Objective: In the process of load exercise training, with the discharge of sweat, the loss of water and electrolyte will destroy the balance of water and salt metabolism, and the athletic ability of athletes will also decline in varying degrees. Therefore, this paper studies the effect of exercise fluid supplementation on human metabolism after load exercise. The average value of the ionic concentration of athletes' sweat was used as the basis for the preparation of electrolyte sports drinks. Result: The results showed that the concentration of potassium ion in the sweat of male long-distance runners was significantly higher than that of female athletes; the concentration of potassium ion in male athletes of Sanda Team was significantly higher than that of female athletes; the test results of sodium, chlorine and potassium ion of long-distance runners were higher than that of Sanda athletes; Compared with the first week, the concentration of sodium, chloride and calcium ions in female athletes' serum increased in the fourth week, while the potassium ion concentration decreased slightly. Conclusion: After three weeks of load exercise, with the supplement of sports drinks containing appropriate electrolyte concentration, the concentration of serum chloride ion of athletes remained stable, slightly lower than that of the first week, but both were within the normal range; daily supplement of liquid supplement containing potassium ion and calcium ion had a slight decrease in serum potassium ion, and the decrease range was smaller than the former, and the calcium ion concentration was maintained compared with the first week During the period of load training, 800 ml of fluid was provided to athletes every day. After 3 weeks of rehydration, hematocrit remained stable, and there was no significant difference.
