How do gymnasts prevent cocoon 1 How do gymnasts prevent cocoon? It is inevitable for gymnasts to train with sports equipment for a long time, so they should pay attention to nursing at ordinary times. Avoiding the relative displacement between skin and instrument is the key to reduce cocoon formation. Try to wear protective gear on your hands during training. If you hold the equipment in your hand, you can't wrap the pole directly with your palm, but press it with the meat at the root of your finger and then bend your finger. This way of holding the rod can minimize the amount of meat squeezed out from the root of the finger and effectively reduce the relative displacement of the skin contact rod. It should be mentioned that this grip consumes more finger strength than the ordinary bag grasping method, but most people can accept it.

Handshaking posture, generally speaking, is to put on gloves and choose a sponge or patterned rod to increase friction and stabilize our handshaking posture. However, many people still can't hold on to the grip strength in the last few groups of training, because the grip strength is consumed. Gloves are soft and moderately thick: the main thing here is to protect the palm, because when doing pull-ups, the strength of the whole palm is very great, which often causes the skin of the palm to be squeezed and prone to dead meat. Gloves should be longer, fingers exposed, and wrist guards.

2, the harm of excessive exercise When exercising excessively, because the human body consumes a lot of energy, in order to prevent further consumption of energy, there will be functional inhibition. At this time, people will feel extremely tired and weak, and their brain will react slowly. If you exercise excessively for a long time, the sensitivity of the body's protective inhibition function will be reduced, thus damaging the brain function. The main symptoms are: inattention, insomnia, forgetfulness and so on, which will do great harm to human health in the long run. Whether the exercise is moderate or not mainly depends on the heart rate, which should be 60% ~ 85% of the maximum heart rate. It is worth noting that because everyone's actual situation is very different, compared with the quiet heart rate, the difference should be 15% ~ 30%. Exercise according to your own situation.

3. What are the benefits of exercise? Physical exercise has the function of regulating human tension, improving physical and psychological state, and restoring physical strength and energy; Physical exercise can improve physical health, make the tired body have a positive rest, and make people energetically engage in study and work; Stretching your body and mind helps you sleep well and eliminate the pressure brought by reading. Physical exercise can cultivate sentiment, maintain a healthy mentality, give full play to personal enthusiasm, creativity and initiative, thus improving self-confidence and values, and making personality develop healthily and harmoniously in a harmonious atmosphere. Group events and competitions in physical exercise can cultivate people's spirit of unity, cooperation and collectivism.

What to do before exercise 1, you must fully understand your physical fitness before exercise, and it is best to do a professional physical fitness test. For example, patients with cardiovascular diseases, diabetics, severely obese patients and people with serious knee injuries are not suitable for running; Patients with heart disease and hypertension should not swim; People with shoulder and elbow injuries are not suitable for bench press.

It is extremely important to prepare a set of high-quality sports equipment before exercise. Proper running shoes can prevent sports injuries; Comfortable sportswear can improve your sports potential; For girls, a good sports bra can provide professional support for the chest.

Precautions after exercise 1. If you squat down and rest immediately after exercise, it will hinder the blood return of lower limbs. Affect blood circulation and deepen physical fatigue. In severe cases, gravity shock will occur.

2. Exercise often makes people sweat. With the consumption of a lot of water, there is always a feeling of thirst after exercise, and there is an urgent need to drink water. But at this time, the human digestive system is still in a state of inhibition and its function is low. If you eat a lot of cold drinks for a period of time to quench your thirst, it is easy to cause gastrointestinal cramps, abdominal pain and diarrhea, and induce gastrointestinal diseases.

3. During exercise, blood vessels on the body surface dilate, body temperature rises, pores relax, and perspiration increases. If you enter the air-conditioned room immediately after exercise, or take a cold nap at the tuyere, or use a cold water punch to cool down, your skin will be tight and sweaty, causing physiological disorders such as body temperature regulation and decreased immune function, which will lead to diseases such as colds, diarrhea and asthma.
