Now, there are a lot of numbers here but let's take a look at a few things. On this particular day, her max velocity was a little better, her actual new highest velocity is 75 which was hit on another day.
Increase In Launch Angle
The important thing here is that her average launch angle went from 13 to 30 degrees. The only mechanical changes we made in her swing were posture and swing plane changes in order to create a slightly more positive attack angle to the ball. By doing this you can see how much it made a difference in almost all of her numbers.
There was absolutely no loss in average velocity but so much more gained in AVG distance, MAX distance, batting average, slugging percentage, etc. On a side note, even her ability to work the ball hard to all fields went through the roof.
Launch Angle Zones
As I stated above you must take in multiple factors when trying to get players to understand their “launch angle zone”. This just means what degrees in the air do I have the largest margin for error.
For instance, if her average velocity was only 60mph I would have never asked her to attempt raising her average LA. Those would have just resulted in flyouts. It’s vital to remember the factors that I listed above when implementing LA in your training. Remember that it can change over time as the player gets bigger and more technically skilled but needs to be monitored closely in training.
