How do weightlifters protect their upper limb joints

Generally, warm-up exercises and acclimatization exercises before the game can effectively prevent uncomfortable symptoms such as muscle strain.

1) Athletes weigh their weights 2 hours before the competition, and the time for weighing is 1 hour;

2) During the competition, perform the snatch first, rest for 10 minutes and then perform the clean and jerk;

3) The number of attempts of athletes in the snatch and clean and jerk is 3 times;

4) The order of play is based on the weight required by the athletes, the order of the draw in advance, and the number of lifts. The light weight to be lifted first when trying to lift. If the weight of the first attempt is the same, the one with the smaller number will lift first.

If the weight of the first lift is the same, the one with the fewest lifts will lift first. If the number of attempts is the same, the last one will still be the first;

5) The weight of the barbell on the playing field can only be increased, not decreased. After each successful lift, a multiple of 1 kg must be added;

6) The ranking is determined by the sum of the snatch and clean and jerk in the Olympic Games. If the overall score is the same, the lightweight one will be ranked first. If the weight is the same, then the first place to complete the overall score is in the first place, and it is not allowed to tie the ranking;

7) The trial time for the sports finch finger members is set to 1 minute. From the point to the end of the athlete's name or the aggravation of the player on the field, the time of the end of the two items shall prevail. If an athlete tries to lift continuously, it will be 2 minutes.

If the barbell does not lift the knee within this time, it is considered a failure.

It is magnesium powder that plays an anti-slip role.

What are spectators doing when they can see athletes standing in front of a white cylinder and rubbing white powder back and forth with their hands before getting on the machine? This is rubbing a non-slip magnesium carbonate powder; The aim is to increase the friction between the palm of the hand and the instrument and prevent the hand from falling off the bar. Without the use of anti-slip agents such as magnesium powder, it is difficult for athletes to complete difficult movements such as horizontal bars, rings, and parallel bars, which shows the importance of carefully applying magnesium powder before athletes get on the equipment.

Why in gymnastics competitions, male athletes sometimes wear long pants; Sometimes wearing shorts? When we compete in men's gymnastics, we will find that athletes wear long gymnastics pants on the court in some events, while in shorts in others, and even some athletes even compete barefoot, why is this? The international gymnastics scoring rules clearly stipulate that in all team competitions, athletes must wear uniform clothing, in the pommel horse, rings, parallel bars, horizontal bar four events; Be sure to wear a tank top.

Long gymnastics pants, gymnastic shoes (or socks). The reason for this rule is that these four events are mainly based on upper limb movements, and wearing long pants not only has little impact on athletes' movements, but also can increase the beauty of movements. In the two events of floor exercise and vault, basically the whole body has to participate in sports, especially the leg activities, in order to ensure that athletes can better perform in the competition and create better results; The rules stipulate that in both events, shorts can be worn or barefoot (to prevent slipping).

If an athlete violates these rules, a certain number of points will be deducted from the total team score or individual score.

Because the waist is the support of the upper and lower limbs.

Lifting weights that are too strong and the strength of the transition from the lower limbs to the upper limbs are all through the waist.

The waist is very brittle, so add waist protection to make the waist evenly stressed and safer.

The main joints often used by the human body during exercise, such as the shoulder joint, shoulder joint, elbow joint, ankle joint, wrist joint, knuckle joint and other sports of the upper limbs, the elbow joint, wrist joint and ankle joint are more active, so the preparatory activities for these joints should be done, and appropriate activities should be carried out to avoid joint or muscle injuries caused by sudden strenuous exercise, such as wearing knee and wrist braces, appropriate exercise intensity, etc

Therefore, the answer is: shoulder joint, elbow joint, ankle joint, wrist joint, knuckle joint, etc.; Wear knee pads and wrist pads, exercise intensity is appropriate, etc

1.Back extensor exercises in the supine position.

1) Five-point support method: take the supine position, bend the elbows and knees on both sides, use the head, feet, and elbows as support, and arch the waist vigorously (you can also use the palms of both hands to support the waist arch), and practice repeatedly.

2) Three-point support method: After the five-point support exercise, those with better waist muscles can put their arms in front of their chests, use the head and feet as support, and do the arch waist exercise hard, repeating many times.

3) Four-point support method: that is, on the basis of the former, the four-point support of both hands and feet is used as an arch bridge exercise, which is repeated many times.

2.Exercise in the prone position.

1) Lie on your stomach with your head up, chest and arms, and straighten your upper limbs on both sides of your torso, raise your head and chest, and exercise repeatedly.

2) Straighten and raise your legs: The basic posture is the same as before, change the head and chest to the straight and raise the legs, and repeat the exercise.

3) Raise your head and chest and legs (also known as Feiyan pose): Combine the first two, implant the bed with the abdomen, and lift the head, hands and chest and two lower limbs together, repeating many times.

3.Lumbar swing exercises.

Stand with your feet shoulder-width apart, cross your hands on your hips, and rotate your waist in a clockwise and counterclockwise direction, from slow to fast, from small to large, repeatedly.

There are many ways to build upper body strength, and here are some of the exercises and some of its basic requirements.

1. Push-up exercises: the position of the two-handed support is close to the abdomen, the body is kept in a plane, the support is fast and slow, and the body does not collapse, 10-20 times per group.

2. Standing push-up exercises: When doing push-ups, the body should not touch the ground, stand with the abdomen folded while holding up, and the other requirements are the same as push-ups, 10-20 times per group.

3. Dumbbell lifting exercises: stand naturally with both feet, upper body upright, chest up and head up, arms bent and arms raised quickly, and slowly fall. When falling, the shoulders are opened, 30-40 reps per set (weight optional).

4. Dumbbell arm flexion and extension exercises: both arms are carried out at the same time or crossed, and the upper body is kept upright, 20-30 times per group.

5. Barbell jerk exercises: the feet are naturally open or the same width as the shoulders, when lifting the wrists, the elbow joint is lifted forward, and the jerks can be stepped or strided, 5-10 times per group (weight optional, pay attention to safety).

6. Barbell snatching exercises: two feet are the same width as the shoulders, the two hands hold the bar wider than the shoulders, and at the same time quickly turn the wrist and stretch the top shoulders to lift, 5-10 times per group (weight optional).

7. Pull-up exercises: hold the bar with both hands, the width of the bar is the same width as the shoulder, and the body should not swing left and right, 10-20 times per group. 8. Parallel bars arm flexion and extension exercises: choose low parallel bars, keep the body perpendicular to the ground during the exercise, 5-10 reps per group.

9. Combined equipment exercises: use combined equipment to develop upper limb strength exercises, group them according to physical fitness, and keep the number of exercises at 10-20 times.

10. Throwing solid ball practice: practice carefully, reasonably group, pay attention to safety, 20-40 times per group.

There are many, many ways to exercise, and we need to keep trying and persevering! Only when we persevere, can we have real gains.

Basketball teaching: upper limb strength training, improve the power of shooting and dribbling, and it is not easy to lose the ball in confrontation.

If there is horizontal bar and parallel bar, it is best to do it, and it is most effective for the exercise of upper limb strength. Do pull-ups or parallel bars. If you don't have one, do push-ups, or barbells. Waist and abdominal strength is also very important, so do more sit-ups.

Are you asking if you have equipment or don't have it???
