Inline Speed Skating
Roller speed skating is the roller sport of racing on inline skates. The sport may also be called ''inline racing'' or ''speed skating'' by participants. Although it primarily evolved from racing on traditional roller skates, the sport is similar enough to ice speed skating that many competitors are known to switch between inline and ice speed skating according to the season. Skate An inline speed skate is a specialized shoe version of the inline skate. The boot or shoe is close-fitting, without much padding and usually made of leather, Carbon fibers, carbon fiber, and/or fiberglass composite material, composites. For best performance, the boot must conform closely to the shape of the foot, so most inline speed skating boots are custom-fitted or else heat-moldable. Speed skating boots are low-cut and offer little ankle support, allowing the skater extra ankle movement. Skin blisters due to friction can be a problem, and common solutions include neoprene or silicone "ankle boote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ABEC Scale
The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. The ABEC scale is designed to provide bearing manufacturers dimensional specifications that meet the standards of precision bearings in a specified class. The scale is also used by manufacturers who produce equipment that require bearings must also know the dimensional tolerances to design parts that will accommodate a bearing. History It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). Tolerance classes There are five classes, which are named using the first five odd numbers: * 1 (widest tolerance) * 3 * 5 * 7 * 9 (tightest tolerance) The naming scheme is inverse with the tolerance, i.e. higher numbers mean lower tolerance. The higher ABEC classes (lower tolerance) provide better precision, efficiency, and the possibility of greater speed capabilities, but do not necessarily allow the components to spin faster. Bea ...

Patinodromes
A patinodrome is an arena for inline speed skating. They are oval tracks similar to velodromes used for track cycling, but have flat straights and shallow-banked or no banked curves. They are typically outdoors or under cover with open or partial walls. Patinodromes are common in Europe, but rare in North America. Design A patinodrome is generally about 160m to 250m in circumference and may be surfaced with asphalt, concrete or similar material. The curves may be banked.

Velodrome
A velodrome is an arena for track cycling. Modern velodromes feature steeply banked oval tracks, consisting of two 180-degree circular bends connected by two straights. The straights transition to the circular turn through a moderate easement curve. History The first velodromes were constructed during the late 1870s, the oldest of which is the Preston Park Velodrome, Brighton, United Kingdom, built in 1877 by the British Army. Some were purpose-built just for cycling, and others were built as part of facilities for other sports; many were built around athletics tracks or other grounds and any banking was shallow. Reflecting the then-lack of international standards, sizes varied and not all were built as ovals: for example, Preston Park is long and features four straights linked by banked curves, while the Portsmouth velodrome, in Portsmouth, has a single straight linked by one long curve. The oldest surviving regular velodrome two-straight oval tracks is from 1889, locate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Track Speed Skating
Short-track speed skating is a form of competitive ice skating, ice speed skating. In competitions, multiple skaters (typically between four and six) skate on an oval ice track with a length of . The rink itself is long by wide, which is the same size as an Olympic-sized figure skating rink and an international-sized ice hockey rink. Related sports include long-track speed skating and inline speed skating. History Short-track skating developed from speed skating events that were held with mass starts. This form of speed skating was mainly practised in the United States and Canada, as opposed to the international form (derived from Europe), where athletes skated in pairs. At the 1932 Winter Olympics, speed skating events were conducted in the mass start form. Competitions in North America tended to be held indoors, for example in Madison Square Garden, New York, and therefore on shorter tracks than was usual for outdoor skating. In 1967, the International Skating Union (ISU) ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USARS
USA Roller Sports (USARS), formerly the United States Amateur Confederation of Roller Skating, is the national governing body of competitive roller sports (inline skating and roller skating) in the United States. It is recognized by the World Skate and the United States Olympic Committee. USA Roller Sports has sponsored amateur roller skating competitions at the regional and national level since 1937 in figure skating, speed skating and roller hockey; and since 2011 in roller derby. USARS has been the United States representative for the International Federation of Roller Sports (FIRS) since 1972, when it obtained this designation after the merger of two predecessor roller skating federations (the Roller Skating Rink Operators' Association or RSROA established in 1937, and the U. S. Amateur Roller Skating Association, or USARSA). The organization exercises jurisdiction over matters pertaining to the participation of United States roller skaters in international competition, includ ...

Peloton
In a road Cycle sport, bicycle race, the peloton (, originally meaning ) is the main group or pack of riders. Riders in a group save energy by riding close (drafting (racing), drafting or slipstreaming) to (particularly behind) other riders. The reduction in drag (physics), drag is dramatic; riding in the middle of a well-developed group, drag can be reduced by as much as 95%. Exploitation of this potential energy saving leads to complex cooperative and competitive interactions between riders and teams in race tactics. The term is also used to refer to the community of professional cyclists in general. Definition More formally, a peloton is defined as "two or more cyclists riding in sufficiently close proximity to be located either in one of two basic positions: (1) behind cyclists in zones of reduced air pressure, referred to as ‘drafting’, or (2) in non-drafting positions where air pressure is highest. Cyclists in drafting zones expend less energy than in front positions." A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drafting (aerodynamics)
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle. Drafting in sport Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. Some forms of triathlon allow drafting. Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. In a competition pool a swimmer may hug the lane line that separates them from the swimmer they are abaft of thereby t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bicycle Racing
Road bicycle racing is the cycle sport discipline of road cycling, held primarily on Road surface, paved roads. Road racing is the most popular professional form of bicycle racing, in terms of numbers of competitors, events and spectators. The two most common competition formats are mass start events, where riders start simultaneously (though sometimes with a Handicapping, handicap) and race to a set finish point; and time trials, where individual time trial, individual riders or team time trial, teams race a course alone against the clock. Stage races or "tours" take multiple days, and consist of several mass-start or time-trial stages ridden consecutively. Professional racing originated in Western Europe, centred in France, Spain, Italy and the Low Countries. Since the mid-1980s, the sport has diversified, with races held at the professional, semi-professional and amateur levels, worldwide. The sport is governed by the (UCI). As well as the UCI's annual UCI Road World Champio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hockey Stop
A hockey stop is a specific and primary way of stopping on ice skates while playing ice hockey. The hockey stop allows the skater to change directions quickly, keeping up with play. It takes practice to effectively stop facing both ways, most skaters are stronger stopping one direction over another (i.e. stop right as opposed to left). To hockey stop, once the skater has assumed some speed, he/she, while always in the hockey position, will rapidly pivot their hips 90 degrees. The pivot turns the skates, and the skater is using both skates to stop. The outside skate uses the inside edge to stop while the inside skate uses the outside edge. Edges on both skates are used to stop. Sometimes skaters like to use just the inside edge of their outside skate. While they are still stopping, it takes longer and more energy as well as wears out the edges faster. As with the hockey position, the legs in a hockey stop will be about shoulder width apart, and shoulders parallel to the ice for b ...

Chad Hedrick
Chad Hedrick (born April 17, 1977) is an American inline speed skater and ice speed skater. He was born in Spring, Texas. Hedrick revolutionized the inline speed skating world with his unique technique, called the double push, or DP. During his career he won 93 national championships and 50 world championships, as well as having a brand of inline skating wheels named after him. Speed skating After winning his 50th World Championship, in Ostend, Belgium, in 2002, he switched to ice speed skating after watching, on a television in a Las Vegas casino in 2002, fellow inline skater Derek Parra win a medal at the Salt Lake City Winter Olympics. In February 2004, a year and a half after he made his switch, Hedrick won the 2004 World Allround Speed Skating Championships, knocking more than a point off the world record points, reducing it to 150.478. On March 12, 2004, Hedrick won the gold medal in the 5,000 meters during the 2004 World Single Distance Championships, which were held S ...

Double Push
Double push is an inline speed skating technique. Its major advantage over the previously practised "classic" technique is that it allows the skater to do useful work during the part of the stride that was "wasted", and therefore to go faster. Opinions differ on its usefulness for non-elite skaters as it requires much practice before a skater is faster using doublepush than without. History It is uncertain who first invented the doublepush. Chad Hedrick is generally acknowledged as having brought it to the public eye. Prior to Chad's arrival on the scene circa 1992, inline speed skaters used the classic speed skating technique derived from ice speed skating. Hedrick's alternative approach rapidly proved itself to be faster and was soon adopted by many elite skaters. Technique Wheels used in speed skating are usually round or elliptical in profile, and do not literally have edges. The terminology is carried over from ice skate Ice skates are metal blades attached underfoot a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
