Does AnyBody include activation dynamics in the muscle modeling?
No. AnyBody is based on inverse dynamics, so it computes the movement first and afterwards recruits the muscle forces to realize it. Inherent to this process is the assumption that muscle forces are available as quickly as they are needed. AnyBody also assumes that the body recruits muscles “optimally”. More precisely, this means that AnyBody makes the muscles cooperate maximally in such a way that fatigue is postponed as far as possible.
