The ratio of the segment mass, COG and radii of gyration in groups 1 to 6.

The following table shows the mean value of the ratio of the segment mass, COG and radii of gyration for each group.

Note:
・The ratio of the segment mass is calculated as percentage of the total body mass.
・The ratio of the COG is calculated as percentage of the segment length measured from the proximal end.
・Tha ratio of the radii of gyration is calculated as percentage of the segment length.
・The origin of the coordinate system for each segment is the center of gravity of that segment. The x-axis is defined as the frontal axis and +x is the direction from origin towards the front of the body. The y-axis is defined as the saggital axis and +y is the dorection from the origin towards the left of the body. The z-axis is defined as the horizontal-axis and +z is direction from the origin towards the head.
