IntroductionAthletics is a sport that contains many different disciplines, including track sprints, distance track events, and field events, which include javelin throwing and jumping with the auction, among others. Although predominantly an individual sport (with the exception of relay races), in high school athletics, track and field athletes earn points based on their placings toward an overall team score. Every athlete in every event should give their all for two reasons: the individual result and the team score. Running and walking, although they seem similar, are two different modes of movement. Running is a ballistic method in which there are two phases: (1) a flight phase (also known as recovery phase) without contact with the ground and (2) a support phase when one leg is on the ground (Plisk, 2008). . It differs from walking because there is no flight phase. Even in running there are two different disciplines. Long-distance running occurs at slower speeds and requires close attention to economy of movement, whereas sprinting occurs at maximum speeds with little attention to economy (Bushnell & Hunter, 2007). Because of the different goals of these types of running, the techniques of distance running and sprinting are unique. A sharper hip angle is noted in sprinters compared to marathon runners, due to the need to limit ground contact time, which is a braking force, during a sprint (Bushnell & Hunter, 2007). In a sprint (or any race, for that matter), the goal is to finish as quickly as possible. By limiting the time in the support phase, braking time is reduced. A race is scored based on the time it takes an athlete to cover the set distance. Typically, time is measured from the starting shot to the center of the card of runners at equal and maximum speeds.
