Study On The Selection Index Of Men's Pistol Shooter In Beijing

Objective:This research through the male pistol shooting athletes of Beijing shooting team and no sport specific ordinary young men the same age respectively,including body shape,physical function,physical quality and psychological index test and comparative analysis.The purpose of this paper is to find out the current situation of the selection of the men's pistol shooters in Beijing shooting team,and find out the differences.Methods:In this research,the male shooters of Beijing shooting team and the young men of the same age with no special sports were selected as the research objects.Two groups of body shape indexes were tested,including Quetelet Index,hand length,finger length,span,lower extremity length H;physical quality indexes,including body balance stability,arm stability,grip strength,grip strength,relative range of elbow joint proprioception;physiological indexes,including heart rate and vital capacity;psychological factors including IQ,atd angle,attention stability,temperament.Analysis and comparison of the specific data differences between the pistol shooters and ordinary people with the same age.So as to find out the current situation of the selection of the men's pistol shooter in Beijing City,so as to infer the relevant indicators for the selection of men's pistol shooter.Results:The male pistol athletes' Quetelet Index,grip strength and lower extremity length B had no significant difference between ordinary young man;2.The male pistol athletes Beijing shooting team index finger length,the ratio of the index finger and hand length,refers to the distance and the ratio of the height,lower limb length H and the ratio of the height were significantly higher than that of ordinary young man;3.The male pistol athletes body balance in Beijing shooting team stability,arm stability,relative grip strength are better than ordinary young man;4.The male pistol athletes in Beijing shooting team pistol shooter 70° and 110°direction perception and there was no significant difference between ordinary young man;90° direction perception is much better than the ordinary young man;5.The male pistol athletes in Beijing shooting team athlete's heart rate,unit vital capacity and there was no significant difference between ordinary young man;6.The IQ of male pistol athletes in Beijing shooting team,atd Angle,listening attention and there was no significant difference between ordinary young man;7.The male pistol athletes in Beijing shooting team vision attention is superior to ordinary young man;8.The male pistol athletes in Beijing shooting team main temperament type of slime and sanguine temperament more mixed with general phlegmatic temperament type.Conclusions:1 Body shape,the length of the index finger to the length of the hand(Length of index finger/ Length of hand > 43%),the span to height(span / height > 102%),lower limb length H to height(lower limb length H/ height > 51%)can be used as a selection index;2 Physical fitness,body balance stability,arm stability,grip strength(Perceptual difference < 3.27 kg),Elbow azimuth perception difference under different Angle change,can be used as a selection index;3 Physiological function,heart rate and vital capacity can be used as a reference index for the pistol shooting athletes,but can not be used as the selection index;4 Psychological factors,with a high degree of concentration of the stability of visual attention,mixed temperament type is more suitable for pistol shooting.And should pay attention to the evaluation of IQ,IQ level should be in the medium or above level.5 Quetelet Index,lower limb length B,maximum grip strength can be used as a reference factor shooting athlete selection,but not enough to become a selection index.
