It all depends on the skill level of the girl and usually how long she has been playing. I"d have to say the average is about 70-75. I'm a school coach for 6th graders and i have girls pitching very accurate at 60-65 but they have been playing for a while. Speed doesn't really matter as much as accuracy does.
70-if very good and well trained 90 but realistic around 70-80
The average 14 year old should be able to throw around 55-65 miles per hour.
in highschool between 60-90 mph
To be a teenager you should to 13-19, but do not grow up to fast.
You want the javelin to be going as fast as possible when you release it. If you are running as fast as you can and THEN throw it, it will have significantly higher velocity, and will travel farther.
It's mostly teenager who start, but it's NOT a smart idea.
Between 55 and 75 MPH
really fast
it depends on how fast you throw it and if you can throw strikes i would say from 4'11 or above but you dont have to be tall to be a good pitcher it just helps
As fast as you can throw them ;)
As fast as you throw them...
Depends how fast you throw it
As fast as you can throw it.
throw it and it tells you how fast you throw
If you're 16-18 years old it should be 1.8 or 1.9 seconds
