【摘要】：柔韌素質(zhì)是指人體關(guān)節(jié)在不同方向上的運(yùn)動(dòng)能力,以及肌肉、韌帶的伸展能力.柔韌素質(zhì)對(duì)保證速度、力量的充分發(fā)揮以及保證動(dòng)作的協(xié)調(diào)性、增加動(dòng)作的幅度和防止事故發(fā)生均有重要意義。 現(xiàn)在一般進(jìn)行柔韌性的測(cè)量方法采用的是坐位體前屈進(jìn)行測(cè)量。本研究對(duì)現(xiàn)有的坐位體前屈測(cè)量?jī)x改進(jìn),本儀器在測(cè)量坐姿板上添加了滑輪系統(tǒng),使得測(cè)量坐姿腿長成為可能。選取2009年入學(xué)到2011年入學(xué)的學(xué)生18-21歲的健康學(xué)生,男生分為一組,女生分為一組,對(duì)所有學(xué)生進(jìn)行隨即抽樣測(cè)量。對(duì)各項(xiàng)身體相關(guān)指標(biāo)進(jìn)行記錄。每組選取男女各110人。抽樣對(duì)象為大學(xué)生新生及大二大三學(xué)生,以班級(jí)為單位,隨即抽取健康的男女各105名,總計(jì)210名。男生身高160cm-180cm間、體重50K-95Kg女生身高150cm-175cm、女生體重40Kg-70Kg。采用測(cè)試卡進(jìn)行數(shù)據(jù)記錄。在數(shù)據(jù)收集過程中難免會(huì)出現(xiàn)數(shù)據(jù)記錄錯(cuò)誤,復(fù)查測(cè)試卡并剔除。對(duì)臂長,臥姿角度,臥姿峰肩長進(jìn)行采集數(shù)據(jù)是對(duì)整體坐位體前屈的影響效果進(jìn)行整體與個(gè)別進(jìn)行分析與討論。 我們清晰的發(fā)現(xiàn)男生成績(jī)與測(cè)量成績(jī)顯著相關(guān)的有軀干彎曲角度,坐姿峰肩高,和臥姿峰肩高。3個(gè)測(cè)試項(xiàng)目的可靠性分別為坐姿肩峰高可靠性系數(shù)為0.9261、俯姿肩峰的可靠性系數(shù)為0.9064、彎曲角度可靠性系數(shù)為0.8651。 女生里與測(cè)量成績(jī)相關(guān)性顯著的有俯姿肩峰高,坐姿峰肩高,彎曲角度。俯姿肩峰的可靠性系數(shù)為0.9064、坐姿肩峰高可靠性系數(shù)為0.9261、坐姿肩峰高可靠性系數(shù)為0.9261。 共同點(diǎn)是顯而易見的,它們分別是軀干彎曲角度、坐姿肩峰高、俯姿峰肩高。女生坐姿腿長、臂長呈負(fù)相關(guān)。男生測(cè)量效度成績(jī)成負(fù)相關(guān)的有身高、臂長、坐姿腿長。與站姿腿長、體重?zé)o顯著性相關(guān)。
[Abstract]:Flexibility refers to the ability of human joints to move in different directions, as well as the ability to stretch muscles and ligaments. Flexibility is of great significance to ensure the speed, the full exertion of strength, the coordination of action, the increase of the amplitude of action and the prevention of accidents. Now the general flexibility measurement method is sitting position flexion measurement. In this study, the existing sitting position forward flexion measuring instrument is improved, and the pulley system is added to the sitting position measuring board, which makes it possible to measure the sitting position leg length. Healthy students aged 18-21 were selected from 2009 to 2011. Boys were divided into one group and girls were divided into one group. All students were measured by random sampling. Record the relevant indexes of the body. Each group selected 110 men and women. The subjects were freshmen and sophomores. The class was used to select 105 healthy men and women, a total of 210 students. The height of male was between 160cm-180cm and the weight of 50K-95Kg was 150cm-175 cm and the weight of female was 40Kg-70kg. Use test card to record data. In the data collection process will inevitably appear data recording errors, check the test card and eliminate. The data of arm length, position angle and peak shoulder length are analyzed and discussed as a whole. We clearly found that boys' scores were significantly related to their measured results, such as torso bending angle, sitting position, peak shoulder height, The reliability coefficient of the three test items was 0.9261, 0.9064 and 0.8651respectively. Among the girls, there were significant correlation between the measured results and the height of shoulder peak, the height of peak shoulder in sitting position, and the angle of bending. The reliability coefficient of shoulder peak is 0.9064, the reliability coefficient of shoulder peak height in sitting position is 0.9261, and the reliability coefficient of shoulder peak height in sitting position is 0.9261. The common ground is obvious, they are torso bending angle, sitting position shoulder peak height, bending posture peak shoulder height. The length of legs and arms were negatively correlated with the sitting position of girls. The height, arm length and sitting leg length were negatively correlated with the validity scores of male students. There was no significant correlation with standing leg length and body weight.
