Shokraeifard, Heidi L. Cope, Albert H. Olivencia-Yurvati, Rebecca L. Cunningham, Michael L. Smith, Steven A. Romero

International Journal of Exercise Science: Conference Proceedings

The pressor response induced by a voluntary hypoxic apnea is exaggerated in individuals with obstructive sleep apnea and is strongly correlated to sympathetic overactivity. Acute heat exposure alters neural control of blood pressure, but its effect on the pressor response to a voluntary hypoxic apnea has never been explored. PURPOSE: To test the hypothesis that acute heat exposure attenuates the pressor response to a voluntary hypoxic apnea, and thereby manifest as a form of physiological cross-tolerance. METHODS: Eight adults (3 females, 26 ± 2 yrs) were exposed to passive heat stress (water perfused suit) sufficient to increase body core temperature …

Vertical Jump Performance As A Discriminator Of Playing Ability In Collegiate Female Soccer Players, William N. Riley, Kazuma Akehi, Maxwell S. Rowley, Ahalee C. Farrow, Ty B. Palmer

International Journal of Exercise Science: Conference Proceedings

Previous studies have assessed the importance of physical characteristics to soccer playing ability by comparing performance-based outcomes between starters and non-starters. Starters are often considered the most skilled players on the team. These players get more playing time than non-starters and have been shown to achieve higher performance outcomes on intermittent fitness tests. However, it remains unclear whether starters can achieve higher performance outcomes on a countermovement vertical jump. PURPOSE: The purpose of this study was to investigate the efficacy of countermovement vertical jump height and peak power to discriminate between starters and non-starters in collegiate female soccer.

Hypoxic Preconditioning Attenuates Ischemia-Reperfusion Injury In Older Adults, Sten Stray-Gundersen, Sahar D. Massoudian, Frank Wojan, Hirofumi Tanaka, Sophie Lalande

International Journal of Exercise Science: Conference Proceedings

Sudden restoration of blood flow to an ischemic vessel paradoxically damages endothelial cells. In young healthy adults, ischemic preconditioning, caused by repeated periods of brief ischemia induced by local cuff inflation prior to reperfusion, attenuates endothelial dysfunction following an ischemia-reperfusion injury. However, ischemic preconditioning does not consistently protect against ischemia-reperfusion injury in older adults. Intermittent systemic hypoxemia, induced via brief bouts of breathing low levels of oxygen, attenuates endothelial dysfunction following an ischemia-reperfusion injury in young adults. PURPOSE: To determine whether intermittent hypoxia protects against ischemia-reperfusion injury in older adults. METHODS: Twelve older adults (5 women, age: 57 …

Cardiorespiratory Coordination Among Intermediate And Novice Female Collegiate Rowers, Zoey Jackson, Michelle Etchebaster, Paula Gutiérrez, Gemma Hernández, Sergi G. Retortillo, Zacharias Papadakis

International Journal of Exercise Science: Conference Proceedings

Elite rowers present high levels of cardiorespiratory performance. Rowers’ on-water performance can be predicted by a cardiopulmonary exercise test (CPET) and related measured parameters such as maximum oxygen uptake test (VO2max), ventilation (VE), heart rate (HR), expired fraction of oxygen (FeO2) and carbon dioxide (FeCO2). However, such testing provides little information about the non-linear dynamic interactions during rowing and the qualitative synergetic reconfigurations between cardiovascular and respiratory systems to adjust to the individual rowing performance. Cardiorespiratory coordination (CRC) has been proposed as a method to measure the co-variation among cardiorespiratory variables during a CPET. PURPOSE: To measure and compare …
