Fish oil for boxers





Boxers may be able to reduce their risk of developing brain damage by taking fish oil
supplements. According to an animal study by American neurologists,
brain cells recover more quickly from head trauma when given DHA, a fatty acid in fish oil.






Ten to twenty percent of professional boxers show signs of brain damage.
According to doctors, psychiatrists and neurologists this is the
consequence of receiving blows to the head. The medical world regularly
calls for a ban on boxing or the introduction of stricter rules. We
reserve judgement on whether trying to forbid everything that vaguely
resembles a risk is a good idea. In any case, people who practise
martial arts are not the only ones who suffer from head trauma.





In the US alone 220,000 people are admitted to hospital with head
wounds. Of those 220,000 cases, 80,000 have lasting damage from their
injuries and 50,000 of them die. Martial arts practitioners form a
miniscule part of this group.















The researchers, working at West Virginia University, wanted to know
whether the brains of people with head injuries recovered more quickly
or better when given fish oil supplements. The brain contains relatively
high amounts of DHA, the fatty acid found in fish oil. This substance
stimulates the growth of brain cells and protects them against damage
and stress too.





The researchers gave a group of rats concussion of the same degree and
then let the animals recuperate for 30 days. Some of the rats were given
a standard diet, some were given 10 mg DHA per kg bodyweight daily, and
yet another group were given 40 mg DHA per kg bodyweight per day on top
of their standard food.





At the end of the 30 days the researchers examined the rats' brain
cells. They were looking for precursors of beta-amyloid precursor
protein [APP] in the axons, the long protrusions at the end of nerve
cells. Beta-amyloid peptides form plaques in the brains of people who
have Alzheimer's or dementia, but they probably also do this in the
brains of people who have received severe blows to the head.




















Sham = rats not given concussion.





If cells become so damaged that they cannot repair themselves, they kill
themselves. When this happens, the synthesis of the suicide enzyme
caspase-3 rises. This is what happened in the brain cells of the rats
that had been given a blow – but it happened considerably less in the
rats that had been given DHA.





If you convert the doses used into the amount needed for a human
weighing 100 kg [for the sake of easy maths] and take into account the
fact that humans' metabolism is slower than that of rats, you arrive at a
dose of somewhere between 100 and 400 mg per day. Most of the cheap
kinds of fish oil contain 10-15 percent of DHA. That means you need to
take 1-4 of the big one-gram capsules a day.





It's not clear whether other omega-3 fatty acids work as well as DHA,
but of all the omega-3 fatty acid molecules in the brain, 97 percent of
them are DHA.
