Correlation Between The Testing Concentration Of Human Growth Hormone(hGH) And Out-competition Doping Checking Time

Purpose ofAnalysis:As development and extensively using of human growth hormone recombination, it is also widely and abusively used in competitive sports to enhance athletic ability.The inspection and testing of growth hormone recombination have become a difficult problem in the field of anti-doping research. Currently direct detection method appointed by WADA requires that if concentration of the sample does not reach the limits of required detection, the sample is invalid. And a large number of invalid samples not only make the detect inefficiency, but also lead to the waste of manpower, material and financial resources during the inspection and testing process.Research Methods:Firstly, The paper collected all of our growth hormone doping check and testing data from2009to2012, established the database of china’s out-competition growth hormone checking, and on this basis, The paper analyzed the correlation between the testing concentration of Human Growth hormone (hGH) and out-competition doping checking time through statistical inference and descriptive statistics, looking regularity which to realize to choose reasonable and effective recommendations about growth hormone Competition Testing and inspection planning time.Results:By taking analysis of the testing concentration of Human Growth hormone (hGH) and out-competition doping checking time under the database, it turns out that17o’clock to18,22o’clock to23are the most suitable time to perform out-competition doping checking, and8o’clock to9,12o’clock to14,19o’clock to21are needed to avoid based on the analysis of pass rate of sample concentration, mean of sample concentration and variance of sample concentration.Besides, the objective factors can affect the level of growth hormone concentration values by the comparison, value of sample concentration at different times of growth hormone under the of objective factors coincide with the regularity of time, but it shows different trends under different factors. According to the analysis of the temperature, it turns out that the sample concentration in spring, summer and autumn is relatively high;according to gender analysis,, it turns out that the sample concentration of men is lower, but more stable than the sample concentration of women; according to the motion project analysis, it turns out that the sample concentration of physical type projects is relatively stable, but the sample concentration of skills-based projects is volatile.Conclusion:Above all, The paper recommended that the most suitable time periods of out-competition doping checking time isl7o’clock to18,22o’clock to23, and the checking time should try to avoid8o’clock to9,12o’clock to14,19o’clock to21. Meantime, it also recommended that they should develop targeted checking program for individual athletes based on their own characteristics and combined with various objective factors.
