The Characterics Of China Canoe Slalom National Team Athletes' Full-course Distance Speed Structure And The Reasons Of Them

Canoe Slalom is developing in China.However,our players still have some gaps compared with the outstanding players in the world.The paper analyzes and compares the national players of our country with the outstanding players in the world by using Dartfish comparative analysis software.By analyzing and comparing the finishing speed,the number of paddle and the skill of every part,the study sums up China canoe slalom national team players' speed structure of the whole distance and makes the conclusions as follows:(1) By analyzing the collected veidos and interviewing the coaches and the athletes of national team,the whole speed structure of canoe slalom competition is divided into the speed of going through upstream gates and the speed of going through downstream gates according to the direction of going through the gates.According to the relationship between the gates,it is divided into the speed of finifhing all combination gates and the downstream speed.According to the sequence of finishing the routine and the distribution of difficulties,it is divided into the speed of first half and the speed of second half.(2) By comparison,there is no obvious gap between our players and the outstanding players in the world in the aspect of downstream speed.But our players are not able to distribute the energy,use the right skills reasonablly and the ability to follow the current is not good.As a result, they consume too much energy in this part.After excessive consumption of energy,they can not slow down and buffer in front of the upstream gates and can not follow the current correctly and speed up when the canoe goes through the gates.Therefore,the speed of upstream is too slow.(3) According to the relationship between the gates,it is divided into the speed of finishing all combination gates and the downstream speed. In the downstream part,our national players is as good as the outstanding players in the world.However,they can not choose the right paddle points and right time to paddle and arrange the energy reasonablly which results in excessive consumption of energy.In the part of combination gates, the national team players can not use the right skills and follow the current correctly,they consume the energy excessively.The speed is slower than the outstanding player in the world obviously.(4) According to the sequence of finishing the routine and the distribution of difficulties,it is divided into the speed of first half and the speed of second half.Compared with the outstanding players,our players' first half speed is as good as them.But they can not use the skills correcly and follow the current when go through the upstream gates and combination gates in the first half.As a result,they consume the energy excessively.In the second half,our players' speed slow down too much and make too many mistakes,especially when they go through the downstream gates and combination gates in the second half.As a result, it is difficult for our players to speed up in the second half because of the excessive consumption in the first half.
