Dear all,
Definition for pennation angle is usually given for planar models and
between linear actuators (typically a tendon and a muscle fiber). This
is a cheeky approximation (i.e., the anatomical reality is much more
complex).
Therefore:
- what about a definition when the model is dealing with 3D data?
Would it be still acceptable to use a linear approach to the problem?
- What would be the method to use when both actuators (muscle fiber
and tendon) are not linear anymore, but curvilinear? What is the
pennation angle in this case?
- Is there any consensus on this topic?
Thank you very much for any help on that topic.
Greetings from Belgium,
Serge
