Swimming heart rate

In our lives, many people like swimming very much, because swimming can make the muscles of the whole body move, and this sport can not only consider a person's lung capacity but also a person's heart function. People with heart disease must not swim. Some people will measure their heart rate after swimming, so is it accurate to measure heart rate while swimming?

Exercise will make the heart muscle stronger, enhance the heart's ability to transport blood, and enhance the body's oxygen exchange and metabolism, thereby lowering the heart rate. Therefore, athletes generally have a lower heart rate, which is a good phenomenon.

Medically speaking, a heart rate below 60 beats/minute is called "bradycardia", which is based on the lower limit of 60 beats/minute for the average person (not very young athletes). It does not mean that bradycardia is a disease, nor is it always caused by nerve conduction or quality diseases.

Precautions for swimming

First, warming up before exercise is essential, not just swimming, but any exercise requires warming up. Be sure to do warm-up exercises before entering the water, and it is best to adapt to the water temperature before entering the water.

Second, avoid swimming before or after meals. Swimming on an empty stomach will affect appetite and digestive function, and will also cause dizziness and fatigue during swimming. Swimming on a full stomach will also affect digestive function, and will cause vomiting and abdominal pain due to water pressure.

Third, avoid eating immediately after swimming, and you should not eat immediately after exercise. It is advisable to rest for a while after swimming before eating, otherwise it will suddenly increase the burden on the gastrointestinal tract.

Fourth, avoid swimming after strenuous exercise. You should rest and restore your strength after strenuous exercise instead of buying another sport, which will increase the burden on your heart.

Fifth, avoid swimming after drinking. Alcohol will paralyze your brain. In addition, alcohol can inhibit the normal physiological functions of the liver, hinder the conversion and storage of glucose in the body, and thus cause accidents.

Sixth, avoid swimming for too long. Swimming will consume a lot of body calories. Swimming for too long can cause cramps, dizziness, etc. Normal swimming should not exceed 1 hour. Generally speaking, 40 minutes is most appropriate.
