View Full Version : Pennation angle: 3D curvilinear definition?

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
