What are the main points of double-board parallel skating?

When hanging (from top to bottom), Pueraria shook hands. Look at the board before you wear it, and lift the rear holder. Place the sole of the foot in the holder and press the heel on the back groove. You must have heard a bang. Snow boots are stuck in the mechanism. The fixing strength can be adjusted, and novices are easy to fall too tightly (3~4 is enough). Both sides of the pole help balance, and the feet move back and forth on the board. Don't worry when you get dressed, exercise before you practice. B. basic posture: the double boards are parallel to shoulder width, and the upper body is upright and slightly forward. The center of gravity sinks without weakness, and the knees are elastic to push forward. The abdomen is slightly raised, and the eyes are about 10 meter. Step on the snowboard and bear the weight with the forefoot of your foot. Hands waist-high, slightly abduction, shoulders relaxed, hands up. Smile, you will not be nervous, relax your nerves and tighten your muscles. Don't bend over and sit behind your hips, your calves are stiff and not propped up. C. basic seven practice one practice turning and walking, running from reverse to forward and sideways. The head and tail of the board should not cross, and the stride should be parallel to the small board. Don't struggle if you lose your balance, let it go, let it go. Second, turn back (180) and practice alternately from left to right. The front side of two crutches is supported, and the front lifting plate of the left leg is upright. The upper body, legs, and board turn left, and the board tip twists backward toward the back. When the board hits the ground, bear the load center, turn left on the right board and stand parallel. Practice falling and standing up to avoid the danger of collision. The two essentials of the fall action: the hips squat to one side and face down the slope to prevent rolling; Let it slide naturally and lift your feet, boards, arms and sticks. Three essentials to stand up: sitting on the snow side, the ground facing down, and the double board tucked under the hips; The double (mountain) blade is parallel to the snow sculpture surface, and the snowboard is perpendicular to the rolling line; Use your hands or poles as support, squat down first and then stand up. The four methods can slide on the snow, first walk and then gradually adapt. -When walking with two boards, lean forward and the two boards alternately press the snow; Lead the weight into a straight line, and the front bow extends back to the front knee; The snow pole moves with the arm, and the fulcrum is parallel to the foot center. -When the double board slides, the arm is extended forward and the front rod is supported backward; When closing the pole, lean forward, bend your knees, descend, and start the center of gravity; Lift one foot to practice the veneer, and slide forward with one (board) solid and one (board) imaginary. 5. Practice pushing the ice on the snow, with one foot off the board and one pedal. The tip of the board opens in a "V" shape (about 45), and the knee joint bends forward slightly. The center of gravity shifts to the pedal leg, and the vertical edge of the pedal turns the knee inward. The direction of pushing snow is vertical (vertical to the sliding direction), and the direction of leaving the board follows the center of gravity. Close the pedal quickly after pedaling, and don't touch the ground and stretch forward (out of the board); Slide your feet to the ground and then slide to the side pedal. The center of gravity should move quickly, and the body should move first, then push and then stretch. The weight plate moves back and forth, and the hips are forced to keep up with the body. All six practice slopes can stand well and remain stable. The double plate is perpendicular to the rolling line, and the upper outer (blade) and the lower inner (blade) are embedded in the mountain; The calf and knee press inward (on the snow surface), and the calf (on the thigh) leans against the virtual body (under the mountain); The upper body of the shoulder and hip rotates downward (mountain), and the inner edge of the lower plate bears the load. Practice going uphill, walking sideways and walking backwards. Five essentials of climbing a cross slope: the double board is perpendicular to the "rolling line" and the upper body vertical board is parallel; The lower inner (blade) is supported by the upper outer (blade), and the bearing centers are interchanged in turn; The lateral stride should not be large, and the poles on both sides should be balanced; The front ends of the feet are stressed and the knees are slightly bent forward; Knees and hips press up (mountain), waist and shoulders twist down (mountain). Three essentials of inverted splay slope: the body is facing the "rolling line", and the head is wide and the tail is narrow. The edge of knee inversion is upright, and the snow surface is embedded and squeezed outward; After the rod, stay in turn, and the double plates are pushed up alternately. D. slide down 1. Straight slide (two plates are parallel and slide straight along the "rolling line"). Adjust the strut, and the shoulder plate is parallel to the wide plate. Aim down at the "rolling line" and look up ahead. Press the front shell of the shin slightly, relax the upper body and lean forward. Relax your shoulders and arms, stretch your arms forward and bend your knees slightly. The two sides of the snow pole are naturally divided, and the forefoot of the two feet bears the heart. There are four common mistakes: squat down; The weight falls on the heel; Look down at the skis; These two boards are too wide and not parallel. Exercise: change posture from high, medium and low, and move the center of gravity back and forth. The inner blade and the outer blade look back and forth, sliding a board and lifting a board. The two boards walk sideways in turn, and the boards in the same direction are parallel. Skilled before jumping, practiced before leaving the snow. Grab the whole board and jump forward. Second, the eight-character downhill (also known as plow downhill. Refers to the technical action of the snowboard sliding straight down the mountain in a figure of eight. ) Eight-character deceleration and sliding control, seven essentials of technical movements: the tail of the snowboard is spread out at the same time, and the head is narrow and the tail is wide. Knees slightly flexed, slightly flexed, with the inner edge standing up and embedded in the snow; Control the strength by changing the blade, and push the heel forward; Slow down, stop with the same force, small eight slow down, big eight stop; Eyes look at the front and bottom, and the center of gravity falls between the two plates; Don't sit back on your hips, put your heart on the front and inside of your feet; Hold the crutch in your hand and put it on your hip. Relax your upper body and lean forward. E. Plow turn 1, figure-eight turn (also known as plow turn. Keep your skis in the shape of eight when you slide, and change the direction by moving your body's center of gravity to a side plate or increasing the snow pushing force of the skis on one side. ) when the figure of eight slides straight down, the center of gravity moves quickly to one leg. The bearing side of the inner blade presses down, and the pressing body is pushed out by applying force. The body posture cannot be changed, and the floating legs remain splayed. The two (inner) blades press the center of gravity in turn, and the sliding route is S-shaped. Second, the half-word turn (one board is a splayed downhill board and the other board is a straight downhill board). One board is tall and straight, and the eight-character board is load-bearing. Stand upright, press, push and stretch, and keep parallel when the floating board is closed. Third, the semi-figure-eight continuous swivel (in the middle of the left and right semi-figure-eight swivel, a transitional sliding stage of parallel sliding of double plates is added), and parallel sliding of double plates is added between the left and right semi-figures. According to the different skis, there are two ways to turn. The two methods are practiced alternately, and the rhythm is changed first slowly and then quickly: 1. The side plate on the mountain rotates continuously (pushed out by the turning outer plate) to maintain the semi-rotation potential, and the side plate on the mountain (left) pushes outward. Push to form a half figure at the same time, turn your knees and press your body upright. After pedaling, the body relaxes and the center of gravity moves back while pedaling. The two plates slide in parallel and obliquely, and slide into the vertical "rolling line". The inner edge of the outer (right) plate is connected with the weight, and the left leg recovery plate is parallel. 2. The downhill side plate turns continuously (pushed out by the turning inner side plate). After the last turn, most of the weight is on the left (downhill) board. The inner edge of the left disk is carved with snow, and half of it is pushed downward. Push (the board) to the right, lift the board, and restore the outer edge. The right plate slides horizontally forward, and the left plate bears the weight when it is closed; At the same time, the inner edge of the bearing bracket is used as an auxiliary adjustment rotation. When turning, your knees bend forward and your center of gravity drops slightly. After turning, slide down to the left (the two boards are parallel), and the right (downhill) board bears most of the load. There are six common mistakes in half-day continuous turning: stepping out, slipping and biting; Hips, shoulders and upper body should not face down (mountain); The snow pole is far away from the body; Excessive outward pressure on the upper body; The moving pedal is uncoordinated; There is a lot of ups and downs at the corner. F. Sloping downhill (sliding diagonally across the slope with a straight line). The knees of the two boards are slightly bent, and the knees and ankles are tilted outward (uphill). The shoulders and hips twist down the hill, and the body shape turns the bow (
