An Experimental Study On Skill Transfer Of Javelin Whipping Technique In The Teaching Of Volleyball Spiking Arm Swing Technique

Objective:the volleyball project as one of the traditional "big three" project,in the ordinary university has always been a good conduct.Smash is one of the basic techniques of volleyball and smash technology because of its teaching is more,the decomposition method is one commonly used means of volleyball spiking teaching,the arm stroke is spiking teaching key and difficult,because of the javelin whip and volleyball spiking stroke action exist similarities,if can use the effect of migration between the two technologies of skill,and applied to the teaching for teachers in the teaching of volleyball smash increase efficiency,improve the efficiency of learning for students.The research object and methods:this paper USES the literature material method,experimental method,mathematical statistics methods,such as in yangzhou university volleyball class students as the subjects,it can be divided into the experimental group and control group.Experiment was carried out on the experimental group and control group before reflect spiking handwaving quality related index test,test index selection both hands on the head before throwing medicine balls,one hand badminton throw far,shoulder joint flexibility,handwaving is time.At 13 weeks of spiking handwaving action teaching,the experimental group USES the javelin exercise method,the control group with traditional volleyball spiking handwaving practice method.After the experiment testing index reflecting spiking handwaving quality related collection,statistical analysis by SPSS software,the experimental group and control group data by independent sample t-test analysis,between experimental group and the control way using Wilcoxon symbols of rank and inspection before and after the experiment data.Results:(1)the experimental group and control group after experimental hands before head thrown solid ball scores do not have significant difference,the experimental group and control group before and after the experiment with both hands on the head before the solid ball scores had no significant difference.(2)the experimental group and control group after experimental single hand badminton throw far grades have significant differences,the experimental group before and after the experiment one hand badminton throw far grades have significant differences,the control group have no significant difference before and after the experiment.(3)the experimental group and control group after the shoulder joint flexibility results have significant difference,the experimental group shoulder joint flexibility performance has significant difference before and after the experiment,the control group have no significant difference before and after the experiment.(4)the experimental group and control group handwaving time has significant difference before and after the experiment the experimental group handwaving time has significant difference before and after the experiment,the control group have no significant difference before and after the experiment.Research conclusion:(1)the javelin whipping technique can produce a positive transfer to the volleyball spike swing technique;(2)the traditional volleyball spike practice method has no obvious promoting effect on the volleyball spike swing than the javelin whip practice method;(3)the javelin whipping exercise has a significant improvement on the rapid muscle contraction ability,the strength of fingers and wrists,and the transmission of strength in the case of a large range of motion,so that it has a positive effect on the single-hand badminton throwing ability reflecting the explosive power of the arm swing of the upper limbs,but has no significant effect on the solid ball throwing in front of the hands;(4)in the javelin flagellation training method,the movement range is larger and the muscle elasticity and extension are improved more obviously,so the javelin flagellation training can improve the flexibility of shoulder joints more obviously.(5)the javelin whip practice can shorten the swing time of volleyball spike,so the javelin whip practice can improve the swing speed of volleyball spike more obviously.
