2.2 The relationship between sports and physical strength
There is a close relationship between sports and physical strength. Saltin and Pilegaard (2002) from Denmark point out that
regular sports can boost the health condition of muscle metabolism and there are significant impacts on the prevention
from diseases. Working out for three times a week also can enhance the metabolism function of muscles and postpone the
happening chance of chronic disease. Even doing low-strength sports is beneficial to muscle health improvement (Chang,
Ru-Je, 2002).
2.3 The relationship between sports, health and disease
Regarding to the benefits of physical activities on prevention of cardiovascular diseases, plenty of researches are done
abroad and the results all point out that physical activities can avoid the happening of cardiovascular disease. The
proportion of sedentary people who die of cardiovascular disease is 1.5 or 2 times higher than that of people who do
middle-strength sports (Centers for Disease Control and prevention, 1996). Besides, some other studies indicate that
people who have a sedentary or low-level of physical activities lifestyle, once they carry out moderate physical activities,
there will be a great help to prevent from cardiovascular diseases.

From the above-mentioned information, there is an inseparable relationship among sports, healthy physical conditions
and cardiovascular diseases.
