## Swimming versus Biking versus Running

### Swimming versus Biking versus Running

I have been following the swimming versus biking versus running
discussions and have found them quite interesting. I have always
awarded points to my workouts according to Dr. Ken Cooper's
Aerobic points system. This provides me with a method of comparing
and grading the efforts in the three sports.

For those of you who don't know Dr. Cooper, he popularized the
term aerobics in the 1960's and published many books that espoused
the value of cardio-vascular exercise including "Aerobics",
"The New Aerobics", "The Aerobics Way", etc. Each of these books
gave tables or formulas for assigning "points" to a workout
with "points" being a measure of energy expenditure. The tables
and formulas were derived from the research he did for the
U.S. Air Force in the 1960's. He addresses many sports, but
emphasizes swimming, biking, and running as the best forms of
cardio-vascular exercise. (We all knew that, right?)

In one of the books Cooper published the following formulas for
swimming, biking, and running:

Swimming ( for distances > 600 yards, velocity = yards / minute ):
points = { [ ( velocity / 4800 ) + 0.005 ] * yards } - 3
Bicycling:
points = ( 6 * miles**2 / minutes ) - 1.5
Running (for distances > 1 mile, velocity > 6 mph,
velocity = ( miles * 60 ) / minutes ):
points = { [ ( 2 / 3 * velocity ) + 1 ] * miles } - 1

So, the point I would like to bring to the discussion is that
the relationship between the sports is not a simple distance
formula like x miles swimming = y miles biking = z miles running.
It is, as one might expect, a function of distance AND pace.

To illustrate this point, I have worked out an example by
equating the formulas. This group lists several twenty point
efforts with all the workouts having the same energy expenditure
according to Dr. Ken Cooper's research:
Swimming:
800 yards in 00:06:57  ( 115 yards per minute )
1200          00:17:09  (  70 yards per minute )
1600          00:35:33  (  45 yards per minute )
2000          01:06:40  (  30 yards per minute )
Biking:
10 miles in 00:27:16  (  22 miles per hour )
15          01:04:17  (  14 miles per hour )
Running:
3 miles in 00:19:30  ( 6:30 per mile )
4          00:38:00  ( 9:30 per mile )
5          00:57:30  ( 11:30 per mile )

I could also list for you the equivalent bowling, tennis, and
golf workouts thanks to the breadth of Cooper's work, but that's
another topic.

What I think would be interesting is to take the formulas and
show how much distance is covered for a given number of points
and a given time period for each of the three sports. WHat I mean
is, for the above 20 "point" efforts, how far would someone go
in 10 or 20 min. THis would show (in Cooper's opinion at least)
an equivalent distance for each. For example, from the above
numbers 3 miles running (19:30) is close to the same aerobic
effort as 1200 swim in 17:09.
I would have tried to do this myself, but Dan's tables looked
so nice that I have much more confidence in his ability to
get this done than mine. (Plus I have to swim in the AM...:-)
