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。
Reported a number of physiological responses of young athletes to intermittent exercise in a hot environment supplemented with different sodium levels (0 mmol / L, 18 mmol / L, 39 mmol / L, 59 mmol / L). The results show that: Supplementary sodium content of 18-59mmoL / L beverage is superior to non-sodium drinks. When supplemented with sodium-free beverage, plasma osmolality and plasma sodium concentration decreased significantly with prolonged exercise time. When sodium supplementation was 18 mmol / L or 39 mmol / L, the increase in systolic blood pressure was small and recovered quickly after exercise. Plasma sodium Level and plasma osmolality are relatively stable. From the blood pressure, body temperature increase, body heat accumulation, sweating volume, plasma osmolality, plasma sodium level, blood volume and beverage taste and other indicators of comprehensive evaluation of the sodium content of 18mmol / L and 39mmol / L of the beverage is considered the most good.
