The Research Of Age Difference On Speed And Accuracy Of Adolescent Tennis Athletes' Decision-making

The study get going the research ideas from the sports training and sports psychology, and use the previous studies for reference, examined influential factors of tennis athletes' decision-making in different age sect. By analyzing the Adolescent's tennis athletes' pattern of the eye movement in the judgement,as well as the differences of decision-making on speed and accuracy in the situation of the differ information content's, discussed the effect of physical maturity, skill level and knowledge experience, movement situation of adolescent tennis players' decision-making on speed and accuracy.The research designed two experiments: Tests one is the eye moving, using two experimental design; Tests two is the ability of decision-making , using the software "the tennis athlete decision -making's test system", designed two experimental design. Adopting the variance analysis to the experimental result,and according to the results of data analysis, draws the following conclusion:(1) Along with the growth of age, the Adolescent tennis athletes' pattern of eye movement is more effectively, and can be faster and more effectively to gazes at the tennis information , exhibiting to the difference of the index of eye movement, such as Fixation Time,Fixation Duration,Saccade Amplitude.(2) The skill level and information can influence adolescent tennis athletes' decision-making on speed and accuracy. In the situation of the same information content's, the higher skill level have quicker speed, higher accuracy .The information content is bigger, the decision-making speed is slower, the accuracy is lower.(3) Along with the age growth, the adolescent tennis athlete's decision-making speed become more quicker, the accuracy is higher.(4)The difference of adolescent tennis athlete's ability of decision-making in different age sect is "information taking-information processing-taking action," three integrated differences in essencly.The reason including adolescent tennis athletes' physical maturity, strategy, kill level and knowledge experience, movement situation possibly.
