This study reports on the effects of a 3.5 week bicycle ergometer training by the interval method (work and recovery phases each 1:1 min) versus the continuous method. We studied 2 groups of 9 male patients who had undergone a coronary bypass surgery 3-4 weeks ago. Mean maximum training intersity was at 121:20 W (interval training) and at 83 W (continuous training). The interval training resulted in a higher physical performance, lower heart rate, rate-pressure product, and a lower blood lactate level at submaximum work level. Catecholamines were not lowered by the exerecise training. The findings suggest that, after coronary bypass surgery, the interval training is more suited to increase physical performance and is more effective in economizing cardiac work. Verf.-Referat
