Context paragraphs:
Nordic cross skating: Nordic cross skating is also called Nordic inline skating or Off-road skating or Cross-country skating or Nordic blading.  This sport activity (similar to Roller skiing) combines snow Cross-country skiing and Inline skating.  Typically uses specialized inline skates with two big all-terrain wheels (4-6 inch diameter, typically pneumatic) and special poles that the skater pumps like ski poles to make the skates go faster and provides a good workout for the majority of the major muscle groups, including upper body.  Nordic skaters use a technique similar to the technique that cross-country skiers and inline skaters use.  Nordic cross skating popularity is growing because of the range of fitness benefits.

Roller Derby (brand): Roller Derby Skate Corp is an American manufacturer and distributor of sporting goods, specializing in quad skates, inline skates, ice hockey skates, skateboards, skating accessories, and recently, through its acquisition of 360 Inc., sporting goods for water sports including body boards, surfboards and swim products.  Roller Derby sells products under the brands Roller Derby, California Advanced Sports, Pacer, Labeda and 360 Inc.  It is the second-largest supplier of inline skates to the U.S. market.  They have just introduced a Labeda skate that is designed for roller derby.

Inline skating: Inline skating is a multi-disciplinary sport practiced widely internationally.  Inline skates typically have 2 to 5 polyurethane wheels, arranged in a single line by a metal or plastic frame on the underside of a boot.  The in-line design allows for greater speed than roller skates and better maneuverability.  Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines.

Roller hockey: Roller hockey is a form of hockey played on a dry surface using wheeled skates.  Most professional-inline hockey games take place on an indoor or outdoor sport court (a type of plastic interlinking tiles used to create a skating surface).  Otherwise, any dry surface can be used to host a game, typically a roller rink, macadam, or cement.  The term "Roller Hockey" is often used interchangeably to refer to two variant forms chiefly differentiated by the type of skates and sticks used.  There is traditional "Roller hockey" (Quad hockey, Rink hockey), played with quad skates, and "Inline hockey", played with inline skates.  Combined, roller hockey is played in nearly 60 countries worldwide.  A minor variant of roller hockey is called skater hockey, played on both quad and inline skates.

Inline skates: Inline skates are a type of roller skate used for inline skating.  Unlike quad skates, which have two front and two rear wheels, inline skates typically have two to five wheels arranged in a single line.  Some, especially those for recreation, have a rubber "stop" or "brake" block attached to the rear of one or occasionally both of the skates so that the skater can slow down or stop by leaning back on the foot with the brake skate.

Rowbike: A rowbike is an example of a rowing cycle, hybrid fitness/transport machine that combines a bicycle, and a rowing machine.  "Rowbike" is a trademark of the Rowbike company.  The Rowbike was invented by Scott Olson, the creator of Rollerblade inline skates.  "Rowling" is a combination of rowing and rolling and is sometimes used in place of rowing when describing a rowbike.

Inline hockey in the United Kingdom: Inline hockey and skater hockey are team sports, similar to ice hockey.  In the UK, there are two associations that govern inline hockey.  The British Inline Puck Hockey Association (BIPHA) govern the sport with rules using a Puck.  The British inline Skater Hockey Association (BiSHA) is different from BIPHA as BiSHA uses a Ball, Inline skates and roller skates and is played to full-contact rules.  GBinline, Inline UK and BRHA, are minor association within the country.

Roller skating: Roller skating is the traveling on surfaces with roller skates.  It is a form of recreational activity as well as a sport, and can also be a form of transportation.  Skates generally come in three basic varieties: quad roller skates, inline skates or blades and tri-skates, though some have experimented with a single-wheeled "quintessence skate" or other variations on the basic skate design.  In America, this hobby was most popular, first between 1935 and the early 1960s and then in the 1970s, when polyurethane wheels were created and "Disco" oriented roller rinks were the rage and then again in the 1990s when in-line outdoor roller skating, thanks to the improvement made to inline roller skates in 1981 by Scott Olson, took hold.

Rollerblade: Rollerblade is a brand of inline skates owned by Nordica, part of the Tecnica Group of Giavera del Montello, Treviso, Italy.

Inline speed skating: Inline speed skating is the roller sport of racing on inline skates, or as they're commonly called, rollerblades.  It is often called "inline racing" by participants.  Although it primarily evolved from racing on traditional roller skates, the sport is similar enough to ice speed skating that many competitors are now known to switch between inline and ice speed skating according to the season.
