TI  - Effect of frequency of carbohydrate feedings on recovery and subsequent endurance 
      run.
PG  - 315-23
AB  - PURPOSE: This study examined the effect of feeding pattern of a high glycemic 
      index (GI) meal during a short-term recovery on subsequent endurance capacity. 
      METHODS: Eight men ran at 70% .VO2max on a level treadmill for 90 min (T1) on two 
      occasions, followed by 4-h recovery (R) and a further exhaustive run at the same 
      speed (T2). During the R, subjects consumed a prescribed meal with a GI of 77 in 
      either a "gorging" (GOR) or "nibbling" (NIB) intake pattern, providing 1.5 g 
      carbohydrate (CHO) per kilogram body mass. In the GOR trial, the foods were 
      consumed in a single bolus, 20 min after the end of T1. In the NIB trial, the 
      same quantity of food was ingested in three equal portions; the first consumed 20 
      min after the end of T1 and the remainder at hourly intervals thereafter. 
      RESULTS: The run time during T2 was similar between trials (GOR vs NIB: 68.1 +/- 
      8.2 vs 66.8 +/- 8.7 min, P > 0.05). However, CHO utilization was lower and fat 
      utilization higher during T2 in the GOR trial compared with the NIB trial (GOR vs 
      NIB: CHO: 94.4 +/- 11.4 vs 117.6 +/- 10.6 g, P < 0.05; FAT: 55.9 +/- 8.0 vs 44 
      +/- 8.6 g, P < 0.01). CONCLUSIONS: These results suggest that serial consumption 
      of a high GI meal during a 4-h recovery increased the reliance on CHO oxidation 
      for energy provision during a subsequent run when compared with a single feeding. 
      However, there was no difference in the duration of the exhaustive run after the 
      recovery between the GOR and NIB trials.
