Okay so next we want to talk about how exerciserelates to blood pressure. There’s some research done on how exercise can reduce blood pressure.And they found that exercise can reduce your blood pressure by as much as ten millimetersof mercury on the systolic side. And you have to continue to do that exercise in order forit to have that effect though. Once you reach that reduced blood pressure you have to maintainthat other wise it will go back up. So we want to talk about, in this series, we wantto talk about the kinds of exercise, the duration of exercise, and the intensity of the exercise.So what kinds of exercise have this effect on blood pressure? Mainly aerobic exercise.So aerobic exercise can be different things
for different people, and you need to be carefulwhen you’re starting a new exercise program. But what we can say is that you should bebreathing briskly. So we will get into the intensity in the next segment, but you shouldbe doing this brisk walking, jogging, where you can still carry a conversation, but you’rea little bit winded and you should be doing that for thirty to forty minutes, four tofive times a week. And how this has its effect is it allows the arterial system to be moreresponsive to the changing pressures that occur with exercise. And we’ll be demonstratingthat a little bit later, but it’s basically the arterial system has to go a little bitfurther and to a wider range of muscles and
tissues and so the heart has to work a lotharder to get that pressure to that area. And when you’re at rest, as your body accommodatesto the exercise that you’re doing, it’s allowed your blood pressure system can make thosechanges a little bit easier. So now let’s talk about how to calculate or figure outhow intensely you should be doing this aerobic exercise..
