Walking vs. Running?

Its almost the same ur going to burn calories too....the only thing is running burns calories in a shorter time and in less distance

Umm, no.

Running burns about twice as many calories as walking

Here is some information about running calories vs walking calories:
http://walking.about.com/od/calorie1/a/calorieswalkrun.htm

That article presents misleading information in order to defend an ideological position (I.e. Walking is as effective as running). This unfortunately is an all too frequent technique.

The author cites no source (unless I missed it) for the claim that "5 mph walking and 5 mph running burn the exact same calories". According the ACSM, energy prediction equations for walking cannot be used for speeds greater than 4.2 mph because at speeds faster than 4.2 mph, there is too much individual variability in stride length and other biomechanical factors. There is only one very narrow range of speeds where walking can even approach (or exceed) the calories burned when running at the same speed. And those speeds are higher than what 95%+ of population would ever be able to or willing to achieve.

In the interest of establishing correct facts, the evidence clearly shows that the per-mile calorie burns for running are significantly higher when compared to most practical walking speeds.

When someone like the OP asks about "the effect" of walking vs running for them, then one must define "effect".

If one is only concerned about burning calories, then, yes, if you can put in the longer time, you can burn an equivalent number of calories as in your running workout. For fitness training, any benefits will depend on the fitness level of the individual. Someone with a higher level of fitness will not get a training benefit from walking--the intensity just isn't high enough.

That being said, there is the "any movement is better than no movement" position. In the case of the OP, someone coming back from an illness, would be well served by going walking at any speed.

Mostly because you're going 6 mph instead of 3 mph. There is a slight advantage to running in calorie burning. Since there's no such thing as a free lunch you can't go the same distance in a shorter time without expending more energy. For general purposes however you can just equate a certain calorie burn for a specific distance. It takes X calories to move X pounds X miles.

The bold part is incorrect. Different movements have completely different efficiency ratios.
For the same distance you typically burn twice as many calories running as compared to walking.

With running there is a lot of wasted energy as you are constantly "lifting" your bodyweight, your body is constantly rising and falling compared to walking where you are relatively level.

These are very common formulae:
Net Running calories Spent = (Body weight in pounds) x (0.63) x (Distance in miles)
Net Walking calories Spent = (Body weight in pounds) x (0.30) x (Distance in miles)

The MET factor for running is twice that for walking.

For me, c50-60 Cals per mile walking, cf c100 Cals per mile running.
