When you get down to it, those in our profession, for the most part are working to train "bodies in motion." "Bodies" both figuratively and quantitatively. This concept relates directly to the principles of physics and Sir Issac Newton.
Shouldn't we be asking on a consistent basis, "how does the understanding of these principles apply directly to what I am doing and to the protocols I employ?"
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
- How am I working to overcome inertia?
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
- What is the relationship between force and velocity?
- What planes of motion am I training in, what planes of motion will the athletes compete in?
- Does improving generic force also result in increases in dynamic acceleration? NO, NO, NO!
- If not, perhaps there is more to improving acceleration than just improving 1-RM. Perhaps, there is more to how we develop force potential as well?
III. For every action there is an equal and opposite reaction.
- What we do to the body (forces enacted upon), the body has to be able to withstand.
- There's a vast difference between a point on a plot or chalkboard and the human body.
- Most significant injuries during training don't occur in real-time, rather result from reaction over time.
If you have a few moments, check-out one of Dr. Walter Lewin's lectures. He has a way of illuminating some topics that in the current strength and conditioning climate are seemingly hazy.
