Evaluation And Validity Of A Predictive Equation For Measuring Core Temperature During Exercise In Heat Stress, Robert J. Castro, Alexander J. Gonsalves, Edgar B. Doolan, Jochen Kressler
International Journal of Exercise Science: Conference Proceedings
Exercising in the heat is very common yet can pose significant health risks such as heat exhaustion and heat stroke when core temperature exceeds 38°C and 40°C, respectively. However, current methods of core temperature measurement are invasive and impractical. Recent research indicates that core temperature can be predicted with two non-invasive inputs, heart rate (HR) and skin temperature. PURPOSE: The objective of this study was to assess the validity and reliability of this predictive equation against the direct measurement of core temperature. METHODS: Participants (n = 11) cycled in an environmental chamber (40°C, 40% humidity) at 75% …
Relative Contribution Of Cardiac And Peripheral Blood Flow To Blood Pressure In Humans: The Role Of Metaboreceptors, Gabriel B. Carlota, Matthew Pizano, Stephanie S. Wang, Areum K. Jensen
Relative Contribution Of Cardiac And Peripheral Blood Flow To Blood Pressure In Humans: The Role Of Metaboreceptors, Gabriel B. Carlota, Matthew Pizano, Stephanie S. Wang, Areum K. Jensen
International Journal of Exercise Science: Conference Proceedings
The autonomic nervous system plays an essential role during exercise by adjusting cardiac output (CO) and redistribution of peripheral blood flows. One primary mechanism responsible for such alterations is the exercise pressor reflex (EPR), a feedback mechanism from contracting muscles via mechano- and metabo-receptor activation. The EPR adjusts the circulation by evoking reflex increases in sympathetic outflow to the heart and the vasculature, eventually increasing blood pressure (BP) during exercise. Previous studies suggested that relative contribution of cardiac and peripheral blood flow to regulate BP may depend on various factors (e.g., sex, health status). Thus, we thought to investigate if …

The Neglected Category Of Sub-Elite Athletes In Ironman Triathlon, Derek Buesgens, Caio Sousa
The Neglected Category Of Sub-Elite Athletes In Ironman Triathlon, Derek Buesgens, Caio Sousa
International Journal of Exercise Science: Conference Proceedings
Physical tests and training programs are tailored considering many factors, including the athletic level (i.e., amateur vs. professional, also known as age-group vs. elite). Ironman triathlon (IM) is a long-distance endurance event that thousands of athletes participate in around the world. However, the conventional division of athletes between age-groupers and elites neglect a group of amateur athletes who perform similarly to elite athletes. The spotlight on a new category of “sub-elite” athletes highlights the importance of new physical assessment protocols for a group largely underestimated as an amateur but overrated as an elite athlete. PURPOSE: The goal of this …

Relationship Of Reacstick® Inhibition Accuracy And Inhibitory Control During Balance Recovery, Aric Turner, Sara Harper, Anne Beethe, David A. E. Bolton
International Journal of Exercise Science: Conference Proceedings
The ability to stop action is rarely considered when avoiding a fall, but mounting evidence indicates performance on traditional cognitive tests of response inhibition is related to fall prevalence. This suggests the ability to suppress action is important in how we control balance, and therefore, identifying practical ways to detect this important fall risk factor has potential clinical value. PURPOSE: Our aim was to assess inhibitory control using a simple hand reaction task (ReacStick®) in relation to performance on a reactive balance test where step suppression was occasionally required. METHODS: Eighteen adults (18-30 years) were first assessed on a …
