A Follow-up Study On Main Indicators Of Physique And Special Quality For Chinese Tall Youth Women Volleyball Players

In the 1980 s,volleyball as one of our dominant sports,especially the Chinese women volleyball team won "Five consecutive championships".After 17 years,they won twice world championships in 2003 and 2004.And then,there was 11 years until our volleyball players won the 2015 World Cup Championship again.At the 2016 Rio Olympic Games the women volleyball team won the gold medal,"Spirit of Chinese Women Volleyball Teams " has become an indispensable benchmark of era in the Chinese sports field and inspire the spiritual power of the people in our country.Chinese women volleyball team has won the world championship nine times,which is full of ups and downs,so people realize that the training of volleyball reserves' talent is an important cornerstone of sustainable development of competitive volleyball.With the development of modern competitive volleyball,the focus of competition is on the net,who won the advantage over net,is equivalent to gain the initiative.So the requirement for athletic height of modern competitive volleyball is higher and higher,including height and the height of bounce.Volleyball players' “The heighten of stature” is the mainstream and tendency of the modern competitive volleyball's development.In recent years,the selection and training of Chinese women volleyball players are very seriously,a large number of tall youth women volleyball players emerged in the provinces and cities nationwide.Therefore,we can comprehensively understand and analyze the development rules of the main special quality and physique of the tall youth women volleyball players to provide the theoretical reference for the coaches' selection of athletes,excellent athletes and athletic statures in the special quality's training.This thesis mainly uses the methods of literature,investigation,mathematical statistics and logic analysis to follow-up study the physique and special quality of the tall youth women volleyball players for three years to explore the development's regularities of physique and the main indicators of special quality longitudinally,and master the development's features of tall members,in order to provide a scientific basis,which can further improve the method for tall members,to keep the sustainable development of Chinese competitive volleyball and lay a solid foundation.Through the longitudinally follow-up study on 28 tall youth women volleyballplayers' physique and the main indicators of special quality from 2011 to 2013,the results are as follows:(1)Chinese youth women volleyball players as a whole are average age of 15.82 years old,they have a comparative large space for development.The average training period of tall players is 4.37 years,the average training period for non-tall players is 3.51 years,the average training period of tall players is longer than that of non-tall players,indicating that the tall players will reach the "Five-year to be talent" stage immediately.(2)The growth stability of the youth women volleyball players in China,which does not increase with the increase of age and height,is relatively poorer than height,and the weight of the young members in the pre-2011-2013 period is decreasing.(3)There is a certain gap between Chinese tall youth women volleyball players' Quetelet index and the world's outstanding women volleyball players' low Quetelet index which is 440,indicating the tall players' thin stature,insufficient body,non-enough body's circumference,and the tall members' vulnerable point in the quality of strength.(4)Chinese tall youth women volleyball players' mark of the run-up-and-reach grow with the increase of age,in the early stage 2012-2013,the growth of mark is in the peak period.But according to the code of points in the U18 age group in Chinese young volleyball training syllabus.The average scores of run-up-and-reach are between 62 and 77 points for three years.So the tall players' scores are not ideal.This shows that Chinese tall youth women volleyball players' strength of lower limb remains to be improved.(5)In the standing long jump,Chinese tall youth women volleyball players' average scores are 230.11 cm,239.79 cm and 240.36 cm with a growth tendency as a whole.It is the spurt growth period from 2011 to 2013.According to the code of points in the U18 age group in Chinese young volleyball training syllabus,the average scores are only 56 points,68 points and 69 points,indicating that the tall players' explosive force of lower limb and strength of lumbar muscle is relatively weak.(6)In 2013,Chinese tall youth women volleyball player's 30-meter running performance compare with 2011 is dropping,indicating that the 30-meter running performance is not growth with the increase of the age and training years gradually,and the tall athletes' scores of 30-meter running are average lower than non-tall players,indicating that the players' quality of speed is relatively weak.(7)Chinese tall youth women volleyball players' average scores in half of “M” moving are27.38 s,17.45 s,17.59 s for three years,according to the code of points in the U18 age group in Chinese young volleyball training syllabus,only 0 points,18 points and 16 points.And the tallplayer's scores of half of "M" moving average score are lower than non-tall players',indicating that the tall players' quality of the speed and sensitive quality are not so good.It is especially important for tall players,who have the advantage of height,to develop sensitive quality and the quality of speed.(8)About the condition of players,who join the “China National Team”,the developing trend of height,weight,space between hangs,foots and fingers is steady.But the Quetelet index is low comparatively.In the aspect of special quality,30-meter running and half of “M” moving performances are not ideal,the quality of speed and sensitivity is weak,which effect the players' further exploitation of tall stature's advantage.
