Isolated perfused working hearts of 25-mo-old male Sprague-Dawley rats trained to run for 16 wk were compared with hearts from 9- and 25-mo-old sedentary animals. Under low work load conditions, systolic and diastolic aortic pressures, aortic flow, and oxygen consumption of the three groups were similar. Under high work load, systolic pressure of trained old and 9-mo groups were higher than the 25-mo sedentary values, but diastolic pressures were similar. At a systolic pressure of 150 mmHg… CONTINUE READING
