Comprehensive Analysis of Sprint Running Biomechanics in Sports

This report provides a comprehensive analysis of sprint running biomechanics, examining various factors that contribute to an athlete's performance. It begins with a literature review, summarizing key findings from research on sprint running techniques, including kinematic data, ground reaction forces, and muscle torque. The report then presents an observation of a 22-year-old athlete, detailing their starting position, leg angles, and movements during the sprint. It highlights the importance of optimal anthropometric characteristics, training methods, and external factors such as clothing and running surface. The discussion incorporates findings from the literature review, emphasizing the impact of biomechanical factors on an athlete's ability to maximize speed and cover the maximum distance in the shortest possible time. The report concludes that rigorous training, proper clothing, and suitable footwear are crucial for improving sprint performance. The report also references various studies, including research on Usain Bolt's running style and the effects of training methods on stride parameters.

Discussion:
Sprint running is an important factor when it comes to the athlete to run in major
sports events like Olympics. The observation drawn from the 3D kinematics where a 22 year
highly energetic athlete was observed through video capture shows certain specific outcome.
It has been found that at the state of on the mark, or the starting position, the athlete begins
with a distance of 0.65m between the legs and with the angle of 105 degree at the keen. This
shows that at the time of starting the race, an athlete has a greater angle and aims at covering
the maximum possible distance within the short time. In the article, Coh (2019) examined the
running pattern of the fastest running athlete, Usain Bolt and pointed out that it is a result of
the combination of optimal anthropomertric characteristics that helps a person to be a
successful athlete. At the same time, Cetin, Hindistan and Ozkaya, (2018) commented that
training of the athlete is as important as any other factor. There is a difference in the running
ability of a person on a plain land and that in a higher altitude. Therefore, a sprinter is often
given the training to be able to perform at different levels of ground and alongside, the other
factors that helps to make him a perfect athlete.

Next, as per the observation, as soon as the athlete covers a distance of 1.50 m within
the time of 840 milisec, it has been noticed that the angle between the thigh and the lower leg
decreases to 92 degree. Thus, there is a difference of 13 degree as soon as the person starts
running. It can be highlighted here that as the run begins, the athlete aims at covering the
maximum distance within the shortest possible time. This is easily visible in the movement of
the athlete where he constantly changes the angle of his various body parts like the leg or the

SPORTS BIOMECHANICS
hands in order to best fit the environment where he is running and achieves the best possible
result in terms of lesser time and more distance. In this respect, the findings of Haugen and
Buchheit, (2016) can be taken into consideration where they clearly mentioned that there are
several external factors as well that equally contributes in the success or the failure of an
athlete. This is the reason that the athletes are found to wear body fitting clothes so that the
resistance of the air can be reduced to the maximum level. Moreover, they are also opined to
use sports shoes with high grip that would provide high grip to the surface area and these
external factors can be easily avoided. Similarly, it has been observed that as the observant
started running and when his other leg (here, right) came forward, the angle of the leg again
increased to 100 degree with his upper body tilted towards front to cover the maximum
distance possible with one attempt. As opined by Pavei et al., (2019) that the mechanical
power of an athlete increases linearly with the increase in the mean sprint velocity. The
inertia of the limbs decreases due to the function of the distance within the sprint and this is
the reason that the angle increases and decreases as per the changes in the movement.
Conclusion:
The above discussion based on sprint running or sprinting as a fundamental skill that
creates the basic for an athlete to run and perform the best as per their ability. However, it has
been clearly observed that there are various factors that increase the ability of an athlete to
perform better. With the help of the observation based on the set up and the information
gained from the literature review, it has been clearly established that the success of an athlete
depends on the bio mechanism as adopted by the athlete. The aim of an athlete is always to
cover the maximum distance in the minimum possible time and in order to get this these
athletes are found to adapt various methods. It can be said that rigorous training under the
supervision of a coach who shall be recording the movement of the athlete is important. The

SPORTS BIOMECHANICS
correct selection of clothing and shoes depending on the running surface are other important
factors other than the bio--mechanic factors.
