Running can cause a side stitch, which is a sharp pain often felt just below the ribs. This is frequently caused by the mechanics of breathing combined with the physical exertion of running.
Here's a breakdown of why this happens, using information from the provided reference:
- Diaphragm Pressure: Rapid, deep breathing during running places downward pressure on your diaphragm.
- Abdominal Pressure: At the same time, the increased abdominal pressure from exertion pushes up on your diaphragm.
- Pinched Muscle: This combination of downward and upward pressure can pinch the diaphragm muscle, resulting in the painful side stitch.
In essence, the rapid breathing associated with running, coupled with the increased abdominal pressure from physical activity, puts a strain on the diaphragm, leading to that sharp, stabbing pain on your side.
