Hi smgcmg,
Thank you for an interesting question.
From an article in American Fitness: "Treadmills vs. elliptical trainers"
http://www.findarticles.com/cf_dls/m0675/4_20/90924125/p1/article.jhtml
"Treadmills and elliptical trainers rank as two of the most popular
machines in gyms today, but which one offers better results? According
to Thomas Altena, professor of nutritional sciences and exercise
physiologist at the University of Missouri-Columbia, the difference
between the two is minimal.
When Altena measured oxygen retention, lactic acid build-up, heart
rate and perceived exertion, he discovered slight differences. "In
this study, the physiological responses associated with elliptical
exercise were nearly identical to treadmill exercise," Altena says.
In two sessions, subjects exercised on each machine at the same
intensity in terms of oxygen consumption and calories burned. On a
rating scale from 6 to 20 (6 being at rest and 20 being at maximal
effort), the sample group rated 13.42 on the elliptical trainer and
12.32 on the treadmill.
"In light of the small statistical differences, a practical
application of this research would state that both exercise machines
are effective for increasing the amount of calories burned and
producing cardiorespiratory, health and training benefits," concludes
Altena."

ASK THE FITNESS PRO A "burning" question By Dan Strayton
http://209.15.46.229/fitnesspro/news/59.shtml
"I noticed that I seem to burn more calories on the elliptical
exercise machine versus when I use the treadmill or bike. Are these
machines accurate? Which exercise actually burns the most calories? --
Just Wondering, Mt. Airy
Dear Just Wondering,
The number of calories you burn while exercising is based on a number
of factors including the intensity and duration of exercise, the
method of exercise (treadmill vs. elliptical), your gender and your
normal metabolism. The reason you seem to burn more calories on the
elliptical machine may be probably related to the fact that that
particular exercise is more intense than your exercise on the
treadmill.
Think about how hard you feel you're exercising on the elliptical and
then compare that to how hard you feel you're working when you walk on
the treadmill. My guess is that you work harder on the elliptical
because, even at its lowest level, it is more difficult than the level
of walking you do. If you elevated the intensity of your walking to
the intensity you experience on the elliptical, you would burn just as
many, if not more, calories. It's all about the amount of effort you
put into the exercise."

"Tired of the treadmill? Sick of cycling? Need a cardiovascular
workout that gets you in shape without being hard on your knees? Then
elliptical exercise machines may be ideal for you.
Elliptical machines, also called ellipticals, elliptical fitness
machines, elliptical cross trainers, elliptical gliders and elliptical
exercisers, offer people a low-impact exercise. Ellipticals,
appropriate for all fitness levels, maximize the time spent exercising
while minimizing wear and tear on your joints. Using ellipticals is a
great way to add to or improve your cross-training workout. Best of
all, ellipticals add variety and may keep you motivated if you are
bored with your current fitness routine."
[edit]
How many calories do you burn on ellipticals?
"Manufacturers claim that you can burn as much as 720 calories or more
per hour when using their elliptical machines. While the exact amount
depends on many factors, elliptical machines burn calories at a rate
similar to moderate-to-vigorous use of a stationary bicycle, treadmill
or cross-country ski machine."

Treadmill Exercise - Calories Burned
http://www.calorie-counter.net/treadmill-calories-burned.htm
"Burning Calories Using a Treadmill
Treadmill workouts are highly effective for burning calories and
improving your cardiovascular system. Treadmills work the large
muscles in your body.
How Many Calories Burned Using Treadmills
According to a study done by the Medical College of Wisconsin and the
VA Medical Center in Milwaukee, the average number of calories burned
during a 60-minute workout on a treadmill is 785 calories."
[edit]
Exercise on a Treadmill
"Running, jogging or walking are all possible types of exercise on a
treadmill. Whether you are a casual walker or a serious runner, a
treadmill is ideal. You can alter the speed and incline to suite your
desired cardiovascular goals."
===============================================================================
Elliptical Trainers
http://www.pilatesinsight.com/fitness-equipment/elliptical-trainers.aspx
For those who prefer a low-impact cardio workout, elliptical trainers
(sometimes referred to as cross-trainers) are a good option. A recent
University of Mississippi study found elliptical trainers capable of
burning up to 550 calories per hour.
Combining elements of the cross-country ski machine, stair climber and
exercise bike, these elliptical trainers are like treadmills where
your feet never leave the ground. You use a gliding motion to swing
your legs back and forth, pedaling in an oval shape to raise your
heart rate without jarring your joints or straining your muscles. Some
models can be adjusted for more of an up and down stair climbing
motion as well as moving along the elliptical path. Most include
moving handlebars for a concurrent upper body workout.

An interesting comparison between treadmill and elliptical trainers -
Burn 300 Calories in 30 Minutes:
http://exercise.about.com/cs/cardioworkouts/a/burn300calories.htm
Treadmill
Start with incline at zero and speed at a comfortable pace (walking or
jogging). Perceived Exertion (PE)=Level 5 (see Perceived Exertion
Scale).
1 Minute: Raise incline one or more percent every 15 seconds. PE=5-6
1 Minute: Reduce the incline one percent every fifteen seconds. PE=6-7
3 Minutes: Walk or jog at a steady pace. PE=5
Repeat entire cycle for 30 or more minutes
Approximate calories burned: 320 (based on 140 lb person)
Elliptical Trainer
Using manual program, enter workout time as 30 minutes and choose
appropriate level
6 Minutes: Set ramps (if option) and resistance levels at medium level. PE=5
2 Minutes: Set ramps at highest level and increase resistance every 30
seconds. PE=6-8
2 Minutes: Lower ramps and resistance to comfortable level. PE=5
6 minutes: Set ramps and resistance to medium and go backwards. PE=5-6
Repeat entire cycle for remaining time
Calories Burned: 250-300 (based on 140 lb person)
