A Study Of Chinese Native Plateau Race Walking Athlete Selection--Analysis Of Body Shape Index

In order to better promote the sustainable and healthy development of the Race project, the plateau race walking athletes has been outstanding performance in the world competitions. This paper studied the body shape index of our country’s race walking teenagers athletes. Using the literature material method, investigation research method, test method and mathematical statistics method, studied the body shape test index of the first eight race walking athletes who join the first and second session of track and field endurance project match play in plateau area.Research conclusions are as follows:1) Through screening the test index of the plateau race walking athletes, found that height, sitting height, lower limb length, leg length plus feet higher etc; shoulder width, hip width, ankle width, knee girth etc; muscle, the content of protein, fat percentage, fat control, weight control, muscle control, intracellular fluid, extracellular fluid and so on, reflect the athletes’ physical composition and body symmetry degree index, have a high correlation with the teenagers race walking athletes’ special scores.2) The development peak of the teenagers race walking athletes of our country is as follow:women is12to13years old, male is12to15years old. Female athletes’ body fat percentage is higher than the same age male athletes;Teenagers body relatively light, too much fat, weight and muscle content will affect the competitive level of play;intracellular fluid, extracellular fluid and body shape index, have certain influence on the special scores.3) Through the factor analysis, obtained athletes’ body shape characteristic index and weight of the different gender and selection stage including the primary stage, the key selection stage and selection stage.4) Set up the plateau race walking project selection stage of different gender athletes’ body shape characteristic index single rating scale of our country. Primary, key selection, optimization phase of single rating standard has the difference, which is mainly manifested in the body shape characteristics of different indicators, the same body shape characteristic index score standard interval is different.5) Primary stage, our plateau woman race walking athletes’fruit weight/height x1000index is lower than plain excellent race walkers. Key selection stage, our country our plateau race walker development faster, has basically to achieve outstanding race athlete’s body shape index range. Optimization phase athletes height index has reached good race-walkers range value, athletes weight is lighter, leg length plus feet high value is opposite bigger.6)According to each single index for different age groups and gender athletes’ physical form of contribution, in establishing a China plateau teenagers race walking athletes’ body form comprehensive grade evaluation standard.7)Through the back and inspection, do the accuracy test for the established teenagers race walking athletes’ body shape grade evaluation criteria.Results show that get top eight athletes’ physical form comprehensive score are basic located in medium to high and fine grades, the establishment of comprehensive rating score standard can be used as our country plateau teenagers race walking athletes’ different selection stages’body shape evaluation and selection of reference.
