抄録

A study was performed to investigate the effect of ingestion of two different carbohydrates immediately after exhaustive exercise on muscle glycogen restoration in rats. The carbohydrate solu-tions used were 20% maltodextrin (osmolality: 270 mOsm/kg⋅H2O) and 20% glucose (osmolality: 1370mOsm/kg·H2O) . At both 30 and 60 min after oral ingestion, the osmolality in the gastric residue was significantly higher in the group given the glucose solution than in the group given the maltodextrin solution. The concentration of serum glucose at both 30 and 60 min after oral ingestion was significantly higher in the group given maltodextrin than in the group given glucose. Compared to the group given glucose, the group given maltodextrin had significantly higher muscle glycogen contents in M. plantaris and M. gastrocnemius at both 30 and 60 min after oral ingestion. Furthermore, the muscle glycogen contents in the group given maltodextrin returned to the levels in resting control rats 60 min after oral ingestion. Thus it is concluded that ingestion of maltodextrin solution immediately after exhaustive exercise might be effective for rapid restoration of muscle glycogen.
