Relay Race
A relay race is a racing competition where members of a team take turns completing parts of racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming, cross-country skiing, biathlon, or ice skating (usually with a baton in the fist). In the Olympic Games, there are several types of relay races that are part of track and field, each consisting of a set number of stages (legs) (usually four), each leg run by different members of a team. The runner finishing one leg is usually required to pass the next runner a stick-like object known as a "baton" while both are running in a marked exchange zone. In most relays, team members cover equal distances: Olympic events for both men and women are the 400-metre (4 × 100-metre) and 1,600-metre (4 × 400-metre) relays. Some non-Olympic relays are held at distances of 800 m, 3,200 m, and 6,000 m. In the less frequently run medley rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ladder Logic
Ladder logic was originally a written method to document the design and construction of relay logic, relay racks as used in manufacturing and process control. Each device in the relay rack would be represented by a symbol on the ladder diagram with connections between those devices shown. In addition, other items external to the relay rack such as pumps, heaters, and so forth would also be shown on the ladder diagram. Ladder logic has evolved into a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. Ladder logic is used to develop software for programmable logic controllers (PLCs) used in industrial control applications. The name is based on the observation that programs in this language resemble ladders, with two vertical rails and a series of horizontal rungs between them. Ladder diagrams were once the only way to record programmable controller programs, but today, other forms are standardized in IEC 6113 ...

Butterfly Stroke
The butterfly (shortened to fly) is a List of swimming styles, swimming stroke swum on the chest, with both arms moving symmetrically, accompanied by the butterfly kick (also known as the "dolphin kick") along with the movement of the hips and chest. It is the newest swimming (sport), swimming style swum in competition, first swum in the early 1930s and originating out of the breaststroke. Speed and ergonomics The butterfly stroke boasts a higher peak velocity than the front crawl, owing to the synchronous propulsion generated by the simultaneous pull/push of both arms and legs. However, due to the pronounced drop in speed during the recovery phase, it is marginally slower than the front crawl, especially over extended distances. Furthermore, the butterfly stroke demands a different level of physical exertion, contributing to its slower overall pace than the front crawl.

4 × 400 Metres Relay
The 4 × 400 metres relay or long relay is an athletics track and field, track event in which teams consist of four runners who each complete 400 metres or one lap, totaling 1600 meters. It is traditionally the final event of a track meet. The first leg and the first bend of the second leg are run in lanes. Start lines are thus staggered over a greater distance than in an individual 400 metres, 400 metres race; the runners then typically move to the inside of the track. The slightly longer 4 × 440 yards relay, on an Imperial units, Imperial distance, was a formerly run British Commonwealth and American event, until metrication was completed in the 1970s. Format Relay race runners typically carry a relay baton which they must transfer between teammates. Runners have a 20 m box (usually marked with blue lines) in which to transfer the baton. The first transfer is made within the staggered lane lines; for the second and third transfers, runners typical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4 × 100 Metres Relay
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. Each runner carries a relay baton. Before 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017, that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, and the incoming runner cannot touch it after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colours and style are only "recommended". While most legacy tracks will still have the older markings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athletics (sport)
Athletics is a group of sporting events that involves competitive running, jumping and throwing. The most common types of athletics competitions are track and field, road running, cross country running, cross-country running, and racewalking. The results of racing events are decided by finishing position (or time, where measured), while the jumps and throws are won by the athlete that achieves the highest or furthest measurement from a series of attempts. The simplicity of the competitions, and the lack of a need for expensive equipment, makes athletics one of the most common types of sports in the world. Athletics is mostly an individual sport, with the exception of relay (athletics), relay races and competitions which combine athletes' performances for a team score, such as cross country. Organized athletics are traced back to the ancient Olympic Games from 776 BC. The rules and format of the modern athletics events, events in athletics were defined in Western Europe an ...
