Horizontal Discus Velocity cm/s
The resultant release velocities calculated for the best and worst throws performed by the top four competitors were: 3080 (3008) cm/s for Riedel 2718 (3343) cm/s for Dubrovschchik 2599 (2270) cm/s for Kaptyukh, 2498 (2441) cm/s for Washington.
CONCLUSIONS Blocking Action
CONCLUSIONS Body Torsion
Thank you
The projection angles in the YZ plane represents the angle with respect to the horizontal for the best and worst throws were: 22 (30) deg for Riedel 29 (36) deg for Dubrovschchik 37 (31) deg for Kaptyukh 30 (60) deg for Washington.
The heights of release for the best and worst discus throws were : 1.5 (1.4) m for Riedel, 1.8 (1.9) m for Dubrovschchik, 1.6 (1.4) m for Kaptyukh, 1.2 (1.4) m for Washington.
The elapsed times to complete the turns for the best and worst throws were: 3.0 (1.4) sec. for Riedel, 2.3 (1.6) sec for Dubrovschchik, 1.9 (1.1) sec for Kaptyukh, 1.2 (1.4) sec for Washington.
Riedel Best & Worst #1
Dubrovschchik Best & Worst #2
Kaptyukh Best & Worst #3
The combined effect of the projection velocity, projection angle, and height of release resulted in best and worst throws of: 69.4 [OR] (63.1) m. by Riedel 66.6 (59.7) m by Dubrovschchik , 65.8 (63.8) m for Kaptyukh, 65.4 (61.3) m for Washington. The aerodynamic variables of angle of attack and spin were not deter-mined for these throwing trials.
