2, swimming precautions
(1) Physical examination
Because when swimming, people consume eight times as much physical strength as usual, so people with heart disease, active tuberculosis, liver disease and kidney disease should not take part in swimming. People with pink eye and infectious skin diseases should not swim to avoid mutual infection.
(2) Warm-up exercise
Do warm-up activities on the shore before launching, or suddenly do more intense activities, which may easily cause muscle injury or other accidents. Lift your legs, squat, and stand up.
(3) Preventive measures
When diving, you must find out the water depth and underwater conditions to prevent accidents such as bumps and injuries, and at the same time avoid the abdomen and testicles being directly hit by water. Also protect the ear, because the ear is hit hard by water, which will make the eardrum sag inward and even rupture, leading to deafness. If there is water in the nose, don't pinch your nose and blow hard, which will easily squeeze the water from the nasopharyngeal cavity into the middle ear through the eustachian tube, causing otitis media.
After swimming, rinse the whole body with clean water again to avoid infectious diseases. Generally, swimming pools have showers.
3. What about swimming leg cramps?
1, stay calm
If you have leg cramps while swimming, you must keep calm. If the head is still on the water, call for help immediately and cooperate with rescuers to get out of the water safely. If the head is underwater, try to make the body surface as much as possible, and then call for help, or use the following self-help methods to relieve cramps.
2, instep upturning method
When leg cramps occur during swimming, the instep should be pushed upward as quickly as possible and fixed in this position. Generally, it can effectively relieve cramps within 30 seconds, and then keep the instep up for about 3 minutes to consolidate the curative effect. The direction of instep upward is the direction of spasmolysis, so it is normal to have severe pain in the early stage.
Step 3 press the leg rubbing method
Press the palm root inside and outside the calf, press the palm root relatively hard, and massage the gastrocnemius for about 2 minutes. Pressing this part is to relax muscles, promote blood circulation, and treat calf pain after spasms are relieved.
4. Grab your toes with both hands and pull hard.
If you have cramps when swimming in shallow water, you can take a deep breath, dive your head into the water, try to make your back surface, grab your toes with your fists and pull in the direction of your body. At the same time, the legs shake hard, and after repeated stretching several times, the muscles will slowly relax and recover. When the spasm is subjected to a certain external force, you can eliminate the spasm.
