We investigated the effect of glucose and glucose polymer ingestion on plasma arginine vasopressin (pAVP) levels, on plasma osmolality (p-osm), and on performance during two prolonged endurance events. The study subjects were 37 Finnish elite endurance athletes, of whom 18 were orienteers and 19 cross-country skiers. Plasma AVP increased in both combined glucose and glucose polymer groups, but the increase in the glucose polymer group was significantly smaller (P less than 0.001) than that in the glucose group. A significant change in p-osm caused a significant change in pAVP and vice versa. Both the orienteers and the skiers on glucose polymer tended to have more success in the competition; the orienteers on glucose polymer ran the last third of the competition significantly faster than those on glucose (P less than 0.05). It is suggested, in the light of the smaller pAVP response, that after glucose polymer ingestion the physical stress in prolonged endurance exercise is smaller than after ingestion of glucose.
我们研究了摄入葡萄糖和葡萄糖聚合物对血浆精氨酸加压素（pAVP）水平、血浆渗透压（p-osm）以及两项长时间耐力运动表现的影响。研究对象为37名芬兰优秀耐力运动员，其中18名为定向越野运动员，19名为越野滑雪运动员。葡萄糖组和葡萄糖聚合物组的血浆AVP均升高，但葡萄糖聚合物组的升高幅度显著小于葡萄糖组（P<0.001）。p-osm的显著变化会导致pAVP的显著变化，反之亦然。摄入葡萄糖聚合物的定向越野运动员和滑雪运动员在比赛中往往更成功；摄入葡萄糖聚合物的定向越野运动员在比赛的最后三分之一赛程中跑得比摄入葡萄糖的运动员明显更快（P<0.05）。鉴于pAVP反应较小，有人认为，摄入葡萄糖聚合物后，长时间耐力运动中的身体应激小于摄入葡萄糖后。
