Abstract
Background
This study aimed to assess the effect of different types of endurance training during
outpatient cardiac rehabilitation on patients’ health-related quality of life (HRQL).
Methods
The MacNew Heart Disease HRQL questionnaire and the Hospital Anxiety and Depression
Scale were used to assess changes in HRQL in 66 patients before and after 6 weeks
of cardiac rehabilitation. Patients were randomized to 1 of 3 types of supervised
endurance training: continuous endurance training, high-intensity interval training,
and pyramid training. Two-way analysis of variance for repeated measure and chi-square
test were used to analyze changes before and after rehabilitation.
Results
Attendance rate during the 6 weeks of exercise training was 99.2%. Physical work capacity
increased from 136.1 to 165.5 watts (+22.9%; P < .001), and there were no statistical differences between training protocols. Fully
completed questionnaires at both time points were available in 46 patients (73.9%;
61.3±11.6 years, 34 males, 12 females). Regardless of the type of supervised endurance
training, there was significant improvement during rehabilitation in each of the categories
of the MacNew questionnaire (ie, emotion, physical, social, global; all P < .05) and the Hospital Anxiety and Depression Scale (anxiety: P = .05; depression: P = .032), without significant differences between protocols.
Conclusions
All 3 types of endurance training led to significant and well comparable increases
in physical work capacity, which was associated with an increase in HRQL independent
of the type of training. Our findings support further individualization of training
regimes, which could possibly lead to better compliance during life-long home-based
exercise training.
