TI  - Effects of ingesting a large volume of carbohydrate-electrolyte solution on 
      rehydration during recovery and subsequent exercise capacity.
PG  - 375-93
AB  - This randomized, double-blind study examined the effects of rehydration per se 
      and rehydration plus carbohydrate (CHO) ingestion during recovery (REC) on 
      subsequent endurance running capacity. Nine men ran at 70% VaO2max on a level 
      treadmill for 90 min (T1) on two occasions, followed by a 4 hour REC and a 
      further exhaustive run at the same speed (T2). During the first 3 hours of REC, 
      subjects drank either a 6.9% CHO-electrolyte solution (CE) or a CHO- and 
      electrolyte-free sweetened placebo (PL) every 30 min. Volumes prescribed were 
      200% of the fluid lost after T1, but the actual volume of fluid ingested during 
      the REC ranged from 113-200% and 88. 5-200% of the body mass lost for the CE and 
      PL trials (NS). However, positive fluid balance was found in both trials after 
      REC. During T2, run time was 24.3 +/- 4.4 min longer in the CE trial (69.3 +/- 
      5.5 vs. 45.0 +/- 4.2 min; p <.05). Higher blood glucose concentrations were 
      observed throughout REC in the CE trial. These results suggest that ingesting a 
      CHO-electrolyte solution is more effective in restoring endurance capacity 
      compared to the same large volume of placebo, even though complete rehydration 
      was achieved in both trials.
