摘　　要：报道了青少年运动员在热环境下进行间歇性运动、补充不同含钠量（０ｍｍｏｌ／Ｌ、１８ｍｍｏｌ／Ｌ、３９ｊｍｍｏｌ／Ｌ、５９ｍｍｏｌ／Ｌ）饮料的多项生理指标反应。结果表明：补充含钠量为１８－５９ｍｍｏＬ／Ｌ的饮料优于无钠饮料。补充无钠饮料时，随运动时间延长，血浆渗透压和血浆钠浓度显著下降；补充含钠量为１８ｍｍｏｌ／Ｌ或３９ｍｍｏｌ／Ｌ饮料时，运动后收缩血压升高幅度小、恢复快，血浆钠水平和血浆渗透压相对稳定。从血压、体温增加值、体热蓄积、出汗量、血浆渗透压、血浆钠水平、血容量以及饮料的口感等指标综合评定，含钠量为１８ｍｍｏｌ／Ｌ和３９ｍｍｏｌ／Ｌ的饮料被认为最佳。This paper has reported the multiple physiological responses of young adolescent athletes taking an intermittent exercise under a hot environment supplemented with different sodium content drinks(Na content;0mmol/L ,18mmo/L;39mmol/L,and 59mmol/L),Results showed that Na content of 18-59 mmol/L drinks are better replacements than the drink with no Na inclusion.As exercise time was prolonged,plasma osmolaity and plasma Na levels decreased significantly as athletes were replace with Na free drink, Systolic pressure increased significantly lower and recovered more raplidy after the first bout of exercise,and plasma Na levels and plasma osmolality kept relatively stable as supplemented with the sodium content of 18mmol/L or 39 mmol/L drinks,From the aspect of multiple physiological responses including blood pressure,increase of average body temperature,body heat storage,sweat amount, plasma osmolality,plasma sodium,plasma volume and the taste of drinks,Na content of 18 mmol/L and 39mmol/L drinks were considered the best.
