COMPARISON OF GROUND-BASED AND SPACE FLIGHT ENERGY EXPENDITURE AND WATER TURNOVER IN MIDDLE-AGED HEALTHY MALE US ASTRONAUTS.

Energy requirements during space flight are poorly defined because they depend on metabolic-balance studies, food disappearance, and dietary records. Water turnover has been estimated by balance methods only. The purpose of this study was to determine energy requirements and water turnover for short-term space flights (8-14 d). Subjects were 13 male astronauts aged 36-51 y [...]

DIFFERENTIAL EFFECTS OF SAUNA-, DIURETIC-, AND EXERCISE-INDUCED HYPOHYDRATION.

The physiological effects on submaximal and maximal exercise of three methods commonly used by athletes for achieving rapid weight loss were determined by measuring cardiorespiratory variables in 62 nonendurance athletes. A mean weight loss of 4.1% was achieved by those who followed either a sauna (SAU), diuretic (DIU), or exercise (ACT) protocol, compared with the [...]

DEHYDRATION IN SOLDIERS DURING WALKING/RUNNING EXERCISE IN THE HEAT AND THE EFFECTS OF FLUID INGESTION DURING AND AFTER EXERCISE.

The aim of this study was to examine whether ingesting water alone, or dextrose (7.5 g x 100 ml(-1)) with electrolytes, or fructose/corn solids (7.5 g x 100 ml(-1)) (400 ml every 20 min) would reduce the perceived exertion associated with 16 km (3 h) walking/running in the heat compared with that perceived during exercise [...]

THERMAL AND CIRCULATORY RESPONSES DURING PROLONGED EXERCISE AT DIFFERENT LEVELS OF HYDRATION.

After a control experiment under initial normal hydration (N), five healthy unacclimated subjects were studied to investigate the effects of initial hypo- and hyperhydration on cardiovascular and thermo-regulatory responses to prolonged intermittent exercise in the heat (To = 36 degrees C; Tdp = 10 degrees C; Va = 0.6 m.s-1). Prior hydrohydration (O) was obtained [...]

HYPONATREMIA ASSOCIATED WITH OVERHYDRATION IN U.S. ARMY TRAINEES.

This report describes a series of hyponatremia hospitalizations associated with heat-related injuries and apparent over-hydration. Data from the U.S. Army Inpatient Data System were used to identify all hospitalizations for hyposmolality/hyponatremia from 1996 and 1997. Admissions were considered as probable cases of overhydration hyponatremia if this was the only, or primary, diagnosis or if it [...]

INFLUENCES OF HYDRATION ON POST-EXERCISE CARDIOVASCULAR CONTROL IN HUMANS.

Dehydration is known to decrease orthostatic tolerance and cause tachycardia, but little is known about the cardiovascular control mechanisms involved. To test the hypothesis that arterial baroreflex sensitivity increases during exercise-induced dehydration, we assessed arterial baroreflex responsiveness in 13 healthy subjects (protocol 1) at baseline (PRE-EX) and 1 h after (EX-DEH) 90 min of exercise [...]

INFLUENCE OF HYDRATION STATUS AND FLUID REPLACEMENT ON HEAT TOLERANCE WHILE WEARING NBC PROTECTIVE CLOTHING.

The purpose of the present study was to investigate the influence of hypohydration and fluid replacement on tolerance to an uncompensable heat stress. Eight healthy young males completed a matrix of six trials in an environmental chamber, set at 40 degrees C and 30% relative humidity, while wearing nuclear, biological, and chemical protective clothing. Subjects [...]
