How can a treadmil calculate how many calories you've burned?!
Question: Is it accurate?
Answers: Is it accurate?
No they are not accurate. It makes a simple estimate based on distance and body mass. (Doesn't it make you enter your weight when you begin?) The amount of energy humans -- and all animals -- use during locomotion is pretty much proportional to distance and body mass regardless of gait (walking, trotting, or running).
Also, the makers of these devices inflate the readings.
Why? Since users in the gym will think they work better, they'll use those machines instead of some other brand of machine. When the gym then sees how popular those machines are they will buy more of them. Except that every manufacturer does this and all the machines inflate the readings.
And they can't stop, because if any one manufacturer stopped inflating readings, people would stop using those machines in favor of the ones that seem to work better.
So the manufacturers see no benefit and you still get an inaccurate reading.
(It's like a farmer who wants to make more money and begins using fertilizer to grow more crops. But then all the farmers start using fertilizer, and they all grow more crops, and prices fall. So they all grow a lot more crops, but no one ends up making any more money.)
It can't the tredmill calculator is a mathmatical calculation built into the firmware of the machine. It would still show you burning calories even if you had not been walking or running on the machine. No it is not accurate it is just a trend.
A crosstrainer has a better calculation because you have to apply a force to make it move as in a bike or rower..
This depends on how good yr treadmill is.
If it's a decent on that asks for your weight and age with a decent pulse pad then it may give you reasonably accurate numbers (70-80%) accuracy. A good treadmill will use your age and weight, combined with the speed and incline yr running at to come to the calorie count.
If you have a cheap treadmill that is more on the cheap side then u can't really trust it. On average if you 'jog' and not 'run' you'll usually burn between 300 calories within 35-45 mins. Of course, if you run faster you'll burn more calories.
Well that I my experience and I used to run daily.
