My Open Letter to Dr K. Cooper

Dear Dr K. Cooper

Fortunately, in 1986 I read in S-t Petersburg the russian translation of your wonderful handbook "The New Aerobics". With an unceasing admiration of your constancy and devotion to your followers, to everybody, I've read several times this book; it teaches with power, conviction and feeling .Generally, the best and most beautiful things in the world cannot be seen, or even touched ; they must be felt with heart. That's why I sense your guidelines of well-being , both interesting and challenging.
First of all, it gifted me a workable way to achieve new levels of physical competence and personal well-being, although I've already been at this time a lifelong jogger (https://tenep.tripod.com/jogging) In my point, your aerobics system presents a wellness school where the follower is instructed how to protect his body against the ravages imposed by modern life. So, 'fit for well-being' is for me the 'quint essentia' of "The New Aerobics". Now I'm aware of a new life behavioral factor that should be taken in consideration - 'wellness is a lifelong commitment'. What deep sense in Leo Tolstoy's saying -
"until you do what you believe in, you don't know whether you believe it or not"! Now I know unequivocally, that I believe it!
I asked myself: What is more difficult to do? To break your worst health habit like smoking or to create a new best health habit like jogging, walking? For me was the last one, because I never did the first one... This is the reason I'm thinking with conviction of your recommended way: ' it took you five, ten or twenty years to get out of shape. So don't be surprised if it takes you a few extra weeks to get back into shape', (I've reached it in 50 weeks!) 'But don't stop your work out!' It's probably the same as developing good relationship with others: it takes years, but a minute to break them.
Finally, at least, but not the last advantage of "The New Aerobics" is the high professional evaluation of a large collected data by means of compressed tables: fitness testing and categories, age - adjusted exercise charts, aerobics chart pack, etc. Just in this area your book was, for me and undoubtedly not only for me , very inspirational : As a lifelong jogger and engineer I spent long time to create a flexible function to express mathematically the impact of my regular jogging experience on my health and wellness ;moreover, "The New Aerobics" well organized tables of data helped me to find the most appropriate model for the above mentioned function. I'm glad to report you that my son Yuri ( a Ph.D. in radio-physics and computer science ) repeated my way to this wonderful habit earlier than I did and now gains regularly ~ 60 c.p. ('Coopers points')- for week, by means of running a distance of 4 miles in 35 minutes, 4-5 days a week . Certainly, as a father I'm glad and want to express my appreciation to my son for his faith in my ability to produce an appropriate function and in particular, for his ongoing guidance and advice..

So, the function is exponential with a flexible structure and based on the shape of 'Fibonnacci series':
* Exponential - because we deal with non linear issues
(all in the nature is non-linear!) and the derivative - speed of developing - is equal to the function itself;
* Flexible structure - because we deal with a curve that changes the shape itself.
* Based on 'Fibonnacci series'- because these series do have many interesting properties and natural patterns . (The spiral growth of leaves on some trees ,for instance, often exhibit the 'Fibonnacci series'.)
The exponential function with flexible structure can be represented by the formula :
Y = a + b.EXP (c.( X-x0))
Where, Y - the function we explore ( Cholesterol, HDL, Triglycerides, Cholesterol/Hdl, LDL, etc.)
X - The independent variable , argument of the function ( years of regular performing aerobics, collected points, millage in year)
x0 - The middle - argument ( I this case the second argument )
a , b , c - The calculated coefficients of the function .
The function works appropriately and helps to determine the level of correlation between the values of the evaluated data; for instant, the Oxygen Consumption (Y, Ml/Kg/Min) as a function of the distance covered during a 12-minute test ( X, Miles) can be represented by the following FFS - formula ( " The New Aerobics"-table on page 29) :
Y = 14.072 + 24.078 * E(1.24825(X-1.37))

The interpretation of this formula confirms a high level of correlation between the function - Y, the oxygen consumption and the independent value - X, the distance covered during a 12- minute test .
The main purpose for creating 'FFS'- function was to evaluate the real impact of aerobics activity on personal well-being, analyzing the test- results related to the time of regular routines .

Welcome to my 'well-being formulas' for last seven years and the integrated impact index of regular aerobic exercises by means of jogging and walking.

What does the integrated impact index ( Kint) stand for? It means that after seven years of practicing regular jogging and walking, my risk of cardiovascular illness is reduced up to 71 % ! I got older and healthier with no special diet, medicines and medical problems. This is my truly, mathematically formulated health-building action of the training process.
Finally, allow me to express my gratitude to your noble job in the style of the elderly gentleman's letter you used as a prologue to " New Aerobics ": I want to take this opportunity to thank you again and again for your profound hope that became true - your books really serve its readers as a key to health and well-being. Thanks a lot for some special key you gifted me -the key to mathematical evaluation of my "jogging for well-being " (mens sana in corpore sano !) - and I am anxiously awaiting my 77th year. ( I graduated college in my 75!)

Appreciatively,
Petr Tene
