ABSTRACT
As evidenced by the writings of Hippocrates and Moses Maimonides, it has been recognized since antiquity that incorporation of regular physical activity (PA) into one’s lifestyle, promotes health, well-being, and the quality-and perhaps the length-of one’s life. These observations have been con—rmed by scienti—c evidence accumulated primarily over the past three decades. The evidence is primarily from longitudinal observational studies supported by demonstration of multiple plausible biological mechanisms from animal studies and randomized clinical trials, particularly on the role of PA in the prevention of coronary heart disease (Shiroma and Lee 2010).
