absorption phase of stance and the limb placement phase of swing, which may have implications for limb placement at initial contact.

CrossFit participants (N = 206; Mage = 37.6 years), majority Caucasian (76%), females (58%), who reported attending three (n = 91; 44.2%) and five (n = 78; 37.9%) CrossFit sessions per week completed online surveys …

Short-Interval Cortical Inhibition And Intracortical Facilitation During Submaximal Voluntary Contractions Changes With Fatigue, Sandra K. Hunter, Chris J. Mcneil, Jane E. Butler, Simon C. Gandevia, Janet L. Taylor

Exercise Science Faculty Research and Publications

This study determined whether short-interval intracortical inhibition (SICI) and intracortical facilitation (ICF) change during a sustained submaximal isometric contraction. On 2 days, 12 participants (6 men, 6 women) performed brief (7-s) elbow flexor contractions before and after a 10-min fatiguing contraction; all contractions were performed at the level of integrated electromyographic activity (EMG) which produced 25 % maximal unfatigued torque. During the brief 7-s and 10-min submaximal contractions, single (test) and paired (conditioning–test) transcranial magnetic stimuli were applied over the motor cortex (5 s apart) to elicit motor-evoked potentials (MEPs) in biceps brachii. SICI and ICF were elicited on separate …

Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd

Mahurin Honors College Capstone Experience/Thesis Projects

The skeletal muscle of obese individuals exhibits a depressed ability to metabolize fats. Exercise training is thought to rescue this dampened ability to metabolize fats; mediated by a coordinated increase in the expression of a network of genes that regulate metabolism and fuel utilization. The purpose of this study is to determine the exercise-induced regulation of metabolically important genes in lean and obese individuals. Muscle biopsies (one pre-exercise/baseline and one immediately post-exercise) were obtained from 4 lean (BF% 24.4 ± 5.5; 23.5 yrs ± 1.9) and 13 obese (BF% 39.7 ± 2.4; 26.1 yrs ± 2.3), age-matched, relatively young subjects, …
