How to prevent dizziness and leg cramps during swimming?
When you are new to swimming, a few people will experience dizziness after getting into the water, which is often accompanied by panic and suffocation. What is the reason for this? This is mainly related to being unfamiliar with water. After people enter the water, the environment is very different from the usual land. The rippling and rolling water waves, especially when swimming in non-swimming pool water, the human visual and auditory systems are greatly stimulated. Coupled with the refraction of light in water, the stimulation and impact on these systems make people prone to dizziness. In addition, the special requirements for the body's balanced position in water, the up and down fluctuations and oscillations of the body's buoyancy under water, and the repeated breathing movements of the head entering, exiting, and turning left and right during swimming, the requirements for the body's balance organs are much higher than usual on land. This makes it easy for some people who have never swim in the water, especially those who lack exercise in balance organ function, to develop dizziness. After encountering this situation, you can go ashore and rest for a while, and the dizziness will soon pass. After repeated and repeated drainage activities and adapting to the buoyancy, pressure and resistance of the water, you can become familiar with the water properties and overcome dizziness.
Another situation of dizziness is due to low water temperature and cool weather, especially those who are in poor health or have not been swimming for a long time, they will also feel dizzy after getting into the water. The reason for dizziness at this time is caused by the stimulation of cold water, which causes dysfunction of vasoconstriction and diastolic function, and dysfunction of the autonomic nervous system. This situation is more common in the early stages of swimming season, and lesbians are more likely to occur. When dizziness occurs in this reason, go to the rocks immediately to rest, pay attention to keeping warm, drink some hot water, and it will usually improve soon.
Some people go into the water without preparing for activities, engage in strenuous activities immediately in the water, or swim in the water and stay for too long, which can also cause dizziness. This can be a sign of low body function.
Another phenomenon closely related to the above-mentioned cold water stimulation, staying in the water for too long or not sufficient preparation activities is leg cramps during swimming. This is a common problem encountered in swimming. Cramps are the phenomenon of muscle contraction. Leg cramps during swimming often occur in the calf. The reasons for this include: the intensity of lower limb movements, inconsistent movements between the lower limbs; excessive fatigue in body; local muscle fatigue or excessive mental tension. The first way to prevent is to take corresponding measures according to the different reasons. First, make sufficient preparations before going into the water so that the joints and muscles in various parts of the body can be fully activated. Do not immediately perform vigorous swimming activities after getting into the water. First, pat the whole body with water, especially the lower limbs, and do some stretching of the lower limb muscles. Only on the basis of the movement, gradually increase the amount of swimming exercise. For most swimmers, it is not advisable to go ashore and enter the water repeatedly. Do not exercise in the water for too long, especially when the water temperature is low. People who often experience calf cramps should be careful to prepare their activities and do more exercises to stretch, pull and knead the calf muscles. If leg cramps still occur after these sufficient preparations, you should ask a doctor to treat it.
When leg cramps occur in the water, don’t panic first, and stay calm and awake. Try not to mess up the swimming movements and not to destroy the breathing rhythm. People with a certain swimming level can get rid of themselves in the water. The way to get rid of it is to take a breath first, then knead your calves with your hands in the water, and lift your feet upwards with force to pull the cramped muscles, persist for a while, so that the contracted muscles can relax, and then go ashore. You can also use limbs without cramps to swim slowly on the shore or backstroke before you can get free. If you are not sure of liberation, you should wave to help as soon as possible. If you panic, move or breathe disorder, it will cause choking or cramps in other parts, which must be prevented.
