To realize the recognition and scoring of Wushu Athletes’ wrong actions by electronic referees, reduce the difficulty of referees’ recognition, help reduce man-made errors and influence in the process of competition judgment, and make the referee work fairer and more scientific, therefore, this paper aims to make an in-depth study on the Wushu refe...

... Wushu sports have a long history and have been continuously refined and perfected under the development of generations of wushu practitioners especially the research on wushu sports has become more in-depth after entering the modern society, which has provided strong support for the development of wushu sports science [1]. As an important theoretical basis of sports, sports biomechanics has been gradually applied to wushu sports to study the principles of force generation and movement techniques and to lay the foundation for the improvement and innovation of wushu sports [2][3]. ...
Combining the athletes’ wushu jumping action data from the perspective of sports biomechanics, forming a finite element model based on finite element analysis of the landing speed of wushu jumping action on the landing stability correction finite element model, solving the different heights, can not be difficult to land the PvGRF of the wushu action, the use of kinematics sensitive indexes to diagnose the difficulty of competitive wushu sets of action. Measure the movement data of wushu athletes’ spinning foot 720° catching horse stance movement, and analyze the swing changes and rotational angular velocities of various body segments in the assisted jumping phase and the aerial movement phase. A core stability training method was proposed and tested during a 12-week training period, and an index test of balance was conducted. The results of the balance index test of the wushu athletes showed that after the core stability training, the static right foot standing index was 179.55±196.35, which formed a significant difference with the pre-training period, P<0.05. The combination of core stability and sports biomechanics can improve the completion of difficult movements in the movement training of competitive wushu athletes.
Introduction: During the last decade, it has become evident that the impact of a referee's decision in professional sports turns out to be a turning point in the outcome of a competition, often generating discomfort among fans and competitors. It is for this reason that technological assistants were implemented in sports to help in referee decision making.Objective: Review and analyze those technological solutions based on the use of artificial intelligence techniques capable of serving as technological assistants in support of referee decision-making in highly competitive professional sports.Method: The PICO methodology was used for the selection process of scientific publications of the PRISMA declaration. Finding 21 scientific publications extracted from the SCOPUS database that comply with the proposed guidelines, which were reviewed and analyzed to obtain information with added value.Results: It was found that the proposed technological assistants reached a level of precision greater than 90% in certain sports. Likewise, those limitations were found that reduce the operational quality of these solutions. As found those algorithms, models, methods and approaches of artificial intelligence most used and recommended for future research studies.Conclusions: In conclusion, the implementation of technological assistants based on artificial intelligence in referee decision making in professional sports has proven to be an effective tool, achieving significant levels of precision.
