Competitive Status Of Elite Female Swimmers In China And The Variation Of Some Biochemical Indicators

Swimming is a kind of competitive sport that requires excellent quality in technology , tactics , physical ability and other aspects of athletes , so it should be studied in different subjects . this paper uses biochemistry method to test 110 china swim team female athletes continually for four years . the studied indexes include blood , urine and immunity index ,among which Hemoglobin , Blood Urea , Testosterone and Serum Testosterone/Cortisone are selected as important index . the result form statistical analysis indicated that the average value of Hemoglobin is 136.7±9.20 g/l , blood urea is 5.65±1.32mmol/L , Testosterone is 59.04±29.46ng/dl, Serum Testosterone/Cortisone is 3.38±2.40 , and the correlation coefficient among Hemoglobin and blood urea is small . in addition , luo××,yang×,zhu××,pang××,xu××and gao×who are famous in swimming sport are selected as excellent female athlete group , several other female athlete who are training together with them ,and performance is common ,are selected as common group . then comparing Hemoglobin , blood urea , Testosterone and Serum Testosterone/Cortisone between the two groups , the result is that Hemoglobin and Testosterone of excellent female athlete group are higher than common group . however , Blood Urea is a bit slower than common group , Serum Testosterone/Cortisone between two groups have no significant difference . we also analyzed changes of some biochemistry index in three training cycle for luo××,yang×,zhu××,pang××,xu××and gao×in preparing for the 10th world swimming championship in 2003 , the 26th Athens Olympic Games in 2004 and the 11th world swimming championship in 2005 , draw a diagram of different indexes , and compare their training achievement , at last , we get the conclusion that Hemoglobin,Testosterone are increasing , and Blood Urea is dropping ,which means that athletes are in good condition and can compete very well .
