RE: Information on Forceplate position

<t>Hi Thor<br/> <br/> Thanks a lot. I found the 'forcepla.cal' in the raw data folder. A trip to google revealed how to interpret the structure of the file. <br/> <br/> ========================================<br/> 1 Forceplate number<br/> 2 Forceplate scaling factor and length and width of forcepla...

Information on Forceplate position

<t>The synchronized data in the 2011 data set specify COP from the force plates in the global coordinate system. Is it possible to get the approximate corner coordinates for the three forceplates?<br/> <br/> I need that information for an automatic algorithm to link the ground reaction force with ei...

RE: synchronization problem?

<r>Hi Kurt<br/> <br/> I have observed this as well. However, it didn't occur to me that it could be caused by a synchronization problem. <br/> <br/> My guess was that the markers were mirrored. So I simply swapped the left and right markers. <br/> <br/> The link below shows a plot of "ground reactio...

Problem with calibration data

<r>Hi<br/> <br/> I stumbled on something in the synchronized data which I can't make any sense of. <br/> <br/> In "jw_2legsquat_1" the medial and lateral contact force seems to highest when the person is standing upright and decrease during squatting. This seems to counter intuitive.<br/> <br/> Here...

RE: Anthropometric data

Hi BJ

You don't need to find anything in particular right now. I was just wondering which anthropometric data the presentation was referring to.

If I need anything I will let you know.

Thanks.

Anthropometric data

<t>Hi BJ<br/> <br/> Slide 38 in the "Competition workshop presentation" states that subject specific Anthropometric data is available from (Reinbolt et al. 2008). <br/> <br/> I found two possible articles.<br/> <br/> Importance of preswing rectus femoris activity in stiff-knee gait<br/> A computatio...
