Long-distance Freestyle Athletes In The World Of Good Pace Characteristics Analysis

Analysis the relevant achievements through video observation, mathematical statistics and comparative analysis methods on the2011World Swimming Championships, the2012Olympic Games and the2013World Swimming Championships in the400meter freestyle,800meter freestyle and the1500meter freestyle final athletes.Aiming to reveal the world elite long distance Freestyle Swimmer in the world competition in the pace, hoping to provide some theoretical reference for the future training and competition, and help to improve the overall level of swimming.The results show that:1. There are3methods about speed with middle distance and long distance Freestyle Swimmer:deceleration, even pace and acceleration.2. Studies show that the outstanding400meter freestyle athletes tend to swim by even pace. Male athletes sectional speed are faster than female athletes, and final sprint and speed keeping abilityis better than that of female athletes.3. Studies show that, male athletes speed tend to accelerate tour, way to swim segment time decreased. Women athletes speed tends to slow travel, the way travel segment time is on the rise.4. The research indicates that, the male athletes speed tends to accelerate the swim, way to swim segment time decreased. Women tend to swim deceleration. The world’s elite athletes segmentation performance fluctuation is small, the different level of training leads to the final result of different players usethe same way to obtain different pace.5. Different players in the same game as well as the same of athletes in different race pace has a certain similarity.
