马拉松运动在消耗巨大体能的同时,也伴随水分和电解质的大量丢失。如果不能科学合理地补水,极易导致急性脱水、电解质失衡和乳酸堆积等情况发生,严重时可诱发运动性中暑、运动性低钠血症、运动性酸中毒,甚至死亡。为了保持良好的水合状态及电解质平衡,需要做到:密切关注身体水合状态;运动前主动让身体充分水化,运动中既要防止脱水也要防止过度补水,运动后及时补充丢失的水分。同时还要注意结合环境条件及自身特征调整补水方案。选择含有适量电解质、矿物质和碳水化合物的运动饮料或饮水,避免单纯摄入纯水(纯净水、蒸馏水等)。
There exist great energy expenditure and a large quantity of fluid and electrolyte loss in marathon running. Inappropriate hydration strategies will result in acute dehydration
electrolyte imbalance
accumulation of lactic acid
and in some serious cases
exertional heat stroke
exercise-associated hyponatremia and exercise-induced metabolic acidosis
and even death. In order to keep fluid and electrolyte balance
the following hydration strategies should be adopted: paying close attention to hydration status
keeping balanced diet and euhydration before running
preventing excessive dehydration or overhydration during running
and supplementing fluid and electrolyte timely after running. What's more
personalized hydration strategies should be employed according to the environmental conditions and his/her own characteristics. It would be better to consume sports drinks or fluids with an appropriate amount of electrolytes
minerals and carbohydrate
and avoid drinking purified water only.
