RETRACTED: The value of physical education to the physical and mental health development of left-behind children from the perspective of health dividend

Abstract

Nowadays, due to the rapid development of social economy, many rural labors have flowed into more developed cities, resulting in more and more left-behind children(LBC), which is an urgent problem in our country's life. Although there are many researches on LBC, there are few researches on LBC's physical and mental health(PMH).In this regard, this paper studies whether physical education and exercise are very important for improving PMH in LBC, and collects and classifies data on PMH in LBC by referring to the literature. Interviews are used to collect the true thoughts of LBC and to understand PMH. The questionnaire survey was used to investigate the PMH status of LBC, and objectively and comprehensively collected the PMH status data of LBC. Finally, the data obtained are statistically analyzed by the method of several examples. This paper studies the situation of LBC participating in extracurricular sports activities and makes a comparison with non-LBC. The results show that the LBC who take part in more after-school sports training have better PMH, more cheerful personality, more love and compassion, can quickly adapt to a new environment, and are emotionally stable. They can handle things calmly and develop their individual emotions well. In addition, the probability of PMH problems of non-LBC is smaller than that of LBC. Through the research and analysis of sports and PMH of LBC, it is found that sports play a positive role in promoting the PMH of LBC. Therefore, physical education is of great value to promote the healthy development of LBC.
