pace vs. distance?

if i jog for one hour at 4 mph or 40 minutes at 6 mph, how does the calorie expenditure differ? i remember hearing somewhere that a mile burns the same amount of calories no matter how fast you run it because the time compensates .
 
the difference comes into what calories are being burned. With a low HR, you are burning more fat ... the higher HR, the more you start burning protein and are getting into the cardio zone.
 
Well I wouldnt say that is all right lol. With higher HR your burning more fat, its the ratio that changes, your just burning a higher amount of muscle compared to fat.
 
someone please tell me what HR is duh? and i am i doing ok with walking about 3 - 3.5 mph for 45 minutes?
 
may be the only time i'll admit to being wrong, but errtu has corrected me ... that is what i meant to say ... honest!
 
takes a real man to be able to admit when he's wrong :)
and nobody answered my question about the walking

wonderwomen: how often do you do it? you are obviously doing this on a treadmill ... i would suggest doing it outside and maybe look for some hilly areas ... you need to continually challenge yourself, so increasing the speed and maybe doing some jogging. I try to go for a walk 4-5/week for 45-60 minutes (mainly to clear my head of a days work), but I've also started running 2-3/week in the morning for 30 minutes.
 
what different does it make whether i burn "fat" or "protein"? i'm burning a calorie so i lose weight, right?
 
I walk on the tredmill at the gym for 40 min and I try to keep the tredmill up right like i am walking up a hill . I usually burn 220 cal. How do I know what is important to look for cal or heart rate of how long I am kind of confused. I want to loose weight and I have been just not sure what I should look at or how to find my target heart rate?
 
It's more important to look at your HR than the cals the machine says you burned. you need to get in your target HR zone and keep it there for 20 in order to burn a good number of cals and get your cardiovascular system going and gain endurance. going under your THR will probably not get you the results you want.
~heres the calculation to find your heart rate(this is what the AHA recomends)~

(220-your age)x 50%= your lower limit
(220-your age)x75%=your upper limit (really fit ppl can go to 85%)
you can measure your HR by taking your pulse for 10 or 15 sec.(the longer you take it the more accurate) then X"s it by 6 or 4 depending on how long you count for.(or get a HR monitor way easier ;) lol)
 
thanks for the info I am definatly going to try it!!!
