摘要
目的研究湿热环境及高强度体能训练对青年篮球运动员若干生化指标的影响,以探讨运动性疲劳有效营养措施。方法在湿热环境(干球温度28℃,湿球温度27.5℃,相对湿度>100%)下,运用心率遥测仪对10名篮球运动员安排相应高强度专项体能训练监控;分别在训练前及训练后即刻抽取静脉血,测定训练前、后Glu,BUN,CK,CK-MB,K+,Na+,Cl-及血清总钙(Ca)及全血总钙(Ca)含量。比较评价高强度篮球体能训练前、后对机体糖代谢、心肌细胞、电解质代谢以及体重的影响。结果训练后BUN,CK,CK-MB,Glu,Na+,Cl-含量均显著升高,而体重与K+含量下降。结论高强度训练对运动员体液及糖量的消耗较大,应及时补充;同时也要密切关注高强度训练对于心肌细胞功能的损伤和电解质的紊乱,尤其是K+的变化。
Aim To provide theory fOulldation for how to take the valid nourishment measures to avoid sports fatigue, to research the influences of humid heat environment and high intensity training upon glycometabolism, electolyte metabolism and other indicators of young male basketball athletes. Methods Under the humid heat environment （dry bulb temperature is 28℃, the wet bulb temperature is 27.5℃, relative humidity 〉 100% ）, physics fitness intensity of training is monitoried by HR telemeter（HR）, blood levels of GIu,BUN, CK, CK- MB and some electrolytes of 10 CUBA male athletes were assayed and compared before and after training high intensity specialpurpose physics fitness proceedings. Results After training, the levels of BUN, CK, CK - MB, Glu, Na^＋ , Cl^- are all in increase, but the body weight and potassium level are in decrease. Conclusion Under the humid heat environment, high strength physical training make athletes consume more body fluid and sugar, at the same time, the cardiac muscle cell function may be damaged and electrolyte may be disorderd.
