Cross-Country Skiing Burns More. Burning about 381 calories in 60 minutes of snowboarding provides a slower caloric burn than some other forms of winter exercise. A 160-pound person burns about 533 calories in an hour of slow-paced cross-country skiing and about 419 calories in 60 minutes of light ice skating. The caloric burn from light snowboarding is equivalent to that of light downhill skiing. Related Reading: How to Estimate the Total Calories You Burned While Running.
The Compendium of Physical Activitiesâa database that measures the energy expenditure of sports and activitiesâbills the two snowsports as equal when it comes to calorie burn. Downhill skiing and snowboarding both receive metabolic equivalent (MET) ratings of 4.3 for light effort and 5.3 for moderate effort, which means that a 150-pound person would burn between 293 and 361 calories an hour doing either.
