| Research objective:Promoting the development of competitive basketball is one of the important tasks to accelerate the construction of a strong sports country.When the youth is strong,China is strong,and youth basketball players are the root of the development of basketball in China.However,in recent years,China’s youth men’s basketball team has achieved unsatisfactory results in the World Championships,and the world ranking is rapidly declining.Through practical and theoretical analysis and learning from the development experience of strong basketball countries,it can be found that the physical fitness level of basketball players has become a key factor affecting the victory of the game.Although there are a lot of writings on physical training of basketball players by scholars at home and abroad,most of them are"mostly quantitative statistical descriptive data","lack of exploration of in-depth mechanism under the appearance of predicament","not very operable","not very practical".However,most of the studies are limited by "quantitative statistical descriptive data","lack of exploration of in-depth mechanisms under the appearance of difficulties",and "weak operationalization of proposed countermeasures and recommendations",which may be related to the tendency of ignoring the subjective consciousness of athletes participating in physical training.Relevant studies have shown that the psychological tendency of the training subject towards training behavior is a key factor affecting training performance,and the psychological ability of athletes in adolescence has a high degree of instability and strong plasticity.Based on this,this study is different from previous external and macro research perspectives,but takes the physical training performance of outstanding adolescent male basketball players as the entry point,and the scope of the study includes a series of internal and external factors affecting training performance,such as subjective tendency,intrinsic motivation,self-confidence level,and interpersonal relationship,etc.,when athletes are participating in physical training,and quantitatively verifies the functioning mechanism and degree of functioning of the influencing factors,aiming to systematically,scientifically,and comprehensively investigate the psychological tendency of training subjects on training behaviors.The purpose of this study is to systematically,scientifically and comprehensively construct a model of the factors influencing the physical training performance of China’s outstanding young men’s basketball players,with a view to providing valuable sports training science and sports psychology bases for the physical training of China’s young basketball players,and proposing practicable promotional strategies for the improvement of the physical fitness level of young basketball players.Research methods:This study mainly adopts research methods such as literature,expert interviews,questionnaire surveys and mathematical statistics.In addition,in the specific research process,an exploratory time-series mixed method combining qualitative and quantitative research was used to carry out the study,to determine the influencing factors of the physical training performance of excellent adolescent male basketball players and their paths of action,and at the same time,structural equation modeling method was selected to validate the model of influencing factors,and based on the influencing factors,to design a physical training performance promotion program for adolescent basketball players,and to longitudinally intervene by The effect of its practical application is examined.Research results:(1)Adopting and following the coding technique of procedural rooting theory,a total of 51 conceptual categories were obtained by conceptualizing and processing the original statements in the open coding stage;they were sorted into training attitudes,training motivation,training efficacy,training will,professional competence,coaching styles,leadership behaviors,training plans,training contents,training methods,training loads,interpersonal environments,and physical environments in the axial coding stage,information environment,etc.;and in the selective coding stage,it was categorized into four core categories:athlete dimension,coaching dimension,training dimension and environment dimension.(2)Measurement scales created around the 14 categories(latent variables)of training attitudes,professional competence,training programs,and interpersonal environment were tested for reliability and validity,and it was concluded that the scales were suitable for questionnaire testing.Through the structural equation modeling method,the study concluded that the coaches’ dimension with the largest coefficient of influencing factors affecting the physical training performance of China’s outstanding adolescent male basketball players(R2=0.870,P<0.001),and the rest were,in order,the environment dimension(R2=0.862,P<0.001),the training dimension(R2=0.775,P<0.001),and the athletes’ dimension(R2=0.717,P<0.001).(3)After the intervention of the promotion plan,there was a significant difference(P<0.05)in the improvement of the physical training performance scores of the experimental group athletes compared to before the experiment,and a significant difference(P<0.05)compared to the control group.In addition,the experimental group athletes showed significant improvement in scores on various scales in the athlete dimension and environmental dimension compared to the control group and before the experiment(P<0.05).At the same time,after intervention,it was found that the experimental group athletes showed varying degrees of significant improvement(P<0.05)in the 1 minute double jump rope,approach single foot takeoff touch,and sitting forward bending performance compared to before the experiment 3/4 Field acceleration run,1-minute sit ups,15m ×17 turn back running and standing long jump,the test scores of the experimental group and control group athletes showed significant improvement compared to before the experiment(P<0.05).Although the experimental group showed a greater improvement,there was no significant difference between the groups(P>0.05).Research conclusion:(1)The model of influencing factors on physical training performance of China’s outstanding young male basketball players includes four core categories of athlete dimension,coaching dimension,training dimension and environment dimension and 14 categories of training attitude,professional ability,training program and interpersonal environment,etc.The model of influencing factors on physical training performance constructed in this study improves an important theoretical foundation for the improvement of physical fitness level of China’s outstanding young male basketball players.theoretical foundation.(2)In the model of influencing factors on the physical training performance of outstanding young male basketball players in China,there is a significant positive relationship between the athlete dimension and its categories,the coach dimension and its categories,the training dimension and its categories,the environment dimension and its categories,and the physical training performance.It is worth noting that the coaching dimension has the largest influence coefficient in the model,which also indicates the key role of coaches in developing the physical training performance of excellent adolescent male basketball players.(3)The design of the facilitation program based on the influencing factors of physical training performance of outstanding adolescent male basketball players in China can effectively enhance the motivation level,self-efficacy and will quality of adolescent male basketball players to participate in physical training,so as to improve their physical training performance.At the same time,the promotion program also achieved good results in the development of athletes’ physical quality,and the actual application of the training intervention of the promotion program reached the expected goal. |
