How Much Cardio Should a Man Get to Prevent Heart Problems?
Heart disease kills more men than any other cause of death, accounting for about one-quarter of male deaths each year. Examples of heart disease include coronary arterial disease, a buildup of plaque in the arteries; cardiomyopathy, a thickening of the heart muscle; heart failure, inability of the heart to pump enough blood through the body; and heart attack, caused by a blockage of blood flow to the heart. About 50 percent of heart attacks are fatal.
Importance
Physical inactivity is one of the leading risk factors for heart disease such as coronary artery disease. Healthy diet and regular exercise also reduce your risk of developing diseases such as obesity, high cholesterol, high blood pressure and diabetes. According to the Centers for Disease Control, about 90 percent of heart disease patients have at least one of these risk factor diseases.
Intensity
The American Heart Association, or AHA, rates aerobic intensity levels as easy, moderate and vigorous. Moderate and vigorous activities offer the greatest health benefits. Moderate activities should raise your heart rate but still allow you to carry on a conversation, while vigorous activities make it difficult to talk. Examples include walking, housework and recreational sports games such as touch football. Examples of vigorous activity include hiking, jogging, swimming and bicycling.
Duration and Frequency
For maximum health benefits, the American College of Sports Medicine recommends that healthy adults under age 65 do moderate cardio 30 minutes a day, five days a week or intense cardio 20 minutes a day, three days a week. If part of your heart-healthy plan includes weight loss, you may require 60 to 90 minutes of activity on most days of the week. You can break these sessions up into several shorter periods throughout the day.
Benefits
Regular cardio offers a number of health benefits. It can lower blood pressure, help with smoking cessation, control diabetes, manage weight, reduce triglycerides and control cholesterol by raising levels of HDL, or "good" cholesterol. In turn, all of these factors contribute to overall heart and vascular health. A cardio exercise program also improves recovery outlook in heart attack patients.
Fitness Tips
Aerobic activities should increase your heart rate to about 50 to 85 percent of your maximum heart rate, or MHR. For a rough estimate of your MHR, subtract your age from 220. For example, the average MHR range of a 40-year-old man is about 126 to 153 beats per minute. To minimize the risk of injury, consult a physician before beginning any new exercise program.
