AB  - This study was conducted to compare blood glucose and glucoregulatory hormone 
      responses to the ingestion of solid and liquid carbohydrate (CHO) during 
      prolonged cycling, followed by 30 min of isokinetic cycling. Eight male cyclists 
      randomly completed three cycling trials (LC = liquid CHO, SCE = solid CHO with 
      water equal to LC, SCA = solid CHO + ad libitum water). Each subject cycled for 
      120 min at 65% of VO2max with CHO ingestion (0.6 g CHO/ kg/hr) at 0, 30, 60, 90, 
      and 120 min. Subjects then completed a 30-min maximal isokinetic ride at 90 rpm. 
      There was no significant (p < .05) difference between the trials for plasma 
      glucose, insulin, glucagon, glycerol, lactate, RER, HR, VO2, RPE, and total work 
      performed during the isokinetic ride. However, serum glucose was significantly 
      lower in the SCE and SCA trials compared to LC at 80 min. The ingestion of a 
      solid food containing CHO, protein, and fat with added water produced similar 
      blood glucose, metabolic, glucoregulatory hormone, and exercise performance 
      responses to those seen with the ingestion of liquid CHO.
