Hi. My name is José
María Oliva Lozano.
I work as a Researcher
and Lecturer
at Universidad de Almería,
a Spanish University located
in the South of Spain.
Today, we're going to talk
about core muscle activity
during physical
fitness exercises.

This talk is based on
a previous article
that we published in a
highly, internationally
recognized journal,
which is the
International Journal of
Environmental Research
and Public Health.
All the content from
this talk is based
on this article with
me as the first author
and Jose Muyor as
the second author
of the study published
in this journal.

First of all, we
need to understand,
what is the 'core'?
Because the core is
not only the abs.
Many people think that
when we do core training,
we are only exercising
our rectus abdominis,
just the front side of the core.
But the core consists of
several muscle groups.
We have the rectus abdominis
on the front side.
We have internal and
external obliques
on the lateral sides.
Erector spinae,
lumbar multifidus,
and quadratus lumborum
on the back side.
We also have the diaphragm
on the upper side.
Finally, you have
the pelvic floor
and the iliac psoas
at the bottom.
The core is like a box
where most kinetic chains
transfer forces to
the extremities.
It's also known as a powerhouse
because we transfer forces
to the extremities.
