Vert skating
Is a term used to refer to riding inline skates on a Vert Ramp, a half pipe with some vertical in it usually between 6in to 24in. Vert skating is a form of gymnastics performed with skates. The purpose of vert skating is to ride higher than the coping (which is the metal pipe on top of the ramp) and perform spins or flips. It focuses on complicated aerial maneuvers, such as spins and flips. The intent of the skater is to build speed until they are of sufficient height above the edge of the ramp to perform various aerial acrobatics. In competitions skaters have limited time, often less than a minute, to impress the judges by landing numerous and difficult tricks. The sport was included in the first X-Games in 1995. Vert skating is used in a lot of competitions such as the X Games. Vert Ramps are also present in most skateparks of today.

Aggressive inline
In addition to speed, fitness, artistic, or recreational skating, some skaters prefer to skate aggressively. Aggressive skating is referred to by participants as rollerblading, blading, skating or rolling and includes a variety of grinds, airs, cess slides, toe/heel rolls and other advanced skating maneuvers. Types of aggressive skating include Park and Street.

Park skating refers to doing tricks within a skatepark. Street skating specifically refers to tricks performed on non-allocated obstacles (i.e. not skate parks).
