Research On Specific Strength Training Means Of Lower Extremity 400M Sprinters

Modern sports progress needs strength quality healthy development as the support, to develop the strength of any sport are key elements for the sprint, which is a special sport, the athletes of the explosive force and initial force is more strict. This raises the clear direction for the study of the majority of workers in sports. After the scientific examination of sports practice, the technical requirements of correctly understanding the sprint and feature is a scientific basis for the design and selection of training plan, and chooses the special features of the training theory and technology theory, and use it as the basis for the preparation of training on the training plan and adjustment. To promote sports training effect is remarkably enhanced. Correct understanding of the characteristics of dash technique project, the selection efficiency of sprint specific strength training methods is to improve the sprint performance important ways of training.The 400 meter sprint is one of the sprint track, is recognized as the athletic competition in the most difficult to practice project, between sprint and middle distance of 400 meters, is on a project for the most demanding physical quality of the athletes. But the special strength training, only the content arrangement of training strength and special characteristics of combined, can better achieve the ideal training effect, it also can promote effectively improve athletic performance, this paper will take the special strength training method of lower limb 400 meter sprinter as observation points, we focus on the special strength training method of lower limb 400 meter dash athletes, to find out the right 400 meters of special strength of lower limb strength training content, which is the theory basis and design selection of 400 meters sprint special strength training and training techniques can provide reference.According to research needs, this article uses the literature material law, with the observation method, expert interview method, mathematical statistics method, questionnaire survey method, the experiment contrast method, lower limb strength training of sprint record finishing special means and prominent features, the effectiveness of the method by using the method of data comparison for the 400 meter dash and lower extremity strength training are selected and determined the final conclusion of the study.The special strength training of sprint project, a single from the training methods, distinction is not obvious, if there is a subtle difference between observation from the special characteristics and requirements of the project, so we have to be in the training of special forces and special forces of lower extremity were analyzed carefully, so as to find out the scientific training methods where. Practice shows that the means of a single repeat training special strength training of 400 meter sprinter were not significantly improve the role, which requires us in the process of training special strength, must adopt composite science reasonable means, in order to promote the 400 meter sprint athlete special strength and improve the performance of.The team observed, consulting relevant experts and access to a large number of domestic and foreign literature method, technical means of screening the present stage more popular sprinters leg training, found by comparing the special strength training of sprint of lower extremity in action structure and the muscle work style and special technical features sprint lower limb is very similar or consistent. Particularly important practice proved that the special lower limb strength training means sprinters on specific performance improvement. According to the special forces of lower extremity means choose suitable for different characteristics, the sports training to achieve a more ideal effect, with a view on the athletic field for the state and national glory.At present in our country the sprint training, consistent application of the lower limb strength training means of requirements and special lower limbs technology in the technical movement, muscle force and so on, in line with the development of lower extremity strength and training means, it has proved that China expert and sprint coaches on the dash of special strength training, have understanding and in-depth understanding.
