question/concern about skating...

i have been roller blading as exercise lately. there are two entries available for skating in the database. one is "rollerblading (in-line skating)" and the other is "skating (roller blading)". the first option burns (basically) twice as many calories than the second option. if i am roller blading, which one should i log in? i thought roller blades are technically in-line skates. i am confused and hoping that someone knows the correct difference.

Somebody has put in those calories by the looks of it but the calorie differences are deceiving.

This is an excerpt off the net re inline skating and roller blading - they are one and the same:

Rollerblading is a name used for this sport because of the large role that the Rollerblade Company played in making inline skating popular. Rollerblade, Inc. did not invent, design or manufacture the very first inline skates. But, the Rollerblade Company was so successful in marketing inline skates and equipment that the term “rollerblading” was and still is used when referring to inline skating sports. Inline skates are often called "rollerblades" regardless of which company actually built them. The name Rollerblade has become inline skating to most people, overshadowing other manufacturers and leaving out a lot of the history of roller and inline roller.

Inline skating or inline roller skating is the official name for “rollerblading” or “blading” sports and inline skates is the correct name for "rollerblades" manufactured by any other company. If you actually use Rollerblade brand skates, then you are really Rollerblading, otherwise, the correct description is inline skating.
