A more complicated explanation put forth by some researchers is that a side stitch is caused by stretching the ligaments that extend from the diaphragm to the internal organs, particularly the liver. The jarring motion of running while breathing in and out stretches these ligaments. Runners tend to exhale every two or four steps. Most people exhale as the left foot hits the ground, but some people exhale when the right foot hits the ground. It is the later group who seem more prone to get side stitches.
Exhaling when the right foot hits the ground causes greater forces on the liver (which is on the right side just below the rib cage). So just as the liver is dropping down the diaphragm raises for the exhalation. It is believed this repeated stretching leads to spasms in the diaphragm. |
