Abstract

Archery is a traditional competitive sports in china，although we have got lots of price in world class games，there still is a long way to catch up with archery power.The fierce competition of modern archery has got the long and high stimulation to athlete's central nervous sys-tem.So，being familiar with the features of brain function is the basic for improving training quality.

With the method of EEG，this study made long-term investiga-tion to the national archery team，mainly including seven researches，obtained the following conclusions：

1.Make comparative research on EEG and BEAMfor the athlete in national team at the later period of winter training later.The result indi-cated：the group of master sportsman got the best brain nervous system function condition and nerve regulation ability.This group of athletes a-dapts to training load of the later winter training period.

2.The monitor to national archery team indicated that，αfrequency band brain electric power value in bilateral the right flank of athlete's pillow area had the declining trend.During the low-load special train-ing stage in winter training，central nervous system will change from excitement to inhibition；EEG indexes had individual difference，we should make systematic trace analysis.

3.The brain electricity αwave can reflect objectively individual brain's physical maturity process，and we can take it as the main index to weight the degree of brain growth and mature degree.When setting a training plan should consider fully elder archery athlete's characteristic，arrange proper training intensity and training rest，meanwhile we should strengthen the use of enthusiasm restoring method；in the index comparison of brain awaken level，power spectrum ratio and αwave moving ahead.

4.In image condition，environment stable mechanism of athlete's nerve system was broken under load states，central nerve system sup-pressant enhanced.Slow wave phenomenon appears at the later time of excessive air exchange，central nerve system suppressant enhanced.The brain function index of pre-competition can be the standard of to eval-uate preparation effect for Beijing Olympic Games of key athletes in na-tional team，also for other athletes.

5.EEG and EPQG technology，using new spontaneous brain elec-trical signal editing pattern，conducts the dynamic tracing research to Chinese elite archery athlete.The purpose of this research is to explore a kind of method for distinguishing pre-competition anxiety and fear feeling of archery athlete.The result showed：two kind of specificity EEG presents difference of times and weakness.

6.Made the test of function，quality，technology and psychology to 173 male and female athletes from national，provincial and municipal archery team，mainly analyzed the features of brain function，estab-lished high-level athlete competitive ability structural model and the selection evaluation criteria，and has carried on back substitution test to the partial athletes.

7.Establishment EEG database of key athletes in national archery team of preparing for the Olympic Games，provide personalization training services for elite athlete.

8.Through seven researches we investigated，five index was found out，these were the key and stable index to reflect EEG features of archery athletes，and αwave difference of top pillow area were qualita-tive index.
