Text: Following dehydration (-4 % of body weight), eight nonacclimated highly trained cyclists (age = 23. 5 + / - 1. 2 yr ; VO2peak = 61. 4 + / - 0. 8 mL x kg x min (-1) ; body fat = 13. 5 + / - 0. 6 %) rehydrated and then cycled at 70 % VO2peak to exhaustion in 37 degrees C. Rehydration (randomized, cross-over design) included : 1) CONTROL (no fluid), 2) DRINK (oral rehydration, 0. 45 % NaCl) equal to 50 % of prior dehydration, and 3) IV (intravenous rehydration, 0. 45 % NaCl), equal to 50 % of prior dehydration.
