The difference between low and moderate intense resistance training, combined with aerobic endurance training, on exercise tolerance and functional capacity in patients with heart failure

Abstract

Objectives: This pilot study will clarify which intensity of resistance training, combined with aerobic endurance training, will maximize the effects of aerobic endurance training in patients with HF. Participants: Patients with HF who rehabilitated in ‘Ziekenhuis Oost-Limburg, Genk’ were included in the study. Seven participants, randomized into two intervention groups, completed at least 80% of the 20-session training intervention. Measurements: The primary and secondary outcomes are the measurements of the six minute walk test (6MWT), cardiopulmonary exercise test (CPET), blood pressure (BP) and heart rate (HR). At baseline, a descriptive questionnaire, the Minnesota Living with Heart Failure Questionnaire (MLwHF) and a one-repetition maximum (1RM) test were executed. Results: A significant positive trend is seen for VO2 peak in the moderate intensity training group. No significant differences were found for the 6MWT, HR, BP and other parameters of the CPET. Conclusion: Combined with aerobic endurance training, moderate intensity resistance training tends to be superior to low intensity resistance training to maximize the effects of aerobic endurance training in patients with HF. Further research, with larger sample sizes, longer training intervention and/or longer follow-up period, is necessary to optimize the intensity of resistance training, when combined with aerobic endurance training.
