Activating the Transverse Abdominis Controversy
Two schools of thought regarding the use of the Transverse Abdominis ("TA") muscle.
From the book "Core Performance" written by Mark Verstegan. The below exerpt is from pages 28 and 29. The Catalyst crowd may not be familiar with Verstegan but he is a fairly well respected coach who founded a training facility called Athletes performance which trains NFL players for the combine, and other professional athletes. Here is the exerpt from his book
"Think of the TA as nature's weight belt. It orginates from the lower spine and wraps around and attaches to the ribs, abdominals, and pelvis. When we draw the belly button in toward the spine and up toward the ribs, we're essetially tightening a belt, ensuring the protection of the pelvis and lower back. Your natural weight belt stabilizes the pelvis and supoorts the torso. Whenever movement begins, the TA is the first muscle that fires...If we can learn how to activate the TA, we can rely on nature's weight belt and not wear additional support. "
From the book "Olympic Weight Lifting" written by Greg Everett, page 30. I think everyone on this website is familiar with Mr. Everett's work. Here is his take on the use of the TA muscle.
"It's critical the athlete not "hollow", or suck in the abdominals as many have been taught to do or will believe is correct. If the abdomnals are drawn in , the ase of support is reducted in width, and this is obviously not beneficial. Such a postiion also limits potential internal pressure and consequently stability. We want the muscles activated tightly while keeping the torso as wide and deep as possible, allowing us a broad foundation to support the load. It may help athletes having difficulty with this activation to think of pushing the abs down."
