Background High-intensity interval training has recently emerged as superior to continuous endurance training in cardiac rehabilitation upon other training regimes. Individually tailored continuous endurance training and pyramid training could induce comparable effects on peak work capacity as high intensity interval training.
Design A prospective, randomized study.
Methods Effects of the following isocaloric cycle ergometer protocols on peak work capacity have been assessed in patients with coronary artery disease (n=60) during 6 weeks of outpatient cardiac rehabilitation, i.e. 18 supervised sessions of exercise training: (1) continuous endurance training (n=20): 33min at 65-85% peak heart rate; (2) high intensity interval training (n=20): 4x4min intervals at 85-95% peak heart rate, each followed by 3min of active recovery at 60-70% peak heart rate; (3) pyramid training (n=20): 3x8min of stepwise load increase and subsequent decrease from 65-95-65% peak heart rate, supplemented by 2min recovery at 60-70% peak heart rate between pyramids. All protocols were preceded by 5min of warm-up and followed by 5min cool-down at 60-70% peak heart rate.
Results Attendance during exercise sessions was 99.2%. There were significant increases in peak work capacity of comparable magnitude in all three training groups (begin vs. end: continuous endurance training: 136.049.6W vs. 163.4 +/- 60.8W (21.1 +/- 8.5%); high-intensity interval training: 141.0 +/- 60.4W vs. 171.1 +/- 69.8W (22.8 +/- 6.6%); pyramid training: 128.7 +/- 50.6W vs. 158.5 +/- 57.9W (24.8 +/- 10.8%); within groups all p<0.001; between groups, p=not significant).
Conclusion Endurance training protocols assessed in this study all led to significant increases in peak work capacity of comparable magnitude. Our findings suggest that these protocols can be used interchangeably, which will lead to further individualization of exercise prescription and may therefore result in improved adherence to lifelong behavioural changes.
