The purpose of the current study was to test the hypothesis that the beta-adrenergic innervation of the human eccrine sweat gland facilitates greater sweat production following heat acclimation. Eight healthy subjects (mean ± SD age: 25.1 ± 4.1 years, weight: 79.0 ± 16.1 kg, and VO(2)max: 48.5 ± 8.0 ml/kg/min) underwent active heat acclimation by walking at(More)
INTRODUCTION Warfighters often train and conduct operations in cold environments. Specifically, military trainees and divers that are repeatedly exposed to cold water may experience inadvertent cold acclimatization, which results in body heat retention. These same warfighters can quickly switch between environments (cold to hot or hot to cold) given the(More)
This paper introduces SQURL, a new programming language designed to fulfill a need for a simple, flexible alternative to languages currently available for micro-computers. SQURL is a structured language designed for general purpose applications and intended for implementation on almost any micro-computer. A compiler does exist.
Athletes, occupational workers, and military personnel experience cold temperatures through cold air exposure or cold water immersion, both of which impair cognitive performance. Prior work has shown that neurophysiological pathways may be sensitive to the effects of temperature acclimation and, therefore, cold acclimation may be a potential strategy to(More)
The purpose of this study was to determine the time course of the attenuation in sympathetic nervous activity during active heat acclimation (HA) in healthy humans. Eight volunteers completed a maximal graded exercise test followed by 8 days of active HA. Heat acclimation consisted of 90 min of walking at 40% of maximal oxygen uptake in a heated(More)
