It seems to me the point of what Mike wrote in this paper is what he said here:
"I believe we are overdosing on velocity programs.
We are putting a lot of faith into programs being marketed on the internet that have not been validated scientifically to be safe or effective. Again, just to be clear, there are many smart coaches on the internet with great programs. I follow many great minds and really respect what they do. But realize that:
- People are trying to implement these programs on their own without thought or a clear understanding on what is safe and effective. They are not selecting the appropriate dose.
- People are implementing the same velocity program for everyone, often on a team-wide basis, not individualizing the dose for each individual.
- People are getting greedy. Many people think if a 1 lb ball can help them gain 3 MPH, than a 2 lb ball can help them gain 6 MPH! They are overdosing.
We have a very limited understanding of the science weighted baseball, long toss, and other baseball training and velocity programs, but research is starting to come out. Below is what we currently know regarding weighted ball and long toss programs.
If you are going to start a pitching velocity training program yourself of with athletes, you MUST understand the science"
I don't see that he advocates not using any of these training methods, just that at best we all have limited understanding of the science (what little there really is of it).
