Intramuscular coordination is the firing pattern of fibers within an individual muscle.

For example, prior to a ballistic action, there appears to be a silent period in electrical activity at the local muscle. The thought is that such a silent period is a form of neural inhibition that turns off all motor units to make sure that when the action is about to be performed, non are in a refractory state. Thus, allowing for maximal motor unit activation.

Intermuscular coordination has to do with how muscles fire in coordination with other muscles.

 

The green arrows suggest that all muscles have acted together in the most efficient way.

The two green arrows with the red suggest one muscle may not have been properly coordinated during the action and Force was lost.

The question: Is this is a skill or a raw neuro-physiological trait that can be developed without context?

In my opinion, it is 100% a skill. It might be one of the biggest reasons why transfer and carry over from one exercise or movement to another is minimal at times. As movements become more and more complex, the demands on “neural coordination” become higher.

The ability to train and acquire movement skills is critically important. These cannot always be trained in the weight room.
