Abstract

It has been demonstrated that resistance exercises may improve chronic heart failure (CHF) patients' functional ability and quality of life, however, physicians do not recommend this form of exercise because of a concern for reported increases in afterload and blood pressure (BP) during the exercise. This study compared the heart rate (HR), BP and rate pressure product (RPP) of CHF patients for a Balke incremental test and a maximal strength test (MS). Fifteen men diagnosed with CHF participated in the study. All subjects performed both a Balke incremental test and MS test for eight different resistance exercises. The subjects' HR and BP were monitored during the incremental test and immediately after each resistance exercise. HR, systolic BP and RPP were significantly lower during the MS test than during both the peak Balke incremental test and during exercise at 80% of peak VO2 (p < 0.05). No significant RPP differences were found between upper and lower body resistance exercises (p > 0.05). The physiological responses in this study were less severe during a MS test than those reported during an incremental Balke treadmill test. Also the finding suggests that MS tests may be an acceptable method to assess the maximal strength of patients with moderate heart failure.
