Uit de worpen in de opwarming blijkt wel dat ik ietwat vooruitgang boek. Dat het aanglijden vanop voorvoet naar hiel gaat... dat hoor ik voor het eerst. Soit, veel moet nog beter. Echt wel iets lager en meer gesloten blijven.
Extract uit: Critical Factors In The Shot Put
It is sufficient to know that release velocity and release angle exhibit a strong inverse relationship. That is, for any given thrower, as one of the parameters increases, the other decreases. Keeping this in mind, it should be obvious that one the simplest ways to increase the release velocity, and thus measured distance, is to manipulate the release angle so that it maximizes release velocity while still maintaining an angle that will permit elite-level distances.
Increased Release Velocity
Release velocity is undoubtedly the most important factor in determining the distance of a throw. Release velocities in excess of 13 m/s are necessary for elite-level throws. As such, all attempts should be made to maximize release velocity.
This recommendation however must be made with the caution and advice that increasing either the athlete or the implement velocity at one phase of the throw will not necessarily increase velocity at release. In fact, HPP research has indicated that the opposite may be the case. This is most likely due to the fact that increasing velocity prematurely can result in instability, technical problems, decreased muscle loading, or inefficient sequencing of muscle contractions.
The primary importance of release angle is its effect on the release velocity. As long as the release angle is within a range permitting elite-level throws, it should be optimized to enable greater release velocities. In so doing, the measured distance will be greater.
HPP research has indicated that for humans the release parameters are optimized when the angle of release is between 31° and 36°. This is considerably lower than the mathematically "optimal" range of 40° to 43° for elite throwers determined by using the projectile motion equation.
While it is impractical for coaches and athletes to aim for exact release angles, it is important to know that lower release angles are actually advantageous as long as they still permit elite-level throws-and that the mathematically optimal release angles will more than likely result in decreased throwing distances.
