在剧烈运动或从事耐力运动时,体内产热增加,出汗是主要的散热方式,汗液中98％～99％是水,其余主要为钾、钙、镁等无机盐。大量出汗后,需要及时补充水分,否则不仅导致疲劳和运动员体温调节障碍,也会引起酸性代谢产物的蓄积,从而导致疲劳和运动能力的下降。感到疲乏无力的运动员可能缺乏无机盐,且以肌肉细胞中缺乏钾和镁为特征。 研究表明,镁能促进糖原分解,加速能量代谢,提高运动成绩。缺镁时,葡萄糖通过无氧酵解途径产生乳酸,引起肌肉酸痛和痉挛。镁有助
In strenuous exercise or endurance exercise, the increase in body heat, sweating is the main way of cooling, sweat 98% to 99% of water, the rest are mainly potassium, calcium, magnesium and other inorganic salts. A lot of sweating, the need to replenish the water, otherwise not only lead to fatigue and athletes regulate body temperature disorders, but also lead to the accumulation of acidic metabolites, resulting in decreased fatigue and exercise capacity. Feel tired athletes may lack salt, and the lack of potassium and magnesium muscle cells characterized. Studies have shown that magnesium can promote the decomposition of glycogen, accelerate energy metabolism and improve exercise performance. Lack of magnesium, glucose through the anaerobic glycolysis to produce lactic acid, causing muscle aches and cramps. Magnesium helps
