Изобретение относитс к спорту и может быть использовано дл определени результатов в спортивных сост зани х, предусматривающих норми- рованную структуру движени смортсме- нов на заданной дистанции, например, в спортивной ходьбе.The invention relates to sports and can be used to determine results in sports, providing a normalized pattern of movement of sportsmen at a given distance, for example, in walking.
Цель изобретени - повьшение точности и объективности контрол , The purpose of the invention is to increase the accuracy and objectivity of the control,
На чертеже изображены стадии фиксации техники спортивной ходьбы по предлагаемому способу.The drawing shows the stage of fixation of the technique of sports walking on the proposed method.
При постановке ноги 1 спортсмена 2 на спортивную дорожку 4 ее стопа 3 через узкую волос ную щель 5 проецируетс на носитель информации 6 .в виде параллельной направлению его перемещени линии 7 (лоз, 1), так как механизм взаимодействи стопы спортсмена с дорожкой (опорой) организован таким образом что стопа фиксируетс на опоре двум равными и противоположно направленными силами (опорным усилием спортсмена и реакцией опоры) горизонтальна скорость движени стопы на опоре равна нулю. Излом 8 линии 7 определ етс скоростью постановки стопы 3 на опору 4 Позици 2 по сн ет одноопорное поло- женив спортсмена на беговой дорожке, при котором положение стопы его ноги изображаетс в виде одной линии.When putting the foot 1 of the athlete 2 onto the sports track 4 of its foot 3 through the narrow hair slit 5 is projected onto the information carrier 6. Line 7 (vines, 1) parallel to the direction of its movement, as the mechanism of interaction of the athlete's foot with the track (support) organized in such a way that the foot is fixed on a support by two equal and oppositely directed forces (the supporting force of the athlete and the reaction of the supporting) the horizontal speed of the foot on the support is zero. The fracture 8 of line 7 is determined by the speed of setting foot 3 on support 4. Position 2 is replaced by the single-support position of the athlete on the treadmill, in which the position of the foot of his foot is depicted as one line.
На двухопорной стадии ходьбы на носителе информации фиксируетс две параллельные линии 7 и 9 (поз, 3). Общий участок 1 этих линий (поз, 4) с учетом скорости движени носител информации характеризует врем двух- опорного положени ног спортсмена, а длина 12 -каждого участка линий опреIn the two-step walking stage, two parallel lines 7 and 9 are fixed on the information carrier (position, 3). The total area 1 of these lines (poses, 4), taking into account the speed of movement of the information carrier, characterizes the time of the two-support position of the athlete's legs, and the length of the 12-each line segment is determined

дел ет врем одноопорного периода, соответственно, дл левой и правой ног.makes the time for the single support period, respectively, for the left and right legs.
В случае безопорного положени спортсмена в движении (переход на бег) на носителе информации будут наблюдатьс разрывы Ij (поз, 5), длина которых будет соответствовать времени фазы полета спортсмена.In the case of an unsupported position of the athlete in motion (transition to the run) on the information carrier, gaps Ij (pos. 5) will be observed, the length of which will correspond to the time of the phase of the athlete's flight.
Дл документальной регистрации спортсмена, техника ходьбы которого определ етс , при зафиксированном положении носител информации на него через вспомогательный объектив делаетс снимок изображени данного спортсмена.To document the athlete, whose walking technique is determined, with a fixed position of the information carrier on him, an image of the athlete is taken through the auxiliary lens.
Дл текущего оперативного контрол техники ходьбы судейска бригада (судь ) имеет возможность определ ть правильность техники ходьбы, наблюда за изображением двух точек, соответствующих нахождению стоп спортсмена на опоре, на полупрозрачном экране, например на матовом стекле, расположенном за волос ной щелью.For the current operational control of the walking technique, the referee team (judge) has the ability to determine the correctness of the walking technique, observing the image of two points corresponding to finding the athlete's feet on a support on a translucent screen, for example, on a frosted glass located behind the hair gap.
