摘　　要： 脱水的出现不仅降低体温调节能力和运动能力 ,而且影响正常的心血管功能 ,通常这种影响随着脱水程度的变化而变化。当机体在运动中逐步脱水时 ,环境温度是影响心血管功能变化的一个重要因素。但是 ,当机体处于一个体液平衡的状态下 ,这种影响的显著性就消失了。运动时补液可以防止和纠正脱水 ,维持和改善运动时的心血管功能。补液的影响直接与补液量。 Dehydration affects not only temperature regulation,performance,but also normal cardiovascular functions.Usually,the negative effects induced by dehydration vary with dehydration levels.When a human body is gradually dehydrated during exercise,the environmental temperature is an important factor influencing cardiovascular functions.However,when a human body is well hydrated,this effect becomes not significant.Fluid replacement during exercise can prevent and correct dehydration,maintain and improve cardiovascular functions.It has been also suggested that the effect of fluid replacement on cardiovascular functions is directly related to ingested volume,ingesting time and the composition of ingested beverage.
