VOLUME OF EXERCISE PERFORMED BY HEART FAILURE INPATIENTS UNDERGOING CARDIAC REHABILITATION - A QUASI-EXPERIMENTAL STUDY
| Resumo: | Abstract Introduction: Heart Failure inpatients have a significant functional dependence, impairment of performance in activities of daily living, and low exercise tolerance. The amount of exercise is directly related to its benefits, and the exercise volume must be adjusted to address safety issues. This study aims to evaluate the volume of exercise performed and its relationship with functional capacity and determine a safe and effective baseline volume level. Methodology: Quasi-experimental study involving 50 inpatients who performed an aerobic exercise training program. The exercise volume was registered regarding the number of cycle ergometer turns, meters walked, steps climbed, and the total time exercising. Subjective perception of exertion was evaluated in every training session at the beginning and the end. Patients performed two 6-minute walking tests (6MWT). Results: 987 exercise sessions were performed. Most of the patients were significantly impaired: 81.9% are NYHA III, and 73.6% present HFrEF. Patients achieved lower levels of perceived exertion throughout the hospital stay: 6 (±3) (admission) and 2(±2) (discharge). Patients with more exercise volume walked a higher distance in the discharge 6MWT. Conclusion: A higher volume of aerobic exercise is related to a better improvement in functional outcomes. An average of more than 10 minutes per session seems more effective in improving the functional capacity. |
