Επιδράσεις διαφορετικών προγραμμάτων άσκησης σε ασθενείς με χρόνια καρδιακή ανεπάρκεια

Profiling the effects of different exercise modalities in patients with chronic heart failure
Summary:
Background: Aerobic exercise, either continuous or high intensity interval training (HIIT),
induces important benefits in chronic heart failure (CHF) patients. Resistance training has
been also shown to be beneficial in CHF. However, data regarding combined aerobic exercise and muscle strength training is still limited. The aim of this study was to investigate whether adding strength training to a HIIT protocol within a cardiac rehabilitation (CR) program has a cumulative beneficial effect on the functional capacity (FC) and quality of life (QoL) in patients with CHF. Methods: Forty-four consecutive patients [35 males, ejection fraction (EF) <50%] with CHF under medication enrolled in a 36-session CR program and were randomized in two exercise groups; HIIT (HIIT group) or HIIT combined with strength training (COM group). All patients underwent baseline and endpoint outcome measures of a symptom-limited maximal cardiopulmonary exercise testing (CPET), 1 repetition maximum (1RM) test, muscular endurance test, echocardiography, and Minnesota Living with Heart Failure Questionnaire
(MLWHFQ).
Results: Most of the CPET indices, EF, 1RM test, muscular endurance and QoL were
improved after the CR program in each exercise training group (p < 0.05). However, COM
group demonstrated a further improvement in chest muscle testing and workload at anaerobic threshold (AT) compared to HIIT group.
Conclusions: A CR program, consisted of either HIIT or HIIT combined with strength
training, improves FC and QoL of patients with CHF. However, the addition of strength
training to HIIT seems to have further beneficial effects on chest muscle strength and
endurance, as well as workload at AT.
