Analysis Of The Variation Characteristics Of 500 Meters Speed Of China's Women's Double Kayak During The Preparation Of The 2016 Olympic Games In Rio

Research purpose: Determine the speed variation of woman kayak during preparations for the Olympic Games,to explore changes of speed,compared to before the Olympic Games before the world championships and the speed performance and special training changes,changes in training status and the competitive state of the comparison of the two contest.Research method: The object of study for the Rio Olympics women's doubles,through literature,expert interviews and a preliminary understanding of the special information kayak,tracking test,field observation and record in December 2014 to speed performance of woman kayak during special training and training in August 2016,mathematical statistics,logical analysis,comparative analysis and processing statistics,comparison and analysis of key data.Research results: The women's double kayak 500 meters speed variation by speed into the racing structure obtained in different speed range of the proportion of the changes and the special training changes in World Championships and the Olympic Games before and after the ship.Conclusion:(1)women's double kayak speed is in line with the characteristics of human body for the law.(2)according to the speed and speed process should be divided into 4 stages and 3 speed inflection point.(3)preparing for the Olympic Games and World Championship Women's kayak speed changes during an obvious difference between the maximum speed and acceleration performance,performance is not stable,the way is rhythm instability before the rhythm changes.(4)the main speed range of 500 meters for the women's double sculls 4.5-4.9m/s,occupies more than 50% of the proportion of distance.(5)the proportion of aerobic training in the whole preparation process is the most part of the total amount of training,the overall training intensity is low,and the training is higher.(6)the athlete's speed ability is very important for the improvement of athletic performance.(7)the anaerobic capacity is related to the maximum speed,the upper limit of the average velocity of the whole population,and the breakthrough of the achievements.Aerobic capacity is related to the speed change trend,speed can slow down the rate of decline,the lower half of the speed and strength.(8)the maximum speed is 500 meters or 80% kayak racing training and anaerobic capability has an important critical oxygen training.
