体液调节激素在运动中的变化及其作用

Changes in Fluid and Electrolyte Hormones Induced by Exercise

目的:研究运动对体液调节激素产生的影响,以及激素的变化在运动中作用。方法:10名身体健康的男子(22±2岁)参加持续时间为1h强度为60%最大摄氧量的运动。分别在运动前,运动中及休息期间测定血浆心钠素(Atrial Natriuretic Peptides,ANP)、精氨酸加压素(Arginine Vasopressin,AVP)、醛固酮(Aldosterone,ALD)和血浆容量的变化(PV)。结果:血浆ALD、AVP和ANP在运动中明显升高,提示运动对体液调节激素的影响非常明显。运动中血浆容量明显下降,且与ALD、AVP具有高度相关性,提示运动中激素对维持血浆容量平衡起到非常重要的作用。结论: 运动对体液调节激素产生重要的影响,表现为运动中ALD、AVP和ANP明显增高;ALD、AVP是非常重要的体液调节激素,在运动中对维持体液平衡起到重要的作用。

Purpose: To study the effect of exercise on fluid and electrolyte hormones and the role ofaltered hormones in regulating the body fluid. Methods: Ten healthy and untrained men with ages of (22±2yrs) took part in an 1-h cycling exercise with the work load 60%VO2max. Before, during and after theexercise, the plasma ANP, ALD, and AVP were determined. Result: Plasma ANP, ALD, and AVP wereelevated pronouncedly. Plasma volume decreased 6.1%. The relationship between △ALD,△AVP and △PV was significant. Conclusion: 1.The effect of exercise on fluid and electrolyte hormones is significant. 2.Plasma ALD and AVP are key hormones in regulating fluid and electrolyte during exercise.
