Research And Implementation Of Exercise Prescription Subsystem In Competitive Sports Big Data Platform

The continuous progress of sports has promoted China to achieve more honors in competitive sports.However,there are also many problems,it is difficult to make full use of training data,traditional recording methods are used,and human factors lead to errors.The advent of the era of big data has enhanced people’s ability to collect,store and analyze,promoted the further integration of sports and the Internet,and established a competitive sports big data platform for collecting and analyzing data,collating and summarizing relevant experience and technologies in the field of competitive sports,and building an expert system combined with sports prescription knowledge,so as to help athletes.In this paper,the expert system is mainly responsible for the recommendation and adjustment optimization of exercise prescriptions,including data input and storage,knowledge base construction,and inference machine establishment.Data input and storage provide data support for expert systems for reasoning and analysis;Knowledge base construction includes the construction of motion ontology and movement rules,and the knowledge base is the core content of the expert system;The inference machine supports ontology reasoning and adopts the Jena rule language.This paper designs and implements the exercise prescription subsystem in the competitive sports big data platform.Firstly,the background of the big data era is analyzed,and the relevant technologies of sports prescription and expert system are introduced in combination with the requirements of competitive sports.Combined with the requirements of Party A,the role analysis and use case analysis were carried out,so as to determine the functional requirements contained in the system;Through system profiling to determine the overall architecture of the system,specific functional modules are divided,including data management module,personnel management module,exercise prescription module,and then interface design and database design are carried out;The class diagram and functional timing diagram of each module of the system were determined,coded and implemented according to the detailed design,and the motion prescription subsystem was realized,and the interface was displayed;Finally,the system test is carried out,and the vulnerabilities and problems of the system are improved,and the functional and nonfunctional requirements of the system are met.The overall design and implementation of the exercise prescription subsystem has been completed,and the first version of this paper has been used online at Beijing Sport University.The system as a whole meets the needs of users and can be carried out normally in daily training.
