rollerskiing

904 kcal / hour Rollerskiing burns approximately 904 calories per hour for a 70 kg (154 lb) adult, and 452 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 646 to 1,550 kcal.

It carries a MET value of 12.3 in the 2024 Adult Compendium of Physical Activities, which lists 9 measured variations of this activity from MET 5.5 to 16.

Calories burned rollerskiing by body weight

Energy cost scales with the mass you move, so body weight changes the answer more than anything else.

Every official intensity of rollerskiing

The Compendium lists 9 separate rollerskiing entries, each with its own measured MET value — from 5.5 to 16. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.

Codes are 2024 Adult Compendium activity codes. A dash means the code could not be read unambiguously from the published table, so it is left blank rather than guessed — the MET value and description are unaffected.

What 904 calories an hour actually means

At MET 12.3, rollerskiing counts as very vigorous activity — it uses about 12.3 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 15 kcal per minute, or 904 kcal across a full hour.

Within winter activities, that ranks 2nd of 14 activities by energy cost, a little below biathlon training (MET 12.8) and above skating treadmill (MET 10.25).

Put differently: one hour of rollerskiing costs about the same energy as 185 minutes of ordinary walking.

On the food side, a medium banana (about 105 kcal) takes roughly 7 minutes of rollerskiing to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.

Questions

How many calories does rollerskiing burn per hour?

About 904 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 12.3. A 90 kg adult burns closer to 1,162 kcal in the same hour, because energy cost scales almost directly with body mass.

How many calories does 30 minutes of rollerskiing burn?

Roughly 452 kcal at 70 kg, 387 kcal at 60 kg and 646 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.

What is the MET value of rollerskiing?

12.3, taken as the median of the 9 rollerskiing entries in the 2024 Adult Compendium, which range from 5.5 to 16 depending on intensity. One MET is the energy you use sitting quietly, so MET 12.3 means 12.3 times that rate.

Is this an exact number of calories?

No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.

MET value from the 2024 Adult Compendium of Physical Activities (activity code 19305). Calories computed as MET × 3.5 × weight kg ÷ 200 per minute. General information only — not medical, fitness or nutrition advice. Calorie figures are population estimates and vary between individuals.
