The prevalence of many chronic diseases increases markedly with advancing age. With an ever increasing aging population accompanied by steadily rising costs of medical care, prevention and treatment for age-related chronic diseases has become an extremely important topic, especially for those older adults who may be retired or are living on a fixed income. The first-line approach for preventing and treating age-related chronic diseases is increases in physical activity [1,2]. Although regular exercise does not appear to extend longevity [3], there is substantial evidence demonstrating that regular physical activity decreases the risk of premature death [1,2,4]. Over the years, habitual exercise has become the biggest patron for the famous quote of Benjamin Franklin “An ounce of prevention is worth a pound of cure”.
