Consistency of Different Intensity Setting Methods of Aerobic Exercise for Coronary Heart Disease / 中国康复理论与实践

ABSTRACT

@#Objective To explore the consistency of different intensity setting methods of aerobic exercise in order to provide the safe and effective strength setting method for patients with coronary heart disease (CHD).Methods From July, 2016 to July, 2017, CHD patients in our hospital were recruited. The basic data were collected. The patients received cardiopulmonary exercise test firstly to obtain anaerobic threshold, peak oxygen intake and other indicators. They underwent Six-minute Walk Test after a day off. The target heart rate was calculated using anaerobic threshold method (AT), peak oxygen uptake index method (PI), heart rate reserve method (HRR), age estimates method (AE) and quiet heart rate plus 20 method (HR20), respectively. The correlation and consistency of different methods were analyzed.Results There was no correlation (r=-0.131, P>0.05) and there was a very significant difference (P<0.001) between AE and AT on determining target heart rate. There was no correlation (r=0.372, P>0.05) between HR20 and AT. There was correlation (r=0.872, P<0.01) and there was no significant difference (P>0.05) between PI and AT on determining the target heart rate, and the Bland-Altman test showed a consistency between them. There was correlation (r=0.836, P<0.001) and there was no significant difference (P>0.05) between HRR and AT on determining the target heart rate, and Bland-Altman test demonstrated a consistency between them.Conclusion There was no correlation and consistency of AE and HR20 to AT on the target intensity of aerobic exercise. There was significant correlation and consistency between AT and HRR/PI.
