Research On Kinesiology In Cricket Front Foot Batting And Sole Pressuree Characteristics

The skills of cricket are relatively exquisite and mainly focus on the sideways movement,and require a lot in batting skills.Batsman has only one life,but there are 11 ways for a bowler to defeat a batsman,which requests that a batsman should not only have great skills and techniques,but also have good stamina and a flexible brain.The main techniques include front foot batting,front foot defending,back foot batting,back foot defending,cutting,pulling shot,sweeping shot,etc.Among them,the front foot batting is core of innings,so having a good command in front foot batting is like having a good weapon.Keeping the stability of lower limbs is the only way to ensure the batting quality.We all know that the power is from the feet.Hence,it is important to do research on the details of movement,especially on the specific features of the pressure and power of the sole of the feet.Cricket has developed for more than 10 years China,and there emerge different types of batmen during the progress in which skills gradually become more and more mature.The essay chooses three batswomen in China,conducts analysis on the front foot batting,and gets the dynamics parameter by applying the technology of shoe-pad measuring sole pressure.With the help of three-dimension fixed camera,it obtains the dynamics parameter,and analyzes by adopting the theories of kinesiology and dynamics.The conclusions are as follows:(1)From the curve of feet pressure---time chart,the gravity of B is on the right foot when she is in the preparation stage,and it turns to the right foot when she is prepared for stepping.A and B put their gravity on the two feet and transfer the gravity to the right foot when they prepare to step.During the batting and following stage,B has a good control of the stability of the left foot,while A and C quake slightly.It is suggested that the players practice more and do more training,so that they can improve their lower body strength and balance,as well as stability.(2)During the preparation,C raises the bat backward directly,while A and B raise the bat gradually according to the coming ball.From analyzing the changing angle of C's ankle,it can be found that the angle variation of her feet decreases,and the two feet move outward.It is not good for the moving and stability of players,so in the preparation period,the angle of right ankle had better remains between 0°and 0.15°.(3)In the stepping stage,both A and B have the outward raising movement in the left wrist joint,while C chooses to raise backward directly.The former two can speed up the movement of the bat and strengthen the power of hitting,and the latter can better control the bat,which helps to guarantee that the bat is facing the coming ball directly.(4)By analyzing the angle of hip joint,it can be found that B and C tend to bat the ball in the front,while A has a tendency to bat on the side of the body and bats comparatively later.The advantage of the former two is that batsman can see the coming ball much more clearly,and its disadvantage is that there will exist a horizontal glide as the body turns around.What's worse,it is easy to cause the bank shot when they encounter the breaking ball,or the ball will fly between the cricket board and the leg guard,which will lead to the failure at the wicket.A adopts the method of sideway batting,which guarantees no space or gap between the board and the leg guard,and it guarantees the effective hitting.(5)According to the statistics from the following stage,the three players all have the movement of following by moving forward,which complies with the batting rules.As can be implied from the statistics,C's stepping range is relatively small,but her forward moving range is big,so her angle of left hip joint is smaller than that of A and B.The big range of body's forward moving can offset the disadvantage of batting the ball to the sky when stepping little.
