Enter Segment Endpoint Coordinates into a spreadsheet arranged something like the illustration below. Add a column which has segmental length percents. Then using the formula described in the lab, determine each segment's center of mass location.
NOTE: The trunk segment is defined as running from the midpoints between hips and shoulders. To find these points, simply average the proximal thigh positions (hips) and the proximal arm positions (shoulders). In the above spreadsheet, the highlighted cells are the inputs into the formula to find the trunk endpoints (green for proximal, gold for distal).
