- It only allows our arms to move in a linear direction (straight line) and the throwing patterns are everything but linear. The shoulder joint is the most mobile joint in the body and the patterns forced by the tubing limit and restrict the shoulders movements.
The patterns aren't as important as the blood flow. After all, we warm up to throw. The motions of the warm up need not mimic pitching. These are not drills they are exercises.
- The stress placed on the arm from tubing is greatest when arm is at its weakest. The further your arm gets away from the mid-line of your body, the greater the risk for injury. As the arm moves away from the fence into its most vulnerable position, the tensile strength of the tubing is at its greatest.
Agreed. That's why the tension not be excessive. We aren't power lifting, we are warming and increasing blood flow.
- The tubing is a pain in the neck to attach and it requires the assistance of a fence and cannot be performed in every park or home setting.
If you get the right kind, it secures to anything.
- Tubing is expensive and takes a beating based on the weather and climate in different regions of the country.
It should not be left hanging exposed to the elements. I'm sure no one would advocate leaving weighted balls laying around.
- It’s dangerous because it can snap at anytime, I have seen tubing break on multiple occasions and leave whelps and bruises.
There is danger from using balls that are too heavy as well. Any training aid should be inspected before use and respected during use.
- There is too much grey area in the movement patterns and exercises. If not performed properly, the player is not receiving the benefits. The tubing’s strength changes based on the distance and positioning of the arm and body in relationship to the starting point (fence). By using a weighted ball, the stress remains constant and requires the arm to move more efficiently.
Anything not used properly decreases the benefit. There are 6-8 very good tubing exercises that work each rotator cuff muscle as well as the major surrounding groups. These exercises are not about high stress. After all, we are talking about a little 5 oz ball, we need not be pumped up like Hans and Franz.
