Measure of Health.
What we want to do is develop not an exercise science per se, but a technology of advancing human performance. – Coach Greg Glassman
Coach Glassman unifies fitness and health with this revolutionary new component, a 3D model.
Science is about measurement and prediction. Without measurable, observable, repeatable data concerning the fundamental physical units of kinematics (mass, distance, and time or MKS) there is no science of human performance. This is true of the planets, automobiles, and exercise.
Introduced in this lecture is age. Fitness can be graphed in two-dimensions with duration of effort on the x-axis and power on the y-axis. At each duration, we average your power capacity across a variety of modal domains (skills and drills). This creates a power curve, the area under which is your work capacity across broad time and modal domains (aka fitness).
We can now add a third dimension to this graph, the z-axis, which is age. By reassessing your two-dimensional fitness at various times throughout your life, we graph the form of a solid. The power curve takes on the shape of a plateau or blanket. This three-dimensional graph is a defining measure of health. Health, therefore, is nothing other than sustained fitness.
