The Impact of Mechanical Training in Accordance with Regulating the Optimal Stride Length in the First and Second Straight Phases on the Achievement of 400 Meter Events for Men

Abstract

The significance of this research is primarily anchored in the sustained interest in athletic achievements and the ongoing process of their development through the application of biomechanics and its integration into the science of sports training. The study aims to focus on the regulation of the optimal stride length according to the runner's height, necessitating specialized mechanical training tailored to specific distances when sprinting in both the first and second straight sections of the 400-meter event. This is proposed through the suggestion of six interval distances (90, 80, 70, 60, 50, 40 meters). The research problem delves into the importance of training 400-meter sprinters by leveraging the first and second straight sprints with an ideal stride length, calculated as the runner's height × 1.22 according to James Hay's equation, and utilizing this to compensate for the deficit incurred during curve running due to changes in running mechanics to overcome centrifugal force. In light of their research objectives, the authors hypothesized that there would be no significant statistical differences between the pre-test and post-test measurements of male 400-meter sprinters. The researchers employed an experimental method with a single group to suit the nature of the research problem. The sample consisted of six athletes representing (Army, Police, Militia) clubs. The training program included 24 training units over eight weeks, with an average of three training units per week. The researchers concluded several key findings, notably that the designed training had a significant impact on the sample group, as evidenced by the significant differences observed. In light of the results, the researchers recommend the application of these training methods according to the special equation for calculating the optimal stride length in other activities to enhance performance towards better outcomes.
