Functions of The Core
The core is used to stabilize the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, feces, carbon-laden air, etc.).
- Valsalva maneuver
Core muscles are very important in the Valsalva maneuver, which is when a person's thorax tightens while holding their breath. This normally involuntary action can be induced by linking one's hands in front of the chest while standing, and then pulling against the hands without letting go. The Valsalva maneuver assists in lifting, excretion, pushing, and birthing.
- 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 in weak core musculature).
- Pregnancy
Women use their core muscles, specifically the transversus abdominis, during labor and delivery.

Famous quotes containing the words functions of, functions and/or core:
“Mark the babe
Not long accustomed to this breathing world;
One that hath barely learned to shape a smile,
Though yet irrational of soul, to grasp
With tiny finger—to let fall a tear;
And, as the heavy cloud of sleep dissolves,
To stretch his limbs, bemocking, as might seem,
The outward functions of intelligent man.”
—William Wordsworth (1770–1850)
“Empirical science is apt to cloud the sight, and, by the very knowledge of functions and processes, to bereave the student of the manly contemplation of the whole.”
—Ralph Waldo Emerson (1803–1882)
“Avoiding humiliation is the core of tragedy and comedy.”
—John Guare (b. 1938)
