THERMOREGULATORY RESPONSES OF PRE-, MID-, AND LATE-PUBERTAL BOYS TO EXERCISE IN DRY HEAT.

During exercise in a hot climate, children have been reported to have a less effective temperature regulation capability, compared with adults. It is likely that the transition from a child-like to an adult-like response occurs during puberty. To assess the association between the thermoregulatory response and physical maturation, three groups of circum-pubertal boys cycled at [...]

URINARY VOLUME, WATER AND RECURRENCES IN IDIOPATHIC CALCIUM NEPHROLITHIASIS: A 5-YEAR RANDOMIZED PROSPECTIVE STUDY.

PURPOSE: We define the role of urine volume as a stone risk factor in idiopathic calcium stone disease and test the actual preventive effectiveness of a high water intake. MATERIALS AND METHODS: We studied 101 controls and 199 patients from the first idiopathic calcium stone episode. After a baseline study period the stone formers were [...]

EFFECT OF BLOOD VOLUME ON SWEATING RATE AND BODY FLUIDS IN EXERCISING HUMANS.

Five relatively fit men performed cycle ergometer exercise (65-70% VO2max) for up to 30 min at 30 degrees C, 40% rh. The data from control (normo-volemic), hypovolemic [8.7% reduction in blood volume (BV) induced by diuretics], and hypervolemic [7.9% expansion of BV induced by infusion if isotonic serum albumin] tests revealed significant effects of BV [...]
