"What is the optimal delivery angle for a javelin throw, and how do factors such as throwing speed, headwinds, tailwinds, and the distance rating of the javelin affect this angle?"
DELIVERY ANGLE The optimum delivery angle is 30 and 36º. The faster the javelin is thrown, the lower the trajectory will be. Strong headwinds require a lower delivery angle and strong tailwinds require an increased delivery angle. Javelins are manufactured according to distance rating. A thrower who throws 50 m requires a javelin, which flies optimally at 50 m, etc. The higher the distance rating of the javelin, the lower the angle of release.
