Sex Differences In Change In Skin Temperature When Exercising In A Hot, Humid Environment, Adam S. Venable, Eric A. Prado, Andrea L. Henning, David W. Hill, Jakob L. Vingren, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

The risk for heat-related illness is increased when exercising in a hot, humid environment. In an effort to protect the athlete, body temperature is measured continuously while exercising in extreme environments. Currently, researchers and laboratory personnel employ the use of mean skin temperature to monitor athlete safety; however, this measurement fails to consider localized changes in temperature that may arise as a function of sex and exercise time. Therefore, the purpose of this study was to examine potential sex differences in the change in skin temperature at 17 different upper body locations while exercising in a hot, humid environment. Young …

Methods To Minimize Confounding Effects Of Hematocrit And Hemoglobin When Using Dried Blood Spots, Eric A. Prado, Adam Venable, Andie Henning, Jakob Vingren, David W. Hill, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Dried blood spots (DBS) are an alternative method of collecting venous blood samples that can be used to measure blood biomarkers. Two confounding factors, hemoglobin and hematocrit, limit the validity of DBS in comparison to the gold standard serum sample. The saturation of biomarkers on DBS filter paper is affected by the sample’s hematocrit and hemoglobin. Also hemoglobin contamination is known to confounder for antibody binding in assay systems. The purpose of this study was two-fold: 1) to evaluate a DBS punching technique designed to limit the effects of hematocrit whilst minimizing sample volume and 2) to evaluate a novel …

Effects Of Obesity On Stability Control Among Young Adults In Responding To A Simulated Slip Induced In Gait, Jaeeun Kim

International Journal of Exercise Science: Conference Proceedings

Falls among older adults present a significant medical, societal, and economic challenge affecting not only the frail or impaired, but the active and vigorous. Falls initiated by slip account for about 25% of all falls among older people. Obesity has been regarded as a significant health problem. It has been reported that obesity causes muscle weakness, abnormal body mass distribution, and postural instability. Dynamic gait stability has been identified as a key factor leading to falls during slip in gait among both young and old adults. Despite the fact that obese individuals suffer higher risk of falls compared to non-obese …

Effects Of Vibration Training On Reducing Risk Of Falls Among Young Adults With Obesity, Jose J. Munoz

International Journal of Exercise Science: Conference Proceedings

Obesity is a major concern around the world. One of the major concerns associated with obesity is that it leads to increased risk of falls. High risk of falls among obese individuals has been related to several factors such as abnormal body mass distribution, muscle weakness, and postural instability. A significant portion of obese individuals are unable or unwilling to comply or manage conventional training regimens requiring high intensity and long duration. Therefore, alternative training methods are in high demand. Controlled whole-body vibration (CWBV) training has been proven to reduce the risk of falls among older adults. No study has …

Visceral Fat Prediction Models According To Age And Gender, Serena Chang

International Journal of Exercise Science: Conference Proceedings

Obesity is the leading risk factor for metabolic syndrome and puts individuals at an increased risk for cardiovascular disease and diabetes.Past studies have shown that visceral adipose tissue (VAT), rather than subcutaneous fat (SF), is a major predictor of these disorders.VAT is the fatty tissue surrounding the vital organs, while SF is the fat found directly beneath the skin. SF’s primary function is to provide energy storage while VAT cells are metabolically active and have been linked to increased insulin resistance, production of triglycerides and low density lipolipids, which contribute to a higher risk of health diseases.Due to lack of …

Executive Function Relationships To Sitting Time And Physical Activity: A Pilot Study, Megan E. Mcclendon, Mark D. Faries, Jessica Thompson, Danielle Cofield

International Journal of Exercise Science: Conference Proceedings

Executive function (EF) refers to the neurocognitive perspective of supervisory abilities to self-regulate during goal-direct behavior. More specifically, the ability to attend to and inhibit dominant responses (i.e. Attention/Inhibition) has been found to moderate the intention and physical activity (PA) relationship, yet does not appear to relate to PA. However, this EF is related to other health behaviors, such as smoking and alcohol consumption (i.e. behaviors to be inhibited). The lack of relationship to PA might be due to it being a behavior that is not to be inhibited, compared to a behavior that should be inhibited (e.g. sitting time). …

C.Elegans As A Diabetes & Ischemia Model: Identification Of Genetic And Cellular Changes That Modulate The Survival Of Hyperglycemia And Oxygen-Deprivation, Anastacia M. Garcia, Mary L. Ladage, Brian K. Mcfarlin, Rajeev K. Azad, Pamela A. Padilla

International Journal of Exercise Science: Conference Proceedings

Diet represents an exogenous influence that often yields colossal effects on an individual’s phenotype, physiology, long-term health and disease risk. The overconsumption of dietary sugars for example, has contributed to significant increases in obesity and type 2 diabetes, health issues that are costly both in terms of dollars and human life. Additionally, individuals with these conditions have compromised oxygen delivery and thus, an increased vulnerability to other oxygen-deprivation related disease states, including cardiovascular disease, ischemic strokes, vascular and coronary diseases and myocardial infarction. While human and other mammalian studies have shown that individuals with type 2 diabetes have a worse …

Consumption Of A High-Fat Meal Alters Post-Prandial Sirt Mrna Expression In Blood Leukocytes, Jill N. Sampson, Andrea L. Henning, Eric A. Prado, Adam Venable, Pamela Padilla, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Introduction. Sirtuins (SIRT) are protein deacetylases, hypothesized to regulate the transcription of various genes involved in the prevention of atherogenesis and diet induced obesity. Previous research from our laboratory has demonstrated that consumption of a single, high-fat meal increases various CVD risk factors for up to 5-h post-prandial. Given the importance of SIRT to metabolic disorders, it is reasonable to speculate that a single, high-fat meal also disrupts SIRT. Methods. The purpose of this study was to determine the effect of a high-fat meal (75% of daily kcals & 80% of daily fat needs), on SIRT mRNA expression in blood …

The Freshman 15: Comparing Change In Weight Of Male And Female Student Athletes During The First Year Of College, Nolan E. Klein, Jimmy Smith

International Journal of Exercise Science: Conference Proceedings

Introduction: Before entering college many students are warned about the “Freshman 15” or the notion that students gain 15 lbs of body weight during their first year of college. Previous studies have shown that though students do gain weight during their first year in college, the gain is less than the fabled 15 lbs. However, less is known about first year weight gain in college athletes. Purpose: This study was done to determine whether male and female student athletes at a small private university gained weight during their first year of college and how much body weight changed during that …

Effects Of Acute Cold Exposure On Plasma Biomarkers Associated With Cardiovascular Disease Risk, Michael A. Levi, Jeremy Garcia, Steven Stelly, Donovan Fogt

International Journal of Exercise Science: Conference Proceedings

Background and Aims: The underlying cause of the majority of the cases of CVD is atherosclerosis, which is a condition initiated and progressed by chronic inflammation and hyperlipidemia. We are interested in evaluating the efficacy of cold-exposure to increase shivering- and non-shivering thermogenesis energy expenditure (RMR) as a non-pharmaceutical weight loss tool analogous to low intensity exercise. Naturally, we are concurrently evaluating the possible effects of cold exposure on risk factors associated with CVD risk. Inflammatory cytokines and lipid mediators are used as biomarkers for CVD risk. This proposed study aims to measure cardiovascular inflammatory and lipid biomarkers to expand …

Gender & Sport Related Differences In Electrocardiogram & Pre-Participation Exams (Ppe) In College Age Athletes, Jacob B. Harp, Bradley Kade, Bryan P. Garcia, Magan Johnson, Jamie M. Cvikel, Jennifer Blevins-Mcnaughton

International Journal of Exercise Science: Conference Proceedings

Background and Purpose: The NCAA requires all college level athletes receive a pre-participation physical exam. However, the pre-participation exams occasionally do not require electrocardiogram screening to help detect cardiac abnormalities. Though electrocardiograms may not be available at all testing’s, using specific markers and finding differences between gender and sport abnormalities could help detect cardiac abnormalities. The purpose of this study was to determine if there were significant differences in resting 12-Lead ECG markers in a group NCAA Div. II collegiate level athletes.

Methods: Four hundred fifty-one college level athlete’s ages 18 to 25 participated in this study. Age, gender, height, …

Effects Of Nutrition Education On Dietary Intake Quality And Nutrition Knowledge In Professional Soccer Players – A Pilot Study, Brittany Wise, Randahl Capurro, Donovan Fogt

International Journal of Exercise Science: Conference Proceedings

Background and Aims: Nutrition is an important factor for optimal performance of professional athletes. Several studies have demonstrated that elite athletes, especially soccer players, don’t eat enough or a high quality diet. Research shows that a diet with 65-70% of calories from carbohydrates, 20-35% calories from fat and approximately 12% of calories from protein out of an approximate 5,000 kcal diet will show improvements in performance of athletes training at high intensities. This pilot study aimed to test the impact of a targeted nutrition education program on dietary intake quality and nutrition knowledge in professional soccer players.

Methods: We initially …
