Calories burned sledding calculator

Sledding is rated at 5.3 METs in the Compendium of Physical Activities, meaning it costs about 5.3 times as much energy as sitting still.

Per hour at this intensity: 390 kcal/h
Net of what you would have burned resting: 158 kcal
Same energy: 815 kJ
Equivalent mass of pure fat: 21.6 g

Show the working

Body weight = 70
Time spent = 30
MET value = 5.3
kcal_per_min = 5.3 * 3.5 * 70 / 200 = 6.4925
Calories burned = 6.4925 * 30 = 194.775
Per hour at this intensity = 6.4925 * 60 = 389.55
Same energy = 194.775 * 4.184 = 814.939
Equivalent mass of pure fat = 194.775 / 9 = 21.6417
Net of what you would have burned resting = (5.3 - 1) * 3.5 * 70 / 200 * 30 = 158.025

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

kcal per minute = MET x 3.5 x body weight in kg / 200
The 3.5 is oxygen uptake in mL per kg per minute at one MET; the 200 converts millilitres of oxygen to kilocalories at 5 kcal per litre.
total = kcal per minute x minutes

MET values are population averages for an activity performed at a stated intensity. Fitness, technique and terrain all move the real figure.

The gross figure includes the calories you would have burned anyway just by being alive; the net figure subtracts them, and is the more honest number for a weight-loss calculation.

This is a population formula, not a diagnosis. Individual metabolism, body composition and medical history all move the real answer, so treat the number as a starting point and talk to a clinician about anything that matters.

Frequently asked

How many calories does sledding burn per hour?

At 5.3 METs, a 70 kg person burns about 390 kcal per hour. Heavier people burn proportionally more.

What is a MET?

A metabolic equivalent. One MET is the energy cost of sitting quietly, about 3.5 mL of oxygen per kilogram of body weight per minute, or roughly one kilocalorie per kilogram per hour.
