What exactly is the core?
The core is used to stabilise the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, faeces, carbon-laden air, etc.).
Continence Continence is the ability to withhold bowel movements, and urinary stress incontinence (the lack of bladder control due to pelvic floor dysfunction) can result from weak core musculature.
Pregnancy Women use their core muscles, specifically the transversus abdominis, during labor and delivery.
Valsalva maneuver Core muscles are also involved in the Valsalva maneuver, where the thorax tightens while the breath is held to assist, often involuntarily, in activities such as lifting, pushing, excretion and birthing.
