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. …

Effects Of Hot And Temperate Environments On Executive Function Tasks During Moderate And High Intensity Exercise, Stephen Decker, Heidi Bachrich, Nikki Kellman, La Tori Flowers, Eric J. Jones, Mark Faries

International Journal of Exercise Science: Conference Proceedings

Cognitive function testing during changes in body core temperature has been widely studied in regards to human performance, often employing passive hyperthermia. More recently, executive function (EF) testing during exercise has been addressed to assess changes in performance with some level of active hyperthermia. The purpose of the present study was to employ both external thermal stress and active hyperthermia in order to assess changes in executive function (EF) tasks within varying environmental temperatures before, during, and after a maximal treadmill test. Nine apparently healthy college-aged males participated in two trials of a Bruce protocol treadmill test in hot (35°C) …

The Impact Of Match-Play Tennis On Indirect Markers Of Oxidative Stress And Antioxidant Status, Wade L. Knez, Mohammed Farooq, Julien Périard

International Journal of Exercise Science: Conference Proceedings

Introduction: Research has shown that both heat stress and endurance exercise can result in an increase in oxidative stress; however, there is limited information regarding the impact of the combination on oxidative balance, in particular an exercise bout characterised by high-intensity long-duration intermittent activity such as tennis. The purpose of this study was to determine the impact of changes in oxidative stress and antioxidant status in response to two simulated tennis matches undertaken in cool (≈22° and 70%RH) and hot (≈36° and 35%RH) environments. Methods: Twelve high level (ITF rank 2-3) male tennis players volunteered to participate in the matches …
