Several times over the last few months, I have mentioned that research has shown that swinging a heavy bat (or adding some weight to your bat) to warm-up while in the on-deck circle before an at-bat is detrimental to your performance. Doing this reduces your bat speed, it does not increase it.
Now, I know many of you are skeptical about that when you saw Major League players doing it. Let me tell you why MLB players are NOT a reference when it comes to the best practices in sports sciences.
Looking forward to your comments…
