The lines in action in sport -
see Chapter 10. In this photo, the
Superficial Front Line is lengthened and
stretched, the Superficial Back Arm Line on
the right side sustains the arm in the air,
and the Superficial Front Arm Line on the
left side is stretched from chest to thumb.
The Lateral Line on the left side is
compressed in the trunk, and its
complement is conversely open. The right
Spiral Line (not shown) is more shortened
than its left counterpart.
