Mike O,

Here are the 4 items trainchain is referring to. I would be interested in any references he may have as well.

1. Movement pattern must be exact or as similar as possible to the athletic motion involved.

2. Contraction velocity must be similar to the event.

3. Contraction force must be higher than the event.

4. Contraction type must be the same.

Bacc,
Thanks for the four laws- I'll wait for the references.
