Background: Physical activity is known to increase average life expectancy and decrease the risk of development and progression of most chronic degenerative disease states. Strenuous physical activities are found to be associated with a reduced risk of coronary heart disease (CHD) and a significant improvement in glucose control and insulin sensitivity while physical activities of lower intensities were not. However, strenuous exercise was found to increase bone resorption, without a concomitant increase in formation in young adults rendering the bone vulnerable to fracture but there is lack of data supporting these findings among healthy aged population.
