Kinematic Analysis Of Shandong Elite Race Walkers In Training And Compition

Race walking was born in the19th century Britian,it development history of more than100years.Race walking was as a hobby a leisure sports in people’s life at the ealist. After100years of development for the modern Olympic Games it evolution as an official project. In this100years China made a brilliant achievements in this felids,But in recent years, it was a time of a disaster for our country’s athletes.Their athletic performance slide into the trough,even was fined from the competion many times.Butj,compared the elite’s daily training level and the level in the compition,we can found that the daily training level is more higher than the level in the compition.At the end we find that in the game is the best race-walkers result all can not reach the ideal achievements during trainingBy compared the daily training and many times the results of the game of the Shandong province sport team:race walking athletes in the competition can not play the best of thire best results. So in this paper, the second video about the daily training and the game was select in order to do technical analysis and from the kinematics compared found:1. The excellent athletes in the second game of the race walking at a significantly less than the speed of the training, and the speed of the game more than training in the obvious weight loss rate of speed.2. The excellent in the second game race-walkers in stride, average relative, the largest hip Angle and stride as indexes are obvious step frequency can not reach the level of training.3. The excellent athletes in the second game of the race, the head of focus of vertical displacement were greater than the center of gravity of the training of head displacement; In the second game of the athletes hang time obviously less than training hang time.4. The excellent walker in the game and the training of the second in the touchdown ankle Angle and from two ankle Angle no obvious differences in the index, but the competition in the rotation of the second time the obvious ankle in training the ankle longer than the second turning time, and in the second game of the ankle in training of angular velocity obviously less than half the ankle of angular velocity.
