Food preparation cannot be omitted:
Firstly, one should increase body heat to adapt to the cold water stimulation during swimming. You can eat some meat, eggs, protein, and also eat some sweets appropriately.
Next is to increase the supplementation of sodium, calcium, and phosphorus. These elements play a crucial role in increasing the excitability of nerves and muscles. In summer, people who sweat a lot and have cramps should also pay attention to supplementing with diluted salt water and vitamin B1. Meanwhile, swimming time should not be too long, and it is not advisable to swim when fatigued or hungry.
The preparation activities should be sufficient:
First, take a cold shower or pat the body and limbs with cold water, and massage the areas that are prone to cramps appropriately. If you can persist in taking cold baths in your daily life, it can improve your body’s ability to adapt to cold water stimulation, effectively avoiding leg cramps during swimming.
Don’t panic if you experience cramps:
When experiencing calf cramps while swimming, it is important to remain calm as panic can cause choking and exacerbate the cramps. Take a deep breath first, dive your head into the water, float your back to the surface, grab your toes with both hands, and pull hard towards yourself, while stretching your legs hard.
If it doesn’t work at once, it can be repeated several times, and the muscles will slowly relax and return to their original state. After landing, dry your body in a timely manner, pay attention to keeping warm, and give appropriate massage to areas that still feel pain to further alleviate it.
