200 metres

The 200 metres (also spelled 200 meters) is a sprint running event. On an outdoor 400 m track, the race begins on the curve and ends on the home straight, so a combination of techniques are needed to successfully run the race. A slightly shorter race, called the stadion and run on a straight track, was the first recorded event at the ancient Olympic Games. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes rely on different energy systems during the longer sprint.

In the United States and elsewhere, athletes previously ran the 220-yard dash (201.168 m) instead of the 200 m (218.723yards), though the distance is now obsolete. The standard adjustment used for the conversion from times recorded over 220 yards to 200 m times is to subtract 0.1 seconds, but other conversion methods exist.


Sprint running

Sprints are short running events in athletics and track and field. Races over short distances are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, which was a race from one end of the stadium to the other. There are three sprinting events which are currently held at the Summer Olympics and outdoor World Championships: the 100 metres, 200 metres, and 400 metres. These events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100 yard dash, the 200 m distances came from the furlong (or 1/8 of a mile), and the 400 m was the successor to the 440 yard dash or quarter-mile race.

At the professional level, sprinters begin the race by assuming a crouching position in the starting blocks before leaning forward and gradually moving into an upright position as the race progresses and momentum is gained. The set position differs depending on the start. Body alignment is of key importance in producing the optimal amount of force. Ideally the athlete should begin in a 4-point stance and push off using both legs for maximum force production. Athletes remain in the same lane on the running track throughout all sprinting events, with the sole exception of the 400 m indoors. Races up to 100 m are largely focused upon acceleration to an athlete's maximum speed. All sprints beyond this distance increasingly incorporate an element of endurance. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the accumulation of lactic acid in muscles.


Wallace Spearmon

Wallace Spearmon, Jr., (born December 24, 1984 in Robbins, Illinois, USA) is a sprint athlete, who specializes in the 200 meters. He is a two-time NCAA outdoor champion in the 200 m and won the silver medal in the event at the 2005 World Championships in Athletics. He has a personal best of 19.65 seconds for the distance, currently the seventh fastest runner of all-time and he also holds the indoor American record.

He has won the bronze medal twice at the World Championships in Athletics in 2007 and 2009. He also finished third at the 2008 Summer Olympics, but was later disqualified for stepping out of his lane.

Environment
Disaster Accident

A disaster is a natural or man-made (or technological) hazard resulting in an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment. A disaster can be ostensively defined as any tragic event stemming from events such as earthquakes, floods, catastrophic accidents, fires, or explosions. It is a phenomenon that can cause damage to life and property and destroy the economic, social and cultural life of people.

In contemporary academia, disasters are seen as the consequence of inappropriately managed risk. These risks are the product of a combination of both hazard/s and vulnerability. Hazards that strike in areas with low vulnerability will never become disasters, as is the case in uninhabited regions.
