Muscle Recruitment Patterns and Discharge Rate

One of the most important philosophical/physiological aspects is to understand the utilization of the discharge rate/sequence. The discharge rate is the progressive recruitment and activation of our motor units within our muscles. In order for an action or exercise to be effective, we must fire from the smallest to the largest motor units. From a anatomical perspective, we should fire our transverse abdominis before we fire our obliques or rectus abdominis. The transverse abdominis is one of the main stabilizers of our core/spine and therefore we must activate it first before we turn on the larger heavier muscles. It only makes sense doesn’t it? If we do not stabilize or brace ourselves for the action before the prime movers (main delivery muscles that will “do” the exercise) are activated then there would be varying degrees of output along with possible awkward delivery of an exercise due to earlier fatigue. This is also true for our hip and shoulder rotator muscles. The stabilizers must be activated first before we can safely perform actions with our larger muscles such as our glutes, quadriceps and hamstrings for our hip, and deltoids and pectoralis major for our shoulders. Therefore, if we have problems associated with “turning on” our stabilizer muscles before our prime movers then we need to promptly address and fix this in order to exercise effectively and efficiently.

The message to take home should be this: If I took away your usual stable base such as standing on you feet and asked you to get on your knees and do the exact same exercise, can you do it without faulty or sloppy movement? In this position, it is much easier to see how the stabilizers are working.
