00:01.040 --> 00:03.200
regular physical activity can lower

00:03.200 --> 00:05.330
many risk factors for coronary artery

00:05.330 --> 00:07.600
disease . Captain Miller , can you

00:07.600 --> 00:09.544
explain how exercise affects heart

00:09.544 --> 00:11.750
health , definitely dr phillips .

00:12.240 --> 00:14.407
Physical activity is an important part

00:14.407 --> 00:16.073
of reducing the risk for Disl

00:16.073 --> 00:18.330
epidemiology , hypertension , insulin

00:18.330 --> 00:20.840
resistance and obesity , which are four

00:20.840 --> 00:23.007
major risk factors for coronary artery

00:23.007 --> 00:26.180
disease . Exercise increases HDL or

00:26.180 --> 00:28.110
good cholesterol levels and helps

00:28.110 --> 00:30.500
control blood pressure . It also helps

00:30.510 --> 00:32.780
insulin absorb glucose into the body's

00:32.780 --> 00:34.830
cells , including the muscles . For

00:34.830 --> 00:37.410
energy , muscles use glucose better

00:37.410 --> 00:39.610
than fat does . So building and using

00:39.610 --> 00:41.870
muscle through physical activity can

00:41.870 --> 00:44.590
help control blood glucose . Perhaps

00:44.590 --> 00:46.830
most importantly , routine physical

00:46.830 --> 00:49.020
activity is a key element in achieving

00:49.020 --> 00:50.964
and maintaining a healthy weight ,

00:50.964 --> 00:53.020
which lowers the risk for all of the

00:53.020 --> 00:54.909
conditions that contribute to the

00:54.909 --> 00:57.187
development of coronary artery disease .

00:57.187 --> 00:59.242
Aerobic exercise , which is exercise

00:59.242 --> 01:01.353
that uses oxygen to provide energy to

01:01.353 --> 01:03.970
large muscles , raises both heart and

01:03.970 --> 01:06.580
breathing rates . Examples are running

01:06.590 --> 01:09.380
brisk walking , cycling or swimming .

01:09.530 --> 01:11.697
These kinds of exercises are important

01:11.697 --> 01:13.863
for conditioning and strengthening the

01:13.863 --> 01:15.974
heart and lungs . It's usually a good

01:15.974 --> 01:18.141
idea to start out slowly and gradually

01:18.141 --> 01:20.470
build up to a full program . It's also

01:20.470 --> 01:22.526
important to select an activity that

01:22.526 --> 01:24.470
you really enjoy and to use a self

01:24.470 --> 01:26.526
monitoring device , such as a mobile

01:26.526 --> 01:28.692
app or a pedometer to encourage you to

01:28.692 --> 01:30.914
stick with it . It's easier to maintain

01:30.914 --> 01:33.081
a routine when you have goals that are

01:33.081 --> 01:34.803
easy to track and you're doing

01:34.803 --> 01:34.850
something that you enjoy .
