Study On The Change Of Some Biochemistry Index And Strength Of Women Judo Athletes And Nutrition Intervene During The Loss Of Weight

Aims of Research:Women judo is one of the most important items which can win the gold medal in the Olympic Games.Chinese athletes have achieved great achievements since Judo entered the Barcelona Olympics in 1992.If China Judo team wants to effect a real breakthrough,break the many-year deadlock of "keep one gold and aim to get two" and get more brilliant results at home in 2008,a great effort must be made.This thesis attempts to probe the means and way of improving the athletes' capacity of sports and fully utilizing their skills.Methods of Research:24 judo athletes from Inner Mongolia are randomly divided into groups of common loss of weight(n=8),loss of weight with common nutrition(n=8) and loss of weight with nutrition intervene(n=8) according to their weight.Experiment period is 2 weeks,the athletes of all groups,on average,take in 800-1200kcals.d^-1 heat(about 35%protein,10%fat and 55%carbohrate).The group of loss of weight with common nutrition are reinforced with multiplex vitamin,minerals and an amount of oligosaccharide,which are taken 2 weeks before the experiment;the group of loss of weight with nutrition intervene take in substances which can stimulate the compounding such as glutamine,triandrobol,HMB,which are taken 2 weeks before the experiment.High strength exercises are mainly arranged within the two-week training.To prevent any injure and illness, 8-12mmol/L blood lactate,Bla is the supervising index.The Result of Experiment:1.The change of anthropometry index:all of the weight,the percentage of body fat,the fat weight and body mass index have obviously fallen(p＜0.01),the change of lean body mass can hardly be seen(p＞0.05).2.The common biochemistry index change of body function estimation:The rate of testosterone/cortisol(C)from the group of common loss of weight has obviously fallen(p＜0.05).After the experiment,the numerical value of testosterone from the group of loss of weight with nutrition intervene is apparently higher than that of the other twogroups (p＜0.01).3.The change of immunity index:IgA of the group of common loss of weight has obviously gone down (p＜0.01),and the IgA levels of the other two groups have greatly gone up(p＞0.05);the leukocytotic number of the group of loss of weight with nutrition intervene has obviously increased(p＜0.05).4.The change of physical strength index:the elbow joint and knee joint peak torque(PT)of the athletes from the group of common loss of weight has either risen the least,or fallen the most.From the perspective of nutrition's effects on the peak torque(PT) of elbow joint and knee joint,the group of nutrition intervene superiors to the group of common loss of weight.The most power of both the groups with common nutrition and with nutrition intervene has been obviously increased(p＜0.01).And the fatigue index of the athletes has obviously fallen.Experiment Result:Reinforcing the nutrition such as inorganic salts and vitamins can help athletes prevent from the falling of sports and immunity levels to stimulate human body to return to normal Supplying the compound substances such as glutamine can increase the secretion of testosterone and effectively prevent the resolution of muscular protein to stimulate muscular to grow by which peak torque(PT)and the most power can be increased and body moving power can be improved.
