Essentials and precautions of high-altitude diving
The essentials and precautions of high-altitude diving are as follows:

Key points of high-altitude diving:

1. Swimmers buckle their five toes on the front edge of the platform, look forward, concentrate and make a good start. Their feet are about 6- 12 inches apart.

2. Govin made an ideal starting posture for every swimmer, with his torso bent forward, his knees slightly bent, his arms vertical, his palms backward, his head raised, and his line of sight about 12 meters. Swimmers should feel that their center of gravity is outside the pedal and can keep their balance. Then concentrate on listening to the gunshots and react quickly.

After the gunshot, the swimmer swings his arm up, back and forward. Bow your head, bend your ankles and move your knees forward.

4. When the elbow swings the arm again, it keeps stretching, and the head begins to lift, just like the arm movement, transferring momentum to the body.

5, the arm reaches the highest point, the heel is raised, and the head continues to rise. The center of gravity of the body exceeds the front of the toes, and the left hip joint of the body continues to flex.

6. When the hand swings downward and forwards, and the knee joint and ankle joint are extended, the swimmer should feel that all movements are forward.

7. The swimmer begins to inhale. The movements of the head and arms stop at the same time, and the arms remain inclined downward, and the momentum of the head and arms is transferred to the body, pulling the body upward and outward.

8. When the legs are fully extended, the ankle joint bends, giving the body the final propulsion.

9. Swimmers stretch their bodies and fly in the air in a streamlined posture.

10, when the swimmer touches the water, the two halls keep close together and touch the water first, and the head is slightly lower when entering the water. Abdominal muscles contract, knees and ankles stretch, making the body streamlined. Swimmers should imagine stretching their bodies without feeling relaxed.

1 1, the body sinks into the water, and there is a tendency to continue to sink. At this point, the swimmer's head is slightly raised, and the palm is the rudder, so that the body is slightly upward. When a swimmer slows down to swimming speed and his head is a few inches above the water, he should start paddling and kicking at the same time. If he sinks too deep, he can paddle once or twice to make his body surface. The number of strokes before breathing determines the distance a swimmer swims.

Matters needing attention in high-altitude diving:

1, jump

Taking off upwards can give you more time in the air, better find the landing position and adjust the balance more accurately, so when taking off at high altitude, try to make your body send an upward force from your legs, make your movements more graceful and smooth, and improve your own safety.

2. Balance.

This problem is complicated, you just need to remember: keep nervous, keep a clear head and be flexible. First, find the approximate landing position. If the jumping point is higher, it is suitable for landing at a slightly farther place, and the lower one is suitable for landing at a closer place.

Try to reduce your body area in the air and reduce the influence of air resistance on your body. Put your hands in a comfortable position and don't swing from side to side to prevent the center of gravity from changing because of your hands. Don't lean back too straight in the upper body to prevent the center of gravity from leaning back. The body should be slightly bent and slightly warped, and the waist should be tense and hard to maintain its sense of balance in the air to the maximum extent.

Step 3 land.

At the moment of landing, the ankle is stressed, the upper body leans forward, and the lower limbs land with both hands. This is very important, because if the body is vertical at the moment of landing at high altitude, it will not be well connected with the landing buffer, causing physical injury caused by gravity.

You can't close your eyes at the moment of landing. Always open your eyes to form a correct sense of distance and better grasp the time of ankle exertion. This is beneficial to the stability of landing. After landing, it should be connected with the rollover to play a buffering role. Rollover should be used before the landing leg bends, rather than crouching down after landing to cushion by its own gravity.

High altitude diving accident:

If the diver's head falls into the pool first, it will cause a serious concussion, and even meet skull fracture's bad luck, which may lead to his death on the spot. Tony Avery, the fitness coach of the British diving team who won the Olympic Games and the Commonwealth diving competition three times, said: "Jumping from such a high place will have an incredible impact-almost like falling on the concrete floor."

In order to keep the body in a perfect state, high-altitude divers must undergo strict training in order to cope with the huge impact when colliding with water. When divers touch the water, due to the great influence of gravity on their bodies, they often encounter spasms and spasms, and a large amount of adrenaline will flow into blood vessels.

Because this is a hard sport, high-altitude divers can only jump 15 times a day at most, and they must receive muscle tissue massage immediately after each dive.
