Parkour (sometimes abbreviated to PK) or “l’art du déplacement” is an activity with the aim of moving from one point to another as efficiently and quickly as possible, using the innate abilities of the human body. It is meant to help one overcome obstacles, which can be anything in the surrounding environment—from branches and rocks to rails and concrete walls—and can be practiced in both rural and urban areas. Parkour practitioners are referred to as traceurs, or traceuses for females.
Free running (sometimes abbreviated to FR) combines all of the movements of parkour with movements from tricking. This discipline uses the human body to create art. Free running can be done in the urban and rural environment. Practitioners are referred to as free runners for both genders.
Tricking is acrobatic movement done purely for aesthetic purposes. It utilizes movements from many different sources such as freerunning, gymnastics, breakdancing, and martial arts. Practitioners are referred to as trickers for both genders.
