1, decomposition straight slide exercise:
Stand by and squat. First, the body's center of gravity shifts to one leg, and the other leg pushes the ground obliquely backwards with the inside of the foot. After pushing the ground, quickly return to the static squatting position and slide freely. In this process, the upper body always keeps a static squat posture and cannot be changed. Then the center of gravity shifts to the other side, and the other leg pushes the ground, and repeats left and right. The main points are the same as above.
2, straight slide practice:
To solve the problem of straight-line sliding practice, you don't have to keep the static squat posture to slide freely when kicking your feet back to the static squat posture. Instead, one leg will be kicked out and the other leg will be kicked back immediately after you kick it back. In this way, the essentials and points of the center of gravity and posture are the same as those of the decomposition straight line sliding exercise.
3. Straight sliding swing arm action:
The purpose of adding swing arms in the process of sliding is the same as the principle of running and walking on land, both of which are to better maintain balance and achieve the purpose of steady acceleration.
Swing arm when sliding in a straight line: the two arms swing back and forth, and the swing height is that when swinging forward, the height of the hand does not exceed the face, preferably below the line of sight; When swinging backwards, put your hands under your body and swing up. Keep your arms straight, as close as possible to the inside of your body, and don't push too hard. Swing height is the free height of swinging backwards as far as possible.
Swing arm when cornering: When cornering, the arm on the inner side of the corner is naturally behind, and the arm on the outer side swings hard to keep balance. At this time, the amplitude of the swing arm can be slightly reduced.
Second, the curve slide
1, parallel turn:
Parallel turn is the basic turn of straight slide. The key points are: when entering the bend, the feet are parallel and staggered, the feet inside the bend are staggered forward, the feet outside the bend are staggered backward, and then the body center of gravity falls on the inside of the bend. At the same time, the longitudinal axis direction of the head and tail of the body should also be curved. Don't retract your feet until you come out of the corner.
2, bending:
When entering the bend, squat down and tilt your center of gravity to the inside of the bend. At the same time, the bent outer foot is pushed out to the outside, and then retracted to the front of the inner foot. At this point, your feet cross. When the outer leg retracts to the front of the inner leg, the inner leg should be pushed outward, so that after the outer leg retracts, the inner leg can be directly retracted and pushed out. After the inner leg is retracted, it should be placed below the center of gravity of the body to stabilize the center of gravity.
Third, stop:
When sliding forward, first put the center of gravity completely on one leg, and the knee of the leg is bent. At the same time, the other foot is raised horizontally behind the supporting foot, so that the toe angle of the two feet is 90 degrees, and then the back foot is used to gently mop the floor to slow down the sliding speed until the sliding stops. The center of gravity is always on the front leg, the upper body is always upright, the knee orientation of the rear leg should be consistent with the toe orientation of the rear foot, and the two knees should not be close together.

Safety measures before skating:
1, before practicing roller skating, you should first get ready for activities, especially the joints and ligaments of your wrists and lower limbs, and move fully.
2. Roller skating should wear some protective equipment, such as wrist pads, elbow pads, knee pads and helmets.
3. Before practice, check the fastening parts such as the screws of the roller skates to avoid injury caused by problems with the roller skates when sliding.
4. Beginners should practice in the beginner's school or within the prescribed scope, or try to practice in a place with few people, and don't skate at will. The first time you learn roller skating, it is best to have a skilled skating partner or psychological counselor for counseling.
5. It is forbidden to do actions that are dangerous or hinder others, especially in crowded public skating rinks, such as several people skating hand in hand, retrograde on the speed skating track or in the direction of skating with everyone, jumping around, jumping around in the court, chasing and flapping, and stopping suddenly. It not only hinders others, but also is prone to dangerous things.
6. When you want to fall forward or sideways, take the initiative to kneel down and hold the ground with your hands to reduce the power of falling; When you want to fall backwards, you should also take the initiative to kneel down, lower your center of gravity, try to let your hips sit down first, and pay attention to protecting your tailbone. Keep your head down at the same time to avoid falling backwards. When you fall, try to avoid holding the ground with straight arms and one hand, which is easy to damage your wrist.
7. People with serious diseases (such as heart disease and high blood pressure). ) It is not appropriate to participate in intense roller skating activities, and you can exercise slowly at most. In addition, people who drink alcohol and are overtired should not take part in roller skating activities.
