Abdominal press

The abdominal press ( Latin prelum abdominale ) is the voluntary or involuntary increase in pressure in the abdomen . The internal pressure in the abdomen can be increased from 1.7 to up to 20 kPa . The abdominal press is used to stabilize the spine during bowel movements , when urinating , in the expulsion phase of childbirth , when coughing , when vomiting and when lifting heavy loads, to a lesser extent also when standing normally, and by experienced singers when developing a room-bearing singing voice (see also voice training ).

The abdominal press is made possible by a closure of the vocal folds , retention of air in the lungs and the contraction of the respiratory muscles , diaphragm , abdominal muscles and pelvic floor muscles .

If the abdominal pressure is strong and the trunk wall is less resistant, hernias (fractures with the escape of organs) can occur.
