how does running affect BMR

[brad310]

Im 6' 235, looking to burn another 35 lbs. I have been exercising daily with few exceptions for almost 2 years now...and my weight has maintainted for over a year as I have focused only on strength/resistance traning.

Im starting to add running back in...for cardio right now im just doing barbell complexes and elliptical.

Ive laid out my calories and output...but the BMR is something that is eluding me. If I am VERY active, my BMR is 3500. If I am not active at all, its 2200. The thing is, running for 20 minutes seems to have a greater effect than the 200 calories the treadmill says.

My question is, is 200 calories of treadmill running enough to boost my BMR substantially, or should i still consider my calorie needs at a desk job as 'inactive' in regards to BMR?

Are you setting your weight on the treadmill? Also, BMR is the rate you burn calories without exercise.

At 235# you're burning about 120-130 calories/mile with little or no incline. So, how far are you going in 20 minutes?

I think his question is in relation to after burn from running. Intervals or sprints will have a higher effect on BMR than a normal, steady paced run. From the various literature I've read, intervals gives you a boost for 3-4 hours compared to the 1 hour boost from normal cardio.

I'll let you do the math, but it's nothing significant that you should be accounting specifically for it. (At least for 20 minutes on the treadmill)

Im running 2 miles within the 20 minutes. I start at 6mph and increase it by .2 each lap until 7mph and i run 1 mile at a steady 7. I dont set my weight on it, i just do a quick start.

@Raging, yes...im am referring to the after effects. Sorry if i wasnt clear. Thx for the info on the intervals, i didnt know that.
