The Analysis On Major Biochemical Indexes Of Jilin Province Excellent Short Track Speed Skaters During The National Championship

With the rapid development of Science and competitive sports, it is more and more seriously for the Scientific sports training. Male’s short track speed skating project is the advantage of competitive sports in Jilin province. Through the comprehensive analysis for a number of biochemical indexes can reflect the athletes in the various stages of functional status before the game, and can be reference for scientific training to provide accurate load data. It is one of the essential requirements of scientific monitoring and before the performance prediction. Statistical analysis of monitoring blood biochemical indexes and associated with the results of the competition will adjust training for coaches load and provide a scientific basis for improve the results of the competition.Based on investigation and study of short track speed skating project in different stages and biochemical index, during the prepare for the 2013-2014 national short track speed skating championships(audition for the Sochi Winter Olympic), elite male short track speed skating project seven athletes in Jilin province for two months had been monitored biochemical indexes before the Championship, Selection of biochemical indicators include: white blood cells, hemoglobin, creatine kinase, blood urea and blood testosterone. For training index change range of different stages and the results are analyzed, studying the change rule characteristics of biochemical indexes during the training period, and putting forward the signal variation characteristics of indexes, providing beneficial reference on the basis of individual skills project status to arrange exercise load for the men’s short track speed skating in Jilin province. It will provide scientific basis Training for the later to prepare annual events in our province, and has the great significance for improving the level of scientific training in the short track speed skating project.The results include the following:1 During prepare for the Short track speed skating Championship of china in 2013-2014, all of biochemical indexes had significant changes in the third week before the Championship. The change of WBC(white blood cell) and CK(creatine kinase) has large individual differences. For the intensity of training load, CK is sensitive to white blood cells. Through the observation found that the values of Hb(hemoglobin) in different training period has all within the reference range, the most of them is more than 140g/L.For the training load, Urea(blood urea) is sensitive,but its restore is slower.2 If the value of WBC is less than 4.0×109/L, it heralds the poor immune function in the first week before the game; If the value of CK is more than 200 U/L, it means athletes don’t adapt to their training load intensity, and heralds the poor function recovery of skeletal muscle system&tissue; If the value of Hb is less than 130 g/L, blood urea is more than 7.0 mmol/L and blood testosterone is around 350 ng/dl, it heralds the poor athletes’ functional status, they do not adapt to training load.3 It is a precondition for excellent achievements of the championship that the relatively stable of Hb, WBC and blood testosterone. During the preparation of the championship, the elite athletes’ value of CK and blood urea have larger fluctuation, but they can restore to the base value in the first week before the championship( WBC is more than 4.0×109/L, CK is less than 150 U/L, Hb is more than 150 g/L, blood urea is less than 6.5 mmol/L, blood testosterone is around 500ng/dl).If it is large difference form the base value, athletes’ results of game will not good.4 During important events for short track speed skating project, through the scientific method to adjust the training load and body function, Make the hemoglobin, white blood cells and blood testosterone index change is relatively stable; Creatine kinase and blood urea can appear during the period of preparation for a significant change.But should be in a week before the game near the base value, predict the results of the competition is excellent. As a significant change of biochemical index, should timely adjust, optimize individual biochemical indicators; If the regulation effect is bad, is poor performance.
