Routine physical activity can improve exercise tolerance in individuals with chronic heart failure (HF). Lack of exercise can lead to worsening of HF. This study examined the effect of a pedometer on exercise tolerance in veterans with chronic HF. Although both pedometer and routine exercise groups improved 6-minute walk test distance, the use of a pedometer was not better than routine exercise in improvement in exercise tolerance after 6 weeks. Factors that may have impacted the effectiveness of pedometer use include pedometer malfunction, low pedometer compliance, and severe wintery weather. |
