Sampling rate

[Jernej Camernik]

Hi,

is it important to have the same sampling rate for kinematics and ground reaction forces data when performing inverse dynamics? For instance, I have a sampling rate for kinematics at 100Hz, and force plate data at 1000Hz.

Thank you for your answer.

Best,
Jernej

Dear Jernej:
In my opinion it is usually like this, allowing anyone else to provide more cases.
In my experiment, the sampling rate of kinematics is 100Hz, and force plate is always 1000Hz,
or 2000 Hz sometimes, depending on the setting of your device during the experiment. They are alright for the analysis.

See James' reply.
Hope it helps.

Thank you Jack!
The results from ID look ok, I just wanted to make sure.
