Well, there are websites with charts that'll give approximate calorie usage depending on activity.
Do a net search for "calorie" + the activity of choice and you'll probably find something useful. But a more accurate way is to get a heart rate monitor with a calorie counter feature.
To calculate the amount of heat given off when burning a piece of candy, you can use the energy content of the candy. Given that the candy contains either 5 calories or 5000 calories, the heat released would be either 5 calories or 5000 calories. This heat would be released in the form of thermal energy as the candy is burned down to carbon dioxide and water.
Most calories a burned off by sweating
Calories burned by surfing will depend on the sex of the person and how much they weigh. For instance, a male that is 210 pounds and surfs for 30 minutes will burn 306 calories.
One pound = 3500 calories. Decreasing calories by 500 per day for a week = 3500 calories lost or 1 pound.
Food is burned to see how much energy is given off. The food is places in a sealed container and burned to measure the rise in water temperature. The amount of energy given off is the amount of calories in the food.
1,800 extra calories consumed (without being burned off) is equal to 1/2 pound of weight on the body.
The absolute best walking calculator that shows calories burned is the Amour 39 chest strap from Under Armour. It takes an accurate heart rate and monitors how many calories you've burned exactly regardless of what activity your doing. The $150 price tag may be a turn off though.
There are 4.184 joules in a calorie, therefore to burn off 464.. 464/4.184 = 110.899 calories.
My best guess is that it's not much more different than walking in deep mud, or wearing really heavy work boots. The calories burned might be hard to measure, but it will definitely help work your leg muscles, which of course burns some calories. I'd just add maybe 20% to normal walking calories burned. I may be way off, though...
a measure of the thermal energy that food will give off as it is burned the unit equal to 1000 calories also referred to as a calorie
Yes. A calorie burned is the same no matter how you burn it off.
That's almost impossible to answer without sufficient information. I can tell you how much calories you shouldn't be eating. I have read on a website that eating 3500 calories less per week will take off one pound. So that means eating 500 less calories each day of the week, which is very easy to do once you learn what foods you should be eating and what foods aren't so nice. It is also a good idea to burn off 250 calories with exercise everyday and get rid of the other 250 daily by eating right.
