I am a tennis coach, and know how important is the slap motion for the tennis serve. All great tennis players slap the serve, but ironically, there is no teaching method, nor any accessory that can help with the slap motion. So I have built a slap device named Hingeband, which is a hinge applied to your wrist, which increases your wrist flex motion speed. I have been using it in tennis, and I'm asking the question here, if it would be useful for baseball?
I am aware of Baseball added rule 8.02(b) prohibiting pitchers from attaching anything to either hand, finger, or wrist. This accessory is intended for training or practice purposes
There are two benefits from using the wrist accessory in training:
a) Build a memory of powerful and precise pitches, and
b) Build more power in the transverse carpal ligament, over the radius bone at the wrist.
The wrist accessory acts as a capacitor: during practice or training, it loads the wrist with power and your pitching memory with positive data, to be made available and released during official play. In my opinion, players should not practice with bare wrist anymore, as this would be a waste of the opportunity to charge your wrist with power and your pitching memory with positive data.
Also, pitchers should not warm up for the game with bare wrist anymore. Those 40-50 warm-up pitches should definitely be executed with the wrist accessory on, in order to load the pitcher's memory with positive pitching data while saving his arm for the game.
I am looking for opinions from this forum. Thank you.
