The Effect of Resistance Training on Sarcopenia in Older Heart Failure Patients

Summary

The goal of study is to evaluate the effects of an eight-week machine-based resistance training program on managing sarcopenia in older outpatients with chronic heart failure (HF) at Military Hospital 175.

Eligibility

Inclusion Criteria:
