女子标枪运动员最后用力技术和专项运动素质与运动成绩回归分析——以二级水平为例
摘要
近年来我国女子标枪运动成绩逐步上升,多次在大赛中突破原有成绩。标
枪项目是唯一有较长距离助跑的投掷类项目,在项群理论中,标枪被归为体能
主导类快速力量型投掷项目。标枪运动不仅对运动员的体能要求很高,而且也
是一项技术复杂的投掷项目。尤其是助跑与交叉步的衔接技术、最后用力技术
以及运动素质在整个投掷过程中的运用能力,直接关乎到运动成绩的提升。考
虑到我国女子标枪运动的可持续性发展,在面对女子标枪运动员后备人才不足,
标枪运动成绩不稳定的现状下,有必要对中低水平女子标枪运动员做进一步研
究。本研究选取 20 名女子标枪二级运动员作为测试对象,通过对运动员的专项
运动素质、标枪的最后用力技术以及标枪运动成绩进行测试并获取数据,然后
利用相关性分析法、因子分析法以及多元回归分析法,分别对专项运动素质和
最后用力技术与运动成绩的关系进行分析,最后建立多元回归方程,为科学训
练提供指导。
研究结论:
(1)女子标枪二级动动员最后用力技术指标中的出手速度、右脚着地瞬间
身体重心向前速度、左脚着地瞬间身体重心向前速度、左脚着地瞬间左膝关节
角度、初始偏航角以及双支撑时间与标枪运动成绩呈显著性相关。其中初始偏
航角和双支撑时间与运动成绩呈负相关。
(2)最后用力技术指标归类为五类因子,因子贡献率排序为:综合速度因
子>躯干技术因子>支撑角度因子>支撑时间因子>出手角度因子。其中出手
速度、右着地瞬间躯干后倾角、左脚着地瞬间左膝关节角、双支撑时间、出手
角度分别为以上因子中的典型指标。
(3)最后用力技术对运动成绩的预测模型为:
运动成绩=35.404+0.719×出手速度-38.370×双支撑时间。通过运动员的
实际成绩检测该模型,确定可以用来预测女子标枪二级运动员的专项运动成绩。
(4)女子标枪二级运动员专项运动素质中与运动成绩呈显著性相关的有深
蹲、抓举、15 米+15 米跑、三步助跑五级跳、助跑单手投 1kg 实心球五项指标。
(5) 女子标枪二级运动员的专项运动素质归类为四类因子,因子贡献率
万方数据
女子标枪运动员最后用力技术和专项运动素质与运动成绩回归分析——以二级水平为例
排序为:基础力量因子>速度因子>爆发力因子>全身协调因子。其中,深蹲、
15 米+15 米跑、三步助跑五级跳、助跑单手投 1kg 实心球分别是以上四类因子
中的典型专项运动素质指标。
(6)女子标枪二级运动员专项运动素质对运动成绩的预测模型为:
运动成绩=32.306-0.722×三步助跑五级跳+0.910×助跑单手投 1kg 实心球。
通过运动员的实际运动成绩检测该模型,确定可以用来预测女子标枪二级运动
员的专项运动成绩。

ABSTRACT
Recent years has witnessed a gradual improvement of Chinese women’s javelin
performance in competitions. And the previous records have been broken repeatedly.
Javelin is the only throwing project with a long distance run-up. In terms of group
theory, the javelin is classified as a stamina- oriented and explosive movement.
Javelin is a throwing project, physically demanding for athletes and complex in terms
of techniques. The join of run-up and cross-step, the final force, the ability to put
movement qualities into use go hand in hand with sports performance. With the
sustainable development of the women's javelin, insufficient female javelin throwers
and unstable javelin performance considered, it is necessary to do a further study on
the low and medium leveled female javelin throwers. Participants in this study
comprised 20 level two women’s javelin throwers. Data were obtained by testing
athletes’ special athletic qualities, javelin final force and javelin performance. After
that, the relationship between specialized sports quality and sports performance and
the one between final force and sports performance were analyzed by adopting the
correlation analysis, factor analysis and multiple regression analysis respectively.
Finally, multiple regression equation was established to provide guidance for
scientific training.
Conclusions:
(1) The final force of level 2 women’s javelin throwers includes forward release
velocity, COM Forward Velocity at Right Foot Touchdown, COM Forward Velocity
at Left Foot Touchdown, Left Knee Angle at Left Foot Touchdown, initial Side Slip
Angle and Double Support Time which all significantly correlated to sports
performance. Initial Side Slip Angle and Double Support Time are negatively related
to sports performance.
(2) The final force indicators were categorized into five kinds of factors and
these factors were ranked according to the contribution rate of each factor: Integrated
speed factor> trunk technical factors> support angle factor> support time factor>
release angle factor. Among them, release velocity, Trunk backward Angle at Right

Foot Touchdown, Left Knee Angle at Left Foot Touchdown, Double Support Time,
release angle factor are typical indicators.
(3) Performance prediction model of final force was established:Sports
Performance = 35.404 + 0.719 × release velocity -38.370 × double support time.
The model is examined by the actual results of the athletes. The examination
result showed that the model can be used to predict the specialized sports
performance of the level 2 women’s javelin athletes.
(4) Among special Sports Quality of level 2 women’s javelin throwers, snatch,
15 m +15 meter run, standing long jump, three-step run-up land-falling jump and
run-up throw the 1kg medicine ball with one hand are significantly related with sports
performance;
(5) Specific sports Quality of level 2 women’s javelin athletes are classified
into four kinds of factors and these factors were ranked according to factor
contribution rate: basic strength factor> speed factor> explosive force factor>
systemic coordination factor. Among them, squat, 15m+15 m run, three-step
run-up land-falling jump, run-up throw the 1kg medicine ball with one hand are
typical Sport Quality Indicators;
(6) Performance prediction model of special sports quality was
established:Sports Performance=32.306-0.722×three-step run-up land-falling jump+
0.910 ×run-up throw the 1kg medicine ball with one hand.
The model is examined by the actual sports performance of athletes. The
examination result showed that the model can be used to predict the Special Sports
Performance of level 2 women’s javelin athletes.
