【摘要】：運(yùn)動(dòng)員選材是體育科學(xué)研究的重點(diǎn)問題,而探求測試手段簡單,準(zhǔn)確性高的運(yùn)動(dòng)選材指標(biāo)是體育科學(xué)研究的熱門問題。運(yùn)動(dòng)員的科學(xué)選材是運(yùn)動(dòng)員取得優(yōu)異運(yùn)動(dòng)成績、攀登世界冠軍寶座最強(qiáng)有力的要素,而籃球運(yùn)動(dòng)員選材又是籃球優(yōu)秀運(yùn)動(dòng)員培養(yǎng)體系中非常重要的一個(gè)環(huán)節(jié)。近年來,在體育科學(xué)選材領(lǐng)域涌現(xiàn)出更多簡單可靠的新指標(biāo)并未在籃球方面得到應(yīng)用。針對(duì)指長比在籃球運(yùn)動(dòng)員選材領(lǐng)域是否能夠運(yùn)用的問題,對(duì)籃球運(yùn)動(dòng)員指長比與運(yùn)動(dòng)等級(jí)及投籃命中率的相關(guān)性進(jìn)行了研究。以實(shí)證研究為基礎(chǔ),豐富籃球運(yùn)動(dòng)員選材指標(biāo),為籃球運(yùn)動(dòng)員科學(xué)選材提供可靠的理論數(shù)據(jù)作為參考。本文選取國家一級(jí)籃球運(yùn)動(dòng)員31名,國家二級(jí)籃球運(yùn)動(dòng)員55名,未達(dá)級(jí)體育專業(yè)學(xué)生165名。通過文獻(xiàn)資料法、測量法、數(shù)理統(tǒng)計(jì)法對(duì)籃球運(yùn)動(dòng)員指長比與運(yùn)動(dòng)等級(jí)及投籃命中率進(jìn)行統(tǒng)計(jì)與分析。操作過程首先是運(yùn)用數(shù)碼相機(jī)采取樣本的指長照片,通過Image-Pro Plus 6.0圖像處理軟件計(jì)算指長。然后用SPSS17.0數(shù)據(jù)分析軟件對(duì)測量數(shù)據(jù)進(jìn)行統(tǒng)計(jì)學(xué)分析。調(diào)查對(duì)象均為來自河北省及河北省周邊區(qū)域的生源,被調(diào)查者年齡為15歲至25歲,生長發(fā)育情況不限,無遺傳性疾病及先天性缺陷和后天畸形。為了避免民族差異的干擾與影響,研究樣本中對(duì)少數(shù)民族進(jìn)行了篩選與控制。研究結(jié)果:1.指長比具有性別差異,同等級(jí)不同性別間,籃球運(yùn)動(dòng)員指長比女性普遍高于男性,而高水平籃球運(yùn)動(dòng)員同等級(jí)間的性別差異不具有顯著性。2.指長比具有等級(jí)相關(guān)性,同性別不同等級(jí)間,男性一級(jí)運(yùn)動(dòng)員及二級(jí)運(yùn)動(dòng)員右側(cè)的2D:4D、2D:5D均小于普通組,差異具有顯著性,女性一級(jí)運(yùn)動(dòng)員及二級(jí)運(yùn)動(dòng)員左側(cè)的2D:4D、2D:5D及右側(cè)的2D:4D、2D:5D、3D:4D、3D:5D小于普通組,差異具有顯著性。3.男性右側(cè)的2D:3D、2D:4D、2D:5D、4D:5D,女性左側(cè)的2D:3D、2D:4D、2D:5D及右側(cè)的2D:4D、2D:5D,滿足運(yùn)動(dòng)等級(jí)的遞增排列趨勢。4.投籃測試得分與男性一級(jí)運(yùn)動(dòng)員及二級(jí)運(yùn)動(dòng)員右側(cè)的3D:4D相關(guān)系數(shù)較高,但是差異不具有顯著性。建議學(xué)者在籃球運(yùn)動(dòng)員指長比與專項(xiàng)運(yùn)動(dòng)技能方面做更多的實(shí)證性研究。2D:4D、2D:5D與運(yùn)動(dòng)等級(jí)呈一定的負(fù)相關(guān)關(guān)系且具有顯著相關(guān)性,并且男性籃球運(yùn)動(dòng)員的相關(guān)系數(shù)要大于女性籃球運(yùn)動(dòng)員,右側(cè)的相關(guān)系數(shù)普遍高于左側(cè),其中以右側(cè)的2D:4D、2D:5D尤為顯著。以運(yùn)動(dòng)等級(jí)來定序運(yùn)動(dòng)能力,研究籃球運(yùn)動(dòng)員指長比與運(yùn)動(dòng)等級(jí)的相關(guān)性,發(fā)現(xiàn)右側(cè)的2D:4D、2D:5D與運(yùn)動(dòng)等級(jí)顯著負(fù)相關(guān),在籃球運(yùn)動(dòng)員選材領(lǐng)域具有一定參考價(jià)值,并且在籃球項(xiàng)目中右側(cè)2D:4D可作為重點(diǎn)研究對(duì)象。
[Abstract]:Athlete selection is a key issue in the research of sports science, and it is a hot issue in sports science to seek the sports material selection index with simple test means and high accuracy. The scientific selection of athletes is the most powerful factor for athletes to obtain excellent sports results and climb the world championship position, and the selection of basketball players is a very important link in the training system of basketball elite athletes. In recent years, more and more simple and reliable new indexes have emerged in the field of sports science selection, which have not been applied in basketball. Aiming at the question whether the finger length ratio can be used in the field of basketball players' selection of material, this paper studies the correlation between the length ratio of finger length and the sports grade and the shooting hit rate of basketball players. Based on the empirical research, this paper enriches the selection index of basketball players and provides reliable theoretical data for the scientific selection of basketball players as a reference. This paper selects 31 national first-grade basketball players, 55 second-level national basketball players, and 165 students majoring in physical education. Through the methods of literature, measurement and mathematical statistics, this paper makes statistics and analysis on the ratio of finger length, sports grade and shooting hit rate of basketball players. The first step is to use the digital camera to take the finger length photos of the sample and calculate the finger length by Image-Pro Plus 6.0 image processing software. Then the SPSS17.0 data analysis software is used to carry on the statistical analysis to the measurement data. The subjects were all from Hebei Province and the surrounding areas of Hebei Province. The subjects were 15 to 25 years old. The growth and development of the subjects were not limited. There were no hereditary diseases, congenital defects and acquired deformities. In order to avoid the interference and influence of ethnic differences, ethnic minorities were screened and controlled. The result of the study was: 1. The ratio of finger length to finger length of basketball players was generally higher than that of men, but there was no significant difference between high level basketball players and high level basketball players. The ratio of finger length to finger length has a grade correlation, the male first class athletes and the second class athletes' right side of 2D: 4D: 2D: 5D are lower than the common group, the difference is significant. The difference of 2D: 4D: 5D on the left and 2D: 4D: 5D: 3D: 4D: 4D: 3D: 5D on the right side of the female first class athletes and the second class athletes is significantly lower than that of the ordinary athletes. 2D: 3D: 2D: 4D: 4D: 4D: 5D: 5D: 5D: 5D: 5D: 2D: 2D: 2D: 2D: 5D; 2D: 4D: 5D; 2D: 4D: 2D: 5D; The score of shooting test was higher than that of male first-grade and second-class athletes, but the difference was not significant. It is suggested that scholars should do more empirical research on the ratio of finger length to specific sports skill of basketball players. 2D: 4D: 2D: 5D has a certain negative correlation with sports grade and has significant correlation. The correlation coefficient of male basketball players is higher than that of female basketball players, and the correlation coefficient on the right side is generally higher than that on the left, especially 2D: 4D: 2D: 5D on the right side. This paper studies the correlation between the ratio of finger length to the level of movement of basketball players, and finds that 2D: 4D: 2D: 5D on the right side is negatively correlated with the sports grade, which has certain reference value in the field of basketball players' selection of talents. And in the basketball project, the right side of 2D:4D can be taken as the key research object.
