How hard are your hands and waist when you stand upside down?
There are many requirements for handstand technology, but "top shoulder" is the key. It is not difficult to straighten your arms, but it is not easy to keep your shoulders straight, because the human body is supported and walked with legs in normal life. The trunk itself is supported by only one spine. When standing, use a solid pelvic support, and then use two legs to support. Then when a person stands upside down, the shoulders actually play the role of pelvis when standing, and the weight of the body is mainly borne by the shoulders. The top shoulder needs not only the straightening and exertion of the shoulder joint itself, but also the coordination of the upper limbs, shoulders, chest, waist and back. Including the chest and round back, directly cooperate with the top shoulder to help straighten the shoulder angle; The standing of the waist and buttocks and the straightening of the top legs all use internal forces to reduce the burden on the shoulders. The straighter the shoulders are, the weight of the body is transferred to the ground through the shoulders, upper limbs and palms, giving the ground a vertical downward force, and the reaction force of the ground is transferred upward through the center of gravity to maintain the inverted support of the human body. Therefore, "top shoulder" is the key to handstand training. I said: 1. 1 flexible shoulders. A, the shoulder press and shoulder pull face the handle about one step away, and the arms are lifted up to shoulder width, and the body leans forward to let the hand grasp the handle, including pushing the shoulder to the chest. Stand about a step away with your back to the handle, straighten your arms and lift them shoulder-width. Bend your knees and push down the handle to vibrate up and down repeatedly, and try to open the shoulder angle. Athletes lie prone on the sponge bag, with their shoulders at a distance from the edge of the sponge bag and their arms straight and clamped to their ears. The coach sits on the shoulders of the athletes and pulls up the upper arm. It takes some time to make an array. B. Shoulder swing: After pressing and pulling shoulders, straighten your arms and swing back hand in hand, including chest and stem head. C. Turn your shoulders: Hold both ends of the short stick or rope with both hands, straighten your arms, then go around, and then go around to restore. Pay attention to relax, the distance between your hands is gradually narrowing, and it is not appropriate to rush. D, hanging shoulders: it takes a certain time to hang the horizontal bar before and after. E. Stretch your arms: stand against the wall, lift your arms to touch the wall, put your fingers on them as far as possible, and stretch your shoulders as straight as possible, including your chest. Repeat several times. 1.2 Experience the feeling of lifting shoulders and develop shoulder strength. A. Swing handstand: The body is upright, the hands are upright, the body is upright, and the shoulders are stopped for 3 "-5" each time. B, handstand against the wall: lean forward and lean back, requiring arms to be straight, the body to be straight, and the shoulders to be hard and straight. Keep the highest shoulder posture once 1' ~ 3' and repeat the array. C. handstand on the top bar: put your hands on the vertical line of the bar, with your toes against the lower edge of the bar, or with your feet back to the side of the bar. Push 30 "~ 2' each time, and do 3-5 groups. D, split leg support: straight arms and straight legs are required to stretch the foot surface with high support points, and five fingers crawl for 30 ″ ~1′, making 5-8 groups. E. Comprehensive exercises: lying down, pedaling handstand, push-ups, climbing handstand, lifting handstand, and related upper limb, waist and abdomen strength exercises. After half a year, athletes' shoulder feeling, shoulder strength and finger balance control ability have been greatly improved. Usually, they can push the bar about 2 in the best posture and control the inverted 3 "-5" left stone with help. 2. Controlled handstand is the basis of all handstand movements. Controlled handstand is relatively technical, and many actions are completed by handstand posture. At the same time, it is also a suburban means to improve the special physical fitness. Therefore, in children's gymnastics training, we should pay attention to the training of this movement, lay a good foundation for handstand, and cultivate athletes' interest and serious attitude in teaching methods. 2. 1 master the technical requirements of the empty pendulum handstand: first stand with your legs back and forth, lift your arms up, and then move forward in a lunge ~, with your arms shoulder width apart, your fingers apart, your shoulders open with your chest, and your hands held back. At the same time, your right foot swings up to the handstand and is fixed, and the center of gravity of your left foot moves forward to the shoulder. Jump straight from your left foot to your right foot, at the same time, stretch your hips upright, push your shoulders up with all your strength, and fasten your hands and fingers tightly to the ground. Easy to make mistakes: a, can't control the strength of the swing. B, when the foot is up, the waist and buttocks collapse, and the right foot cannot be fixed, leading to failure. C, the top shoulder is too early, and the center of gravity cannot move up. Teaching measures: A. When the right foot swings to the inverted position, the coach holds the athlete's right foot to help fix it. After the left foot comes up, the athlete's toes press on the coach's palm. After the center of gravity is stable, the coach helps the athletes adjust their balance by supporting and relaxing. B, the coach holds the athlete's shoulders and arms, helps to fix the shoulders, and tries to let the athlete control the time. C. After helping athletes understand the feeling of controlled handstand, coaches should try their best to let athletes practice. D, using the competition, every time the athletes do handstand together, see who finishes it first or who controls the handstand for the longest time. E, for a few players who can't finish the task, ask other players to find reasons for them, help each other, strive to finish the task as soon as possible, and cultivate the spirit of mutual help and friendship among athletes. After one month, the ability of athletes to control handstands has been improved, generally around10 ",and the success rate is 30 ~ 50%. 3. Further experience of inverted control technology proves that with the extension of inverted control time, the success rate of swinging into inverted position will be greatly improved. According to the above teaching methods, stick to 10' controlled handstand practice every day. When the handstand is controlled above 1', girls can have reserved training, and boys can do handstands with handstands or small triangle handstands to further enhance the strength and control ability of shoulder straps. Let the hand fall in all kinds of dynamic and static changes, in all kinds of related action learning and training, and improve it in application.
