Abstract. A daily routine of physical activity is highly beneficial in the prevention and treatment of many prevalent chronic diseases, especially of the cardiovascular (CV) system. However, chronic, excessive sustained endurance exercise may cause adverse structural remodeling of the heart and large arteries. An evolving body of data indicates

The health benefits of exercise have been recognized since the epidemiological studies of Morris et al. , who in the 1950s reported lower rates of coronary heart disease among the conductors of London's double-decker buses compared with the drivers.Morris et al. also reported a lower incidence of coronary heart disease among English postmen compared with

Pro@Heart's older cohort, the retired rowers, has a startling rate of AF: 20%, compared with 3% in the control group. Elite rowers may have a higher AF risk than some other endurance athletes—perhaps because the sport attracts taller people. Height is a documented AF risk factor, though the reasons are still being explored.
