Induced Accelerations Analysis issues

[Rodrigo Mateus]

Hi there,

I am a PhD student at the University of Lisbon, and I am currently trying to calculate the individual muscle contribution to ground reaction forces in a side step cutting task.

Unfortunately, I am having some issues regarding the results.

The first image relates to the experimental ground reaction forces, and the second image relates to the constraint reaction forces as a result of IAA.

What I observed is that the main contributor to these results is the velocity, giving the constraint reaction forces such orders of magnitude. And the profile of the constraint forces is also quite different to the experimental forces. The contribution of muscles and gravity are present, however they are very small.

What does the "velocity" results output relate to?

How can I resolve this?

If you want to contact me with any idea, please feel free to email me: rodrigomateus@fmh.ulisboa.pt

Thank you in advance!

Best regards,

Rodrigo Mateus
