HO CHI MINH CITY Adidas Tubular Defiant Mujer Blancas España , Jan. 19 (Xinhua) -- Among street sports that attract many young people in Vietnam, Parkour is seen as a newcomer, yet its popularity has already expanded rapidly, especially in big cities such as its capital Hanoi and southern Ho Chi Minh (HCM) City.
Parkour is a blend of sports, art, kung-fu and performance dance, which can be described as moving over, under, around Adidas Tubular X Blancas Hombre España , and through obstacles that exits naturally in the urban environment, elegantly, and with flair and efficiency.
A form of free running, Parkour is a holistic training discipline using flexible movements that have been developed from training on military obstacle courses.
Practitioners train how to move from one place to another in the most efficient way possible by using their body and the surroundings for propulsion, with the focus being on maintaining as much momentum as possible while still remaining safe.
First appearing in Vietnam in 2006, young Vietnamese players learned the sport through clips on the Internet. To date, there are many Parkour clubs across the country, but mostly in Hanoi and HCM City.
In Hanoi, groups of Parkour practitioners normally gather in the Thong Nhat Park Adidas Tubular Defiant W Mujer Rojas España , or on the campus of the University of Science and Technology, while in HCM City they practice at Le Thi Rieng Park in District 10.
According to Pham Viet Trung, one of the leaders of "Joker," a famous Parkour club in Hanoi, which boasts about 50 members, and one of the country's pioneering Parkour practitioners, Asians and Vietnamese people in particular, did not know much about the sport until recently.
"Actually Vietnamese Parkour players have earned a certain reputation among their counterparts in other countries and Parkour powers, such as France and Britain Adidas AlphaBounce Beyond Hombre Negras Blancas España ," Trung told Xinhua, adding that the sport focuses more on flexibility, agility and creativity, rather than physical strength.
Trung said Parkour players can be of different ages, but mostly young men, who should each have a good pair of shoes and a comfortable outfit. They can practice the sport alone or with friends, and perform such moves as speed vaults, obstacle running, climbing Adidas Swift Run España , swinging, vaulting, jumping, rolling, and quadrupedal movements.
While Parkour's young lovers said it helps them train to overcome fears and shyness, as well as keeping them fit and healthy, their parents sometimes see the sport dangerous and risky.
Nguyen Khanh, 65, a retired worker in Hanoi Adidas Deerupt Runner España , said he felt worried about his son's Parkour hobby.
"My son has practiced the sport for more than two years mainly during the weekends with his friends in the park near my house. It 's true that he has become stronger physically, but he also faced several injuries, but luckily enough they were not all so serious, " the father said, adding that he only feels at ease when his 16- year-old son returns home safely.
Actually, one of the sport's utmost requirements is to ensure the player's safety, as it was originally designed to help soldiers steer clear from danger.
Le Son, a 20-year-old experienced Parkour practitioner, said that the local Parkour community wants to develop the sport into a street art rather than a risky sport.
"Parkour needs greater investment Adidas Hender Scheme España , better organization and coaching, along with more solid theoretical background, if we want to expand it further in society," Son told Xinhua, adding that most Parkour players train by copying clips from the Internet, or they share personal experience with one another, and collectively try to perfect moves that the individual or group has been struggling with.
Launched in France, primarily by Raymond Belle, David Belle Adidas Spezial España , and Sbastien Foucan during the late 1980s, Parkour became popular in the late 1990s and 2000s through movies, documentaries and advertisements featuring those practitioners.

The liquid crystal display (LCD monitor or LCD) is the main component of flat panel displays. It is mainly used since the late 1990s black and white and in color since the beginning of 2000 in mobile phones, personal computers, televisions, on-board computers for aircraft and cars. Its main advantage is its low power consumption.
It uses the polarization of light polarizing filters and the birefringence of some nematic liquid Crystal phase, which can be varied depending on the orientation of the electric field. From the optical point of view, the LCD is a passive device: it does not emit light Adidas Futurecraft 4D España , transparency varies, and it must be informed.
First available in monochrome and small, it is used in calculators and watches because of its low power consumption and allows current to display in color in sizes exceeding one meter diagonal. He replaced the cathode ray tube in most applications, except in high definition when the color palette should be accurate and true, and in harsh environments (as in temperatures below 5 ° C).
Depending on the relative transparency of the liquid crystal devices: 15% for monochrome displays, and less than 5% for color displays, due to the interposition of the mask color, multiple lighting modes have been adapted:
Light transmission: the screen works with a backlight (TV, computer monitor Adidas Prophere España , camera and video camera) or by a discharge lamp cold cathode, light is divided by two orthogonal prisms networks.
The main features are:
Brightness of the screen is not sufficient in sunlight.The power consumption of the light source is two to three times less than a tube cathode1, 10 to 40 W depending on the lighting, for a screen 48 cm (19 inches), and less than 1 W standby.
The lifetime of lamps: 2.4 times more than a CRT, with 60 000 hours1 or 33 years if the screen is on five hours a day.OLED (Organic light-emitting diode) include organic light emitting diodes.
