VOLUNTARY DEHYDRATION AND HEAT INTOLERANCE IN CYSTIC FIBROSIS
Although exercise may be beneficial in cystic fibrosis (CF), patients' low tolerance to climatic heat stress means that physical exertion can increase morbid
HYDRATION IN CHILDREN.
Water supply is a basic public problem. In modern science, three periods with different approaches to define recommended water intake in adults can be distinguished. Pediatricians agree that hydration in children may be optimal only in breastfed infants. More data are required on the health effects of different hydration states and varying water intakes in [...]
Voluntary drinking and hydration in trained, heat-acclimatized girls exercising in a hot and humid climate.
This study examined the effects of beverage composition on the voluntary drinking pattern, body fluid balance and body temperature responses of heat-acclimatized trained girls exercising intermittently in outdoor conditions (WBGT = 30.9 +/- 0.2 degrees C). Twelve trained, heat-acclimatized girls (age = 10.6 +/- 0.2 years) performed three 3-h sessions, each consisting of four 20-min [...]
Oral hydration therapy for children in Florida.
Eighty-six children in Florida died of complications associated with diarrhea between 1985 and 1990, deaths which constituted an important preventable fraction of infant mortality. The state will support health professionals in reducing the number of hospitalizations and deaths due to diarrheal complications, Governor Lawton Chiles announced in September 1991, and the Florida Department of Health [...]
Drink composition, voluntary drinking, and fluid balance in exercising, trained, heat-acclimatized boys.
This study examined the effects of beverage composition on the voluntary drinking pattern, body fluid balance, and thermoregulation of heat-acclimatized trained boys exercising intermittently in outdoor conditions (wet bulb globe temperature 30.4 +/- 1.0 degreesC). Twelve boys (age 13.4 +/- 0.4 yr) performed two 3-h sessions, each consisting of four 20-min cycling bouts at 60% [...]
Consistency in preventing voluntary dehydration in boys who drink a flavored carbohydrate-NaCl beverage during exercise in the heat.
Twelve 10- to 12-year-old healthy boys performed six 70-min intermittent exercise sessions (three 20-min cycling bouts at 50% VO2max with 5 min rest in between) over a 2-week period at 35 +/- 1 degrees C, 50 +/- 5% or 60 +/- 5% relative humidity. Subjects drank grape-flavored solution with 6% carbohydrate (2% glucose, 4% sucrose) [...]
Hydration and cognitive function in children.
Massachusetts 02111, USA. Adequate fluid intake is critical for survival. While adults are at liberty to drink fluids as wanted, children and infants are dependent upon caregivers for food and fluid. Children are at greater risk for dehydration than adults due to their higher surface-to-mass ratio. Additionally, children have different thirst sensitivities and body cooling [...]
Effect of hydration and continuous urinary drainage on urine production in children.
OBJECTIVE: Although urine production depends on numerous physiological variables there are no quantitative data regarding the effect of bladder decompression, by means of continuous catheter drainage, on urine production. The aim of this study was to investigate this effect. MATERIAL AND METHODS: The study was carried out in two stages, each consisting of two phases. [...]
Heat illness in children.
With an increasing number of children and adolescents involved in competitive athletics throughout the calendar year, the sports medicine team must be familiar with preventing and treating heat-related illness. Heat illness is a spectrum of illnesses from heat cramps to heat stroke. Mortality for heat stroke ranges from 17% to 70%, depending on severity and [...]
