Middle-distance Running
Middle-distance running events are Track and field#Running, track races longer than Sprint (running), sprints, up to 3000 metres. The standard middle distances are the 800 metres, 1500 metres and mile run, although the 3000 metres may also be classified as a middle-distance event. The 1500 m came about as a result of running laps of a 400 m outdoor track or laps of a 200 m indoor track, which were commonplace in continental Europe in the 20th century.1500 m – Introduction IAAF.

Swimming (sport)
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water (e.g., in a sea or lake). Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle. Swimming each stroke requires a set of specific techniques; in competition, there are distinct regulations concerning the acceptable form for each individual stroke. There are also regulations on what types of swimsuits, caps, jewelry and injury tape that are allowed at competitions. Although it is possible for competitive swimmers to incur several injuries from the sport, such as te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triathlon
A triathlon is an endurance multisport race consisting of Swimming (sport), swimming, Cycle sport, cycling, and running over various distances. Triathletes compete for fastest overall completion time, racing each segment sequentially with the time transitioning between the disciplines included. The word is of Greek language, Greek origin, from τρεῖς or ''treis'' (three) and ἆθλος or ''athlos'' (competition). The sport originated in the late 1970s in Southern California as sports clubs and individuals developed the sport. This history has meant that #Nonstandard variations, variations of the sport were created and still exist. It also led to other three-stage races using the name triathlon despite not being continuous or not consisting of swim, bike, and run elements. Triathletes train to achieve endurance, strength and speed. The sport requires focused persistent and Sports periodization, periodised training for each of the three disciplines, as well as combination ...

Flat Racing
Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance is in the gambling associated with ...

Orienteering
Orienteering is a group of sports that require navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering. Orienteering is included in the programs of world sporting events including the World Games (see Orienteering at the World Games) and World Police and Fire Games. History The history of orienteering begins in the late 19th century in Swede ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron (golf)
An iron is a type of club used in the sport of golf to propel the ball towards the hole. Irons typically have shorter shafts and smaller clubheads than woods, the head is made of solid iron or steel, and the head's primary feature is a large, flat, angled face, usually scored with grooves. Irons are used in a wide variety of situations, typically from the teeing ground on shorter holes, from the fairway or rough as the player approaches the green, and to extract the ball from hazards, such as bunkers or even shallow water hazards. Irons are the most common type of club; a standard set of 14 golf clubs will usually contain between 7 and 11 irons, including wedges. Irons are customarily differentiated by a number from 1 to 10 (most commonly 3 to 9) that indicates the relative angle of loft on the clubface, although a set of irons will also vary in clubhead size, shaft length, and hence lie angle as the loft (and number) increase. Irons with higher loft than the numbered irons are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landscape Painting
Landscape painting, also known as landscape art, is the depiction of natural scenery such as mountains, valleys, trees, rivers, and forests, especially where the main subject is a wide view—with its elements arranged into a coherent composition. In other works, landscape backgrounds for figures can still form an important part of the work. Sky is almost always included in the view, and weather is often an element of the composition. Detailed landscapes as a distinct subject are not found in all artistic traditions, and develop when there is already a sophisticated tradition of representing other subjects. Two main traditions spring from Western painting and Chinese art, going back well over a thousand years in both cases. The recognition of a spiritual element in landscape art is present from its beginnings in East Asian art, drawing on Daoism and other philosophical traditions, but in the West only becomes explicit with Romanticism. Landscape views in art may be entirely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-range
In statistics, the mid-range or mid-extreme is a measure of central tendency of a sample defined as the arithmetic mean of the maximum and minimum values of the data set: :M=\frac. The mid-range is closely related to the range, a measure of statistical dispersion defined as the difference between maximum and minimum values. The two measures are complementary in sense that if one knows the mid-range and the range, one can find the sample maximum and minimum values. The mid-range is rarely used in practical statistical analysis, as it lacks efficiency as an estimator for most distributions of interest, because it ignores all intermediate points, and lacks robustness, as outliers change it significantly. Indeed, for many distributions it is one of the least efficient and least robust statistics. However, it finds some use in special cases: it is the maximally efficient estimator for the center of a uniform distribution, trimmed mid-ranges address robustness, and as an L-estima ...
