The issue with intramuscular emg is that the recording area of the electrode is too small to track recruitment from an entire muscle. You can look at recruitment properties of a handful of MU but not all of them at once.

Hmm interesting. What do you think about those studies I posted though? They seem ok but I'm keen on your thoughts about varying exercises

Squads!

You can definitely change activity* in various prime movers by optimizing position of the body, but just as a rule of thumb you have to be careful in interpretation of surface EMG studies.

For example, the biceps brachiI will likely never be truly fully active in a neutral position because you need to supinate to get the muscle to shorten fully.

Activity* used to say recruitment before however recruitment is not an accurate term in all muscles. Some muscles finish recruiting all of their motor units at 40 to 50 percent MVC and generate the rest of their torque through rate coding. Some have a much wider range of recruitment thresholds.

What is MVC? And what is rate coding? And what muscles are those?

Srs tho what accessories u like m8

Max voluntary contraction, synonymous with 1rm of a single muscle rather than a bunch in a complex movement.

Rate coding is the rate or frequency at which a motor unit fires. The faster the frequency, the more torque that unit produces, up to a plateau.

Big muscles like the quads, triceps etc will recruit mu all the way up to peak torque. Small fine motor control muscles are likely to max out recruitment early and then control torque only through rate coding (allows for much more precise regulation of torque)
