FIELD: sports.SUBSTANCE: movement with the above travelpath with ski poles is achieved in that the rods of the poles in the support elements and pikes are provided with the locking resilient-elastic devices with the ability of avoiding the interaction of the support elements of the poles and the pikes with the track at the dragging the poles on the track after the push, at that the resilient-elastic devices are made with the ability of unseparated sliding when dragging on the track, regulating and fixing them in length of the rods, and the surfaces of the elastic device in contact with the track are made with a small coefficient of sliding friction.EFFECT: increased efficiency of ski poles by using resilient-elastic devices which enable to reduce significantly the load on the arms and upper shoulder girdle of the user, the poles are made with the ability to use them during the passage of the distance with all the known skiing and skating techniques of movement.8 dwg |
