Treadmill Performance Predicts Mortality
An anonymous reader writes: Cardiologists from Johns Hopkins have published an analysis of exercise data that strongly links a patient's performance on a treadmill to their risk of dying. Using data from stress tests of over 58,000 people, they report: "[A]mong people of the same age and gender, fitness level as measured by METs and peak heart rate reached during exercise were the greatest indicators of death risk. Fitness level was the single most powerful predictor of death and survival, even after researchers accounted for other important variables such as diabetes and family history of premature death — a finding that underscores the profound importance of heart and lung fitness, the investigators say." The scoring system is from -200 to +200. People scoring between -100 and 0 face an 11% risk of dying in the next decade. People scoring between -200 and -100 face a 38% risk of death within the next decade. People scoring above zero face only a 3% chance or less.
Oh, you are free to not do it, but unless you do the bank, the insurance company won't accept you as a customer. Also, since the HR department doesn't have good data on your health you are sketchy and you won't get a job.

Does the daily treadmill at the office also count?

Sounds like the best way to prolong your life is to avoid treadmills
politicians are like babies' nappies: they should both be changed regularly and for the same reasons
I presume you mean 183.
The paper is paywalled but assuming they are using 220-age as MHR:
183 is 105% of MHR at 45.
Running on a treadmill has MET of 7-8 (Wikipedia)
105+8*12-4*45=21. i.e. your score is positive which puts you in the 3% chance of dying in the next decade group.
God said, "div D = rho, div B = 0, curl E = -@B/@t, curl H = J + @D/@t," and there was light.
Communism only relates to the way you organize your economy.
The point of this research is probably to allow doctors to make better estimates as to when a patient might die.
Capitalism can be just as bad as communism if you don't regulate the economy. You need some of both.

Spriometry is used by respirologists to basically measure how much air you can suck in and then blow out (among other parameters like lung inflation, exhale velocity, etc.). It was essentially invented around 1846 by John Hutchinson who believed its best use would be by the insurance industry as this volume was strongly correlated to premature death -- the less air you can blow out, the less time you have left! Hence the name for this quantity that we still use in medicine today: vital capacity.
"1846 The water spirometer measuring vital capacity was developed by a surgeon named John Hutchinson. He invented a calibrated bell, inverted in water, which was used to capture the volume of air exhaled by a person. John published his paper about his water spirometer and the measurements he had taken from over 4,000 subjects,[2] describing the direct relationship between vital capacity and height and inverse relationship between vital capacity with age. He also showed that vital capacity does not relate to weight at any given height. He also used his machine for the prediction of premature mortality. He coined the term vital capacity, which was claimed as a powerful prognosis for heart disease by Framingham study. He believed that his machine should be used as an acturial predictions for companies selling life insurances"
Hey mate, spare a sig?
You don't understand statistics
Peer-reviews on everything I write below are greatly appreciated. I want to make sure I understand this equation.
io9 has a pretty down-to-earth explanation of the equation:
FIT Treadmill Score = %MPHR + 12(METS) - 4(age) + 43(if female)
You can get your MPHR for your age here. I found a chart of METS here for various exercises.
So, if I'm understanding this correctly. If I reach a 160 heart rate out of 179.0 MPHR predicted for my 41 years of age while running 12 minute miles worth 8.5 METS. My score would be:
83.7 + 12(8.5) - 4(41) = 21.7
The same heart rate for my age running 8 minute miles:
83.7 + 12(8.5) - 4(41) = 69.7
If I am understanding this correctly, it really looks like you could easily improve your score with a few lifestyle choices (push yourself harder when you work out, eat healthier). This equation could be a great metric for people concerned about their health

Who'd a thunk?
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.
Inconceivable!
None of them can see the clouds; The polished wings don't care.
I assure you, in my line of work not only does HR not want care about your long term viability, it sure as hell doesn't want you taking time off work* to be at the gym. They'll happily juice your husk until it can no longer serve the shareholder and toss it out in the new Environmentally Friendly (TM) Compost Heap. Given the endless legions of unemployed and the opportunity to tap the limitless H1-B market, they're guaranteed to have employees!
*By time off work I mean any point in a 24 hour day.
Don't we already know that female's are more likely to live longer with no clear identifiable cause beyond they are female?
This is unfair discrimination against males. If women can demand equal salaries, we should be able to demand equal lifespan.
If you are not allowed to question your government then the government has answered your question.
