In Catalonia, as in elsewhere in Spain
ishing and hunting underwater photographic apnea are well established sports.
They are not spectator sports
but the number of practitioners is very high
Despite the technical and physical
annual death occurs some fishermen and freediving
during these sports.
The vast majority of these accidents
are related with the presence of a syncope during the dive in apnea.
It is a fainting produced by the decreased blood supply
and oxygen depletion available in the brain.
This in the outdoor usually has no consequences,
at sea can produce drowning of the athlete.
would say that 95% of the dead fishing sub. and apnea are due to syncope,
there may be a 5% for those causes of sudden cardiac death or other conditions
in principle, it is almost always young people
18 to 25 or 30 years, healthy
that habitually, make exercise and who are trained
and who are found dead at the bottom of the sea.
These people have made a fit.
Because the causes are known that may cause syncope,
medical experts underwater medicine
always advise that freedivers do not exceed their capacities
and avoid risky situations
To prevent this should not be made apneas deepest level one has,
must not exceed the time of apnea
one is to practice,
and of course, having a partner to watch next
and if there are any issues can help.
The desire to fish more
by get the image of a fish that is more depth,
to overcome any record time without breathing
or go as far possible behaves, often,
wanting to reach the limits of own physical and mental strength.
But the problem is in knowing far as one can get
and what is the margin security of each one.
We all know how deep we are comfortable
and time of apnea we do when we go down and up.
You make a descent to 15 m., looking for a stone,
back up, do 1 minute 30 seconds
and you're comfortable and you doing for hours and days,
this is about your depth, in which you are comfortable.
You can make one to 20 meters, rush at minute 40 seconds or 50 minutes,
but you find that you have forced
therefore not to the point of force,
One very important thing to take account
when making apneas static or when taking a "wait"
diaphragmatic contractions are.
Do not get to have diaphragmatic contractions.
At the time that one is beginning to feel those eager to breathe
those in which the diaphragm want begins to contract,
up to 15 meters above you and you make an effort to arrive.
We also have to think that the nerves,
cold or tired, for example,
these limits can vary
and means to overcome them exposed to severe risk.
Therefore, as safety standard is always requires caution and, especially,
that in each dive has always watching companion.
