ABSTRACT
Objectives: This study aim was to compare the impacts of high intensity interval (HII) to moderate intensity continuous exercise (MIC) on ventilatory markers in patients with coronary heart disease (CHD).
Design: Twenty eight patients with mild to moderate CHD aged 50-60 years were selected for this study. They randomized to two groups, each group comprised of 14 patients, group I received a program of high intensity interval exercise (HII 3 times/week for 12 weeks) and group II received a program of moderate intensity continuous aerobic exercise (MIC 3 times/week for 12 weeks). The ventilatory marker changes (O2P, slope of VE/VCO2 and OUES) have been measured at the beginning and the end of the study.
Result: After 12 weeks of enrollment, HII group showed statistically significant improvement in O2P but no significant changes in MIC group (21% with p<0.05 versus 1% with p>0.05). No significant differences appeared in VE/VCO2 and OUES (pre- and post- program) in the two groups p>0.05.
Conclusions: It was concluded that HII had greater improvements than MIC on ventilatory markers in patients with CHD in a short term (up to twelve weeks).
Key words: Coronary Heart Disease, High Intensity Interval Exercise, Moderate Intensity Continuous Exercise, Ventilatory Markers.
