Comparative Study Of The Teaching Effect Of Swiss Ball Combination Practice Method And Hanging Ball Practice Method

Back and Vietnamese high jump is one of the key teaching items of track and field courses and general courses in physical education major of physical education colleges.How to master the high jump technique quickly and correctly under the condition of limited class times and credit hours is an urgent problem to be solved in current teaching.The back jump is composed of four technical parts: run-up,take-off,air and landing,among which the take-off link is the most important and the core link.The swing technology has a direct impact on the take-off effect.The best take-off effect can be obtained through the coordination of the arm and the swing leg,so the key to the take-off link lies in the swing technology.However,in the current teaching of track and field,most teachers generally lack targeted teaching means in the process of teaching the swing technique of the back jump.Basically,they still use the traditional practice method or more use the lob practice method.In the actual teaching process,the lob practice method has a certain practice effect on the combination of run-up and jump,but the effect on the swing technique is not obvious.And it is easy to cause students to make wrong movements.Therefore,this paper,through the method of literature,expert interview,questionnaire survey,teaching experiment,image analysis,mathematical statistics,and based on the movement characteristics and principles of the swing technology of the back and skip high jump,analyzes students’ mistakes in the learning process.A Swiss ball combination exercise method is put forward to promote the learning effect of swing technique of back jump.The advantages and disadvantages of the lob shot practice method and the Swiss ball combination practice method in the conventional teaching methods of swing technique of the back and Vietnamese jump are analyzed through a comparative experimental study,so as to obtain the optimal practice method and apply it to the teaching of the back and Vietnamese jump to improve the efficiency of students mastering key technical movements and improve the teaching effect and quality.The research results show that:(1)In teaching swing technique,the standard score and technical evaluation score of the Swiss ball combination practice method are obviously better than that of the lob ball practice method,which indicates that the Swiss ball combination practice method,compared with the lob ball practice method,can more effectively promote students to master swing technique of the back and Vietnamese high jump and improve the performance of the back and Vietnamese high jump.(2)Compared with the two practice methods,the practice effect of the lob practice method on the combination of arc run-up and take-off is stronger than that of the Swiss combination exercise method,but the effect on the practice of take-off technology and swing technology is not good,because the beginners do not have a standard grasp of technical movements,and the lob set above the take-off point in the practice,it is easy to lead to too much deliberately touch the lob when taking off.Instead of actively swinging arms and legs to touch the drop shot,it will give beginners certain psychological pressure,resulting in the takeoff brake,slow down the takeoff speed and slow down the swing leg,which will affect the takeoff effect and have a negative impact on the subsequent movement over the bar.(3)Swiss ball combination exercise method is beneficial to improve the height of center of gravity when the take-off leg is off the ground,reduce the Angle between the two thighs when the "reverse step" take-off leg lands on the ground,increase the Angle between the two thighs when the reverse step take-off leg lands on the ground,optimize the joint Angle of the hip,knee and ankle when the take-off leg is off the ground,accelerate the vertical speed of the upper leg swing and the angular speed of the swing leg.The improvement of swing technique and take-off effect is more obvious.In practice design,Swiss ball combination practice method is clever in design,simple in operation,safe and reliable,targeted and effective,especially suitable for beginners to learn the back and skip high jump students.
