Hi All

JJA has made statements on this board that not only misrepresent my work, he also distorts Adair’s principles governing bat speed development as defined in his book.

In an earlier post you (JJA) claimed that I believed that a CHP could only be created by applying THT and BHT. That was a complete falsehood. A CHP is generated from keeping the hands back and allowing body rotation to fling them into a circular path. Applying torque is in addition to developing a CHP.

Now you state “However, I believe the major difference between the two is Jack’s insistence that top hand torque and bottom hand torque are PRIMARY contributors to batspeed, even more so than circular hand path.” – That is equally false. I have never stated that THT and BHT are more important or produce more bat speed than from the CHP. I have always maintained that the basis for rotational mechanics is the CHP. It must be developed first then the batters must learn to apply torque without altering the production of the CHP. The CHP accounts for 50+% of bat speed generated from rotational mechanics.

Many of your statements regarding Adair’s swing model is at odds with what he actually states in his books (first and second edition). We need to clarify if you agree with the actual principles defined by his book.

I need a short concise answer (a simple “yes” or “no) to the following Adair positions. – (1) He states in his book that the body moves forward about 18 inches at 7 mph during the swing. (not before rotation, but during the swing).

JJA, do you agree that the body moves forward 18 inches at about 7 mph during the swing? Yes or no. You can explain the reason for your answer later.

We can move to another of his positions once you give a clear answer to the above question.
