The Research Of The Method About Handspring Class Diffculty In Cheerleading

Shot put is one of speed strength events. Its movement is required not only to do in a shot time and fast, but also reflects different muscle working characters and movement’s characters in different movement stages. So the main point of strength training in shot put is how to effectively raise the level of shot put athlete’s strength, and how to resort to strength obtained from training to improve one’s achievement.Therefore, the writer put forward his own standpoint to improve shot put athlete’s achievement extensively through selecting direct and valid training methods according to shot put movement structure.This paper takes the Chinese man shot put records maintained, China founded the first breakthrough20metres mark man shot-putter ZhangJiWei research object, by using the method of documentation, expert interview and mathematical statistics and logic analysis and other methods, in the shot put movement strength training biology principle by summarizing the basis, combining with our excellent man shot-putter Zhangji strength training situation, the paper summarizes the shot put motion strength training, to realize common problems by practical experience to the theory of sublimation, think other athletes and coaches pertinence develop strength training to provide the reference.Study concludes:(1) piece of Zhang Enki’s strength training methods mainly Barbell Weight Training, due to the inherent limitations of Zhang Enki training means,a strength training in the presence of the main shortcomings and deficiencies are:application of bench press can not continue to enhance athlete’s special achievement; Barbell Weight Training is not balanced; thigh before and after muscle strength out of proportion.(2) force is a complex, affected by many factors of quality and ability, it is the" complexity" is mainly reflected in3aspects:athlete’s strength training not only need to consider the muscle strength of the genetic attributes, they must pay attention to the training of acquired factors; force development can not only in strength or a certain the strength range; strength training core mission is to give priority to the development of athlete’s" special force".(3) in the period after the strength training, training test scores are stable growth trend, strength and athletic performance is significantly positive correlation, illustrate the power quality or sports performance development has positive simulative effect, scientific strength training are directly driven by a enc sports performance gradually upgrade.(4)Adopt and push the shot put action structure or muscle work in a similar way, the strength exercises for technical control means to consolidate and special scores improve plays an important role; According to the structure of the training project action shot of athletic performance improvement and the technology has good effect to grasp.(5) In the special strength training, especially to the bench press, squat snatch, the training means, they directly affect the movement of shot record. In the special strength training also join all sorts of physical quality and specific needs of the main bridge of. In the training should pay attention to with appropriate flexibility exercises and in strength training after technical imitation, contribute to the rapid development of Special Forces.
