| With200m short the project will be held soon the London games for the first time in the Olympic programme, the game than ever before competition and intensity of the500m and1000m project has been improved a lot. Sprint link of the original research in canoeing seldom covered, but with tactics system consummation, the match itself needs, sprint link more and more become a key link, as the last part of the game, the sprint link can be directly to the match results, this paper hope through to sprint technical characteristics of research and analysis, for our country’s kayak training game offer some reference and reference to China’s kayak team impact2012London Olympic medals to provide a low power.This paper uses the research methods:the three set model for PC350E at SONY camera, two sets of athletes sprint for fixed-point fixed-focus shooting, the other a track shoot camera for the whole project to match the track shoot. Filming for25frame frequency/s, breakout for50games after/s. Using German SIMI°Motion7.50sports action analytical system, the movement of the video collection of the human body each positioning point by point point into the analytical frame by frame, and obtain the sprint phase player a propeller cycle and the phase displacement, time, speed, the blade into the water and outlet Angle Angle of kinematics parameters.The results show that:1. Kayak (static water) sprint technology can be classified into two categories total of eight little types, it is respectively by boat speed leading type divided into high frequency high-speed oars, instantly acceleration, basic uniform sprint, slow down, sprint, slowing slide by and body posture of the stability of the leading divided into stance sprint type, after sitting sprint type, on the cabin, out of the bottom of the sprint type.2. The high frequency of high-speed oars sprint type characteristic frequency and boat oars is speed are kept at a very high level, the whole process and the players on the sprint phase and not much difference paddling, players keep a good body posture, did not appear obvious intense shaking body, in a study of six high frequency high-speed players paddle, kayak players paddle in147the average frequency oars/min, boat in an average speed of6.03m/s, rower oars frequency in73average oars/min, boat in an average speed of5.35m/s, the common characteristic of players paddle movement is a steady rhythm, the effect is good, strong ability to maintain speed boat, the body attitude control is good, in a sprint technology, high frequency high-speed belongs to the steady oars sprint technology, many players using this method for the game of sprint good grades.3. Instant spurt characteristics are, player in a sprint’s last moments, push forward with both feet out, kayak player is on one foot pedal stretch forward, the upper part after quickly fall, boat speed will have a moment of improving, the biggest increase was up to20%, maintain a relatively short time, and grasp the opportunity of the change is key to sprint, the most ideal effect is the maximum velocity to boat just finished the race, but the difficulty is bigger, more reasonable the transient and accelerate technology is player in the boat speed is the rapidly rising process that can be finished the race, the present stage especially short game, the common at home and abroad are instantly accelerated the sprint method, this paper studies total of40people of total31people sprint type, the acceleration of the instantaneous player reached16, accounted for52%of the absolute advantage.4. The basic characteristics of the uniform sprint is in the process of players in the sprint speed boat little change, basic keep in a uniform motion process, including body posture, paddle movement, will not be obvious changes, it is a kind of very stable sprint technology, but not to get good grades. In this paper, the players of the four players used such sprint method, the proportion of small only13%, visible by this method not many players.5. Slow down and slow down the sprint slide two sprint method although exist, but belong to sprint unconventional method, this paper studies in31players only five players in the sprint this method, accounted for16%of the proportion, accounted for52%of the proportion, in addition to35%(11) of the stability of the players attitude sprint method, which includes both the high frequency and high speed OARS basic uniform sprint types, out of the bottom of the cabin, the sprint with less number of the type used, only13%is4players also adopted such sprint method. |
