WHAT ARE THE OPTIMAL BIOMECHANICS OF HURDLING? By understanding the biomechanics of a particular the biomechanics of sports techniques pdf it allows the athlete to enhance their performance as well as prevent any injuries.

The athletes at the starting block and in the race are well linked to this law. The athlete is at rest whencommencement in the block, as they are not moving. Which resulted the athletes to have no external forces. The athlete runs at a constant speed for majority of their race, because of inertia the athlete continues at a consistent speed. The mass of an athlete affects their performance within most track and field event. Mass is the crucial component to triumph in a hurdling race. In hurdling there are restricted for time to correct anerror that they may make earlier in the race as it is about meticulousness.

One of the most significant parts of the race is the beginning blocks. The athlete forcefully pushes off the block then that force pushes the athlete forward. The second most important part is the take off. When the hurdler is taking off they are pushing forcefully on to the track where that force then pushes the hurdler forward. After the brief cover of biomechanics and how it fits into Newton’s Three Laws of Motion there are five key principles of biomechanics to be concentrated on: force, motion, momentum, leverage and centre of gravity.

Within all sports force and motion work closely together. Sprint hurdles being a good example of these two biomechanical principles work together to allow the athlete to successfully clear the hurdle. Force produces movement and a force is purely a pull or a push. You cannot see force as it affects it produces you are mindful of it. When running a hurdle race the moment the athlete explodes out the block to the second they finish the race the force and motion are being utilised. The athlete takes off the block exerting force downwards with the stationary block pushing back and therefore acceleration occurs as shown in figure 2.

With every stride the athlete takes they exert a force on the ground propelling them forward. With the first few strides out of the blocks the athlete should have a slight lean in their posture while running. If the athlete were to pop up into an upright position right away, they would be opening themselves up into superior amount of air resistance. The lengthier the athlete stays streamline the quicker they can increase speed momentum. Momentum is a quantity of motion a body has, another key biomechanical principle involved in a hurdle race.

The more momentum the athlete is able to produce the quicker they will be able to move over a distance. In sprints hurdles it is important for the athlete to gain, as much momentum as they can in the first 10 meters, as getting to the first hurdle first is extremely important. Angular momentum is the amount of angular or rotating motion a body has and is the produce of the instant of inertia and rotating velocity. When the arms are bent in the sprint of hurdling their inertia is less compared to if they were to be running with straight arms.

When hurdling the athlete have two types of levers, the arm and the leg lever. On the signal step the athlete is in the blocks, the positioning and the angles of the athlete’s legs are significant to the start. Another instants of the leg lever is when the athlete is running between the hurdles. When the athlete places their lead leg on the ground the back leg follows, coming around the front with an angle of 90 degrees while the other is adjusted out to 180 degrees. When sprinting it is crucial for the athlete not too over stride. Over striding means that your stride is longer then what it should be in optimal condition. The angle of the leg should be no more then 90 degrees thus when it is over 90 degrees the athlete over stridesthis interfering with their running technique.
