A Study On The Physical Function Of The 13th National Games In Shaanxi Province Taekwondo Team

Research purposes:the best factors of athletics tae kwon do project is "faster,higher,and control,accurate",requires athletes on the physical have fast starting speed and movement speed,strong stability and supportive forces,has a strong power,maximum strength and endurance and fast high sensitive flexible coordination[1].This research through to the shaanxi province taekwondo team prepare for the 13th national games grand cycle athletes body composition,RBC,hemoglobin,red blood cells,white blood cells,blood urea and hematocrit value of serum creatine kinase,urine protein,urine bile,etc,which are the indices of blood in the urine,and serum testosterone and cortisol index monitoring,analysis of the change of the indicators,provide scientific monitoring results and body function condition evaluation report,compete to provide theoretical reference for coaches scientific training.Research methods:this study took 7 members of the shaanxi taekwondo team who were preparing for the 13th national games as subjects.In the research process,the methods of literature,expert interview,observation,experiment and mathematical statistics were adopted.Research results:1.Prepare for the cycle,for weight problems need to strictly control the weight of two athletes,Yang**weight decreased from 63.4 kg to 60.7 kg,body fat percentage decreased from 6.8%to 3.8%,Yang**body composition has been effectively controlled,relatively stable functional status at the same time;It is difficult for zhang*to lose weight,and his physical function is affected after continuous weight loss.The overall weight and body fat percentage of male and female athletes during the whole preparation period showed a decreasing trend,among which the percentage of body fat of male athletes decreased more significantly than that of female athletes.2.Male athlete average red blood cell range(4.12 5.20)x 1012/L,hemoglobin range in g/L(148.00 163.00),red blood cell volume changes in the(43.00%49.95%),white blood cell range(5.18 6.50)× 109/L blood urea changes in the tendency for L(3.118.23),creatine kinase changes in(209.00 943.00)u/L,serum testosterone range(5.007.54)in ng/mL,The change range of cortisol was(218.25-329.25)ng/mL.Average red blood cell range in female athletes(3.61 4.30)x 1012/L,hemoglobin range in g/L(119.50 143.00),red blood cell volume changes in the(36.10%41.65%),white blood cell range(4.03 5.83)x 109/L,changes in blood urea in the tendency for L(3.43 5.80),creatine kinase changes in(91.70 377.00)u/L,serum testosterone range(0.30 0.50)in ng/mL,Cortisol varies from(173.00-255.67)ng/mL.There was a significant difference between the 4th test of cortisol in male athletes and the 3rd test(P<0.05),and the 8th test of serum testosterone in female athletes was significantly different from the 7th test(P<0.05).3.Male and female athletes to the number of red blood cells,hemoglobin increases overall,prepare for the winter training phases rise is more apparent,RBC hematocrit,white blood cells in the preparation period performance stability,blood urea,serum creatine kinase in the preparation period following the training load changes,presents the multiple wave,ansai training later,men and women,blood urea,serum creatine kinase showed higher rising trend.4.During the preparation period,serum testosterone of male athletes decreased from 6.95ng/ml to 5.00ng/ml,while that of female athletes increased from 0.43ng/ml to 0.50ng/ml.The male athletes showed multiple floating serum testosterone,overall performance stable,can be at a higher value,female athletes,2 female athletes serum testosterone decline after rising first,at a higher value,1 players down after up slowly,at the lower end in the long run.After training stimulation during the preparation period,testosterone showed an overall increase after adjusting for rest,and cortisol decreased slowly.5.five players in the preliminary preparation period of urine protein,urine bravery former not abnormal,two players preliminary preparation period abnormal,urine protein,urine bravery former tower of**in the fourth test urine protein,urine bravery former positive,10 times test positive urine protein;Xue**tested positive for urinary protein for the 8th time.During the occlusion training of ansai,the four athletes who are mainly preparing for the competition have repeatedly experienced minor abnormalities in urinary protein and urinary gallstone,and fewer serious abnormalities,which can be restored to normal after timely adjustment.Conclusion:1.Prepare for the period of winter training phase,the focus on athletes’ body weight,body fat percentage have appeared different degree of decline,the game task intensive competition,the athlete body weight,body fat percentage to cycle is relatively low;The preparation period you need to control body weight,weight loss of the athlete’s body composition has obvious improvement,five of them have reached the requirements of their weight,body weight and body in good shape,1 players greatly after reducing weight,body state is affected.2.During the training period,the weight and body fat percentage of male athletes in taekwondo team decreased more significantly than that of female athletes,among which the body fat percentage decreased more significantly.3.Male and female athletes number of red blood cells,hemoglobin rise at the end of the preparation period of winter training,red blood cell volume is relatively stable,after the winter training competition period number of red blood cells,hemoglobin,red blood cell volume is relatively stable;Serum urea and serum creatinine kinases are sensitive and are proportional to training intensity and load.Serum testosterone and cortisol also vulnerable to training intensity,the influence of load and the rise and decline,especially in the winter training period,the stages and prepare for the early physical ability training more cases,more prone to multiple frequency fluctuations,4 indexes of urine protein,urine uric bravery former performance in the preparation period is relatively stable,compared with the index of blood reaction is relatively lagging and stable,not easy to abnormal after intensive training,in the last stage of intensive training more abnormal(ansai closed training finals),including mild abnormal more,less serious abnormal situation,adjustment and easy to recover after the break.
