Exercise

Exercise is essential to a healthy body. A sedentary lifestyle can lead coronary artery disease, obesity, high blood pressure (hypertension), and a low level of high density lipids (HDL) cholesterol. Studies show that people who exercise regularly after heart surgery have a better survival rate.

Exercise can improve your muscular and skeletal systems, benefit your heart and circulatory system, and improve your flexibility. When you increase your heart rate during exercise, you improve the efficiency of your heart. You build stronger bones and muscles, which makes the frame of your body stronger. In addition, you increase your flexibility, which will decrease your chance for injury and bodily aches.

Healthy individuals should exercise for at least 30 minutes, three to four days a week. This should be done at 50 to 75 percent of your maximum heart rate. Good exercises include brisk walking, stair-climbing, running, bicycling, swimming, or a sport such as basketball. Remember it is always best to consult your physician or another trained professional if you are just starting to exercise.

The American Heart Association has created the following table to outline estimated target heart rates.


Age Target Heart Rate Zone
50-75%
Average Maximum
Heart Rate 100%
20 years 100-150 beats per minute 200
25 years 98-146 beats per minute 195
30 years 95-142 beats per minute 190
35 years 93-138 beats per minute 185
40 years 90-135 beats per minute 180
45 years 88-131 beats per minute 175
50 years 85-127 beats per minute 170
55 years 83-123 beats per minute 165
60 years 80-120 beats per minute 160
65 years 78-116 beats per minute 155
70 years 75-113 beats per minute 150

Studies prove that people who exercise consistently are more likely to decrease their smoking habits or stop smoking altogether. People are less likely to develop diabetes when they are at their ideal weight. Furthermore, exercise may decrease a diabetic's requirements for insulin. One of the cholesterol-carrying proteins in the blood, high density lipids, is increased with regular activity. These lipids carry harmful cholesterol through your bloodstream so it doesn't build up and cause CAD.

In addition to improving your physical body, regular exercise has been linked to psychological benefits. It reduces feelings of depression and anxiety, improves mood, and promotes a feeling of well-being.
