Aerobic Exercise is the most beneficial walking, jogging,
jumping rope, bicycling
Benefits Strengthens the heart Normalization of lipid
levels Weight loss

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.

– 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

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.

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.
