Roller skates are boots with wheels mounted to the bottom, allowing the user to travel on hard surfaces similarly to an ice skater on ice. The first roller skate was an inline skate design, effectively an ice skate with a line of wheels replacing the blade. In modern usage, the term typically refers to skates with two pairs of wheels on shared axles like those of skateboards (early versions of which were made using roller skate parts). Skates with this configuration are also known as "quad skates" or "quads" and, like skateboards, steer by tilting the skate to one side, which causes the axles to turn inward.
While the first reported use of wheeled skates was on a London stage in 1743, the first patented "roller skate" was introduced in 1760 by Belgian inventor John Joseph Merlin. [1] They were hard to steer and stopping was difficult due to the fact that they did not have any type of braking mechanism and as such they failed to gain popularity. Merlin demonstrated his invention during a party in the city of Huy, during which he skated while playing the violin. [2]
In the 1840s, Meyerbeer's opera Le prophète featured a scene in which performers used roller-skates to simulate ice-skating on a frozen lake set on stage. This exposure had an impact on audiences and led to the rise of roller skating as a new and popular activity throughout the Continent. As ice skaters subsequently developed the art of figure skating, roller skaters wanted the ability to turn in their skates in a similar fashion. [3]
In 1863, James Plimpton from Massachusetts invented the "rocking" skate and used a four-wheel configuration for stability, and independent axles that turned by pressing to one side of the skate or the other when the skater wants to create an edge. This was a vast improvement on the Merlin design, one that was easier to use and drove the huge popularity of roller skating, dubbed "rinkomania" in the 1860s and 1870s, [4] which spread to Europe and around the world, and continued through the 1930s. The Plimpton skate is still used today.
Eventually, roller skating evolved from just a pastime to a competitive sport; speed skating, racing on skates, and inline figure skating, very similar to what can be seen in the Olympics on ice. In the mid 1990s roller hockey, played with a ball rather than a puck, became so popular that it even made an appearance in the Olympics in 1992. The National Sporting Goods Association statistics showed, from a 1999 study, that 2.5 million people played roller hockey. Roller skating was considered for the 2012 Summer Olympics [5] but has never become an Olympic event. Other roller skating sports include jam skating and roller derby.
Roller skating popularity began during the late 1950s and 1960s at rock 'n' roll teen dance halls, but exploded and took off in the 1970s and 1980s due to the introduction of large rubberized polymer wheels such as Krypto-Pro, to replace metal wheels, becoming popular and an iconic thing of that time. In the early 1990s it would begin to diminish in popularity. Sales of roller skates increased during the COVID-19 pandemic as people sought safe outdoor activities. [6]
Roller skating saw a revival in the late 2010s and early 2020s, spurred on by a number of viral videos on the popular video-sharing app TikTok and also a revival of 1970s and 1980s pop culture from film and TV nostalgia. Many popular brands sold out to the point of back-order, with many people taking up the hobby during COVID-19 quarantines across the globe. [7]
A roller skate has two main parts: the boot and the plate, which is the part that holds the wheels and provides the ability to steer. There are two main categories of roller skate boots: a high-top boot with a raised heel similar to an ice figure skating boot, and a flat-soled boot cut at or below the ankle. The plate is bolted to the boot, typically by drilling holes through the sole of the boot to match existing holes in the plates and placing bolts with low-profile heads inside the boots with nuts on the outside facing the floor. For boots with a raised heel, screws can be driven into the heel directly. Roller skate plates are composed of several parts: the base structural component is also called the plate, and the trucks, which are the main steering components, are attached to it in a way that allows the trucks to steer when the plate is tilted. Almost all roller skate plates achieve this by sandwiching each truck between a pair of flexible cylindrical "cushions" or bushings so that it can tilt. The stack is held together by a "kingpin" that passes through the center of the stack and is used to adjust the compression applied to the cushions. The "traditional" kingpin is a bolt that threads into the plate and is secured by a jam nut against the plate. Most modern plates use a "flipped" kingpin instead, which is a threaded stud attached to the plate and allows preload adjustments using a locking nut. To prevent the truck from rotating around the kingpin, an additional protrusion from the truck called a "pivot pin" sits in a cup on the plate.
The Roller Skating Rink Operators Association was developed in the U.S. in 1937. It is currently named the Roller Skating Association. The association promotes roller skating and offers classes to the public, aiming to educate the population about roller skating. Its current president is Bobby Pender and the associations headquarters are located in Indianapolis.
The Roller Skating Association's web page offers some health benefits of roller skating. Some of the benefits they list include: [8]
Speed skating is a competitive form of ice skating in which the competitors race each other in travelling a certain distance on skates. Types of speed skating are long-track speed skating, short-track speed skating, and marathon speed skating. In the Olympic Games, long-track speed skating is usually referred to as just "speed skating", while short-track speed skating is known as "short track". The International Skating Union (ISU), the governing body of competitive ice sports, refers to long track as "speed skating" and short track as "short track skating". Long track speed skating takes place on a 400m ice track, while short track takes place on a 111m track.
Ice skates are metal blades attached underfoot and used to propel the bearer across a sheet of ice while ice skating.
Inline skates are boots with wheels arranged in a single line from front to back, allowing a skater to roll along on these wheels. Inline skates are technically a type of roller skate, but most people associate the term roller skates with quad skates, another type of roller skate with a two-by-two wheel arrangement similar to a car. Quad skates were popularized in the late 19th and early 20th centuries. Inline skates became prominent in the late 1980s with the rise of Rollerblade, Inc., and peaked in the late 1990s. The registered trademark Rollerblade has since become a generic trademark due to its popularity. To this day, "rollerblades" continues to be used in everyday language to refer to inline skates.
Roller skating is the act of travelling on surfaces with roller skates. It is a recreational activity, a sport, and a form of transportation. Roller rinks and skate parks are built for roller skating, though it also takes place on streets, sidewalks, and bike paths.
Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear. It is used in the creation of steering and suspension. If the top of the wheel is further out than the bottom, it is called positive camber; if the bottom of the wheel is further out than the top, it is called negative camber.
Inline 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.
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 roller skates. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines.
A longboard is a type of skateboard typified by longer decks and wheelbases, larger-diameter and softer (lower-durometer) wheels, and often lower riding height compared to street skateboards, though there is wide variation in the geometry and construction of longboards. Among the earliest types of skateboards, longboards were inspired by surfing, with early longboards drawing from the design of surfboards, resembling and mimicking the motion of riding a surfboard, but adapted to riding on streets in a practice known as sidewalk surfing.
Longboarding is a variation of skateboarding typified by the use of longer boards ("decks") with longer wheelbases and softer wheels. While longboards vary widely in shape and size, compared to street skateboards longboards are designed to be more stable at speed and to have more traction due to larger wheel sizes and softer wheel durometers. While standard street skateboards may typically be between 28 and 34 inches long, longboards can range anywhere from 32 to 50 inches in length. Ride characteristics of longboards generally differ from that of street skateboards due to the use of specialized longboard trucks that have different properties than those typically used with skateboards; while street skateboards use "traditional kingpin" (TKP) trucks that are optimized for tight turning radii, ollie and flip tricks, slides, grinds, and transition skating, longboards are typically paired with "reverse kingpin" (RKP) trucks that are designed for increased stability at higher speeds, more "surfy" carving characteristics, and/or greater ride comfort for commuting over longer distances.
Mountainboarding (MTB), also known as dirtboarding, off-road boarding, and All-Terrain Boarding (ATB), is a well-established, but little-known action sport derived from snowboarding. The sport was initially pioneered by James Stanley during a visit to the Matterhorn in the 1990s, where snow was not available. A mountainboard is made up of components including a deck, bindings, four wheels with pneumatic tires, and two steering mechanisms known as trucks. Mountainboarders, also known as riders, ride specifically designed boardercross tracks, slopestyle parks, grass hills, woodlands, gravel tracks, streets, skateparks, ski resorts, BMX courses, and mountain bike trails. It is this ability to ride such a variety of terrain that makes mountainboarding unique from other board sports.
Inline hockey or roller hockey is a variant of hockey played on a hard, smooth surface, with players using inline skates to move and ice hockey sticks to shoot a hard, plastic puck into their opponent's goal to score points. The sport is a very fast-paced and free-flowing game and is considered a contact sport, but body checking is prohibited. There are five players including the goalkeeper from each team on the rink at a time, while teams normally consist of 16 players. There are professional leagues, one of which is the National Roller Hockey League (NRHL). While it is not a contact sport, there are exceptions, i.e. the NRHL involves fighting.
Artistic roller skating is a competitive sport similar to figure skating but where competitors wear roller skates instead of ice skates. Within artistic roller skating, there are several disciplines:
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 cross-country skiing. The skiing techniques used are very similar to techniques used in cross-country skiing on snow.
A skateboard is a type of sports equipment used for skateboarding. It is usually made of a specially designed 7–8-ply maple plywood deck and has polyurethane wheels attached to the underside by a pair of skateboarding trucks.
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 14,000 square feet (1,300 m2) to more than 21,000 square feet (2,000 m2).
Aggressive inline skating is a sub-discipline of inline skating in the action sports canon. Aggressive inline skates are specially modified to accommodate grinds and jumps. Aggressive skating can take place on found street obstacles or at skate parks.
Street skateboarding is a skateboarding discipline which focuses on flat-ground tricks, grinds, slides and aerials within urban environments, and public spaces. Street skateboarders meet, skate, and hang out in and around urban areas referred to as "spots," which are commonly streets, plazas or industrial areas. To add variety and complexity to street skateboarding, obstacles such as handrails, stairs, walls, flower beds, bins, park benches, picnic tables, and other street furniture may be traversed as single tricks or as part of a series of consecutive tricks called a "line."
Human-powered land vehicles are land vehicles propelled over ground by human power, The main ways to support the weight of a human-powered land vehicle and its contents above the ground are rolling contact; sliding contact; intermittent contact; no contact at all as with anything carried; or some combination of the above. The main methods of using human power to propel a land vehicle are some kind of drivetrain; pushing laterally against the ground with a wheel, skate, or ski that simultaneously moves forward; by pushing against the ground directly with an appendage opposite to the direction of travel; or by propeller. Human-powered land vehicles can be propelled by persons riding in the vehicle or by persons walking or running and not supported by the vehicle.
