Mechanical training is just one step within a kinetic chain reaction (KCR). They work SPECIFICALLY. However, mechanics contradict human motor pattern sequencing - which works RHYTHMICALLY.
If movement (1) flow, (2) rhythm, (3) tempo, and (4) speed are changed at any point during KCR, the result is a redirection of energy. By breaking down the pitching delivery or swing into its most basic form (energy), we can see the positive or negative effect that mechanical redirection creates
THE MECHANICAL MASKING AGENT
A mechanical step is a robotic step within a delivery or swing. It is singled out by coaches in an effort to improve its movement path. However, this mentality ignores the overall movement PLANE and can potentially harm its timing, sync, and effectiveness within the overall KCR energy flow.
GETTING TO THE ROOT CAUSE
A hitter or pitcher is trying to develop better performance results. They do this by increasing movement efficiencies that will develop higher rates of power, speed, and velocity. By improving muscle power and motor response times, an athlete can outperform the speed of the game. Movement training focuses upon the entire KCR by getting to the root of any ENERGY deficiency or issue.
Mechanical issues are a direct result of energy overloading a joint axis point, fulcrum lever, or body part. This has been proven by Newton, physics principles, and is widely accepted within the kinesiology research world. Evidence of such can be seen in physical therapy, wherein equal and opposite movement planes and body parts are identified for therapy. For example, if the front of a pitcher's shoulder is hurt, PT focuses training upon the back of the shoulder, and vice versa. Energy overloads are the root cause of the aforementioned and VeloPRO training harnesses focus upon aligning these flows to ensure dynamic balance is synced
