TI  - Effect of carbohydrate feeding during recovery from prolonged running on muscle 
      glycogen metabolism during subsequent exercise.
PG  - 452-8
AB  - This study examined the effect of carbohydrate (CHO) intake during a 4 h recovery 
      from prolonged running on muscle glycogen metabolism during subsequent exercise. 
      On 2 occasions, 7 male subjects ran for 90 min at 70 % maximum oxygen uptake VO(2 
      max) on a motorized treadmill (R1) followed by a 4 h rest period (REC) and a 15 
      min run (R2) consisting of 5 min at 60 % and 10 min at 70 % VO(2 max) During REC, 
      each subject ingested a total of 2.7 l of an isotonic solution containing either 
      50 g of CHO (LOW) or 175 g of CHO (HIGH). Biopsy samples were obtained from the 
      vastus lateralis immediately after R1, REC and R2. During REC, a higher muscle 
      glycogen resynthesis was observed in HIGH when compared with LOW trial (75 +/- 20 
      vs. 31 +/- 11 mmol x kg dry matter (dm) -1, respectively; p < 0.01). Muscle 
      glycogen utilization during R2 was similar between the HIGH and LOW trials (39 
      +/- 10 vs. 46 +/- 11 mmol x kg dm -1, respectively). These results suggest that 
      ingestion of a large amount of CHO at frequent intervals during recovery from 
      exercise does not affect the rate of muscle glycogen utilization during 
      subsequent exercise.
