摔跤运动员减体重期的无机离子代谢

对12名男性摔跤运动员的水和无机离子代谢研究表明,受试者在减体重期钾、钠、钙和镁的摄入量显著低于正常水平,尿量减少,尿中四种离子排出量明显降低,血清中钾和镁浓度低于减体重前水平,但钠和钙浓度未出现明显变化。结果表明,采用综合措施长时间减体重的运动员应注意补充电解质。

METABOLISM OF ELECTROLYTES IN WRESTLERS DURING WEIGHT LOSS

The study of electrolyte metabolism was done in 12 voluntary male wrestlers who underwent weight-lossprogram for about one month and reduced 4.8% of their original weight. The results indicated that intakeof K, Na, Ca and Mg from diet decreased greatly when compared with that before weight loss. Averageurine volume and electrolyte elimination within 24 hours were significantly lower than normal level. Althoughno changes were observed in the concentrations of Na~+ and Ca~(2+) in serum, the levels of serum K~+ and Mg~(2+)declined. The results suggest the deficiency of electrolytes and necessity of electrolyte supplements duringweight loss of wrestlers.
