Effects of obesity and mild hypohydration on local sweating and cutaneous vascular responses during passive heat stress in females.

The purpose of this study was to evaluate the effect of obesity and mild hypohydration on local sweating (LSR) and cutaneous vascular conductance (CVC) responses during passive heat stress in females. Thirteen obese (age, 24 ± 4 years; 45.4% ± 5.

No Change in 24-Hour Hydration Status Following a Moderate Increase in Fluid Consumption.

Purpose: To investigate changes in 24-hour hydration status when increasing fluid intake.

Methods: Thirty-five healthy males (age 23.8 ± 4.

Forearm cutaneous vascular and sudomotor responses to whole body passive heat stress in young smokers.

The purpose of this study was to compare smokers and nonsmokers' sudomotor and cutaneous vascular responses to whole body passive heat stress. Nine regularly smoking (SMK: 29 ± 9 yr; 10 ± 6 cigarettes/day) and 13 nonsmoking (N-SMK: 27 ± 8 yr) males were passively heated until core temperature (TC) increased 1.5°C from baseline.

Hydration Status over 24-H Is Not Affected by Ingested Beverage Composition.

Objective: To investigate the 24-h hydration status of healthy, free-living, adult males when given various combinations of different beverage types.

Methods: Thirty-four healthy adult males participated in a randomized, repeated-measures design in which they consumed: water only (treatment A), water+cola (treatment B), water+diet cola (treatment C), or water+cola+diet cola+orange juice (treatment D) over a sedentary 24-h period across four weeks of testing. Volumes of fluid were split evenly between beverages within each treatment, and when accounting for food moisture content and metabolic water production, total fluid intake from all sources was equal to 35 ± 1 ml/kg body mass.

Effects of obesity on body temperature in otherwise-healthy females when controlling hydration and heat production during exercise in the heat.

Background: Previous studies investigating body temperature responses in obese individuals during exercise in the heat fail to control metabolic heat production or hydration status during exercise.

Purpose: To determine if there are differences in body temperature responses between obese and non-obese females when controlling metabolic heat production during exercise.

Methods: Twenty healthy females, ten obese (43.
