Construction And Empirical Research On Evaluation Index System Of Special Physical Fitness Of Chinese Excellent Rock Climbing Athletes

Rock climbing has been officially included in one of the events of the 2020 Tokyo Olympics and has become a household name.Chinese rock climbing has developed rapidly in recent years,and competitive rock climbing has also achieved good results that it is proud of.However,the theory of physical fitness training in China is still in its infancy,especially the research on physical fitness training can no longer meet the needs of the growing climbers in China.This article takes China's outstanding rock climbers as the research object and builds a special physical fitness evaluation index system for China's rock climbers.It aims to supplement the theoretical system of China's rock climbing training and provide references for China's rock climbing training,physical fitness assessment,and athlete selection.The thesis mainly uses literature data method,expert survey method and mathematical statistics method.Among them,the expert survey method collects the opinions of 10 experts on the specific physical fitness indicators through the questionnaire based on the experience and accumulation of experts in the field of teaching and training.Round selection.It has formed a special physical fitness index for China's outstanding rock climbers.The research results are obtained: 1.Established a special physical fitness evaluation index for China's outstanding rock climbers,including three first-level indexes: body shape indexes,physical function indexes and sports quality indexes,10 second-level indexes,fullness indexes,circumference indexes,Length index,cardiopulmonary function index,speed index,strength index,endurance index,sensitivity and coordination index,flexibility index,balance index;14 three-level indicators: BMI,forearm relaxation circumference,arm span,heart rate,30s30 squats,50 Meter running,grip strength,vertical jump,pull-ups,flexion arm hang,10 s standing leg,left and right leg splitting,shoulder rotation,dynamic balance(straight walking).2.According to the questionnaire of rock climbing athletes,calculate the weighting system of rock climbing athletes' specific physical fitness evaluation indicators.The weights of the three first-level indicators are: body shape index 0.33,body function index 0.3,and sports quality index 0.37.Using expert questionnaires to determine the weights,according to the data of excellent athletes in China,the percentile method is used to establish a single physical index scoring standard and a comprehensive evaluation standard for physical fitness.After evaluating the athletes,it can be concluded that:1.The established physical fitness evaluation index system of excellent rock climbers in China,the importance of each index is different,resulting in different weights of each index.2.The physical fitness test results of China's outstanding rock climbers are relatively normal,with individual differences.The analysis result show that Chinese athletes should pay more attention to flexibility and coordination exercises,as well as the overall balance of physical strength development.3.The physical fitness single index score table and physical fitness comprehensive evaluation standard score table of the excellent rock climbers established in China are evaluated by the fifth-grade scoring method,and the evaluation results basically conform to the actual climbing level of the athletes.
