【摘要】：女子跳高曾是遼寧省田徑優(yōu)勢(shì)項(xiàng)目,金玲曾創(chuàng)造了1.97米的亞洲女子跳高紀(jì)錄,但繼此之后我國(guó)女子跳高成績(jī)?nèi)遮呄禄?未能保持輝煌成績(jī)。通過(guò)查閱資料發(fā)現(xiàn),多數(shù)文獻(xiàn)僅局限于優(yōu)秀跳高運(yùn)動(dòng)員技術(shù)的運(yùn)動(dòng)學(xué)分析,忽視了我國(guó)女子跳高項(xiàng)目停滯倒退的原因在于后備力量培養(yǎng)問(wèn)題。本文從運(yùn)動(dòng)學(xué)角度出發(fā),針對(duì)遼寧省優(yōu)秀青少年女子運(yùn)動(dòng)員在比賽過(guò)程中存在的技術(shù)問(wèn)題,進(jìn)行動(dòng)作技術(shù)的初期診斷。遼寧省青少年田徑錦標(biāo)賽云集了遼寧省田徑各項(xiàng)目?jī)?yōu)秀青少年運(yùn)動(dòng)員,代表了遼寧省青少年最優(yōu)秀的后備力量。本文選取2016年遼寧省青少年田徑錦標(biāo)賽上獲得女子組前四名的青少年女子運(yùn)動(dòng)員為研究對(duì)象。研究方法采用文獻(xiàn)資料法、測(cè)試法、對(duì)比分析法、數(shù)理統(tǒng)計(jì)法和訪談法。本文通過(guò)分析遼寧省優(yōu)秀青少年女子跳高運(yùn)動(dòng)員的助跑與起跳銜接過(guò)程中運(yùn)動(dòng)學(xué)參數(shù),剖析其存在問(wèn)題,并作出技術(shù)診斷,提出合理建議,進(jìn)而改進(jìn)技術(shù)動(dòng)作,提高運(yùn)動(dòng)成績(jī),為日后訓(xùn)練提供可參考數(shù)據(jù)。該研究創(chuàng)新點(diǎn)在于現(xiàn)場(chǎng)比賽中對(duì)運(yùn)動(dòng)員的動(dòng)作技術(shù)指標(biāo)進(jìn)行收集,結(jié)合影像觀察,分析遼寧省優(yōu)秀青少年女子跳高運(yùn)動(dòng)員目前存在的差異與問(wèn)題,提出改進(jìn)動(dòng)作技術(shù)的關(guān)鍵所在等。研究表明:1.遼寧省優(yōu)秀青少年女子運(yùn)動(dòng)員的克托萊指數(shù)較大,在青少年選材方面應(yīng)更加重視運(yùn)動(dòng)員身高的預(yù)測(cè),控制體重的增長(zhǎng),加強(qiáng)運(yùn)動(dòng)員的一般素質(zhì)和專(zhuān)項(xiàng)素質(zhì)。2.遼寧省青少年女子運(yùn)動(dòng)員在起跳腿離地瞬間的身體重心水平速度和垂直速度具有較大差異,這正是運(yùn)動(dòng)員不同運(yùn)動(dòng)水平的體現(xiàn),速度的提高是其獲得成績(jī)的關(guān)鍵因素。3.遼寧省優(yōu)秀青少年女子運(yùn)動(dòng)員普遍存在起跳腿送髖不積極、放腳不果斷、擺動(dòng)動(dòng)作不到位、擺動(dòng)腿離地瞬間與起跳腿著地瞬間的兩大腿夾角過(guò)小等技術(shù)問(wèn)題。4.遼寧省優(yōu)秀青少年女子運(yùn)動(dòng)員在起跳腿離地瞬間髖、膝、踝各關(guān)節(jié)蹬伸角度距理想值相差較多,從而對(duì)運(yùn)動(dòng)員質(zhì)心騰起的高度造成了影響。5.遼寧省優(yōu)秀青少年女子運(yùn)動(dòng)員在起跳階段兩大腿夾角較小,起跳腿蹬伸距離不足,表明運(yùn)動(dòng)員的踝關(guān)節(jié)力量、擺動(dòng)腿幅度和速度有待加強(qiáng)。
[Abstract]:The women's high jump was an advantage in track and field in Liaoning province. Jin Ling set a record of 1.97 meters for Asian women's high jump, but after that, the result of women's high jump in our country declined day by day and failed to maintain the brilliant result.It is found that most of the literature is limited to the kinematics analysis of excellent high jumpers, and the reason for the stagnation and retrogression of the women's high jump events in China lies in the training of reserve forces.From the point of view of kinematics, this paper makes an initial diagnosis for the technical problems existing in the competition process of the outstanding young female athletes in Liaoning Province.Liaoning Provincial Junior track and Field Championships gathered the outstanding athletes of Liaoning Province track and field events, representing the best reserve force of Liaoning Province.This paper selects the top four female athletes in Liaoning Provincial Junior track and Field Championships in 2016 as the research objects.Methods: literature, test, comparative analysis, mathematical statistics and interview were used.This paper analyzes the kinematics parameters in the process of connecting run-up and take-off of excellent female high jumpers in Liaoning Province, analyzes its existing problems, makes technical diagnosis, puts forward reasonable suggestions, and then improves the technical movements and sports results.Provide reference data for future training.The innovation of this research lies in the collection of the movement technical indexes of the athletes in the field competition, and the analysis of the differences and problems existing in the excellent young female high jumpers in Liaoning Province, combined with the image observation.The key to improve the action technology is put forward.The study shows that 1: 1.The Ketole index of elite young female athletes in Liaoning Province is large, so we should pay more attention to the prediction of athletes' height, control the growth of body weight, and strengthen the general and special qualities of athletes.The horizontal speed and vertical velocity of the center of gravity of the juvenile female athletes in Liaoning Province have great difference in the moment of taking off legs from the ground. This is the embodiment of different sports level of athletes, and the improvement of speed is the key factor of their achievement.Liaoning Province outstanding adolescent female athletes generally have the following technical problems: the hip delivery is not active, the foot is not decisive, the swing action is not in place, the angle between the two thighs is too small between the swing leg and the take-off leg landing moment.Liaoning Province outstanding young women athletes in the take-off leg from the ground moment hip knee ankle joint extension angle from the ideal value is more difference thus the height of the athlete's center of mass raised caused by the impact of .5.The angle between the two thighs in the take-off stage of the excellent young female athletes in Liaoning Province is small, and the distance between the take-off legs and the pedal is insufficient, which indicates that the strength of the ankle joint, the amplitude and the speed of the swinging legs of the athletes need to be strengthened.
