Technical and mechanical characteristics of discus throw

The authors researched on the balance of the body,rotating moment,effective pass,rotating speed,orbit features of man and discus,timing for exertion and so on.It was revealed that the transfer of body gravity and the position of supporting point are the bases for balance in rotation.The fine tight state of discus,upper limbs,torso and legs is the prerequisite for effective throw.Good timing of exertion can guarantee efficient throw.
