Absolute Force and Rate of Force Development

What Is Absolute Force?


Absolute force, also know as absolute strength, is the most amount of force one can produce with no limit to the amount of time required to produce the force. Highest levels of absolute force can only be reached during an isometric or eccentric contraction. However, because an isometric contraction requires no lengthening or shortening of the muscle fibers(actually extremely minuet changes in length) and no movement of the limb it is not very practical to use (hard to quantify) and neither is eccentric maximal force due to the supra-maximal requirements (again, hard to measure). Instead, in this article absolute force will be synonymous with maximal concentric force. Absolute force can be measured by using a one-rep max. In such a case, the limiting factor in completion of movement will be the concentric force of a movement, not a single muscle group.
