Effect of Carbohydrate Feeding During Recovery from Prolonged Running on Muscle Glycogen Metabolism During Subsequent Exercise

A higher muscle glycogen resynthesis was observed with 175 g of carbohydrate intake compared to 50 g during a 4-hour recovery.

• Muscle glycogen resynthesis was significantly greater in the 175 g carbohydrate group (75 +/- 20 mmol x kg dry matter -1) than in the 50 g group (31 +/- 11 mmol x kg dry matter -1).
• The rate of muscle glycogen utilization during subsequent exercise was similar for both carbohydrate intake levels (39 +/- 10 vs. 46 +/- 11 mmol x kg dry matter -1).
• Carbohydrate intake during recovery did not impact muscle glycogen utilization in later exercise.
