چکیده
period; Vo5 max = maximal oxygen consumption T he cardiac profile of individuals who participate regularly in vigorous, isotonic exercise is characterized by left ventricular (LV) volume overload with increased LV internal dimension, LV end-diastolic volume, stroke volume, and LV myocardial mass.”4 Such adaptations are commonly reported in highly trained endurance athletes, especially runners.5 Because running is associated with a significant number of musculoskeletal and orthopedic injuries,6 distance walking is increasingly prescribed to promote health and TM To clarify the cardiovascular adaptive changes to long-distance high-speed walking, we studied the cardiac dimensions, systolic time intervals, and aerobic capacity of national-caliber race walkers and compared them with those ofcontrol subjects and other endurance athletes of similar age.
