Peripheral muscle training with resistance exercise bands in patients with chronic heart failure. Long-term effects on walking distance and quality of life; a pilot study

Abstract

Aims: This study aimed to describe a method of peripheral muscle training with resistance bands in patients with chronic heart failure (CHF) and to evaluate its effects on the 6 min walk test and quality of life up to 12 months using a home-based programme.

Methods and results: Twenty-two patients with stable CHF (19 men and 3 women), mean age 63.2 years (SD 8.1), New York Heart Association class II-III were randomized to individual home-based training (HT group), or home-based training with a group-based start-up in a hospital setting (GT group). A 6 min walk test, the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and Short Form with 36 items (SF-36) were administered at baseline and after 3, 6, 9, and 12 months. Exercise training resulted in statistically significant increased walking distance in both groups. The HT group increased on average 107 (80) m from baseline to 12 months, and the GT group by 100 (96) m. Health-related quality of life, measured with MLHFQ and SF-36, reached statistically significant improvements in both groups but at different time points. There were no statistically significant differences between groups on any parameters or follow-ups.

Conclusions: Long-term home-based peripheral muscle training in patients with CHF, with or without an introductory period in a hospital setting, can be used for initial improvement and retention of walking distance and health-related quality of life.
