A Comparative Analysis Of The Teaching Methods Of The Straight-type Push Shot And The Traditional Shot Put In The Hip Wide Position

In this paper,the use of literature,observation,comparative analysis and expert interviews,tracking learning Chengdu Institute of Physical Education Luojian teacher on the 2015 Department of Physical Education track and field classes of push the ball with the hip width stance,compared with the traditional Shot Put technique analysis:The traditional Shot Put technique some teaching methods simply imitate the rough route of putting shot,which gradually deviates the shot put s technical principle,separates it from the essence.Push the ball with the hip width stance,which is based on phoronomics and anatomy s principle and follows the naturalness of people,re-regulates the disadvantages appeared in the traditional teaching,emphasized the details.Thus it interlocks the practice before and after,strengthen the teaching s systematic aspect,lows the rates caused by the unscientific actions,highlights the shot s effect and future development.Push the ball with the hip width stance points out that the parallel distance shall be the optimal distance for the individual pelvis width;the vertical axis of the power foot makes a 90 degree angle with the throwing direction,the knee joint being the natural inner buckle;the shank evoluting slightly shall make a 20-30 degree with the throwing direction,which supports the inner side of the forefoot to touch the ground and lays a foundation for the powerful leaning left side support fast formed in the final force step.The traditional Shot Put technique has no straight shot put teaching,the modern one,however,presents in the final force step,the shoulder s horizontal axis shall turn 60 degree,the throwing arm shall revolves with and makes a 30 degree with the shoulder s horizontal axis.which would be the most optimal straight shot put direction and be convenient put the shot with the maximum force.Push the ball with the hip width stance highlights the guiding,balance-keeping and momentum transferring functions of the non-throwing arm during the shot put;pays attention to the gesture,direction and timing of the non-throwing arm during the shot put.There are demands with the power foot and swing leg in push the ball with the hip width stance,Firstly,posing with push is emphasized in the glide shot put.Thus,when the kicking leg swings,the power leg s burden can be relatively reduced.When this moment is properly used,the sliding speed can be accelerated.Secondly,during the coulé,the kicking leg shall consciously swings towards the right below rear of the power leg,giving space to the width of the individual pelvis,the power leg s foot throw a direction with a 90 degree coulé s direction.Thirdly,When the kicking leg pre-swing back to the power leg,the former knee joint must not surpass the latter one.It aims to avoid the excessive swing,breaking the balance.It is not proper to do many pre-swing actions as it can cause unnecessary physical consumption.
