Human-powered Transport
Human-powered transport is the transport of passenger, person(s) and/or goods (freight) using human power, human muscle power. Unlike animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and human swimming, swimming, as well as small vehicles such as litter (vehicle), litters, pulled rickshaw, rickshaws, wheelchairs and wheelbarrows. Modern technology has allowed mechanical advantage devices and machines to enhance human-power. Although motor vehicle, motorization has increased speed and load capacity, many forms of human-powered transport remain popular for reasons of cost, convenience, leisure, physical exercise and environmentalism. Human-powered transport is sometimes the only type available, especially in less developed countries, underdeveloped or inaccessible regions.

Sherpa Carrying Woods
SHERPA (Securing a Hybrid Environment for Research Preservation and Access) is an organisation originally set up in 2002 to run and manage the SHERPA Project. History SHERPA began as an endeavour to support the establishment of a number of open access institutional repositories based in UK universities. SHERPA, the organisation, is sometimes erroneously referred to as the SHERPA Project. SHERPA was founded in 2002 by Stephen Pinfield, who continued as its director until 2012. Throughout its life, SHERPA has been managed by Bill Hubbard, first as its manager then as director from 2012 onwards. As well as a staff team based at Jisc (formerly the University of Nottingham), 33 research institutions and organisations comprise the SHERPA Partnership. The makeup of this partnership includes many, if not all, of the most research active institutions in the UK and provides practitioner-led experience to the project team.

Motor Vehicle
A motor vehicle, also known as a motorized vehicle, automotive vehicle, automobile, or road vehicle, is a self-propelled land vehicle, commonly wheeled, that does not operate on railway track, rails (such as trains or trams), does not fly (such as airplanes or helicopters), does not float on water (such as boats or ships), and is used for the transportation of people or cargo. The propulsion#Vehicular propulsion, vehicle propulsion is provided by an engine, engine or motor, usually a gasoline engine, gasoline/diesel engine, diesel internal combustion engine or an electric motor, electric traction motor, or some hybrid vehicle drivetrain, combination of the two as in hybrid electric vehicles and plug-in hybrid vehicles. For legal purpose, motor vehicles are often identified within a number of vehicle classes including cars, buses, motorcycles, off-road vehicles, light trucks and regular trucks. These classifications vary according to the legal codes of each country. Internationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roller Skating
Roller skating is the act of travelling on surfaces with roller skates. It is a recreation, 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. Roller skating originated in the performing arts in the 18th century. It gained widespread popularity starting in the 1880s. Roller skating was very popular in the United States from the 1930s to the 1950s, then again in the 1970s when it was associated with Disco, disco music and roller discos. During the 1990s, inline skates, inline outdoor roller skating became popular. Roller skating has often been a part of Black people, Black and LGBT history in particular. Sport roller skating includes Inline speed skating, speed skating, roller hockey, roller derby, Artistic roller skating, figure skating and aggressive quad skating. History The earliest roller skates known are from 18th-century Europe. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Skating
Ice skating is the Human-powered transport, self-propulsion and gliding of a person across an ice surface, using metal-bladed ice skates. People skate for various reasons, including recreation (fun), exercise, competitive sports, and commuting. Ice skating may be performed on naturally frozen bodies of water, such as ponds, lakes, canals, and rivers, and on human-made ice surfaces both indoors and outdoors. Natural ice surfaces used by skaters can accommodate a variety of winter sports which generally require an enclosed area, but are also used by skaters who need Ice rink#Tracks and trails, ice tracks and trails for Tour skating, distance skating and speed skating. Man-made ice surfaces include ice rinks, ice hockey rinks, bandy fields, ice tracks required for the sport of ice cross downhill, and arenas. Various formal sports involving ice skating have emerged since the 19th century. Ice hockey, bandy, rinkball, and ringette are team sports played with, respectively, a flat sl ...

Mountaineering
Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become mountain sports, sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies (including grade (climbing), grading and climbing guidebook, guidebooks) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing.

Climbing
Climbing is the activity of using one's hands, feet, or other parts of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders) to small boulders. Climbing is done for locomotion, sporting recreation, for competition, and is also done in trades that rely on ascension, such as construction and military operations. Climbing is done indoors and outdoors, on natural surfaces (e.g. rock climbing and ice climbing), and on artificial surfaces (e.g. climbing walls and climbing gyms). The sport of climbing evolved by climbers making first ascents of new types of climbing routes, using new climbing techniques, at ever-increasing grades of difficulty, with ever-improving pieces of climbing equipment. Guides and guidebooks were an important element in developing the popularity of the sport in the natural environment. Early pioneers included Walter Bonatti, Riccardo Cassin, Hermann Buhl, and Gaston Rébuffat, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sprint (running)
Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. In athletics (sport), athletics and track and field, sprints (or dashes) are races over short distances. They are among the oldest running competitions, being recorded at the Ancient Olympic Games. Three sprints are currently held at the modern Summer Olympics and outdoor IAAF World Championships in Athletics, World Championships: the 100 metres, 200 metres, and 400 metres. At the professional level, sprinters begin the race by assuming a crouching position in the starting bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running
Running is a method of terrestrial locomotion by which humans and other animals move quickly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, a slower form of movement where at least one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of Spring mass system, spring-mass mechanics is that changes in Kinetic energy, kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expect ...

Walking Bus
A walking bus (or walking school bus) is a form of student transport for young schoolchildren who, Chaperone (social), chaperoned typically by two adults (a "driver" leads and a "conductor" follows), walk in a train-like procession. The children may walk to school along a set route, with some similarities to a school bus route, with designated "bus stops" and "pick up times" at which they pick up and "drop off" schoolmates. History In Britain a group of schoolchildren walking together in a long line of pairs on an activity without stops or pickups, escorted by teachers, has been referred to as a crocodile since at least 1870. The concept of the walking bus as a way to travel to school was first introduced in Japan not later than 1962. Australian transport activist David Engwicht is often given credit for inventing the WSB system in the 1990s. It was introduced in the United Kingdom in 1998 by Hertfordshire County Council, first used by pupils of Wheatfields Junior School in St ...

Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Walking
Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined as an " inverted pendulum" gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death. Difference from running The word ''walk'' is descended from the Old English ''wealcan'' 'to roll'. In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal ...

Crawling (human)
Crawling or quadrupedal movement is a method of human locomotion that makes use of all four limbs. It is one of the earliest gaits learned by human infants, and has similar features to four-limbed movement in other primates and in non-primate quadrupeds. When crawls are used Crawling is used mainly: *When a person cannot yet walk because of being an infant *When a person cannot walk due to disability, being wounded, sick, or drunk *In very low places (caves, under a table, in a mine, etc.). Sometimes underground miners need to crawl long distances during their work *When searching for something on the ground *To get down to the ground in gardening, for maintenance or other work-related purposes which require a good reach on the ground *For stealth (camouflage and quietness) *To avoid being hit by gunfire *To lower the field of vision *As an exercise *As a token of submission *For fun or comical purposes *To reduce the risk of smoke inhalation during a fire In infants Infan ...
