METHOD FOR DETERMINING HEIGHT OF RISING ON TOES AND ANALYSING STRUCTURE OF UPWARD JUMP Russian patent published in 2024 - IPC A61B5/11 

FIELD: sport.

SUBSTANCE: invention relates to the field of physical culture and sports, is intended for analysis and objective control of the structure of an upward jump in order to determine parameters of lifting on toes in the repulsion phase – the most important controlled period of time for many types of human motor activity, including sportsmen in game sports. Disclosed is a method in which the boundaries of phases of an upward jump are determined from a dynamogram of a support reaction force. Introduction of the concept of two high-speed stages – acceleration and deceleration – in the phase of rising on toes, called the push-off phase, which is realized due to plantar flexion of the foot, enables to isolate the force pulse in the push-off phase from the full repulsion pulse. Further, the model height of the common centre of mass rise in the push-off phase is determined. Structure of the jump, determined during its analysis, enables to calculate the coefficient of efficiency of the jump – loss as the ratio of the actual height of the jump to its model – ideal value. With uniform distribution of losses in all phases of the jump, it is possible to calculate the actual height of rising on toes.

EFFECT: invention enables to obtain express information on the screen of the device for displaying information on the phase structure and height of the jump, on the height of rising on toes and the coefficient of efficiency of the jump, which is of interest for selecting players for teams in various sports; specified feature is of great importance for mass physical culture and involvement of wide range of population in sports, especially children, who need play attractiveness and possibility to compete.
