What you will learn...
Mechanical Advantage
Mechanical advantage, mathematically, will tell who is the
best player.
Knowing how much effort each player expends, how many forces
are created into the joints and how may parts are used will reveal who is the
strongest one with the most endurance.
You will learn how the mathematical analysis is determined to
arrive at the mathematical comparison of proper and improper spinal posture.
Knowing how many muscles must work, how many forces are
created in the form of compression and shear, and how many joints are involved
will reveal who will be the strongest, have the best endurance and be less
likely to get hurt.
You will learn to compare how much true effort is used between
proper and improper posture to perform a movement like a sit up.
You will learn to compare the forces created that can damage
tissue between proper and improper spinal posture when performing a movement
like a sit up.
