تدريبات السرعة في اتجاه التحمل اللاكتيكي و تأثيرها على بعض المتغيرات الوظيفية و التطور الرقمي لعدائي 400 متر حواجز

Abstract EN

The researcher used speed training in the direction of of the lactic endurance and its impact on some physiological measurements as well as numbers development of 400 meters hurdles The aim of the research is to identify the effect of the speed training program in the direction of the non-tactical endurance on some of the functional variables of the 400 meter hurdles, as well as the digital evolution of the 400 meter hurdles, There are statistically significant differences between the mean and remote measures of the research group in some functional variables (the ratio of lactic acid in blood after exertion - the rate of the heart in rest - the rate of the heart after exertion directly - systolic blood pressure - diastolic blood pressure) In the direction of telemetry, there are statistically significant differences between the intermediate and remote measurements of the 400-meter hurdle range in the direction of telemetry , The sample was chosen by a deliberate method of 400 meters hurdles at the University of Beni Suef and enrolled in the Sports Union of Universities, where the number of (10) runners, and ranged in age (19: 21) , And the most important conclusions were that the speed training in the direction of the proposed lactic load of the 400 meter hurdles resulted in an improvement in the level of functional measurements in the sample in question The speed training in the direction of the proposed lactic load of the 400 meter hopper yielded an improvement in the digital level of the sample in question.

The researcher recommended that the use of speed training in the direction of the proposed tactical endurance to develop the digital level of the enemy 400 meters hurdles , Further studies of the role of special drills in the direction of non-tactical endurance are proposed to improve the functional measurements of athletes in different sports and Giving more attention to functional privacy when designing training programs for players in general and 400 meters in particular.
