چکیده مقاله:
Background: High-intensity interval training is a new training method that has been less explored in patients.
Aim: The purpose of this study was to compare the effect of eight weeks of interval training with continuous training on changes in HRR and lipid profile in cardiac patients post-coronary artery bypass graft.
Methods: In this clinical study, 30 cardiac patients of Tehran Heart Centerthat hadundergone CABG surgery were randomly divided into two groups, interval and continuous training. The protocols included 4rep × 4 min at 90-95% for interval group, and 60-80 minutes at 70-85% peak HR for continuous group. HRmax, HRR at 1, 2 and 3 min following Bruce test was assessed before and after the training program. The collected data were analyzed using SPSS software version 16 and ANOVA test (p<0.05).
Results: HRR at 1 & 2 minute was reduced more in both interval and continuous groups than that of before the training program (p<0.05). The HHR reduction at 1&2 minutes was more significant in the interval group than the continuous group after exercise stress test (p<0.05). The changes in HRR at 3 min in both groups were not significant compared to that of before the training program (p=0.1).
Conclusion: Both high-intensity interval training and moderate-intensity continuous training improve HRR and lipid profile in cardiac patients after coronary artery bypass. Interval training is more effective on HHR reduction than continuous training.
