Research on the Artificial Intelligence Attribution Analysis and the Reasons for Decline of Physical Fitness of College Students in the Tropical Area under the Background of "Sunshine Sports"

. In 2010, the research team conducted a survey on the physical quality of 1600 college students in Hainan Province, and analyzed the changes in the physical quality of college students in Hainan from 2000 to 2010, and learned about the impact of sunshine sports on the physical quality of college students in Hainan Province. Based on this, a targeted intervention was proposed, which can provide reference for the sports workers and decision-makers in Hainan Province and improve the physical quality of students.

"Sunshine Sports" is an important part of school sports. It is an important measure to enhance students' physical fitness, mental health, and overall development of school sports. Physical fitness is a comprehensive reflection of the functions of various organ systems in the muscle work.

Therefore, the study on the effectiveness of sunshine sports on the improvement of college students' physique health level has important practical significance for improving the physique health level of college students and cultivating more outstanding talents and the realization of "Chinese dream" for the socialist modernization of the motherland.
1 Research objects and methods

Research objects
Select Hainan Province students' physical fitness research points 1600 students aged 19~22 of Hainan Normal University, 100 males, males, urban women and females in each age group.

Research methods
Investigation method: According to the requirements of the "National Student Physical Health Survey and Research Rules", organize professionals to measure the 50 m running, standing long jump, grip strength, sitting body flexion and endurance quality of each subject and other 5 physical qualities. Mathematical statistics method: statistical analysis of the data obtained by the survey using software such as SPSS18.0 and Excel 2003, which are widely used in the international social science statistical software. It can be seen from Table 1 that the average value of 50m running in rural boys is less than the mean of urban boys. After U test, the difference of 21 years old is significant (P<0.05), and the difference of other age groups is not significant (P<0.05). The average value of urban girls and rural girls is 50 meters, the difference of 19 years old was significant (P<0.05), the difference of 22 years old was highly significant (P>0.01), and the difference of other age groups was not significant (P>0.05). It can be seen from Table 2. In terms of standing long jump indicators, the average value of urban boys is smaller than that of rural boys, and the performance of males is better than that of urban males. After U test, the difference of 21 years old is significant (P<0.05). 22 years old was highly significant (P<0.01), and the difference between the 19 and 20 age groups was not significant (P>0.05).As far as the grip index is concerned, the average value of urban boys is higher than that of rural boys. According to U test, the difference of 19 years old is highly significant (P<0.01), and the urban-rural difference of 20-22 years is not significant (P>0.05). It can be seen from Table 3 that the average value of urban male students running 1000 meters is higher than that of rural male students. The results of rural male students are better than urban male students. According to the U test, except for the urban-rural difference of 20 years old, the difference between urban and rural areas is highly significant (P<0.01). The age group was not significant (P>0.05). The average value of urban girls' 800-meter running is lower than that of rural boys. Urban girls' cities are better than rural girls. According to U-test, except for the 19-year-old urban-rural difference (P<0.01), the other age groups are not significant (P>0.05). As shown in Table 4, the average value of urban boys is lower than that of rural boys. According to the U test, except for the difference between urban and rural areas of 21 years old, the difference between urban and rural areas is highly significant (P<0.01), and the urban-rural differences of other age groups are not significant (P> 0.05). The average value of rural girls is higher than that of urban girls. According to the U test, the differences between the 19-22 age groups are not significant (P>0.05). Through the development trend of Hainan college students' physical fitness from 2000 to 2010, it can be seen that the male students' 50-meter performance has decreased year by year, male and female college students have set a long-term decline in the first five years. The annual increase, and the increase of female students is more obvious; the male and female grip strength indicators are increasing year by year, the male students' 1000 meters index is decreasing year by year, but the decline in the next five years is lower than the previous five years, girls The 800-meter indicator rose five years after the decline in the previous five years; the male seated flexion index fell five years after the five-year increase, and the female student increased year by year, but the increase in the next five years was significantly less than the previous five years.

Comparative analysis of the physical quality indicators of college students in Hainan Province and similar indicators in 2005 and 2000
3 Intervention strategies and conclusions 3.1 Intervention strategy 3.1.1 In implementing the spirit of the document, all colleges and universities should seek truth from facts and adapt to local conditions. According to the actual situation faced in their own school sports work, they should do a good job in physical education classroom teaching.
