Regular aerobic exercise plays a significant role in preventing heart and blood vessel disease. For some years the AHA has recommended 30-60 minutes of aerobic exercise three to four times per week to promote cardiovascular fitness. Such activities could include aerobics, jogging, running, swimming and sports such as tennis, racquetball, soccer and basketball. Even modest levels of low-intensity physical activity are beneficial if done regularly and long term. Such activities include walking for pleasure, gardening, house work and dancing.
Physical inactivity can lead to several changes that are risk factors for heart disease.
When lack of exercise is combined with overeating, excess weight and increased blood cholesterol levels can result and these unquestionably contribute to the risk of heart disease. Middle-aged or older people who are inactive should seek medical advice before they start or significantly increase their physical activity.
