Exercise And The Heart Beth Kalicki Heli J. Roy, PhD, MBA, RD Pennington Biomedical Research Center Role of Exercise on the Heart Increase in the size and strength of the heart Expansion of the left and right ventricles Thickening of the heart muscle Better delivery of blood to extremities Relaxation between beats changes Reduced heart rate Pennington Biomedical Research Center 6/11/2010 Starting on an exercise program Contact your doctor to see if it is safe to start exercising Stress test Pennington Biomedical Research Center 6/11/2010 Who Can Benefit from Exercise? Everyone can benefit from exercise. Exercise should be performed at a moderate intensity level. Especially patients who have heart failure. Pennington Biomedical Research Center 6/11/2010 Benefits of Exercise Aerobic Exercise is the most beneficial walking, jogging, jumping rope, bicycling Benefits Strengthens the heart Normalization of lipid levels Weight loss Pennington Biomedical Research Center 6/11/2010 Research on the Benefits of Exercise Over 2000 heart failure patients. Separated into two groups: Standard health care Health care and aerobic exercise training After 3 months, the group who exercised, felt better. Less hospitalizations in the exercise group. Pennington Biomedical Research Center 6/11/2010 An active lifestyle leads to 45% lower risk of heart disease Reduced risk of hypertension Helps in hypertension control Can cut the risk for stroke in half Research on the Benefits of Exercise Pennington Biomedical Research Center 6/11/2010 Exercise Precautions Always consult a doctor before you begin any exercise program. Do warm-ups. Drink water before, during and after exercise. Wait 30 minutes after eating. Avoid exercising in high heat and humidity. Avoid strenuous physical labor if you have heart disease or uncontrolled diabetes, seizures, high blood pressure, have had a heart attack within the last six months, have been in heart failure, have unstable angina, a significant valve disease, or those with an aortic aneurysm. Avoid eating right after exercising. Continue moving after a vigorous workout. Pennington Biomedical Research Center 6/11/2010 Other Benefits of Exercise Regular exercise is associated with a delay in onset of dementia and Alzheimer disease. Older adults may have a decreased thirst response to fluid deprivation. Adequate fluid intake is important during exercise. Older individuals who exercise regularly have a lower resting heart rate and blood pressure and improved fitness, balance, and gait. Regular exercise and increased antioxidant nutrient intake will decrease oxidative damage to muscles.
