Predictive Validity Of Reaction Time And Ability Of Attention Distribution For Children's Tennis Skills Development

Tennis players of the campaign activities, both physical movement (physical activities) is also psychological activities; the two are unified, psychological activities on the activities of athletes to play regulation, control and leading role. Tennis skills are mainly of the project, the role of psychological factors than physical in nature-based projects more visible and prominent. The topics to children aged 7-10 to study, select reaction time and attention to the distribution capabilities of the three indicators focus on issues:1, Children aged 7-10 reaction time to the development of features;2, 7-10-year-old children's ability of attention distribution development of characteristics;3, reaction time and ability of attention distribution of children aged 7-10 tennis skills development predictive validity of the situation. The results are as follows:1,By gender group, the simple reaction time when the men and women on the same level of accuracy is also in action at the same level of selection reaction time, women better than men; ITN test scores and rating, women better than men. Children 7-10 years old tennis skill levels and the simple reaction time was negative-low correlation(r=-.38,P<.05), and selection reaction time to the high correlation (r=-.686,P<.05). That the sooner the reaction time indicators, tennis skill levels will be higher. After in-depth analysis of relevant draw, selection reaction time and groundstroke depth, groundstroke accuracy, service and mobility for the correlation coefficient, r=-.517(P<.05), r=-.577(P<.05), r=-.770(P<.05),r=-.448(P<.05), the instructions to the faster selection reaction time, the movement of the sub-skill levels will have different degrees of increase.2,By gender group, the ability of attention distribution of men and women at the same level of accuracy is also in action at the same level. From the covariance analysis, the ability of attention distribution of men and women respectively in the division and by the frequent use of non-profit group in hand and no reaction when the target interaction, the level of tennis skills no role or relevance.3,Reaction time and ability of attention distribution of children aged 7-10 predictive validity of the tennis skills, selection reaction time validity of the forecast is superior to simple reaction time, hands-coordination tests reflect the ability of attention distribution predictive validity of the less visible. Whether the use of the hands of non-profit group, the ITN assessment results show that the P value of nearly 0.05.In-depth analysis concludes that the groundstroke accuracy of test results are differences, show that the regular use of non-handed for the accuracy of hitting a tennis placement is very helpful.The results show that the reaction time indicators, in particular the selection reaction time indicators, tennis can be used in the initial selection; ability of attention distribution to track indicators can be used as indicators. The institute come to the regression equation must be empirical research can only be widely used.
