Purpose Cold-induced vasodilation (CIVD) is known to protect humans against local cold injuries and improve manual dexterity. The current study examined the effects of metabolic heat production on cold-induced vasodilation responses in normobaric hypoxia and normoxia. Methods Ten participants immersed their non-dominant hand into 5 °C water for 15...

Objective: To determine whether 2 days of staging at 2500-3500 m, combined with either high or low physical activity, reduces acute mountain sickness (AMS) during subsequent ascent to 4300 m. Methods: Three independent groups of unacclimatized men and women were staged for 2 days at either 2500 m (n = 18), 3000 m (n = 16), or 3500 m (n = 15) bef...

Low-cost physical activity monitors may provide a more accurate measure of physical activity than subjective methods (e.g., self-report) while being less costly than research-grade accelerometers. The present study assessed the validity of a low-cost monitor (Movband 2) to estimate physical activity behavior/intensity. Participants (N = 23, n = 16...

Background & aims: Caffeine intake in a convenience sample of U.S. college students (N = 1248) was surveyed at five geographically-dispersed United States (U.S.) universities. Methods: Intake from coffee, tea, soft drinks, energy drinks, gums, and medications was assessed. Associations between caffeine intake and demographic variables including...

Tumor Necrosis Factor‐alpha (TNF‐α) is a pro‐inflammatory cytokine that is known to increase during exercise in the heat, however, has not been examined in a cold environment. OBJECTIVE The purpose of this study was to examine the circulating concentration of TNF‐α and the corresponding expression of TNF‐receptor 1 and 2 (TNFr1 and TNFr2) on class...

Plasma levels of Tumor Necrosis Factor‐alpha (TNF‐α) have been shown to increase in response to exercise in hot environments, however, the effects of exercise in the heat on surface expression of TNF receptors (TNFR) 1 and 2 have not been investigated. OBJECTIVE To observe the effects of moderate‐ and high‐intensity exercise in the heat on circula...

Abstract Background To determine the effectiveness of a low-cost 12-week worksite physical activity intervention targeting a goal of 10,000 steps per day on reducing anthropometric indices, blood pressure indices, and plasma biomarkers of cardiovascular disease (CVD) risk among the employees of a major university. Methods Fifty university employees...

Purpose: Respirators are simple and efficient in protecting workers against toxic airborne substances; however, their use may limit the physical performance of workers. The purpose of this study was to determine the effect of inspiratory resistance on physical performance and breathing perception in normobaric hypoxia. Method: Nine healthy men w...

Background: Hypoxia and exercise each exhibit opposing effects on executive function, and the mechanisms for this are not entirely clear. This study examined the influence of cerebral oxygenation and perfusion on executive function during exercise and recovery in normobaric hypoxia (NH) and normoxia (N). Methods: There were 18 subjects who compl...
