Analysis And Application On The Two Arm Stroke-ventilation Technique On National Excellent Female 200 Meter Butterfly Athlete

Ventilation technique is the basic and key technique of butterfly stroke,the rationality of the technology plays an important role in other actions,but it is a pity that,ventilation technology is just a neglected and neglected technology in theoretical research,what kind of ventilation technique does the world elite women's 200 meter butterfly perform during the race?,How about the technical features?,What are worthy of reference and promotion?,There is still a lack of systematic research.This research takes domestic outstanding female 200 meter butterfly athletes Jiao Liuyang and Liu Zige as examples,using literature,expert interviews,questionnaires,mathematical statistics and logical analysis and other research methods,in combination with their performance in the world series,the use of the two arm ventilation technique was analyzed,this paper summarizes the present situation and characteristics of the two arm ventilation technique used by elite Chinese women's 200 meter butterfly players in the competition,The factors influencing the two arm ventilation technique were summarized and the countermeasures were put forward.Through the study,the following basic conclusions are obtained:1.The world's elite women's 200 meter butterfly athletes in the game of arm ventilation technology has a common characteristic,mainly a stroke arm once suction,again stroke arm does not inhale,but there are significant differences.2.The same arm ventilation technology,Jiao Liu Yangtu in the middle reaches of the whole,namely two strokes a breathing arm(two arm ventilation technology);Liu Zige is a stroke a breath and then add two strokes a breath,which is also a product plan the arm ventilation technology.3.The two body position will not arm ventilation technology is very high,not only helps to reduce the process of forward movements,can effectively keep the body balance,and energy saving,high efficiency;and the completion of the second athletes in the stroke will be more relaxed,helps to better save energy.4.Because the two arm ventilation time and breath easily lead to acidic substances and causes muscle fatigue,weakness is the two arm butterfly ventilation technology.5.Butterfly two arm ventilation technology constraints include the action cycle and breathing coordination rhythm,ventilation body height angle and ventilation timing three aspects.
