The effect of two different methods According to a Computerized Running Training programs for interval training in lactate level in blood and performance in A 400-meter sprint for juniors
Abstract
The study aimed to: - Detecting the significance of the statistical differences in lactate level in blood and performance in the 400-meter sprint between the pre and post tests after using the method of (speed escalation and distance stabilization) According to a Computerized Running Training programs for interval training . - Detecting the significance of the statistical differences in lactate level in blood and performance in the 400-meter sprint between the pre and post tests after using the method of (distance escalation and speed stabilization) According to a Computerized Running Training programs for interval training . - Recognize the significance of the statistical differences in lactate level in blood and performance in a 400-meter sprint between the two methods (speed escalation and distance stabilization) and (distance escalation and speed stabilization) According to a Computerized Running Training programs for interval training in the post-test . The researchers used the experimental approach for its convenience to the study nature, and the research experiment was carried out on a sample of short distance runners (junior category) at the Specialized School of Athletics in Nineveh Governorate for the sports season (2019-2020) and they were (12) runners, and this sample was divided into two experimental groups through using the randomization method with (6) runners for each group, The first depends on interval training in the method of (speed escalation and distance stabilization) and the second depends on interval training in the method of (distance escalation and speed stabilization) by relying on a programmed system for the sprint in interval training . The researchers reached the following conclusions: - Interval training in the method of (speed escalation and distance stabilization) and Interval training in the method of (distance escalation and speed stabilization) made positive progress in lactate level in blood and performance in the 400-meter sprint . - Despite the positive effect of interval training in the two methods (speed escalation and distance stabilization) and (distance escalation and speed stabilization) there was a relative superiority of interval training in the method of (speed escalation and distance stabilization) in the special endurance consisting of (speed endurance and strength endurance) and performance in Sprint 400 meters . The researchers recommended a set of recommendations, the most important of which are : - The use of interval training in the method of (speed escalation and distance stabilization) and not being satisfied with the use of interval training in the method (distance escalating and speed stabilization) when training a 400-meter sprint because of its importance in developing the performance in the 400-meter sprint, as well as its creation For functional adaptation in relation to blood lactate level after improvement in performance. - measuring the level of lactate in the blood in the training of runners from time to time, as a functional indicator that helps in detecting the level of training status and identifying the adaptation and recovery of runners, in order to evaluate the training process. - The possibility of relying on the Computerized Running Training programs for interval training in designing interval training methods and curricula for all short-distance runners, including 400-meter sprinting for all levels and age groups .
