dc.description.abstract Ten trained subjects were studied during and following exercise to determine the effects of fructose ingestion on muscle glycogen depletion and resynthesis. Three subjects cycled for anhour while the other six subjects completed a 3000-yard swim. The subjects ingested 12 grams of fructose before, 46 grams during, and 12 grams in the 30 minutes following the exercise. Muscle biopsies were obtained before, immediately after, and 12 hours post exercise. In -the cyclists, plasma glucose and insulin were also determined. The ingestion of fructose had no effect on the glycogen depletion during exercise. However, in the 12 hours following exercise, fructose ingestion resulted in a 41.4 mmole/kg-wet tissue increase in muscle glycogen. At the same time, the control period resulted in only a 9.53 mmole/kg-wet tissue increase in muscle glycogen. Plasma glucose and insulin levels increased during the fructose feeding. These data suggest that fructose ingestion during exercise has no effect in sparing muscle glycogen during work, but could significantly enhance the resynthesis of glycogen after work.
