Weight+Height and Nike Plus

muimuimui

Oh gosh;; I more or less just woke up..
Hello, back from prom. Good times. Up all night. Ate probably 3 days worth of calories in desserts.
But I also won a Nike Plus as one of the prizes they were giving away all night
So its a little motivation for getting back on track tomorrow, when I stop feeling like I'm going to drop dead in exhaustion.

Anyways, I have a question for the Nike Plus users. How accurate is it? Better than a treadmill? Can use any pair of shoes with the sensor as long as it stays on?

Also, I was wondering, when entering weight into Nike Plus (or anything that accounts for weight when doing cardio work outs) the weight correlates with how many calories you burn generally, yes?
ie. less weight = takes longer to burn off the calories
But I was wondering if height effects this weight to calorie burn ratio. Logically, it should, shouldn't it? If so, seeing as how Nikeplus doesn't ask for height, does this mean its going to be inaccurate? I've been wondering the same thing when entering my weight into the treadmills at the gym as well..

Weight is important because the more mass your body moves, the harder you are working and so the more calories you are burning. It doesn't matter how the weight is shaped only how much there is so that's why height isn't important.

But these are all formulas that are estimating and so they can all be inaccurate, especially if they aren't using your HR. Nike+ doesn't use HR but a lot of machines at the gym don't either even though they measure it!

My Nike+ and any treadmill I use tend to disagree. I don't know which one is more accurate. I used to have UnderArmour shoes and I had my sensor in a little pouch that tied to my laces. Now I have Nike shoes and I put the sensor in the hole for it. Supposedly that's more accurate but I've only done one run with the new shoes so I can't vouch for that. It's logical though.
