Introduction
Track and field is a sport that contains many different disciplines, including track sprints, track distance races, and field events, which include javelin throwing and pole-vaulting, among others. While predominantly an individual sport (except for relay races), in high school athletics, track and field athletes earn points based on their finishes toward an overall team score. Each athlete in each event should perform their best for two reasons: their individual result and their team score.
Running and walking, while they seem similar, are two different modes of movement. Running is ballistic in which there are two phases: (1) a flight phase (also known as a recovery phase) with no contact with the ground, and (2) a support phase when one leg is on the ground (Plisk, 2008). This differs from walking, as there is no flight phase.
Even within running there are two different disciplines. Distance running is at slower speeds and requires great focus on economy of movement, whereas sprinting is at maximal speeds with little focus on economy (Bushnell & Hunter, 2007). Because of the differing goals of these types of running, the techniques of distance running and sprinting are unique. A more acute hip angle is noticed with sprinters when compared with distance runners, because of 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 amount of time in the support phase, the time braking is diminished.
A race is scored by the amount of time it takes an athlete to cover the pre-described distance. Typically, the time is measured from the starting gun to t...

In the world of high school running, there are two types of runners: cross country runners and track runners. I am both, as I have been in cross country since seventh grade and track since first grade. I know how it feels to train and compete in both, and I have come to a conclusion that track & field is way better than cross country.
The most famous study on the biomechanics of T-Rex was by Hutchison and Garcia. They discussed whether or not the short-armed T-Rex could run very fast considering its massive size. Through this hypothesis a model was created. The model designed by Hutchinson and Garcia used physics and biological equations to calculate the amount of leg muscle an animal needs to remain balanced during fast running. While running at great speeds an animal pushes against the ground in order to support itself. This also means that the animal exerts force proportional to its weight every time its foot hits the ground. As a result, the ground pushes back upwards on the leg with a vertical force. That vertical force, called a ground reaction force, is about 2.5 times body weight during fast running.

One sport you may not have considered for your High School activities is track. Track is a sport with an array of benefits for your body. People from all over the world participate in many running events including sprinting, middle distances, long distances, relay races, hurdles, steeple chasing, and race walking. I will go into more detail under the subject of sprinting a bit later. First, I will speak to you about the preparation it takes in order to get into track sprinting shape.
In conclusion, this brief review suggests that the literature is contradictory in the theory that muscle fibres during a CMJ are less beyond optimum length in comparison to SJ, in turn allowing an increased force during the initial part of their shortening, causing the storage of elastic energy that can then be reutilized during the propulsion phase, therefore further research is necessary. However, it does seem that from a biomechanical perspective the active state development during the preparatory countermovement in a CMJ may increase force by the hip extensors and more work during shortening in CMJ and therefore a greater vertical force and jump height.
The speed of the runner is very easy to determine. It's only stride length times stride frequency, for example if you travel five feet in one stride and you take three strides per second you're speed will be 15 feet per second. Basic math. Although, there are three different types of stride lengths, takeoff, flight, and landing distance. Takeoff distance is the distance that the body's center of mass is ahead of the toe of the front foot at the instant the back foot leaves the ground. The flight distance is the distance that the body's COM travels while the runner is in the air. The landing distance is the distance that the toe of...
The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life

The use of the six principles of training by a 100m sprinter would greatly improve the athlete’s performance. This is because the progressive overload, specificity, reversibility, variety, training thresholds and warm up/cool down principles all greatly affect the performance of any athlete. The principles of training can be employed in order to improve all aspects of fitness, from flexibility to strength and aerobic endurance.
Creative new training methods, developed by coaches, athletes and sport scientists, are aimed to help improve the quality and quantity of athletic training ( Kellmann, 2010, p.1). However, these methods have encountered a consistent set of barriers including overtraining ( Kellmann, 2010, p.1). Due to these barriers, the need for physical and mental recovery in athletics brought an increasing attention in practice and in research ( Kellmann, 2010, p.1).

Everybody has at least sprinted a short distance on a track or have run at least a lap on a track for a period of time. Many people that have play sports have experienced sprinting or long distance running. Some sports like basketball, baseball, football and sprinting event in track require short burst of speed. While sports like cross country or some events for track and field require endurance for these events. In the Olympics for example there are many differences between sprinters and long distance runners. These differences include physical differences, motion, and different workout plans between sprinters and long distance runners.
