The Wind - Unwind Sequence, Torsion Angles In Discus Throwing, Andreas Maheras
The Wind - Unwind Sequence, Torsion Angles In Discus Throwing, Andreas Maheras
Track and Field Faculty Publications
During the process of discus throwing, wound up positions are observed where the upper parts of the thrower and discus system rotate clockwise in relation to the lower parts. In other words, the hip axis rotates clockwise in relation to the line connecting the two feet, the shoulder axis is rotated clockwise in relation to the hip axis and the right arm is rotated clockwise in relation to the shoulder axis. Subsequently, the system unwinds and the upper parts catch up with the lower parts.
Generating Speed - Momentum Analysis In Discus Throwing, Andreas Maheras
Generating Speed - Momentum Analysis In Discus Throwing, Andreas Maheras
Track and Field Faculty Publications
To understand the process of generating the speed of the discus relative to the center of mass (c.m) of the thrower+discus system, we will need to look at the angular momentum of the thrower, the angular momentum of the discus and the angular momentum of the combined thrower+discus system. Although the discus speed is the ultimate goal, one cannot look exclusively on the raw speeds because speed alone does not explain the dynamic relationships between the speed of the discus, the forces made by the thrower on the ground and the motions of the thrower. Essentially, the angular momentum of …

Discus Throwing - Multi Disciplinary Mechanical Applications, Andreas Maheras
Track and Field Faculty Publications
Discus throwing, as all the other throwing events, is, from a physical point of view, a multi discipline event. The discus throwing action is a combination of: Jumping Ability, for the explosive action of the legs during the whole duration of the throw and particularly during the final phase, Sprinting Ability, for the smooth and quick motion across the circle; and finally, Throwing Ability, for the coordinated, efficient and effective application of the greatest force possible on the discus during the final phase. Modem discus throwing technique is a result of both current scientific and empirical knowledge. This is expressed …
