运动饮料亦称电解质饮料,含有钾、钠、钙、铁、磷等多种矿物质。这些矿物质在人体中起稳定细胞内外渗透压,维持体液平衡和酸碱平衡、参与能量代谢,保证心肌和骨胳肌及神经细胞正常功能等重要生理作用。运动员运动时出汗增多,失去体内水分的同时也失去电解质,如补充不及时,就会引起机体内水、电解质平衡和酸碱平衡的紊乱,出现一系列生理代谢功能失调症状,从而降低运动能力,因此,运动饮料具有补充能量,调节人体内酸碱平衡和水、电解质平衡,消除运动性疲劳,提高运动能力之功效。
Sports drinks, also known as electrolyte drinks, containing potassium, sodium, calcium, iron, phosphorus and other minerals. These minerals play an important physiological role in the body, such as stable intracellular and extracellular osmotic pressure, maintaining body fluid balance and acid-base balance, participating in energy metabolism, and ensuring the normal function of myocardium and skeletal muscle and nerve cells. Athletes sweat increased movement, loss of body water while also losing electrolyte, such as supplement is not timely, it will cause the body’s water, electrolyte balance and acid-base balance disorders, a series of physiological metabolic dysfunction symptoms, thereby reducing exercise capacity Therefore, the sports drink has the functions of replenishing energy, regulating acid-base balance, water and electrolyte balance, eliminating exercise-induced fatigue and improving exercise capacity in the human body.
