Parkour is a sport with the aim of moving from one point to another as smoothly, efficiently and quickly as possible using chiefly the abilities of the human body. It’s more similar to martial arts (武术) than to a sport. Parkour focuses on how any obstacle is dealt with, whether the obstacle is either physical or mental.
Inspiration for parkour came from the “Natural Method of Physical Culture” developed by Georges Hebert in the early twentieth century. French soldiers in Vietnam were inspired by Heber’s work and created what is now known as parcours du batant (障碍训练课程). David Belle, who was introduced to this method by his father Raymond Belle, a Vietnamese soldier who had practiced it, had taken part in activities such as martial arts and gymnastics, and sought to apply his athletic skill in a manner that would have practical use in life.
After moving to Lisses, David Belle continued his journey with others. “From then on we developed,” says Sebastien Foucan, who helped to spread parkour, “and really the whole town was there for us; there for parkour.”
Over the years as devoted practitioners (实践者) improved their skills, their moves continued to grow in scale, so that building-to-building jumps and drops of over a storey(楼层) became mon in media description, causing much misunderstanding on the nature of parkour.”
Although many practitioners say parkour isn’t an extreme sport, it does carry risk with it. The practice of running, jumping, and leaping from a variety of urban structures (roof tops, staircases, raised surfaces, walls, etc.) and landing on concrete, of course, carries the potential for injury. Some of the most mon injuries include sprained (扭伤的) ankles and injuries to the knees.
According to one practitioner, “One of the biggest differences between parkour and other so-called ‘extreme’ sports is that it is not concerned only with physical skills, but also with one’s mental and spiritual pleasure.”
