Exercise is important for cardiovascular health because it?

Answer 1

Exercising improves health by reducing major risk factors for cardiovascular disease (sedentary lifestyle, high blood pressure, high blood cholesterol, and obesity). Exercising reduces body weight preventing obesity, reduces Low Density Lipoprotein, which is the bad cholesterol that moves fat to veins, increases High Density Lipoprotein which then again takes the LDL away to different tissues, increases insulin sensitivity and lowers blood sugar preventing Diabetes, and reduces blood pressure (protects against hypertension). Exercising also improves the body's ability to take in and use oxygen, decreasing the workload and oxygen demands on the heart.

Answer 2

That is a very good question. Exercise can increase your cardiac output up to 25 litre/minute. Your heart rate may go up to 180 / minute. When blood is pumped in the arterial system with such a high speed and high volume, your arterial system dilates as a whole. It dilates and contracts. This prevents any deposition of the lipid substance on the inner wall of the arteries. So atheroscelosis is largely prevented and elasticity of the arterial system is maintained. So you can forget the heart attack, when you achieve the high heart rate even for two minutes daily by the way of exercise.

Answer 3

The human heart is a muscle that needs exercise to help keep it in shape. Exercise can help prevent many heart related diseases.
