ROWING PERFORMANCE, FLUID BALANCE, AND METABOLIC FUNCTION FOLLOWING DEHYDRATION AND REHYDRATION.

Eight international class lightweight rowers were examined to determine the efficacy of rehydrating with water following 24 h of dehydration on body fluid balance, metabolic function, and rowing performance. The rowers performed a maximal rowing trial on a Gjessing rowing ergometer (4200 revs, 3-kg resistance) while euhydrated (ET) and following partial rehydration (RT). Body weight [...]

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 [...]

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 [...]

PHYSICAL FITNESS INFLUENCES WATER TURNOVER AND BODY WATER CHANGES DURING TREKKING.

PURPOSE: This study was performed to assess water turnover and changes of body water during a trekking tour at moderate altitude. METHODS: Fifteen healthy normally trained adults participated in a 7-d backpack trek tour in the Swiss Alps (total walking distance: 120.5 km; cumulated altitude difference: 6990 m (uphill) and 7550 m downhill; lowest point: [...]
