Differential Contribution Of Cardiac And Peripheral Blood Flow To Metaboreceptor-Mediated Pressor Responses In Autism Spectrum Disorder, Matthew Pizano Gomez, Gabriel B. Carlota, Stephanie S. Wang, Areum K. Jensen

International Journal of Exercise Science: Conference Proceedings

Young adults with Autism Spectrum Disorder (ASD) experience a higher prevalence of hypertension than the general population. Abnormal blood pressure (BP) response to acute exercise is seen in hypertension. BP response evoked during exercise is the outcome of a central interaction between neural inputs such as the exercise pressor reflex. However, it is unclear if this neurocardiovascular interaction is altered differently to regulate BP during exercise in ASD. PURPOSE: To determine whether contributions of cardiac and peripheral blood flow to metaboreceptor-mediated pressor responses are different during exercise in ASD. METHODS: 21 young adults with and without ASD completed the study. …

Examining Stroke Volume Changes During Exercise In Healthy Young Adults, Thomas Clark, Anthony Ciccone, Zane Evans, Keslee Stephenson, Chandler Rose, Carlos Goff, Shane Draper, Nicolas Clark

International Journal of Exercise Science: Conference Proceedings

Cardiac output is determined by the combination of heart rate and stroke volume. While heart rate is primarily influenced by cardiac autonomic input, stroke volume's behavior is more intricate due to the interplay between myocardial response to stretch (Frank-Starling law) and adrenergic changes in contractility. No consensus exist on its behavior during exercise despite extensive data. PURPOSE: The aim of this study was to assess how normalized stroke volume scores (SV) change in young, healthy adult males during a graded exercise test to exhaustion (GXT). METHODS: Participants (n=20; age=22.9±2.4; BMI=23.7±2.4) were instructed to abstain from engaging in vigorous …

Validation Of The Work Capacity Test For Wildland Firefighters, Cassandra Mcfarland, Zachary Hofheins, Janna Thompson, Lexi Sorensen, Andrew Creer, Shane Draper

International Journal of Exercise Science: Conference Proceedings

Much of the reported Wildland Firefighter (WLFF) data use prediction equations which tend to underestimate oxygen consumption (VO2) during load carriage. As a result, the reported metabolic and oxygen consumption data values may actually be higher creating a larger gap between the US Forest Service arduous pack test (APT) and true occupational demand. The reported data regarding the energy cost upon which the APT has been based (22.5 mL/kg/min of oxygen) has overwhelmingly been tested in current WLFF with few participants. However, no studies have recently examined the current energy expenditure of men and women who want to qualify to …
