Description

METHOD FOR TRAINING IN ALPINE SKI AND SNOWBOARD AND DEVICE FOR IMPLEMENTING THE METHOD

The invention can be used in the process of initial training in skiing and snowboarding, in particular, for training in speed control and performing carving (cut) turns.

The traditional method of teaching skiing is well-known and widely used, in which at the first (intermediate) stage a confident safe stay on the slope is generated, during which the student is on the descent in the stop position ("plow"), and at the second stage, the actual carving riding technique. The first stage involves finding the skis in the “socks together - heels apart” position, the body shell in the rear rack, in which the learner’s center of gravity is shifted back from the perpendicular held to the ski through the center of the boot. To move along the slope, the learner reduces the angle - the distance between the heels of the skis, and to complete the rotation transfers the center of gravity to the left or right leg. As a device for implementing such a technique, ski poles are often used, the ends of which are held by the trainee, and the second is the trainee, located below the trainee on the slope and controlling the position of the trainee with sticks.

The main drawback of such a technique is the accumulation of muscle memory of an incorrect body position and turning, as a result of which the trainee develops a back stance and yudshagivaniya "during a turn, requiring, in the future, a significant amount of time and effort to retrain and develop the carving (cut) technique turns. The described disadvantages are caused by the fact that when riding with a “plow”, the position of the student’s body in its biomechanics is fundamentally different from the main skier stand, in which (carving) rotation. So, when making a turn when riding with a “plow”, an alternate transfer of body weight occurs, in which initially the main part of the load is perceived by the external ski (from the center of rotation) throughout the turn, and to make the turn to the other side, the weight of the body must be transferred to the second ski and simultaneous raising of the foot for “podschagivaniya" external ski, while the carving turn occurs on both parallel-directed skis throughout the turn. In addition, the use of ski poles in the learning process causes a shift in the learner’s center of mass back (dump to the rear rack), and also carries the risk of injury from the sharp end of the stick.

As the closest analogue of the claimed solutions, a method of teaching children alpine skiing, described on the website http://www.applerise.com/merchart, can be proposed

ARS & Product_Code = l 404-LESH & Category_Code =, which assumes the use of a ski toe lock for their stable position in the form of a wedge or plow while simultaneously placing a belt with fastened slings on the belt of the student, by which the student, by pulling the left or right of the slings, helps the learner enter the turning mode .

Among the main disadvantages of this method should also include the accumulation of muscle memory of the incorrect body position and turn, resulting in the formation of the back stance and step-up during the turn - during training, the student is in the back stance, and the skis in the stop position (“plow”) . In addition, a high belt fastening on the body contributes to the dump in the rear rack - above the center of the axis of flexion of the hip joints, which also prevents the body from tilting forward, and the device in the form of a waist belt contributes to scrolling it on the body and, as a result, does not provide an accurate transfer of effort to the hip joints from the side of the student.

The problem to be solved when creating the claimed solutions consists in the possibility of learning the technique of skiing and snowboarding for mastering the carving (cut) turn from the first lessons, in which the student immediately acquires the skills of the technique of such a turn, minimizing the need for preliminary physical and theoretical training, the technical result achieved in solving the problem is to increase the safety of skiing or snowboarding, as well as improving safety and efficiency spine of the learning process, through continuous monitoring of the training of speed and movements trainee.

To achieve the result, the claimed method of teaching turns on skiing or snowboarding is proposed, including the location of the learner above the learner on the slope, their descent and control during the descent of the learner over the learner’s speed and movements of the learner’s turn by pulling the right and / or left control lines connected to the attachment points on the device for learning to turn in the form of a belt, fixed on the student’s body in the area of the hip joints.

Preferred, but not mandatory options for the implementation of the method involve fixing the training device on the student’s body in the area of the hip joints by means of leg girths connected to the belt, as well as the fact that the learner’s speed and location on the slope by means of control lines are used to develop the carving turning technique.

To achieve the result, it is proposed a device for teaching turns in alpine skiing or snowboarding, containing a belt and control lines connected to the device, in addition to provide leg girths connected to the belt through the front and back supports and employees to fix the device in the learner's hip joints.

An embodiment of the device involves connecting the control lines to either the leg girths or the front and back support of the leg girths, as well as the belt, leg girths and back supports in the form of belts with quick-release buckles.

The invention is illustrated by schematic diagrams showing the position of the learner and learner, their interaction principle and the location of the device on the learner’s body when training in alpine skiing - Fig. 1, snowboard - Fig. 2, and also a device variant (belt and leg girths) - Fig. .

The ability to achieve the set result through the claimed group of decisions is due to the following.

In general, skiing or snowboarding is reduced to the repetition of two complex coordination movements - “turn right” and “turn left”. Turning is the main element of skiing and snowboarding equipment and is used to control speed, hillside location and braking. Of the existing methods for the interaction of ski skis with snow during a turn, the most effective from the point of view of speed and skiing techniques is carving (cut) gliding, in which the ski or snowboard set on the edge bends and writes out a cut turn. Thus, the effectiveness and safety of skiing are directly dependent on mastering the technique of such a turn and developing and mastering the relevant skills. The claimed group of solutions allows the latter to be fully implemented, since the place of fixation of the device for learning the bends according to the invention is the area of the hip joint, together with the tension of the slings allows you to most accurately adjust the biomechanical position of the body when learning the turns on skiing and snowboarding. So, with skiers, when training one of the lines, the student’s body twists, his knees are slightly shifted towards the turn, the body weight is transferred to the outer and, accordingly, the inner rib of the feet, and the skis stand on the edge, the projectile bends and the turn takes place. Accordingly, with snowboarders, when pulling one of the lines, the body twists, the student’s knees bend a little, the body weight is transferred to the socks or heels (for right or left turn), while the snowboard rises to the front or rear edging, the shell bends and the turn occurs . The consequence of such training is that the student from the first lessons learns the complex coordination technique of carving (cut) turning without complicated, preliminary physical and theoretical preparations.

The general sequence of actions during the implementation of the method is that the student is located behind (on the top of the slope) and controls the learner's movements by means of stretched lines, while the learner is in the front stance (knees are slightly bent, the body is tilted forward, hands in front are slightly bent at the elbows) . Sports equipment (skiing or snowboarding) is located with socks (or nose down). The teacher starts a slow movement together with the student down the slope, when making a turn, the teacher pulls up the corresponding (right or left) control line, as a result of which a carving turn occurs (see the description of the technique above). Depending on the training mode (skiing or snowboarding), the control lines are attached to the attachment points (Fig. 1) located on the leg girths for skiing, or to the attachment points (Fig. 2) on the front and rear supports of the leg girths - for the snowboard. Among the additional advantages of the method that increases its safety, it can be mentioned that the speed of movement and the location of the trainee on the side of the mountain are always under the control of the trainee. AT Among the additional advantages of the training device, the possibility of easily and quickly putting it on / off can be mentioned, due to the applied quick-release self-reset buckles located on the belt, leg girths and back support of leg girths.

A design variant of the device for implementing the method is shown in Fig. 3, where poses 1-4 show the attachment points of the control lines (1 and 2 - for learning how to turn on alpine skiing, 3 and 4 - for learning how to turn on a snowboard, respectively), self-reset buckles - 5, 6 on the belt, 7, 8 on the leg belts, 9 - on the back support of the leg belts, pos. 10 - back support of leg belts.

Summing up, the claimed group of inventions allows you to teach turns in skiing and snowboarding, achieving a positive effect, reducing the training time necessary for mastering the difficult coordination technique of carving (cut) turning and maximally protect human life and health when learning downhill skiing and snowboarding.
