Walking for the Heart Disease
Walking is one of the most important steps for the recovery of heart disease. Time and speed are two vital aspects of walking for people with heart disease. One must walk for at least thirty five minutes per day.    小题1:    The following understanding will help them to walk.
Why walking?
Walking is a must for a heart patient.    小题2:  First, it reduces weight, controls sugar, and reduces stress. It also gives the joints (关节) enough movement, fresh air – if you walk in the morning. Regular walks help in the control of blood pressure. But the most important advantage is that it gives fitness to the heart.
  小题3:  
Start walking slowly. Gradually increase the speed. Feel when the angina (心绞痛) is about to come. Stop, the feeling will go away. Walk again, but now the speed will be slower than the last time. Keep walking now and the angina will not come. This is the correct speed.  
How to start?
Suppose, you are at the stage of Class I angina: start walking on Day One. Try to walk about 30 minutes. For Class II angina group, walking should be slow and they should start with 10-15 minutes. They should not walk fast. Class III angina patients should start with one minute at home on empty stomach. After two days, they should increase to two minutes.    小题4:  
However, do not walk more than ten minutes a time.
Dos and don’ts on physical activity:
Heart patients must also know that they can do most of the activities where the heart rate does not go up. Sitting in an office, talking over the phone, discussing, driving car are some of the activities which do not increase the heart’s speed.     小题5:   As a matter of fact, stresses can also lead to other illnesses.

B.Walking plays a very important role in helping a heart patient recover.
C.How to roughly judge the proper walking speed?
