Tactical analysis in football has rarely been conducted using a mathematical model with numerical data (although tactical analysis through objective data has been used more often). Therefore, this study establishes principles for tactical analysis in team sports using numerical data, through a mathematical model based on the location of the players and the ball. A competitive match between Sanfrecce Hiroshima (home) and Ehime FC (away) in the third round of the Japanese Emperor’s Cup 2011 was filmed and used for the match analysis. Observations were made by a team analyst as well as extracted from official match records. The main procedure in the research flow was to establish a mathematical offence/defence model based on tactical concepts in football, which was applied for the location of players, which, in turn, was quantified from video images in order to categorise a team’s tactical performance (in relation to attacking or defending). Furthermore, the authors focused on attacking categories and identified different types of passes during a specific period, as well as comparing these findings with an actual match video. The results obtained from the numerical data derived from applying the offence/defence model led to the same overview as the tactical analysis produced by a team analyst. In addition, the results when categorising types of passes (as extracted through the mathematical model) again mirrored those retrieved from an actual match video. This leads to the conclusion that the offence/defence model could provide relevant insight into types of attacks. The data revealed that football tactical analysis can be successfully performed using a numerical model, which might possibly enable automatic tactical analysis of football games without a match analyst.

In this fast-developing era of the 21st century, the spread of culture is far beyond people’s imagination. Since it was introduced into China, Latin dance has developed rapidly and now entered colleges and universities as a novel major. The focus of the education of Latin dance has gradually turned from popularization to cultivating specialized Latin dancer. Professional physical colleges and dance schools have also established art departments or dance departments one after another to ensure more students to obtain corresponding qualifications through theoretical and practical learning professionally and systematically, and pursue the artistic temperament and enthusiasm brought by dance. However, in the development process of modern Latin dance in China, there are some defects in universities’ Latin dance courses. It is especially important to understand the importance of body posture in Latin dance. This paper introduces the requirements of five kinds of Latin dances on body posture. By using the methods of literature, induction and analysis, interview and investigation, combined with the characteristics of Latin dance, this paper explores and analyzes body posture in Latin dance and its important significance. Then the practice methods of body posture in Latin dance and its influence on Latin dance practice in the future are obtained.

In recent years, under the reform of new curriculum education and teaching in China, students’ learning pressure in cultural courses is getting bigger and bigger, especially in senior high schools. Due to the increasing learning pressure of cultural courses, students’ physical fitness is neglected in education, which makes students’ physical fitness decline, thus directly affecting the learning state of senior high school students. Therefore, in the education of senior high school students, attention should be paid to physical education methods, students’ lifelong sports awareness should be cultivated, and the quality of physical education methods should be enhanced so that students’ physical fitness can be improved and their full physical and mental state can be put into study.
