[ Acute cardiovascular and metabolic changes in interval and endurance training in selected patients following aortocoronary bypass operation ] . UNLABELLED This study compared the acute changes of cardiovascular and metabolic reactions during interval and continuous training after coronary bypass surgery . Two groups of 9 male patients ( age : 59 +/- 4 and 56 +/- 6 years , resp . ) each trained on bicycle ergometer start on post-operative days 24 and 26 , resp . In both training groups training heart rate was set at 86 % of individual maximum heart rate . In the last week of training the exercise intensity in the group of patients who were trained by the continuous method was at 83 watts , and at 20:121 watts in the group of patients who were trained by interval method ( rest : work each 1:1 min ) . At this exercise training that lasted for 20 min the acute response of heart rate , blood pressure , rate-pressure product , glucose , lactate and catecholamines was measured . RESULTS In both methods there were no significant differences in systolic and diastolic pressure , rate-pressure product , in glucose or catecholamine levels . However , there was a significantly higher rate of lactate in the second 10 min of the interval training . And , in spite of higher peripheral exercise intensity by interval training , there was no higher cardiac work than by the continuous training . These findings suggest that interval training strains the oxidative capacity of the trained muscles in a more intensive and direct way than does continuous training .
