Core is an English term meaning center or nucleus, and as its name suggests, is the nerve center of our musculoskeletal system, responsible for generating and transferring forces and stabilize the body during our movements.
It can be defined as a muscular box formed by the abdominals in the front, paravertebral y buttocks in the back, the diaphragm at the top and the pelvic floor and pelvic musculature on the bottom. If we go into the detail of what are the muscles that "the muscular box" contains, we would find 29 muscle pairs which help to stabilize the spine, pelvis and the kinematic chain during movement.
In the following images you can see the main muscles to which we refer:

You can find many answers, but we summarize the main functions performed by the muscles of the core:
And if we have not yet convinced you of the great importance of the work of the musculature of core, let's see how it affects our sport:
If in any sport the importance of maintaining the strong core is very relevant, in the triathlon it rises to the cube, since in addition to the main functions of each of the disciplines, we perform rapid and explosive movements of position changes that demand from the central musculature.
So from now on, do not center the work of gym only on the muscles of the extremities and give importance to the work of your nerve center of the movement, it will be the one that helps you in all your sports gestures!
