运动性尿蛋白是评定运动员身体机能状态的重要指标之一,当运动员机能状态下降时,尿蛋白排出量增多.但尿蛋白组成的变化如何,尚未见到报导.文献报告用凝胶和放射免疫电泳,以及层析方法分析运动性尿蛋白时与血桨蛋白质、正常尿蛋白的成份相似.滤纸上电泳,因方法所限,清蛋白多而球蛋白很少,或没有.醋酸纤维薄膜电泳时,分离的效果较好,中跑后尿中出现的蛋白组成与血浆相似,但有时无α_1球蛋白.本文采用醋酸纤维薄膜方法,对游泳运动员在不同性质训练和比赛后进行尿蛋白电泳,并与非运动员比较,以了解在不同运动负荷时,身体机能状态与尿蛋白电泳组成成份的关系,为机能评定提供参考.一、研究对象和方法研究对象北京体院竞技体校游泳队运动员33人,年龄11-18岁;非运动员对
Urine protein is one of the most important indexes to assess the functional status of athletes. When the functional status of athletes decreases, urinary protein excretion increases, but the changes of urinary protein composition have not been reported yet. Electrophoresis, and chromatographic analysis of urinary protein with the blood protein, normal urinary protein composition similar to the electrophoresis on the filter paper, due to the method limitations, albumin and more globulin few or no. Acetate film electrophoresis , The effect of separation was better, and the protein composition in urine appeared similar to plasma in middle run, but sometimes there was no α_1 globulin.In this paper, acetate film method was used to carry out urinary protein electrophoresis for swimmers after different training and competition Compared with non-athletes to understand the relationship between body function status and urinary protein electrophoresis composition under different exercise loads, and provide a reference for the performance evaluation.Materials and Methods Subjects: Beijing Institute of Physical Education athletics swimming team athletes 33 , Ages 11-18 years; non-athlete pair
