Okay so next we want to talk about how exercise
relates 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 millimeters
of mercury on the systolic side. And you have to continue to do that exercise in order for
it to have that effect though. Once you reach that reduced blood pressure you have to maintain
that other wise it will go back up. So we want to talk about, in this series, we want
to 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 careful
when you’re starting a new exercise program. But what we can say is that you should be
breathing briskly. So we will get into the intensity in the next segment, but you should
be doing this brisk walking, jogging, where you can still carry a conversation, but you’re
a little bit winded and you should be doing that for thirty to forty minutes, four to
five times a week. And how this has its effect is it allows the arterial system to be more
responsive to the changing pressures that occur with exercise. And we’ll be demonstrating
that a little bit later, but it’s basically the arterial system has to go a little bit
further and to a wider range of muscles and tissues and so the heart has to work a lot
harder to get that pressure to that area. And when you’re at rest, as your body accommodates
to the exercise that you’re doing, it’s allowed your blood pressure system can make those
changes a little bit easier. So now let’s talk about how to calculate or figure out
how intensely you should be doing this aerobic exercise.
