People's heart rate will increase during exercise. The greater the exercise, the faster the heart rate. If the heart rate does not increase significantly during exercise, it may be an early signal of heart disease, indicating the danger of angina pectoris, myocardial infarction and sudden death in the future.

2. Angina pectoris during exercise:

Exercise increases myocardial load and increases myocardial oxygen consumption. Especially for some middle-aged and elderly people with different degrees of arteriosclerosis, the relative blood supply to the heart will be insufficient during exercise, leading to coronary artery spasm and angina pectoris. In this case, exercise should be stopped in time, and taking nitroglycerin tablets under the tongue can generally eliminate angina pectoris.

3. Headache during exercise:

A few patients with heart disease don't feel abnormal in the chest when they get sick, but they will have a headache when they exercise. Most people just think that they have not had a good rest or caught a cold. Therefore, remind those friends who participate in sports that if they feel headache during exercise, they should go to the hospital for examination as soon as possible.

4. Abdominal pain during exercise:

In the process of exercise, abdominal pain suddenly appears, mostly due to a large amount of sweating caused by rectus abdominis spasm, losing water and salt. When you have abdominal pain, you should do abdominal breathing on your back for 20-30 times and gently massage the rectus abdominis for about 5 minutes to relieve the pain. Excessive sweating during exercise, timely supplementation of 200-300ml physiological saline is the key to prevention.

5. Abdominal colic occurs during exercise:

Epigastric colic is more common in stomach cramps such as low water temperature, insufficient preparation and excessive exercise when swimming. At this time, you can do hot compress on the upper abdomen for 20-30 minutes, and press Neiguan and Zusanli points by hand for 3-5 minutes. To prevent stomach cramps, make full preparations before exercise, avoid being full, avoid eating beans, sweet potatoes and other foods, and eat less cold drinks. When exercising, there is dull pain and swelling around the navel or lower abdomen, mostly intestinal spasm. At this time, as long as you stop exercising, the pain can be alleviated. You can also massage bilateral joint points for 5 minutes by hand, or apply hot water to umbilical region 10-20 minutes to relieve pain. In order to prevent the occurrence of intestinal spasm, we should make full preparations before exercise and avoid eating cold food.
