China has entered a new phase of constructing a peaceful communist society, and the role of sports is also evolving. Sports are becoming increasingly integrated into daily life. This study examines the significance of Marx's theory of psychological identification in enhancing sports performance. The articles are sorted using the literature approach and the mathematical statistics method, and an empirical examination of the status of Marxism belief in sports universities is undertaken. This research examines the influence of psychological identity intervention on athletes' Marxist theory beliefs and sports performance using two athletes as volunteers. The results indicate that the two athletes' level of psychological identification with Marxian theory beliefs has increased. The dimensions of observation, non-evaluation, and non-response are enhanced, while the dimensions of description and conscious performance remain relatively unchanged. Athletes' self-evaluations also verify the intervention's effectiveness. It is determined that enhancing the education of Marxist views in sports student groups is a major component of the civic education of college sports students, which is intimately tied to the development of the national socialist cause and the nation's future.

Polymorphisms of the ACTN3 and ACE genes related to athletic performance are controversial due to those who favor differences between ethnicity and athletic status. However, although the above is the subject of debate through genetics, it is known that the potential benefits of the R + I allele fall on anaerobic performance and the carriers of the X + D allele on aerobic performance, biologically indicative that the genotype RX + DD + II is the key to the excellent performance of athletes with similar physical abilities and makes both power and endurance phenotypes important. The objective of this paper was to select and describe the studies that support the association of the genotype of the ACTN3 and ACE genes with the performance of individual sports athletes, considered elite for their high sports performance. 1,153 articles on the subject were reviewed and only 13 were included in the research. The results obtained indicate that athletes with the RR/RX + ID/DD genotype stand out in speed/power and those with the XX + II genotype in endurance. In conclusion, it is possible that there is a specific genetic structure associated with the polymorphisms of the ACTN3 and ACE genes that allow them to be predisposed to a high level of anaerobic and/or aerobic performance.

In this paper, a Network DEA approach to assess the efficiency of NBA teams is proposed and compared with a black-box (i.e. single-process) DEA approach. Both approaches use a Slack-Based Measure of efficiency (SBM) to evaluate the potential reduction of inputs consumed (team budget) and outputs produced (games won by the team). The study considers the distribution of the budget between first-team players and the rest of the payroll. The proposed network DEA approach consists of five stages, which evaluate the performance of first-team and bench-team players, the offensive and defensive systems and the ability for transforming the points made by itself and by the opponents into wins. It has been applied to the 30 NBA teams for the regular season 2009-2010. The results show that network DEA has more discriminating power and provides more insight than the conventional DEA approach.
