简要总结
Background: Heart failure is described by a lack of confirmed efficient therapies and exercise intolerance. Physical activity is related to a lower risk of adverse cardiovascular consequences, involving heart failure. The purpose of the study: determine the effect of different types of aerobic training on peak VO2 and ejection fraction in diastolic heart failure patients. Subject and methods: Forty eligible male patients with diastolic heart failure, aged between 50 - 60 years old, participated in this study. They were selected from an outpatient clinic of general Zagazig hospital and were assigned into 2 equal groups in numbers. The first group (A) received aerobic exercise for the upper limb in form of arm ergometer exercises, while the second group (B) received aerobic exercise for the lower limb in form of cycling. Training duration for both groups was 3 sessions/week for 12 weeks. Peak VO2, and ejection fraction of both groups were measured and compared pre and post-treatment. Results: There was no significant difference in the ejection fraction between groups post-treatment. There was a significant increase in the peak VO2 of group B compared with that of group A post-treatment. Conclusion: there is no effect of different types of aerobic training on ejection fraction and peak VO2 for diastolic heart failure patients, but lower limb exercise is more effective than upper limb exercise in improvement of peak VO2 for diastolic heart failure patients.
详细描述
Ejection fraction and peak VO2 of both groups were measured pre exercise program and after 12 weeks at the end of the study exercise program.
- Vivid S5 cardiovascular ultrasound system (BT308), made in china, was used to measure ejection fraction.
- Oxycon pro (ER900, Germany) cardiopulmonary exercise test unit was used to measure Peak Vo2
Treatment procedure:
Group A received aerobic exercise for upper limb in the form of arm ergometer 3 session/week for 12 weeks. Patient started with warming up for 5 minutes in form of stretching. Patients used arm ergometer without resistance for upper limb aerobic exercise for 20 minutes and instructed to take rest if they feel tired or fatigue. The intensity was according to rate of perceive exertion, after 20 minutes, patients were asked to cool down for 5 minutes in the form of stretching at the end of an exercise session.
Group B received aerobic exercise for lower limb in the form of cycling 3session/week for 12 weeks. Patient started with warming up for 5 minutes. Patients used bicycle for lower limb aerobic exercise for 20 minutes and instructed to take rest if they feel tired or fatigue. The intensity was according to rate of perceive exertion. After 20 minutes, patients were asked to cool down for 5 minutes in the form of stretching at the end of an exercise session.
