The agreement between reaction-board measurements and kinematic estimation of adult male human whole body centre of mass location during running. There are different possibilities to obtain it, however, I would like to know what's the best method, or the method considered as "gold standard".
Thanks a lot.
Dear Marcelo,
I agree with Dario. anyway, this is a paper compared between methods of Measurements of vertical displacement in running, it maybe help you.

Hi Marcelo,
During running many researchers focus on the lower extremity and pelvis, which may provide errant COM locations through motion capture software. It may be necessary to model the upper and lower extremities as well as the pelvis and trunk to accurately quantify the COM during running. However, many studies have focused on quantifying stiffness or displacement have modeled the COM using the pelvis segment or a surrogate such as a marker on the L5-S1 joint. I'm not certain that a criterion method ("Gold Standard") exists.
Using segmental method and using motion capture data as input data you can estimate COM accurately. I suggest that make a mathematical model by your self (based on a known model like Hanavan Model).
