In-line Skating
Inline skating is a multi-disciplinary sport and can refer to a number of activities practiced using inline skates. Inline skates typically have two to five polyurethane wheels depending on the style of practice, 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 and maneuverability than traditional (or "quad") roller skates. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines. Inline skating is commonly referred to by the proprietary eponym ''rollerblading'', or just ''blading'', due to the popular brand of inline skates, Rollerblade. History An inline skate appeared in a Paris patent in 1819, but were overtaken in popularity by quad skates. The German branch of SKF developed and produced inline-skates in 1978 with wheels for hockey or for the street. The product was stopped after one year as the management did not want a consumer p ...

Amsterdam - Vondelpark - 1466
Amsterdam ( , , , lit. ''The Dam on the River Amstel'') is the capital and most populous city of the Netherlands, with The Hague being the seat of government. It has a population of 907,976 within the city proper, 1,558,755 in the urban area and 2,480,394 in the metropolitan area. Located in the Dutch province of North Holland, Amsterdam is colloquially referred to as the "Venice of the North", for its large number of canals, now designated a UNESCO World Heritage Site. Amsterdam was founded at the mouth of the Amstel River that was dammed to control flooding; the city's name derives from the Amstel dam. Originally a small fishing village in the late 12th century, Amsterdam became a major world port during the Dutch Golden Age of the 17th century, when the Netherlands was an economic powerhouse. Amsterdam is the leading center for finance and trade, as well as a hub of production of secular art. In the 19th and 20th centuries, the city expanded and many new neighborhoods ...

Aggressive Inline Skating Jerry 2012 Andrey Kolgan Ova
Aggression is overt or covert, often harmful, social interaction with the intention of inflicting damage or other harm upon another individual; although it can be channeled into creative and practical outlets for some. It may occur either reactively or without provocation. In humans, aggression can be caused by various triggers, from frustration due to blocked goals to feeling disrespected. Human aggression can be classified into direct and indirect aggression; whilst the former is characterized by physical or verbal behavior intended to cause harm to someone, the latter is characterized by behavior intended to harm the social relations of an individual or group. In definitions commonly used in the social sciences and behavioral sciences, aggression is an action or response by an individual that delivers something unpleasant to another person. Some definitions include that the individual must intend to harm another person. In an interdisciplinary perspective, aggression is regar ...

External Links
An internal link is a type of hyperlink on a web page to another page or resource, such as an image or document, on the same website or domain. Hyperlinks are considered either "external" or "internal" depending on their target or destination. Generally, a link to a page outside the same domain or website is considered external, whereas one that points at another section of the same web page or to another page of the same website or domain is considered internal. These definitions become clouded, however, when the same organization operates multiple domains functioning as a single web experience, e.g. when a secure commerce website is used for purchasing things displayed on a non-secure website. In these cases, links that are "external" by the above definition can conceivably be classified as "internal" for some purposes. Ultimately, an internal link points to a web page or resource in the same root directory. Similarly, seemingly "internal" links are in fact "external" for ...

Vert Ramp
A vert ramp is a form of half-pipe used in extreme sports such as vert skating, vert skateboarding and vert BMX. Vert ramps are so named because they transition from a horizontal plane (known as the flat-bottom) to a vertical section on top. The typical height of a vert ramp is to with anywhere from to of vertical on top. Vert skating ramps can be made with to of vertical while vert skateboarding ramps are made with of vertical in order for the skateboard to launch straight up into the air. This vertical section makes it easier for the riders to take off and 'catch air' on a vert ramp rather than on a half-pipe. This is because the vert at the top causes the rider to naturally go straight up into the air instead of forward and off the ramp (as is the tendency on half-pipes that don't go vertically upwards).

Gymnastics
Gymnastics is a type of sport that includes physical exercises requiring balance, strength, flexibility, agility, coordination, dedication and endurance. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, back, chest, and abdominal muscle groups. Gymnastics evolved from exercises used by the ancient Greeks that included skills for mounting and dismounting a horse, and from circus performance skills. The most common form of competitive gymnastics is artistic gymnastics (AG), which consists of, for women (WAG), the events floor, vault, uneven bars, and beam; and for men (MAG), the events floor, vault, rings, pommel horse, parallel bars, and horizontal bar. The governing body for gymnastics throughout the world is the Fédération Internationale de Gymnastique (FIG). Eight sports are governed by the FIG, which include gymnastics for all, men's and women's artistic gymnastics, rhythmic gymnastics, trampolining (including double mini-t ...

Roller Rink
A roller rink is a hard surface usually consisting of hardwood or concrete, used for roller skating or inline skating. This includes roller hockey, speed skating, roller derby, and individual recreational skating. Roller rinks can be located in an indoor or outdoor facility. Most skating center facilities range anywhere from under to more than . History Massachusetts businessman James Plimpton's 1863 invention of an improved roller skate led to a boom in popularity in the late 19th century, particularly in cities of the American East Coast. At first, people roller skated at home, but within twenty years businesses dedicated to the activity began to spring up. Plimpton himself is credited with opening the first roller skating rink in New York City. Patrons who enjoyed ice skating during the winter months participated in the similar activity, now year-round. Early roller rinks varied greatly in size and type, both indoor and outdoor. Many consisted of simple wooden platforms tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freestyle Slalom Skating
Freestyle slalom skating is a highly technical field of roller skating that involves performing tricks around a straight line of equally spaced cones. The most common spacing used in competitions is , with larger competitions also featuring lines spaced at and . Equipment Most freestyle slalomers use inline skates, although some use quad skates. Those who use inline skates tend to use a full rocker wheel configuration, however there are other variations of the rocker set-up which are used. Some skaters prefer to use a 'full hi-lo' rocker, which means the largest wheel is the second in from the back, with the smallest at the front. A common way to rocker your wheels is by putting larger wheels in the center and smaller wheels on each end. An example of this is having 80 mm wheels in the 2nd and 3rd position and 76 mm in the front and back. A short frame (230–245 mm) is used to give the skate the maximum possible maneuverability. Inline skates used for slalom have a very t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Skating
Road skating is the sport of skating (inline skating or quad roller skating) on roads, much like road cycling. It shares much with inline speed skating. Roadskaters often skate in tight packs, drafting each other and sharing the lead, which allows a pack to travel faster than an individual skater. The individual members of a pack use comparatively less energy than the lone skater traveling at the same speed. Even the lead skater in the pack enjoys an advantage from the drafting skaters behind. While gliding downhill, an inline skater in a tucked position can achieve speeds that exceed the speed of a tucked cyclist. This is due to lower wind resistance. The rolling resistance is similar for a cyclist and a skater — it is only when actively skating (i.e., in the skating stroke) that the skater incurs greater resistance. Skating is roughly 50% slower than cycling on flat ground. Skaters routinely achieve downhill speeds of 60 km/h (37 mph), similar to cyclists. Compa ...

Roller Skiing
Roller skiing is an off-snow equivalent to cross-country skiing. Roller skis have wheels on their ends and are used on a hard surface, to emulate .Bryhn, Rolf and Knut Are Tvedt (eds.): ''Kunnskapsforlagets idrettsleksikon''. (Norwegian Encyclopedia of Sports). Oslo: Kunnskapsforlaget, 1990. The skiing techniques used are very similar to techniques used in cross-country skiing on snow. First created as a summer training exercise, roller skiing grew into a competitive sport in its own right. Annual championships are held in various locations around the world. Most, if not all, national cross-country ski teams around the world roller ski during the off-season for specific physical training simulating winter skiing. In Norway, separate roller ski facilities have been constructed to allow exercise off public roads. History The first roller skis were built in the mid-1930s in Italy and North Europe. In the early 1950s, when cross-country skiing started to evolve to a serious competitio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
