A comparative study between different timing devices for completing the 100-meter freestyle race for runners under 20 years old

Abstract

The training process has recently developed, as training has become dependent on modern devices that affect the type of performance, in addition to relying on modern methods that were previously unfamiliar. Therefore, training and preparing athletes is an important and necessary matter in order for them to rise to high levels of physical and skill preparation, which qualifies them to compete with high efficiency. On this basis, achievements have developed with the development of training science and its interaction with other sciences in the service of achieving the training process. One of the events that has witnessed great development in the field of athletics is the 100m event, as this event is characterized by complex performance. Sprinting events are among the most exciting and thrilling athletics events due to the strong competition in them. Accuracy in timing sports events is an essential element in determining winners and evaluating athletic performance. Since the emergence of sports races, many methods have been invented to ensure timing accuracy, starting with manual timing that depends on human reaction, and reaching advanced technological devices such as the photofinish device. Running races require extreme accuracy in measuring time to ensure fairness and accuracy in results, as timing plays a crucial role in determining winners and achieving records. Running competitions require high accuracy in timing to ensure fairness in results. In this study, the accuracy of three types of devices used in timing the 100-meter race for youth was compared: a new innovative device, the traditional photofinishing device, and manual timing.

The importance of the research lies in the manufacture of a timing device similar to the work of the photofinishing device by the researchers and conducting a comparison in timings between the different devices used in the races (photofinish device, manual timing) in addition to the device invented by the researchers.
