A simplistic, but practical way to calculate total calories consumed is
weight (kg) * distance (km). The amount of time spent only comes into
play depending on the pace at which you can put in the distance. Since
you are walking now, one way to increase your calorie burn in the amount
of time you have is to intensify your workout to cover more distance.
This means going faster. Either walk faster, or (since you posted to
rec.running) start running. Rowing will burn even more calories, so if
you have access to a rowing machine, that's another option. Yet another
option, comparable to running (so long as you keep the intensity up) and
lower impact activity: elliptical training. Cycling (stationary bike
in your gymn) is yet another option, though since it isn't
weight-bearing, it won't yield too much more calorie burn than vigorous
walking. If you do it, try to keep your RPM at 90 or so for a good burn.
Good luck.

I disagree with this. IME, the effort for a given "burn rate" is pretty
consistent across different exercises. At least for running, there is hard
data.

You are going by ballpark numbers,
and I'm very sceptical on these elliptical numbers. For instance, 3
miles on the elliptical at a pace of 6mph burns more calories than 3
miles on the tread mill going the same rate. And the motion is
equal. (using an elliptical that doesn't have arm motion).

What is questionable is the measure of "distance" on the elliptical. What
does "distance" on an elliptical mean ? You're staying in the same place, so
what does it mean to travel "3 miles", or to travel at a rate of "6mph" ?

If they're talking about the backward-distance traversed by the foot-plates,
it will take more energy to cover the same "distance" as with running, because
your strides are shorter (much like walking) and it's harder to maintain a high
cadence a decent runner maintains 180 strides a minute. This is not easy to do
on an elliptical, especially if you have a reasonable level of resistance.

Its all calories. One thing to consider though (and I'm not sure if
you will face this in only a 30 min workout) is whether your reach
that catabolic state where you are burning muscle instead of fat in
the increased workout time.

For someone at his level of fitness, and doing a normal (not endurance athlete)
cardio workload "the catabolic state" is an enormous non-issue. You might as
well ask him to "consider" whether a haircut would help him avoid suffering
excess air resistance when doing explosive squats.

Hello Ig,

Today I reached just over 1000 calories on an elliptical in 65 minutes.
So I'd say that 500 calories burned in 30 minutes will be easy for you to
achieve. My personal belief is the higher impact workout is better than the
walk. Your heart rate is higher and you sweat more getting those nasties
out of your body. You know I do both, but I don't have the time restraints
you have right now. When I start back to work I think I'm going to do the
high intense cardio vs. the walk.

Well, not sure if you think my fitness level is low or high, I want to
remind that I want to do elliptical at the highest exertion level
possible for me.

You're not really "unfit", but you're still at the stage where you can make
substantial all-round improvements in fitness. These micro-optimisations might
matter to athletes who've reached plateaus and are looking for that minute
"edge" in performance, but everyone else is better off ignoring them and
getting the big picture issues right.

I think you're going to have a hard time truly extending yourself to 100%
effort three times a week. But what you're going to find is that there's a
compromise that works (e.g. trade 1% of the calories burned for half the
pain). There are diminishing returns on pain -- there comes a certain point
where it hurts 10 times as much to burn 5 more calories, at which stage you
might as well just have a slightly smaller breakfast.

500 kcals is 500kcals regardless of whether it is expended via running, XC
skiing, swimming, etc.

Paul,

Certain elliptical trainers calories numbers are highly misleading.
Remember they want to sell more machines. For the EFX machines at LA
Fitness a good approx is to take 70% of their calorie figures. That
is 140 "calories" = 100 actual. For our friend able to run an eight
minute mile he may be able to do the same exertion rate - that would
be 3.5 miles x 140 calories/mile (173 lbs) or 480 calories. To
verify, he should take his pulse running 8 mph and maintain the same
pulse on the trainer. frequency - if 8 mph is a "hard" workout it
is wisest to have a day off or an "easy" day after each workout.

sigh Yet more inaccuracies: 70% of 140 = 0.7*140 = 98, so your
"actual" is 2 calories too generous .

Depends on the machine and the person. Ellipticals aren't bad
approximations to running, from what I've seen, so equalling your
running rate of burn is not likely to be too hard. Doing so
by swimming or biking would likely be difficult. Even though it's
possible to meet or exceed running rates of calorie expenditure
(particularly in biking), it takes technique and experience to do
so.

Calories is calories.

Effort level is a much better indicator of equivalences than those
formulae. The formulae all have approximations and assumptions built
in. The Borg scale (no relation) is very helpful for assessing your
effort levels.

If you spend 30 minutes at the same perceived level of effort,
whether it's running, elliptical, ..., then you've probably burned
about the same number of calories. The actual number of calories
probably doesn't match very closely what the machines claim. (I've
noticed a distinct high bias on the machines, 20-50% too high.)

If running 2.8 miles at 7.46 mph represents a race level effort
for you, you'll definitely be toast in short order trying to achieve
that (running or elliptical) 5 days/week.

That mostly depends on your condition and how the calories are
estimated. The better your condition the less the difference
but generally spreading the same amount of work over more time
means more fat is burned and less carbs. It never goes 0-100%
in either direction.

Calories is calories.
