A Preliminary Study On The Coaches' Experience Risk Of Juvenile Athletes' Sports Fatigue Identification

During sports training,the using of experience to identify sports fatigue is the most commonly method and means of coaches.For a long time,both in China and abroad,experience has brought convenience and efficiency in training,which gradually weaken people's understanding of the risk of experience,and the risk events caused by empirical misjudgement often occur in sports training.Especially,the adolescent athletes,their unique characteristics of adolescent psychological activity and the physiological mechanism of adult athletes need the coaches to use experience to judge sports fatigue carefully,control the limits of experience judgment,so as to avoid the training risk caused by this.Therefore,through questionnaire,literature,experiment,mathematical statistics and analysis,this paper studies and analyzes the coaches' experience in identifying the sports fatigue of young athletes,and sets up a data classification method,which is represented by physiological,biochemical and psychological indicators as a scientific identification of fatigue.According to their research relationship,they form a unity of opposites with experience.The subjects are divided into three groups:1)the subjects of the coaches group:Shaanxi Youth Sports School(hereinafter referred to as:youth sports school),the Shaanxi adolescent track and field management center(hereinafter referred to as the Tian Guan Center),the affiliated secondary school of Northwestern Polytechnical University,the secondary school of Xi'an Jiao Tong University,the Xi'an middle school,and the Shaanxi Normal University Affiliated Middle School,Xi'an rariway middle school,Shaanxi Normal University high level sports team,Baoji sports school,the above 9 units selected 60 coaches with more than 3 years of teaching experience;2)the survey object of the athletes group:from the above 9 units,180 athletes at the age of 13-18 years old,and have More than one year's training experience;3)auxiliary subjects:10 experts in training,senior coaches and national coaches.First,the concept of experience and coach experience is defined,and the related research on sports fatigue of young athletes is discussed,and the relationship between coaches' experience and data recognitionis identified and analyzed.Secondly,through investigation and analysis,we can obtain the channels for the training experience of the coaches,the experience method commonly used to judge the fatigue by experience,and the method of this kind.The degree of understanding of scientific knowledge,the physiological,biochemical and psychological indicators used to judge fatigue,the degree of understanding of the scientific knowledge of the index,the cause of the fatigue misjudgement,the cognition of the fatigue of experience judgment,the cognition of data recognition of fatigue,and the relationship between the two,and so on;and again through the SPSS20.0 statistics software,the analysis of the experiment The physiological and biochemical indexes of the athletes were obtained,and the results were compared with the recognition results before and after the training of the coaches.The difference analysis between the results of the coaches' judgment and the experience of the athletes was obtained.The coaches used the experience to judge the accuracy of fatigue and the use of data recognition to detect and judge fatigue.The difference analysis between the accuracy and the accuracy indicates that the risk caused by the experience judgment fatigue and the data recognition fatigue is significant.Finally,the risk theory and the mathematical model of the sociology and philosophy are introduced,and the risk model of fatigue is established.This paper draws the following conclusions:(1)Experiential methods such as language communication and training subject factors;data recognition method,such as physiological indexes,biochemical indexes and psychological indexes,identify sports fatigue.The coaches have significant differences in the accuracy and understanding of the two types of methods to identify sports fatigue,so the coaches use this kind of method to identify sports fatigue.There is a risk for the coaches to use this kind of method to identify sports fatigue.(2)The experiential method,such as the observation method,the whole and the individual condition of the training,and the field equipment method,there is no significant difference between the coaches to identify the accurate recognition of the sports fatigue and the degree of understanding of the scientific knowledge,but the possibility of the risk is still not excluded.(3)The acquisition of coaches' experience is more suitable for their own training experience accumulation and reflection of teaching process.(4)Coaches' scientific literacy level,teaching level and study frequency affect the accuracy of sports fatigue identification.(5)On the choice of two kinds of methods,coaches tend to choose experiential methods.(6)On the relationship between the two methods,50.56%of coaches feel that the two are not necessarily antagonistic.(7)The model shows that there is no definite boundary between the empirical method and the data method.The coach can synthesize many factors when identifying the athlete's fatigue,and apply the empirical method and the data method dialectically.
