The word "sports" has two meanings: in a narrow sense, it refers to physical education in general; When used in a broad sense, it is the same as what is usually called "exercise", and its meaning refers to the educational process and cultural activities that improve health and quality of life with human movement as the basic means.
The word "health" was put forward by the World Health Organization. "Health is not only the absence of disease and physical weakness, but also the maintenance of good physical, mental and social adaptability."
Therefore, I personally think that the relationship between sports and health is the relationship between means and purpose, that is, sports is the means and health is the purpose.
