The optimum projectile angle for achieving maximum horizontal range in throwing events is considerably less than 45^o. This is because an athlete can generate a greater projection velocity at low projectile angle than at high angles. The range of projectile is strongly dependent on projectile speed. In sports, the fact is that the projection speed of implement decreases when you throw within the higher projection angle. Shot put has a projectile angle from 26^o to 42^o. Every athlete has a unique speed, angle curve that depends on his/her stature, strength and throwing technique. 

The flight of discus is greatly affected by aerodynamic forces acting upon it. The aerodynamic forces come from the movement of the discus through the air. When in flight, the discus is affected by force of gravity, aerodynamic lift and aerodynamic drag. The stability of discus flight comes from the spin of the discus. Discus has a projectile angle from 27^o- 43^o for maximum range. To achieve maximum distance in Javelin the athlete will have to balance three components-speed, strength and technique. After approach - run of 13 - 17 strides the releasing angle for Javelin has to take into consideration aerodynamic lift and drag. Distance achieved in Javelin depends upon height of release, angle of release and speed of release of Javelin. The optimum angle of releases 26^o to 40^o.
