<\/p>\nIn my work I try to engage in continuous dialogue between science and practice. From my experience of thousands of hours of coaching I would say that an average trainee has activation deficit. It is more about how large the deficit is than whether it exists in the first place. There are also large differences between muscles groups in activation deficit – some muscles are easy to command to work, while other muscles are almost impossible to get working effectively.<\/p>\n
In addition, the typical endurance type exercise actually increases this activation deficit. This is rather natural and follows from the training specificity principle. Very effective, \u2018simultaneous one time\u2019 motor unit activation is naturally not the best way to go forward in endurance type performance. Although improving activation can paradoxically increase running economy but more about this some other time.<\/p>\n
In the next blog we will examine why muscle activation is important even for fat burning and weight loss.<\/p>\n

Figure 1: Greatly simplified description of the muscle activation. Nervous impulse traveling from central nervous system (cross-section of the spinal cord) via peripheral nerves (motor nerve with its end plates) to muscle fibers. In a maximal performance muscle fibers (hopefully) get activated completely commanded by very frequent nerve impulses. Naturally, there are also a lot of impulses going from the muscle to central nervous system, but those are not shown in this drawing. (Figure: thefreemedicaldictionary.com)<\/p>\n
