Intravenous versus oral rehydration during a brief period: responses to subsequent exercise in the heat

Article Abstract:

Results show that under hot conditions partial oral rehydration produced less physiological strain as opposed to partial intravenous rehydration during exercise. The study also suggests that despite any significant differences between the two modes of rehydration, oral route is better due to its consistently better physiological response behavior.

Perceptual responses in the heat after brief intravenous versus oral rehydration

Article Abstract:

This article compares the effects of oral and intravenous fluid rehydration on perceptions of thirst, exertion, and thermal sensation among a sample of trained cyclists during an exercise test in high temperatures. Findings indicate that oral rehydration facilitated reduced perceptions of thirst, exertion, and thermal sensation when compared to intravenous rehydration.

No effect of 5% hypohydration on running economy of competitive runners at 23 degrees Celsius

Article Abstract:

The effects of hypohydration (HY) on running economy (RE) and associated physiological responses are examined. Results show that HY does not alter the RE or lactate accumulation of endurance athletes during 10 minutes of exercise at 70 and 85 percent maximal oxygen uptake (V[O.sub.2max]), suggesting that HY has no effect on RE, but increases physiological strain in a 23 degrees Celsius environment.
