Acute Heat Stress On Blood Composition & Body Fluid In Young And Middle-Aged Individuals, Kaitlyn Strong, Olivia Leach, Jayson Gifford Nov 2023

Acute Heat Stress On Blood Composition & Body Fluid In Young And Middle-Aged Individuals, Kaitlyn Strong, Olivia Leach, Jayson Gifford

International Journal of Exercise Science: Conference Proceedings

Sauna therapy has been shown to have benefits to cardiovascular health. Changes in hematocrit, hemoglobin, and plasma volume in response to sauna heating are not well defined in the middle-aged population. This population is of significant interest because of an increased rate of decline in cardiovascular health starting at middle age. PURPOSE: The purpose of this study was to examine the effect of acute sauna exposure on blood composition, specifically the change in plasma volume in young and middle-aged adults. METHODS: 10 young (24.9 ± 4.2 years, 6 male and 4 female) and 8 middle-aged adults (55.6 ± 3.9 …

Thirst Sensation Does Not Effect Reaction Time But Decreses Mood In Men, Alan Ky, Hui-Ying Luk, Jarrod Blinch, Yasuki Sekiguchi

International Journal of Exercise Science: Conference Proceedings

Exercise in hot environments results in dehydration accompanied by thirst sensation, a vital signal for fluid homeostasis. While cognitive performance and mood have been studied with exercise in hot environments and in dehydration states, no studies have investigated the effect of inducing thirst on cognitive performance and mood. PURPOSE: To investigate the effect of inducing thirst on cognitive performance and mood. METHODS: Twelve recreationally active men (mean±SE age: 29±3.6 years; body mass: 74.7±2.3 kg; height, 179.4±2.0 cm; maximal oxygen consumption [VO2max]: 49.8±1.9 ml·kg−1·min−1) performed 90 mins of cycling at 55% VO2max …

The Effect Of Heat Acclimatization And Heat Acclimation On Endurance Trained Athlete Substrate Utilization, Jacob T. Richardson, Yasuki Sekiguchi, Courteney L. Benjamin, Alan T. Ky, Douglas Casa

International Journal of Exercise Science: Conference Proceedings

Heat acclimatization (HAz) and Heat Acclimation (HA) are important strategies to induce thermoregulatory adaptations to mitigate negative impact of heat stress. However, despite improving endurance performance, few studies explore their impact on substrate utilization. PURPOSE: To investigate the effect of HAz and HA on endurance athlete substrate utilization during submaximal exercise in the heat. METHODS: Fourteen endurance-trained male athletes (mean ± SD; age, 33 ± 9 years; body mass, 70.9 ± 10.1 kg; height, 177.7 ± 6.4 cm; VO2max, 59.3 ± 7.4 ml·kg−1·min−1; % body fat, 8.5% ± 3.9%) participated in this …
