Did someone have a calculation for each foot gained in stride, what the speed equivalent gain is (given that the pitch is coming from 1 foot closer)?
So if two pitchers are throwing 70mph, and one strides 6ft and the other 8ft, to the batter it appears that the latter pitcher is throwing close to 5mph faster given that they are releasing the ball 2 feet closer to the plate.
This is not accurate. One foot increase in stride does not mean that the release point moved one foot horizontally closer to the plate.
One foot gained in stride length seems to result
This post by Denny Tincher thinks the change is 3mph.in less than 6 inches of horizontal movement of the ball's release point.
One foot gained in stride length seems to result in less than 6 inches of horizontal movement of the ball's release point.
Visualize2 circles with the shoulder as the center. Radius of circle 1 is shoulder to stride foot. Radius of circle 2 is shoulder to wrist. There is no math in my example, I'm not interested in it. Just a visual that depicts how moving outer circle x distance is not the same as moving the smaller inner circle.
This doesn't make sense to me. Using an extreme example, a pitcher with a 2 foot stride vs an 8ft stride. The pitcher with an 8 ft stride is releasing the ball much more than 3ft (6 inches per stride foot, 6 foot difference) closer to the plate than the other pitcher. The one is releasing near the end of the circle and the other one near the rubber.
This doesn't seem relevant. The question is how much a change in the stride length will change the time of the ball to reach the plate.2nd chart on this softball website on reaction time adjusts for stride, as do baseball sites on their calculations. Notice how at 43 ft they assume the average pitcher is at 7 ft, while at 40 ft, they stride 5ft.
