Research On Physical Fitness And Assessment System Building Of Chineses Elite Female Kumite Athletes

In this study,literature methods,questionnaire survey methods,and test methods were used to analyze the physical characteristics of kumite athletes of the elite women's karate team in China.In addition,based on the original measurement data of elite athletes' physical fitness indicators,the evaluation system of physical fitness of elite female athletes in China has been established,which provides a theoretical reference for athletes' physical fitness training and evaluation.The main conclusions of this study are as follows:1.Physical fitness refers to the ability of athletes to bear the load and adapt to the environment while performing group exercises.It is a comprehensive manifestation of the specialization of physical form,physiological function and athletic quality.It is obviously different from other items,and it is decided that the athletes The key part of competitive ability and athletic performance.The rhythm of the hand of the team has obvious intermittent characteristics,and the technical movements are characterized by rapidness,control,accuracy and diversity.2.The body shape of the hand athletes of the elite women's karate team in China is mainly characterized by the length of the upper limbs,the width of the shoulders,the tight surrounding of the upper arms,the low percentage of body fat,and the weight of the lean body.The lean body mass index increases with the increase of the body weight level.Physiological function is characterized by strong anaerobic and aerobic metabolism,high hormone levels,and strong body resilience;athletic performance is characterized by special rapid strength,special sensitive coordination ability,and special strength endurance.It also has good starting speed and braking.Competence,with the increase of body weight,special sensitivity coordination and speed endurance are diminishing.3.This study constructed a physical fitness evaluation system for elite athletes of Chinese women's karate team.The structure includes three parts: evaluation indicators,index weights,and evaluation criteria.The evaluation indicators include three first-level indicators,10 second-level indicators,and 10 third-level indicators including form,function,and quality.Among them,the sports quality occupies the largest weight,followed by the physiological function and body shape,and the evaluation criteria are divided into scores.Evaluation criteria and rating criteria.4.The physical fitness evaluation system constructed in this study can reflect the common problems in the overall physical development level of the overall excellent group;at the same time,the evaluation system can specifically diagnose the individual athletes' strengths and weaknesses in physical fitness development.
