Throughout the development of competitive sports world, as one of the oldest sports in the sprint level of development has expanded rapidly. Every increase in athletic performance limits of the new challenges to human, but also higher indicate future goals, coaches heavier responsibility, exercise training also will be more difficulties. World sprint level, rely on advances in sports science and technology, especially the physical training methods of modern science and the innovation and development. Modern physical training is the process of training a multi-disciplinary knowledge-based, the application of advanced scientific training methods and means to develop the athlete's body shape, body function and quality of the training exercise, it and technical training, tactical training, psychological training constitute a complete training system. Scientific system of strength training is an important part of physical training, strength, quality is the speed, endurance, agility, flexibility are the basis of quality is the cornerstone of the development of competitive sports, strength training in competitive sports concern the development processStrengthen the leg muscles has long been considered a prerequisite to improve sprint performance, but Sprint study reveals that specific strength training, clearly the shortcomings of current training in biomechanics of sprint action for the error structure of understanding. On "Strength Training" in the understanding of the existence of bias, plus the training methods and means too focused on "the barbell squat exercise" so that in the human evolutionary process, the muscle had a strong position in the thigh muscle strength more powerful group, the thigh After the group of muscles because of the lack of training methods and means to make it with the thigh muscle strength before the gap between the larger group. Traditional strength training methods and means of breaking the power of human muscle balance of the original strength, strong stronger, the weak weaker, which is the group of sprinters thigh muscle injury after one of the factors frequently, in large Technique of the right to play, a "strong so that no" phenomenon, thereby affecting the effects of strength training sprint, leading to improved sprint performance is slow, or even stagnant.In this paper, after the sprinter group of the thigh muscle strength training as the research object, using literature, expert consultation and comparative analysis of law, first with Sprint characteristics of the project, technical features, competitions and other characteristics, strength training in the premise of a big trend Next, follow the sprint strength training principles for strength training the current status of Short, problems and the current training methods and means used to analyze the advantages and disadvantages; Second, from the anatomy, biomechanics perspective on the thigh muscle group anatomy grasp the thigh muscle group in the sprint after a single step cycle characteristics and functional properties of force; Finally, based on strength training of the relevant theory, design and development group of sprinters thigh muscle strength after the ways and means, and with sprint training practices are summarized in thigh muscle strength after the development of the process group should pay attention. The results show that: the traditional strength training methods and means Sprint, leading sprinters before the thigh, after the group of muscle strength imbalances, strong stronger and the weak weaker, thigh before and after muscle and thigh muscle strength after more than group closely related to muscle damage. Thigh muscle group anatomy, physiology and action in the work of sprint technique the existence of functional form of lack of initiative, plus the lack of training methods and means, the thigh muscle injury after the high frequency group of one of the reasons. Strength training coaches were in the Sprint, in the following strength training and balance the principles of comprehensiveness, the increased thigh muscle strength training group strength training in the sprint in the proportion of the actual situation based on athletes training volume and intensity of reasonable arrangement thus making the thigh muscle strength after the group be a qualitative improvement of strength training to achieve the most optimal state for the prevention of group of sprinters thigh muscle injury and improve athletic performance to provide strong protection.Recommendation: After the group of thigh muscles during the training process, according to the different training phase, control the volume and intensity training, strict training requirements; attention to a number of development options for the line of thigh muscle strength after the group training methods and means and to develop speed and strength and speed strength endurance-based; also focus on thigh muscle strength after the group's recovery after training exercises, specialized training process can be interspersed in the relaxation exercises, strength training makes the best, for the next stage training programs conducted, and pave the way after the special exercises. |
