Help on Smoothing Running-Kinematics Data

[David Daily]

Hello to all BIOMCH-L subscribers,

I'm a master's student working on a research regarding the influences of
fatigue on running kinematics.
We are using a video camera (50Hz sampling frequency) to collect 2D-kinematic
data of running subjects.

Each subject has different running speed and as a result should have
different cut-off frequency for the filter. (And the same for each marker).

I used residual analysis (as in D.A. Winter's book), but this should be
done for each subject and marker which is a huge work :
~20 subjects * 5 markers * 4 tests * 3 (at least) times on each test =
= 1200 (!!!!) times doing the residual analysis...

So is there anyone who can suggest a systematic way to smooth the kinematics'
data with a shorter-simpler way ???

Thanks in advance ( Of-coarse I'll post a summary of the replies )

David.
