Purpose: The primary purpose was to examine the effects of ankle taping and bracing on agility, maximum vertical jump (MVJ) height, and vertical power. The secondary purpose was to determine if there were performance differences in training status (athletic vs. non-athletic) between the conditions. Methods: Nineteen participants (Age 20.6±1.5 yr, Height 173.7±11.9 cm, Mass 77.3±18.0 kg) volunteered. Of the 19 participants, 10 (8 male, …

Resistance Exercise, Carotid Artery Stiffness, And Cerebral Blood Flow Pulsatility, W. Lefferts, J. Augustine, K. Heffernan

International Journal of Exercise Science: Conference Proceedings

Lefferts, W., Augustine, J., Heffernan, K., Department of Exercise Science, Syracuse University, Syracuse, NY

Cross-sectional studies have identified arterial stiffness as an important correlate of cerebral blood flow (CBF) pulsatility, an important predictor of cerebrovascular damage. Central artery stiffness increases acutely following a bout of resistance exercise (RE). It has yet to be elucidated whether RE-induced increases in arterial stiffness affect CBF pulsatility. Purpose: To investigate the effects of acute RE on carotid artery stiffness and CBF pulsatility. Methods: 18 healthy men (age 22 ± 1 yr; BMI 23.7 ± 0.5 kg∙m^-2) underwent a) acute RE …

International Journal of Exercise Science: Conference Proceedings

¹Gadomski, S., ¹Cutrufello, P., ²Zavorsky G., & ¹Demkosky, C., ¹University of Scranton, Scranton, PA, ²University of Louisville, Louisville, KY

Citrulline has been proposed as an ergogenic aid because of its role in both ammonia detoxification and nitric oxide production. Watermelon juice has garnered recent media attention due to its citrulline concentration, yet no study has examined watermelon juice and exercise performance. Purpose: Determine the effects of a practical, single, pre-exercise dose of L-citrulline or watermelon juice on maximal oxygen consumption (VO_2max), time to exhaustion (TE), the total maximum number of repetitions completed …

Metabolic Demand And Nutrient Resource In Rowing Ergometer And Treadmill Exercise, E Burns, D. Burns

International Journal of Exercise Science: Conference Proceedings

Burns, E., Burns, D. DeSales University, Center Valley, PA

Purpose: Rowing ergometer exercise differs from treadmill exercise in two ways. Treadmill exercise utilizes primarily the lower extremities and is a load-bearing activity. Rowing is a seated activity and utilizes a much greater muscle mass. This study compared metabolic responses to these two exercise modes at differing submaximal intensities. Methods: Twelve healthy college-age males completed one exercise exposure on a treadmill and one on a rowing ergometer. Metabolic steady state was achieved during each stage of exercise at intensities approximating 4, 6, and 8 MET. Oxygen consumption, respiratory exchange ratio (RER), …

International Journal of Exercise Science: Conference Proceedings

Burket, J., Eubank, T., Reed, C., Sanders, J. Shippensburg University, Shippensburg, PA

Purpose: The purpose of this study was to determine whether music tempo affects squat performance. Methods: A total of eleven healthy college aged subjects (Age range: 18 ~ 22 yrs, Weight: 81.4±12.0 kg, Height: 1.7±0.1 m) volunteered in the study and eight subjects (one female and seven males) completed the study. After obtaining baseline measures, subjects performed heavy barbell squat exercise under three conditions. The three conditions were to perform the squat exercise with load equal to 60% of their body weight until failure while listening to fast …

Glycemic Control Following Nordic Ski Training, W.A. Braun

International Journal of Exercise Science: Conference Proceedings

Braun, W.A. (FACSM), Shippensburg University, Shippensburg PA

Purpose: To study the effects of Nordic ski training on post-exercise blood glucose (BG) clearance. Methods: Twenty-one (male = 10; female =11), competitive college Nordic skiers (age=19.14±1.3 yrs.; body fat %=14.9±6.2) completed two ski training conditions (high intensity: HI; and easy volume: VOL) and one resting control (CON) condition on separate days. At rest on the control day and upon completion of ski training, a 75 g oral glucose tolerance test (OGTT) was administered. BG was measured prior to the OGTT and at 20 min intervals for 80 min of passive rest. Hunger …

Effects Of A High Speed-Low-Resistance Bicycling Intervention In Parkinson’S Disease, M. Bellumori, M. Uygur, C.A. Knight

International Journal of Exercise Science: Conference Proceedings

Bellumori, M., Uygur, M., Knight, C.A. University of Delaware, Newark, DE

Bradykinesia is a symptom of Parkinson’s disease (PD) that substantially decreases mobility while contributing to increased rates of disability and health care costs. Bicycling exercise is a promising strategy that could improve mobility in PD. Purpose: To determine the effects of a six week exercise intervention that uses high speed- low-resistance (HS-LR) stationary recumbent cycling in people with PD. Methods: Pre-exercise tests assessed level of PD severity, physical function, and perceived health. These were again performed following a supervised, 6-week (12 sessions), HS-LR program. Results: Eleven participants (age 62.7 …

Relationships Between Anthropometric And Performance Variables In Youth: Predictors Of Lower-Body Vertical Jump Peak Power, Alexander S. Drusch, Elias M. Carrillo, Jacob Adam Mota, Kendra D. Olinghouse, Matt S. Stock, Marc Lochbaum, Brennan J. Thompson

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

Anthropometric and physical performance measurements are commonly used for identifying specific physical traits in youth. Laboratory-based tests (e.g., linear velocity transducers), while accurate, provide practical limitations due to high costs and technical necessities. Thus, commonly used field tests may be useful alternatives for assessing fitness/performance characteristics of youth. The purpose of this study was to examine the relationships between anthropometric measures and lower-and upper-body power and strength measures; and to assess the predictive ability of these measures for lower-body vertical jump peak power (PP) output in youth. Thirty-nine pre-adolescent (mean±SD, range: age=7.8±1.7, 5-12 years) children volunteered to participate in …

Category: Masters

Advisor / Mentor: Fogt, Donovan ([email protected])

ABSTRACT

Whole body energy expenditure (i.e., RMR) increases during acute cold exposure. Whether this increase in energy expenditure persists in the post-cold term in humans due to non-shivering thermogenesis has not yet been evaluated. Therefore we tested the hypothesis that RMR would be different directly following acute cold exposure. …

Snp-Induced Dilation Following A Short-Term Intraluminal Pressure Increase In Aged Skeletal Muscle Feed Arteries, John W. Seawright, Meredith J. Luttrell, Christopher R. Woodman

International Journal of Exercise Science: Conference Proceedings

A decline in peripheral vascular function occurs with age and is associated with an increased risk for cardiovascular disease. Moderate, aerobic exercise has been documented to improve or reverse the age-related decline in vascular function. The signal(s) associated with exercise responsible for the improvement in vascular function is not known; however, increased intraluminal pressure that occurs during a bout of exercise has been proposed to play an integral role. Previously, we reported that exposure to a short-term increase in intraluminal pressure improves endothelium-dependent vasodilator responses in aged arteries. The purpose of this study was to determine whether pressure treatment enhances …

Fitness A Stronger Exercise Motivator Among United States Female Collegiate Exercise Physiology Students Compared To Czech Republic, Jessica A. Peterson Ms

International Journal of Exercise Science: Conference Proceedings

Motivation is significant in influencing behavior change and maintaining a healthy lifestyle. Physical appearance, weight control, and fitness enhancement are primary motivators for exercise participation and adherence. Exercise knowledge and cultural influences are less established. The purpose of this study was to compare exercise motivators among collegiate female exercise physiology students from the United States (US) and the Czech Republic (CR). US (N=28; age=21.1±2.2) and CR (N=25; age=20.2±1.5) freshman exercise physiology students from Valdosta State University (Valdosta, GA) and Palacký University (Olomouc, CR) volunteered for the study. A secondary analysis was conducted on female participants using body mass index (BMI) …
