what is the action of the rectus abdominis muscle
We're sorry, an error occurred. The rectus abdominis muscle is located in the front of the body, beginning at the pubic bone and ending at the sternum. It is located inside the abdominal region. The muscle is activated while doing crunches because it pulls the ribs and the pelvis in and curves the back. The muscles are also used when a child is delivered, during bowel movements, and coughing. Breathing in and holding the rectus abdominis in pulls in the abdomen. When this muscle is exercised and layers of fat disappear from the abdomen, the exposed rectus abdominis muscle creates the look of a âsix pack.â Strengthening the muscle also improves performance in sports that require jumping.
What is the function of the rectus femoris muscle? Rectus abdominus is the large abdominal muscle in the center of the abdominal region. It controls pelvic tilt. The internal and external obliques are the abdominal muscles located adjacent to the rectus abdominus. The internal oblique stretches from the front of the abdomen to the back of the torso and aids in performing certain body functions such as breathing.
