Roller Skating Calories Burned Calculator

Calories burned roller skating is the energy your legs, hips and core use to push, glide, balance and stop on wheels. Your weight, how long you skate and how fast you go matter most. A slow lap at the rink and a fast trail skate are very different workloads.

What Roller Skating Calorie Estimates Measure

The result counts all the energy you use while skating, including what your body would burn at rest anyway, so it is a gross figure. It does not read your heart rate or track your distance.

The Formula

Calories (kcal) = MET x body weight (kg) x time (hours)

1 MET = about 1 kcal per kg of body weight per hour

Each MET is one unit of resting energy, so a 7 MET skate uses roughly seven times what your body needs sitting on a bench. Each skating value comes from the 2024 Adult Compendium of Physical Activities, a large research list of energy costs for adults aged 19 to 59¹.

How This Calculator Computes Your Result

Choose your age group, enter your weight in pounds or kilograms, pick a type of skating, and add your time. The calculator turns pounds into kilograms, finds the MET for your choice, and multiplies. Results are rounded to the nearest 5 kcal (or the nearest 1 kcal under 50), and the MET is shown to one decimal.

You also see calories per hour and per 30 minutes, and a table of all five options at your weight.

On in-line skates? Pick by speed. Enter your average moving speed from a watch or app. The tool picks the in-line row whose compendium speed is closest to yours, and it never blends two values. Below 9 mph you get the recreational row with a note that your burn may be lower, since the compendium lists no slower in-line speed¹. Quad skates have only the general row, with no speed attached¹.

Skating time only (optional). The default counts your whole session. If you spent time sitting, lacing skates or waiting out a couples skate, switch to this mode and enter only the minutes you were moving. Time spent off your skates is not counted, and the result says "active time only".

Skaters under 18 get no result, because youth values differ from adult ones. Skaters aged 60 and over get a note, because the Older Adult Compendium has no skating value².

What Your Result Means

Your result is the energy that skating session used, not a target to hit. This is what a 70 kg (154 lb) skater burns:

These figures assume you were skating for the whole time shown. A 90 kg (198 lb) skater burns about 630 kcal in an hour of general roller skating.

What Studies Measured on In-Line Skates

Researchers measured oxygen use in 19 adults skating at their own pace on a circular track³. The average was 9.1 METs³. A second study of 17 recreationally active adults found 9.4 METs at a self-chosen pace, which counts as vigorous exercise⁴. Both are higher than the compendium's 7.5 MET recreational row, but neither study summary gives a speed, so this calculator keeps the compendium values¹.

Fitness devices can miss in both directions. An armband activity monitor put the same skating at only 5.3 METs, about 42 percent below the measured value³. Heart rate went the other way: it ran about 174 beats per minute while skating, against about 156 for treadmill running at a similar oxygen use⁴. That means a heart rate based estimate can make skating look harder than it is⁴.

What Changes Your Burn on Roller Skates

Speed. On in-line skates, the compendium value climbs from 7.5 METs at about 9 mph to 15.5 at about 15 mph¹. At the same weight and time, fast skating at 13 mph burns about 64 percent more than recreational skating.

Rink sessions versus outdoor trails. A rink session mixes laps with couples skates, games, crowds, and time on the bench, so your moving time can be much shorter than your ticket time. Skating time only handles that. A trail skate is steadier and suits the speed picker. At 70 kg, in-line skating costs about 36 kcal per km at 9 mph and about 45 kcal per km at 15 mph¹. Going from 9 to 15 mph about doubles the burn per hour but adds only about a quarter per kilometer, because you cover the distance sooner.

Hills, wind and surface. Climbs, headwinds and rough pavement take more effort, and long downhills take less. The calculator does not adjust for these.

Roller Skating Compared With Ice Skating and Skateboarding

Calories for one continuous hour, using 2024 Adult Compendium values¹:

General roller skating and general ice skating share the same value in the compendium¹. Both sit above general skateboarding and a little above a general session on a stationary bike.

Protective Gear on Skates

A typical in-line skating injury was a beginner falling onto outstretched hands⁵. In a 1996 study of injured in-line skaters, wearing wrist guards and elbow pads cut the risk of injury to those body parts by over 80 percent⁵. These data come from in-line skaters in the 1990s.
