I have
here briefly described the different disciplines in
freediving.
In static
apnea the freediver holds his breath for the longest
time possible under water. Apnea is Latin and translates into
breath-holding and the discipline is termed static because
the freediver is not moving while performing.
Dynamic
apnea is split into two disciplines one with fins
and one without. The goal is to dive the longest distance
possible under the surface. The discipline is called dynamic
because the freediver is moving while performing.
In constant
weight the freediver must reach his maximum depth
and return by his own power. In my mind this discipline is the
purest and most noble form of freediving since no sled or
balloon is used and because it is performed in the sea. The
discipline is called constant weight because the freediver
must have the same weight while descending and ascending.
In variable
weight a sled is used to reach the maximum depth
(max 30 kilograms), after which the freediver swims back or
pull himself up along the rope.
No limits
here all tricks may be used. The freediver dives as deep as
possible by means of a sled and returns with an
air-balloon.
In free
immersion the freediver uses his arms to pull
himself down along the rope. After reaching the maximum depth
the freediver pulls himself pack to the surface. Fins may not
be worn.
More details on rules for the
various disciplines can be found on the homepage of the
International Freediving Federation AIDA.
