Abstract

Aim

The purposes of this meta-analysis were to quantify the effectiveness of physical training on quality of life (QoL), aerobic capacity, and cardiac functioning in older patients with heart failure (HF) and evaluate dose-response relationships of training variables (frequency, volume, and duration). 

Methods

Scholarly databases (e.g., PubMed/MEDLINE, Google Scholar, and Scopus) were searched, identifying randomized controlled trials that investigated the effectiveness of different training modes on QoL (assessed by the Minnesota Living with Heart Failure Questionnaire), aerobic capacity (assessed by the 6 min walk test) and cardiac function (assessed by left ventricular ejection fraction). 

Results

Twenty five studies were included with a total of 2,409 patients. Results showed that exercise training improved total QoL (small ES = −0.69; 95% CI −1.00 to 0.38; p < 0.001), aerobic capacity (small ES = 0.47; 95% CI 0.15-0.71; p = 0.002) and cardiac function (moderate ES = 0.91; 95% CI 0.37-1.45; p = 0.001). In addition, univariate analyses revealed the moderating variable 'training mode' significantly influenced aerobic capacity (Q = 9.97; p = 0.007), whereby, resistance training had the greatest effect (ES = 1.71; 95% CI 1.03-2.39; p < 0.001), followed by aerobic training (ES = 0.51; 95% CI 0.30-0.72; p < 0.001), and combined training (ES = 0.15; 95% CI −0.24 to 0.53; p = 0.45). Meta-regression analysis showed that only the duration of an intervention predicted the effect of physical training on QoL (coefficient = −0.027; p = 0.006), with shorter training durations (12 weeks) showing larger improvements.

Conclusion

The present meta-analysis showed that physical training has positive effects on QoL, aerobic capacity, and cardiac function in older patients with HF. Practitioners should consider both training volume and mode when designing physical training programs in order to improve QoL and aerobic capacity in older patients with HF.
