Abstract:
Objective:To investigate effects of high-intensity interval training(HIIT)and moderate-intensity continuous training(MICT)on cardiorespiratory function,aerobic capacity,cardiac autonomic function,cardiovascular risk factors,and quality of life in patients with coronary heart disease.Method:Forty-six patients with coronary heart disease were selected and randomly divided into 23 cases in the HIIT group and 23 cases in the MICT group.The cardiac function indexes[left ventricular end-diastolic volume(LVEDV),left ventricular ejection fraction(LVEF),and stroke volume(SV)],pulmonary function in-dexes[maximal voluntary ventilation(MVV),maximal expiratory flow(PEF),and maximal expiratory pressure(MEP)],and aerobic exercise capacity indexes[peak oxygen uptake(PeakVO2),anaerobic threshold(AT),peak oxygen pulse(VO2/HR),six-minute walking distance(6MWD)],cardiac autonomic function indices[heart rate recovery(HRR-1 min),peak heart rate,resting heart rate],cardiovascular risk factor indices[body mass index(BMI),resting systolic blood pressure,resting diastolic blood pressure],and quality of life indices(selected dimensions of SF-36).Result:After training,the levels of LVEDV,LVEF,and SV were higher in the HIIT group than in the MICT group(P<0.05).After training,the levels of MVV,PEF,and MEP were higher in the HIIT group than in the MICT group(P<0.05).After training,the levels of PeakVO2,AT,VO2/HR and 6MWD were high-er in the HIIT group than in the MICT group(P<0.05).After training,HRR-1 min and peak heart rate were higher in the HIIT group than in the MICT group(P<0.05).After training,the BMI,resting systolic blood pressure,and resting diastolic blood pressure levels in the MICT group were lower than those in the HIIT group(P<0.05).After training,the SF-36 scale scores of physical function,vitality,and health transition in the HIIT group were higher than those of the MICT group(P<0.05).Conclusion:Both HIIT and MICT can effectively improve cardiopulmonary function,aerobic exercise capaci-ty,cardiac autonomic function,cardiovascular risk factors,and quality of life in patients with coronary heart disease.HIIT demonstrated superior effects in improving cardiopulmonary function,aerobic exercise capacity,cardiac autonomic function,and quality of life in patients with coronary heart disease,while MICT is more ef-fective in improving cardiovascular risk factors.
