Muscle weight as it realates to velocity


#1

I’ve heard a general rule of thumb that for every 10 lbs of muscle a pitcher adds, he gains an average of 2mph. Obviously, there are many factors including maturity, flexibility, mechanics ect. if you take a look around at the players you’ve seen or coached, what do you think about this theory?


#2

In general, studies show that higher levels of bodyweight is positively correlated with fastball velocity.

Increasing strength can only be a good thing, but getting bigger and larger for the sake of being bigger isn’t necessarily the best idea.


#3

do you have any of the studies on file? I’ve googled this topic and haven’t been able to find any studies.


#4

It’s relaive to where you gain that muscle and how well you can utilize strength in that area in your throw.


#5

It’s in some papers regarding youth pitchers, but again, it’s a very general statement. Just because kids who weigh more tend to throw harder doesn’t mean increasing your weight is a good idea.

why with a 90 mph fastball? why not just any pitcher?

That statement says there will be a 5% increase in velocity and 90 mph is used as the example.

4-5 mph is about 5% of 90 mph. It doesn’t mean this will only occur in pitchers who throw 90.
