We can start a serious discussion on both the usssa softball board members and yourself’s premiss that pitched ball speed from 53 feet instead of 50 feet results in a decreased reaction time for softball pitchers.
We need to have a working understanding of the information and assumptions used in this Toyota study you have referenced.
Can you lead me to this study you have referred to?
It’s kinda hard for me to argue against a study I do not even know is relevant to this discussion. I say that because I find it hard to believe this “study” would have been slow pitch softball specific and included the many variables needed for a fair usssa softball study/evaluation.
As I see it/reason.....when it comes to our disagreement on your groups premiss that increased pitch travel distance reduces pitcher reaction time because of increase pitch velocity ...we need to understand the values put into their calculations.
I will try to calculate my views on this and it goes something like this..please understand it’s been 43 year years since I took a physics/calculus class.
My beliefs are based on a 50 foot rubber, pitch velocity of 30 MPH (and no..I don’t know if that’s the average pitch speed..just a uneducated base number to start with)
1) there is a 50 foot pitch distance consideration of resistance, both upward and downward vertical and air resistance to the horizontal velocity of a pitch needing a 3 foot arc to be legal. I will not attempt to include variables such as weather, temperature or elevation. All of which we know have large ramifications on any actual calculated results.
The considerations being imputed should reduce the initial 30 mph velocity by approx. 12 mph making a pitched ball velocity of 18 mph on contact.
2) pitching from let’s say for debate 55 feet..This is a ten percent increase in distance so ,let’s assume, the new increased initial pitched ball velocity is increased to 33 mph (just a little more the ten percent of the original 30 mph)...with extra distance traveled before contact there will be more resistance (drag)on the horizontal velocity so lets add 10 percent to that (12 mph reduction plus 10% = 13.2 mph reduction)
**a 33 mph initial velocity traveling 55 feet will result in a estimated drag of 13.2 mph which will result in the pitched ball having a velocity of 19.8 mph (33-13.2) upon impact of bat.
That means the difference between these two 50 and 55 distance pitches is +1.8 mph at estimated point of impact to increase in energy of deflection potential (rebound off the bat).
A pitch ball increase of 1.8 mph hitting a bat Traveling at a constant of 100 mph ( an estimate of elite players bat speed) with a ball traveling at 19.8 mph equals 119.8 of impact energy compared to at 50 feet that potential energy is 100 swing speed and 18 pitched ball speed for a total of 118 impact energy. That is a total difference of impact speed (pitches ball and swing speed) of +.98%..
Now comes the fun variables part...pitching from 55 feet instead of 50 allows the pitcher more pitched flight time to back up to get set before the batter hits the pitch.
This should allow the pitcher to set up approx 7 feet deep at 62 feet compared to around 55 feet (while pitching from 50 feet)
That’s a SEVEN foot difference..or..8% > distance reaction time. 8% isn’t a lot..but it is more then enough to make up for a 1.8 mph (.98%) increase in speed of contact.
Coop, I guess you can ask those physicists your referring to to look at my “limited education”... equasions, assumptions and variables to see just how far off they are.
So there is my theory... once again...how about sharing this study the usssa inner circle keeps talking to.. hell..Don jr talked about it 8 years ago..
Yes..... I know this is a looong post but...I want to thank you because this helped speed up the time while sitting on a plan for 16 hours.
I am looking forward to your reply.
