not burning enough calories?

Posts: 3
running on the treadmill for ~45 minutes, i burn about 430 calories. when i go to log it and i put in 45 minutes, it fills in calories for 594! am i paying too close attention to the calories since they're usually off on the machine anyways? or should i be burning a lot more than i am?

I just heard on the radio today that these machines generally over-estimate the number of calories burned. You need to factor in height, weight, m/f, etc.0

look into getting a heart rate monitor. It'll do you wonders. The exercise machines are off...especially the ones you dont enter your height and weight. Good heart rate monitors to look into are Polar F6 or a Pro-form Precision XT.... i got mine off of Buy.com...it was only 30ish bucks...you can also find cheap finds on ebay and on woot.com
This is the one I have:

You definitely need a HRM. Even then, when you enter in "running on treadmill", you may need to adjust the calories every time, based on the length of time entered.
Good luck!:flowerforyou:0 -
I ordered that same heart rate monitor after seeing it on here! I should get it in the next day or two!0

Try this to check:
1. multiply speed (mph) x 26.8 to determine meters/min.
Ex: 6.0 mph x 26.8 = 160.8 m/min
2. multiply m/min x 0.2
3. add 3.5 to the total from #2
4. Divide total from #3 by 3.5--this gives you your intensity in METS
5. Multiply METS x your weight (in kg) to determine Calories/hour
6. Multiply Calories/hour by .75 to get Calories burned in 45 minutes.
Example: 70 Kg (154lb) runner at 6.0 mph
1. Meters/min= 160.8
2. 160.8 x 0.2 = 32.16
3. 32.16 + 3.5 = 35.66
4. METS = 10.2 (35.66/3.5)
5. Calories/hour = 714
6. Calories/45 min = 536
This is only accurate for running at speeds greater than 5.0 mph, on the level. For a treadmill it probably overestimates by 5% or so because of lack of wind resistance.
You can use the same formula for walking at speeds less than 4.2 mph--the difference is: In step 2, multiply meters/min by 0.1 instead of 0.2.0 -
It all depends on you and the machine. After getting an HRM I found I was actually burning double what the machines were telling me.0

I think what you are referring to is the difference between the machine and what MFP says? Are you inputting the speed into MFP? In general, I would use the smaller of the two numbers or take the average. Even though MFP will calculate the calories using the time you enter you can override that and enter in the calories yourself. Most machines are off but it depends on your particular case. At my gym you don't enter in your weight on the treadmills so it under estimates my calories since I am heavier than the average girl :happy:
I also agree that a heart rate monior would be useful if you can afford one.0
