maximum muscle activity curve

The “maximum muscle activity” curve under inverse dynamics, what muscle is it for? is it the maximum muscle activity for a specific muscle or for all muscles in the body? How is it arrived at? The online tutorial does not cover this. Can one argue a correlation between the “maximum muscle activity” value in AnyBody and the “maximum muscle force” as described by Rhomert’s curve?

Hi Victor,

The “maximum muscle activity” is the maximum activities of all muscles in the model. It can potentially be representative of level of discomfort in the studies movement.

Deciding about using this variable or just using the individual muscle’s variables in left to the users. In general, muscle activity can be compared to normalized linear-enveloped EMG. Please see this link as well.

Hope this helps.


Thanks a lot Mohammad. I understand. This makes everything clear.
