METHOD OF MEASURING OF EJECT FORCE OF ELASTIC OBJECT BY RECOIL METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC G01P15/00 

FIELD: sports.

SUBSTANCE: invention relates to sports and may be used in making of elastic saddles inserted into sport shoes in order to obtain additional eject force. Device for measurement of eject force of elastic object consists of tube, installed on the analyzed object, with flanges and metal rods of different weight, welded to one of its ends, at top ends of which acceleration sensors are placed. When measuring eject force of flexible object, metal rods with different masses are placed inside the tube at fixed height from the object surface and released. Then acceleration of said rods is measured, and eject force of the analyzed elastic object is calculated by formula: F_kn = m_k·a_kn, where F_kn is specific eject force of elastic object on the n-th harmonic at k-th specific weight of the rod; m_k is k-th specific weight of the rod; a_kn is acceleration of specific k-th weight of the rod on the n-th harmonic.

EFFECT: technical result of invention is possibility of estimation of frequency characteristics of sportsmen's physical actions, as well as maximum eject force.
