Triathlete´s Nutrition


It is easy to believe that triathletes are well nourished but triathletes’ nutrition is a subject in itself that could change the outcome of performance, injuries and training.  Why are there no black triathletes?  The one from Dominican Republic, Cuevas, has many difficulties finishing a triathlon when competing in a World Cup; and Michel from Cuba has the same problem. Nutrition, education about nutrition and many other issues related to education just as Joseph Stiglitz (Nobel Prize winner) mentions in the interview, in addition to the capacity to provide for such nutrition are the main problems to overcome:  “…if you are accepted to College.  You still have to go to the loops…if you do not go to the right High Schools you cannot do well on the exams… It is cascade of events.”

“In his latest book, The Price of Inequality, Columbia Professor and Nobel laureate Joseph Stiglitz examines the causes of income inequality and offers some remedies. In between, he reaches some startling conclusions, including that America is "no longer the land of opportunity" and "the 'American dream' is a myth."”
A simple Complete Blood Count (CBC) gives us a lot of information and should be performed at least three times a year; assuming that the nutritional requirements are met according to calories used by athletes is not enough.  Timing ingesting the food is as important as calories count and percentage of proteins.  If we get the ferritin level in blood at the same time as the CBC, the information is complete for the purpose of following a well-nourished and educated triathlete.

The timing eating and the amount of proteins need a well-educated triathlete.  This lack of education limits the development of the full physical potential.  I have seen athletes having difficulties following a proper nutrition at the right time just because of lack of basic education.  They are not used to “pay attention to details,” or too stubborn to move. “Eating proteins during the first 10 minutes after finishing a hard workout” or a race is not important for the majority of the triathletes, even though we know that glucose used during the hard workout  (above 87% VO2max for more than 20 minutes) will come from our own proteins by degradation of our own structures like muscles, proteins related to the immune system, etc.  Sometimes such workouts instead of strengthens us, weakens us because we cannot produce messengers (proteins induced by genes) and others proteins ordered by the body via genes after the exercise to strengthen us.  One of our athletes was surprised to see that a teammate in the Mexican Team refused to move forward just because he did not want to, when he could have advantage of listening to the speaker better by just moving forward.  This type of education is the one needed to have an edge over everybody with every move.  Perhaps this is not the education mentioned by Stiglitz but it is implicit when you “go to the right High School” and the right kindergarden, as Stiglitz mentions about the “cascade” that makes a difference between the poor and the rich. In simple terms: “Monkey see, monkey do.” How much protein do we give?  Just 100 mgs of easily available protein as it is in a tuna fish can and an Ensure for a 65-70 kilos triathlete.  There are more expensive proteins as in a recovery powerbar or protein powder; this is in addition to carbohydrates calculated according to calories used during the competition or hard workout, which should be taken immediately after competition or training.  250 calories in 500cc would make the trick.  As I said in another post in this blog.  Of the well-educated heart transplanted patients, just 60% follows doctors’ orders, knowing that they could die if they do not follow them.  In our town, of the patients with tuberculosis, close to 20% follow doctor´s orders as said.  What could we expect of our athletes?



The amount of proteins ingested will depend on the amount of times we hit the VO2max above 87%.  Depends on how much one elevates cortisol (please see: March 19, 2012. TRIATHLON PHYSIOLOGY FOR DUMMIES AND THE TENDENCY TOWARD THE MEAN. Fourth part: cortisol and growth hormone); the hormone that increases the formation of glucose (gluconeogenesis) using our own proteins for that purpose.  It can be several hours after finishing exercising when cortisol comes down, reason why we should increase our protein ingestion up to 4grs per kilo when we do this kind of training, maintaining the caloric balance with carbohydrates.  The more we do this training and tolerate it, the better we become.  A simple CBC with differential and ferritin is enough if we have a well-educated triathlete who counts caloric intake and takes protein according to what is mentioned above.
