Antecedent diet can greatly influence both substrate utilization during exercise and exercise performance itself. A number of studies have convincingly demonstrated that short-term (three to seven days) adaptation to a low @entity1735 diet results in greatly reduced liver and muscle glycogen stores. While @entity1735 utilization after such a diet is reduced, the limited glycogen stores can severely limit endurance exercise performance. High @entity1735 diets on the other hand expand @entity1735 stores which can limit performance. However, long-term adaptation to a low @entity1735 diet can greatly alter muscle and whole body energy metabolism to drastically limit the oxidation of limited @entity1735 stores with no adverse effect on performance. Glycogen loading techniques can result in supercompensation of muscle stores. Exercise induced depletion of muscle glycogen is the most important single factor in this phenomenon. Following the exercise a low @entity1735 diet for two to three days after which a high @entity1735 diet is eaten seemingly has the same effect on increasing muscle glycogen stores as simply eating a high @entity1735 diet. The form of the dietary @entity1735 during glycogen loading should be high in complex @entity3363 ; however, the type of dietary starch that effects the greatest rate of resynthesis has not been investigated. Rapid resynthesis of glycogen following exercise is at least in part due to @entity1720 . The enhanced @entity413 transport caused by the increased sensitivity provides substrate for glycogen synthase. How rapidly this enhanced sensitivity returns to pre-exercise levels in @entity1 is uncertain.(ABSTRACT TRUNCATED AT 250 WORDS)
