As for the m sprint , the m world record has improved significantly over time as track surfaces and running shoe design has improved, as well as the positive impact of advanced training methods and sports science research. Early world records for the sprint events used only hand timing, which was generally only accurate to one-tenth of a second. The men's world record holder is Usain Bolt of Jamaica, who ran The m race times can be affected by the wind, and any time that is recorded with an excess tailwind will not be considered a world record. Records set at altitude as also included, even though the thinner air is an advantage in this event. Before electronic timing was invented and became standard, record times were recorded using hand-held stopwatches. Race records from events over yards

The metres , or meter dash , is a sprint running event. On an outdoor metre racetrack, the race begins on the curve and ends on the home straight , so a combination of techniques is 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 m places more emphasis on speed endurance than shorter sprint distances as athletes predominantly rely on anaerobic energy system during the m sprint. Similarly to other sprint distances, the m begins from the starting blocks. When the sprinters adopt the 'set' position in the blocks they are able to adopt a more efficient starting posture and isometrically preload their muscles. This enables them to stride forwards more powerfully when the race begins and start faster. In the United States and elsewhere, athletes previously ran the yard dash The standard adjustment used for the conversion from times recorded over yards to m times is to subtract 0. Another obsolete version of this race is the metres straight , which was run on tracks that contained such a straight. Initially, when the International Amateur Athletic Association now known as the International Association of Athletics Federations started to ratify world records in , only records set on a straight track were eligible for consideration. In , the IAAF started to recognise records set on a curved track. In , the straight record was discarded.
