A teleological question: Why do we have fingerprints? For the police? Probably for another function, …which Dr. Scaff may discuss next week.
If you cannot attend the Doc’s Talks on Sundays, all of the information Dr. Scaff covers is in his book, Your First Marathon – The Last Word In Long Distance Running, by Jack H. Scaff Jr., M.D., F.A.C.S.M., available for purchase at the Honolulu Marathon Clinic on Sundays and online at: http://yourfirstmarathon.net/buy-online-today/. If you are traveling, Dr. Scaff would encourage you to get a copy, not because it helps the Honolulu Marathon Clinic, but because Dr. Scaff wrote it due to the fact that he cannot say everything that needs to be said in 10 minutes. There is just a lot of good material in the book (and it is a fun read).
Last Sunday, Dr. Scaff talked about heat exchange, and how when a person’s core temperature starts reaching 104°F – 105°F heat stroke occurs, and untreated it can be 80 percent fatal.
There is also something else that occurs. It was first reported by the Honolulu Marathon Clinic, but now the phenomenon is well understood throughout the running world, and it is called Post-Race Collapse.
What happens in Post-Race Collapse is when someone running a race crosses the finish line, looks great, arms triumphantly raised in the air, walks around for a period of time, and the next thing you know s/he’s unconscious in the First Aid tent, when a few minutes before s/he was a healthy relatively young runner.

Teleology: The science that states everything you have is there for a reason, via evolution, or other factors. E.g. Feet are for running.
A teleological question: Why do our eyes point straight ahead? (This relates to running).
Do you believe that humans are primarily vegans? Carnivores? Or do you believe we are primarily a combination of both?
It turns out man is an omnivore. Omnivores eat both meat and vegetables. Continue reading
Teleology is the science that states everything you have is there for a reason, via evolution, or other factors. E.g. Feet are for running and not for much else. Eyes are meant to see, ears are meant to hear. If someone hits you in the ear you don’t see sharp lights, you hear noise and have pain. If someone pokes you in the eye, you see lights, you don’t hear sounds, and you feel pain.
A teleological question:
Why do our eyes point straight ahead? Think about it, next week Dr. Scaff will give you the answer. Believe it or not, this all relates to running in the long run.
Dr. Scaff talked about heat, how it benefits us, how it hurts us.
Last Sunday Dr. Scaff discussed how to calculate maximum heart rate (200 minus half your age), that when you are at 75% of your maximum heart rate you begin to go anaerobic and burn up oxygen faster than you are taking it in, and that nobody can run a marathon sprinting.
He talked about the Talk Test: The rule is never run so fast you can’t talk, and you never run so slow that you can sing. This validates itself and will work at altitude and everywhere else. As long as you can talk you’re aerobic, when you can’t you’re anaerobic. Continue reading
In the early part of this March (2013) the New England Journal of Medicine published an article on the Mediterranean Diet they said was so significant they had to break the code. The Mediterranean Diet has a lot of polyunsaturated olive oil, vegetables, etc. It made all the news channels.
Dr. Scaff reported that he got the original article and read it and really was not that impressed. Then the summary came out in the summary journals, and they also said it was not that impressive a diet, it had no effect on mortality, …which Dr. Scaff suggests is a good end point: If you don’t live longer, what are you doing it for? The article said the Mediterranean Diet didn’t reduce heart attacks, but it substantially reduced strokes. Continue reading
Because everybody wonders about sprinting, Dr. Scaff talked about how to judge if you are running at the right pace without going through the expense and time of calculating maximum pulse rates, percentage, etc., i.e. the Talk Test.
If you read books on running you will see a lot of complicated formulas to determine your optimal heart rate when you are running, known as “when you are in the zone.”
Basically, heart rate is related to age. As you get older your heart gets slower and then one day it stops. When you are training at 75% of your maximum heart rate, you are going from the aerobic, oxygen burning threshold, to anaerobic or the sprint. Nobody can sprint a marathon, so you have all these pulse rate monitors, etc. to determine your optimal heart rate. Continue reading
