Abstract

Time indicators play an important role in improving performance in hurdle running. Previous studies indicate that high-performance runners have better time indicators in some of the motor phases of obstacle running, such as the pivot phase, the flight phase, and the landing phase.

 This was attributed to the presence of deficiencies in special physical abilities and the lack of specialized training programs. Which prompted the researcher to prepare special exercises according to time indicators. The study aims to design a proposed device to measure some time indicators for 110m hurdles runners, identify the values of time indicators for 110m hurdles runners (U 20), and prepare special exercises according to the values of time indicators for 110m hurdles runners. (U 20), in addition to identifying the effect of exercises in developing some of the physical abilities and achievement of the cover man for the 110m hurdles runner (U 20), the researcher used the experimental method to suit the nature of the problem by designing a single experimental group. The research population was determined from track and field runners under 20 years old. For Baghdad Governorate, their number is (14), and (6 runners) were excluded due to some being injured, some being absent, and stopping training, leaving (8) runners. The research sample was selected using a comprehensive enumeration method, meaning that the same sample is the community, and those who train in the stadium of the College of Physical Education and Science. Sports\University of Baghdad, Ministry of Youth and Sports Stadium, Talent Care Center, and Al-Bayaa Youth Forum. Thus, the research sample constituted 100% of the community, and field research procedures included manufacturing a device for measuring the passing time of the designed cover man, its working mechanism, and how to use it, in addition to conducting physical ability tests that included ( Sprint test (30 m) from a flying start, speed increase test (3 hurdles), maximum speed test (5 hurdles), speed endurance test (8 hurdles), long jump test from a standstill on one leg, running test by jumping five steps, test (110 m hurdles) g. The special exercises were implemented on Saturday, 11/18/2023, and were completed on Wednesday, 1/10/2024. These exercises were implemented within the main section of the training unit and took 45-50 minutes ( 3) One unit per week for a period of (8) weeks, as the number of training units reached (24) units, and the duration of the training units is (8) weeks, with two intermediate courses, and (3) training units in one minor course. The researcher concluded that the training is according to the characteristics The time indicators have developed each of the physical abilities under study for the members of the research sample, and that training according to the moment in time (plyometric, ballistic, and speed training), training according to time frequency (fast strength training), and training according to length of time (speed endurance training) have an impact on the development of speed. Special for hurdles running, explosive power, speed, and special endurance. The researcher recommends emphasizing the adoption of training according to time

 characteristics and indicators in the training units and training programmes, and adopting the device designed to measure the time of crossing the barrier, as well as using it in training as it gives an indication of the crossing time
