Two hours of moderate exercise every week can reduce the risk of developing heart disease by 30%. select the best answer from the choices provided. t f

True.

Explanation:

Exercise has several important effects, such as lowering blood pressure, bad cholesterol, blood glucose, triglycerides, and inflammatory markers; increase good cholesterol (which removes fat from vessels); and increase the heart's ability to pump blood (which fights heart failure). A few hours of exercise a week (two hours, for example) is enough to reduce the risk of developing heart disease by 30%.

A number of mechanisms are involved in this process. One key is that being active increases the presence of nitric acid in cells, a substance that "relaxes" artery walls. There is also a drop in norepinephrine levels, a stress hormone that raises blood pressure and heart rate to get us ready in dangerous situations. And raising good cholesterol still helps to get fat from the arteries to the liver for metabolism.
