Description
This study examined influence of carbohydrate ingestion patten on performance and metabolism in prolonged bicycle exercise. Six male subjects cycled at lactate threshold level for 90min. Immediately after the prolonged exercise,the subjects were given performance test in which time to exhaustion was measured during bicycle exercise demanding oxygen consumption the double of lactate threshold level. During the prolonged exercise the subjects ingested either 10% carbohydrate (CHO) drink, 5%CHO drink,or water every 15min on five pattens; 1) 10%CHO drink at the first half followed by water at the second half,2) 5%CHO drink at the first half and water at the second half,3) 5%CHO drink throughout exercise period,4) water at the first half followed by 10% CHO drink at the second half,5) water at the first half and 5%CHO drink at the second half. When CHO drink was ingested at the first half,plasma glucose was significantly higher at 60min from the beginning of exercise than that of the patten where CHO was ingested on the second half.There was not a significant difference in blood glucose level at the end of the prolonged exercise,with the values being around 5mM irrespective of the ingestion pattens. The different ingestion patterns induced no significant differences in performance time,the amount of CHO oxidized,and such gas parameters as oxygen consumption,minutes ventilation,respiratory exchange ratio.
