1. Slide in a straight line

The straight skating posture is the basic technique of speed skating. The reasonable gliding posture should be: the upper body is relaxed and leans forward, the natural mass is parallel to the ice or slightly higher than the arms, the legs are deeply bent, the knee joint is at an angle of 90 ~110, the ankle joint is at an angle of 50 ~ 70, the arms are relaxed behind the back, and the head is slightly raised. Sliding posture should be based on personal physique, sliding distance, skating rink conditions, weather conditions and other characteristics. The key to straight skating is to grasp the appropriate time to push the ice. Ice skates cut into the ice in order to get a stable fulcrum, and at the same time, they should start pushing the ice, and the maximum force should be completed at the moment when the legs hand over the weight. In order to use heavy objects to push the ice, the heavy objects should be firmly pressed on the support legs when dumping, and the heavy objects should not be handed over prematurely. In the leg retraction, you should use the elasticity after kicking the ice to immediately relax your hind legs and actively move closer to support your legs. There should be no pause or retreat. Pay attention to the leading position of the knee joint when cutting, which is consistent with the direction of advancement. Pull forward quickly and move gently after touching the ice.

Step 2 slide in the corner

The basic posture is similar to straight skating, but due to centripetal force, the movements of turning and straight skating are very different. When sliding in a curve, the body always leans to the left, and pushes the ice with the outer edge of the left foot and the inner edge of the right foot. The inertia taxiing stage in curve taxiing is very short, especially for the right foot, and there is almost no inertia taxiing stage in short distance taxiing. The main action requirement is that the last 1 step of the right foot should enter the junction of the straight and the curve when entering the curve, and the depth depends on the weather, ice, wind direction and project. The left leg is close to the right foot and points in the tangential direction. When it comes into contact with ice, toes begin to eat gradually. Bite the ice tightly with the outer edge, and the left shoulder is in the same direction as the new tangent. Don't twist your waist and hips. After kicking the ice, relax the leg retraction action, actively pull in the direction of supporting the leg, and take the knee joint as the leading factor to form the front bow angle. In the process of recovering the floating leg, push the body to fall to the left and push the leg while recovering. In the direction of kicking ice, the feet should have the feeling of "pushing sideways", and the longitudinal axis of the upper body is consistent with the direction in which the floating feet touch the ice.

3. Startup technology

There are mainly two kinds: one is the front and front foot ice starting method, and the other is the side starting method. Elite athletes often use 1 method. Its main action is from a static state, using reasonable technology, quickly transformed into a fast sliding technical action. The starting technique is particularly important to improve the performance of short and medium distance events. The technical point of front foot icing is that the toe of front foot is the fulcrum and the back foot is covered with ice. The distance between the two knives is slightly wider than the shoulder and faces forward. The squat posture is slightly higher than other starting postures, and the center of gravity is between the feet or slightly in front. When starting, lift your thighs high and lean forward. When the skates touch the ice, cut the ice tightly and don't slip in the first few steps.

4. Swing arm action

Mainly used for short-distance skating, it can coordinate and increase the power of pushing ice. More and more people use single-arm swing in long-distance sliding. The swing arm has less force and the swing direction should be consistent with the sliding direction. No matter whether you use double swing arm or single swing arm in short or medium distance, you should exert your strength, especially pay attention to the speed and strength of side swing and front swing.
