Abstract

Head the ball technology is a basic technology in football, plays an important role in the Modern football. The same time, because of its use of the parts of the particularity been widespread concern. The back bow stages football head ball technology is the most important, the most critical stage of study helps to strengthen this stage to improve the technical level of athletes, sports injury prevention, and provide a theoretical basis to explore the best football head ball effect. In this paper, 12 subjects positive side direction to the ball in place, standing jump and head the ball of the run-up to jump three forms of technological change characteristics for the study, by three-dimensional video analysis, electromyography measurements and two The two methods of synchronization test, the technical features of the critical stage of the football head ball. Forward to the ball, place the head ball technology in the technical structure is relatively easy to master a technology, the technology lies in the neck fixed. The take-off stage and back bow stage standing jump head the ball technology is the key stages of technology, takeoff directly influences the entire air operation technology stereotypes; \muscles play a major role in the technical operation of the head ball the air technical movements, the completion of the two opposite movements require coordination of the lower limbs links; overhead ball stage to maintain the fixed neck still effective use of momentum transfer, and prevention of sports injuries the key. Main power comes from the torso to the hip axis of the swing, the run-up to jump is to increase the level of speed, run-up jump ball head the ball technology is the basis of the run-up to jump head the ball technology; dorsal arch stage is to head the ball technology The key technologies, full back arch technique is the main factor affecting the ball in the air movement, the two opposite movement is indispensable; the dribbler stage neck fixed can fully utilize the trunk is passed to the momentum of the head and can effectively prevent sports injuries. The significant effect of the change in direction of the head ball technology, it makes the head ball technique Actions structure changed, mainly in the rear of the back bow stage slew time, after the swing amplitude. Direction changing, the speed of the swing of the back bow stages torso also appear significantly decreased, especially in the rear of the torso swing phase, changes in the speed of the swing of the head is not obvious. The change in the rate of changes in the speed of the head and torso showing inconsistencies lost a role, i.e. with the change in direction of the neck of the fixed motion radius weakened subjects, resulting in a loss of momentum transfer. With the change of direction caused by the decline in the ability of the body movement, in addition to the individual aspects of coordination with the impact of outside, the body did not form the correct action dynamic stereotype is also one of the main reasons. EMG learn, should strengthen the front and the muscles of the exercise, to play the role of the core muscles, the formation of the correct dynamic stereotype; symmetrical exercises to strengthen the muscles of the left and right sides of forces, to ensure a reasonable fit mode mover muscle against muscle.
