Swimming legs cramps and toes quickly
The sun is scorching, the heat is steaming, and the asphalt road is soft and the feet are on the asphalt. Xiaoying and her classmate Zhao Lan went to the swimming pool to swim. Along the way, the two of them were sweating all over. When they passed by the popsicle stall, Xiaoying bought two popsicle sticks, and after eating, she entered the swimming pool with her classmates.
The pool water has just been changed, with azure blue waves, which is very cool. Xiaoying changed into a swimsuit every time, rushed down and jumped into the swimming pool. Zhao Lan was not as neat as she was, and she was still grinding carefully, taking a shower, doing exercises, and exercising her body. It was not until Xiaoying finished swimming 50 meters before she got into the water.
On the second 50-meter swimming lane, Xiaoying felt something was wrong. Her calves became heavier and heavier, and she became cramps. She gritted her teeth and wanted to swim for the last ten meters, but her legs were as heavy as lead. In the end, she couldn't stretch her calf and could not bend it. The pain made her grab the pool wall sideways and was helped by Zhao Lan.
In the swimming pool infirmary, Coach Wang and Dr. Li gave Xiaoying a massage. Dr. Li told her: "When it's hot, the body expels a lot of sweat in order to regulate the body temperature. The hotter the weather, the bigger the pores of sweating. At this time, you can't enter the water all at once. The cold air injects, which is very susceptible to cold cramps." Coach Wang said: "If the body does not move seriously in the body before going into the water, cramps are inevitable. Before going into the water, shower well and adapt to the water temperature is definitely not an optional form. The joints of the legs, arms, and buttocks must be moved before swimming." After saying that, he walked to the pool, jumped into the pool, and demonstrated, "You see, you should be relaxed and relaxed in swimming, and you cannot swim desperately. If you cramp, stretch your legs and raise your toes upwards, and narrow the angle between your calves and feet, the cramps can be alleviated." Finally, he summarized a few points and let them remember:
1. When it is hot, do not sweat profusely and then go into the water. You can drink some cold drinks first to lower your body temperature, and then go into the water after sweating.
2. Joint movements should not be underestimated. You must do a set of gymnastics before going into the water.
3. You can’t keep playing speed in the water, because any movement must be progressive step by step, and you must change your swimming posture slowly and quickly. Once you have cramps, it is best to float on the water surface and stretch your toes. After relieving it, use another swimming posture to swim back to the shore and go ashore to rest.
