| This article mainly studies the reasons why China’s high-level young female shot putter Yu Tianxiao improves competitive level within a fixed time.Use the literature method,expert interview method,three-dimensional image analysis method,case analysis method,comparative analysis method,mathematical statistics method to conduct a systematic research on the training content.Among them,expert interviews and actual team data collection are used.Use kinematics 3D images to build a motion model for Yu Tianxiao and obtain important kinematics data.This article set up two kinematics tests during scientific research.Analyze and draw conclusions based on data comparison.The purpose is to fully understand the annual training characteristics,common training methods and load arrangement of young high-level female shot players.Hope to strengthen the reserve force of female shot put in China.Provide reference and data support for the scientific training of young women’s shot put in China.The main research conclusions of this article are:(1)Yu Tianxiao’s 2018-2019 training plan uses dual cycles.And in the preparation period and the competition period,it is divided into different stages in detail.Successfully prepare for the National Youth Track and Field Championships and the National Youth Games.(2)Yu Tianxiao mainly improved the special technology in the 2018-2019 annual training plan.Targeted physical fitness training at all stages.Shot put performance increased by 2.14 meters.The largest increase in the past 5 years.(3)Yu Tianxiao’s various training methods in 2018-2019 training.The process is highly correlated and logical.The practice of each module of physical fitness training is highly directional.This process is trained with the core to improve the quality of special technology.(4)The training content of Yu Tianxiao 2018-2019 training plan is higher than that of high-level athletes.She has more training speed,coordination and sensitivity.Her training is less difficult than a good adult athlete.(5)Yu Tianxiao Improved the reasonability of 2018-2019 Annual Training Shot Put Technology.After training,pay attention to increasing the angle between the two thighs in the back slide and increase shoulder width twist angle.She should increase the range of special technical actions.Shorten the transition time to ensure speed superposition and momentum transfer during slipping for speed up special technical action.(6)Yu Tianxiao’s 2018-2019 training plan detects the lack of sports physiology to support athlete training. |
