TI  - Effects of medium-chain triaclyglycerol ingested with carbohydrate on metabolism 
      and exercise performance.
PG  - 35-47
AB  - The effects of ingesting different amounts of medium-chain triacylglycerol (MCT) 
      and carbohydrate (CHO) on gastric symptoms, fuel metabolism, and exercise 
      performance were measured in 9 endurance-trained cyclists. Participants, 2 hr 
      after a standardized lunch, cycled for 2 hr at 63% of peak oxygen consumption and 
      then performed a simulated 40-km time trial (Ttrial). During the rides, 
      participants ingested either 10% 14C-glucose (GLU), 10% 14C-GLU + 1.72% MCT 
      (LO-MCT), or 10% 14C-GLU +3.44% MCT (HI-MCT) solutions: 400 ml at the start of 
      exercise and then 100 ml every 10 min. MCT ingestion did not affect 
      gastrointestinal symptoms. It only raised serum free fatty acid (FFA) and 
      beta-hydroxybutyrate concentrations. Higher FFA and beta-hydroxybutyrate 
      concentrations with MCT ingestion did not affect fuel oxidation or T-trial 
      performance. The high CHO content of the pretrial lunch increased starting plasma 
      insulin levels, which may have promoted CHO oxidation despite elevated 
      circulating FFA concentrations with MCT ingestion.
