APPARATUS FOR EXERCISING OF SPRINTERS AND FOOTBALL PLAYERS Russian patent published in 2007 - IPC A63B21/65 

FIELD: training of sportsmen, in particular, teaching of start and motive actions at initial portion of starting stride.

SUBSTANCE: apparatus has power block, measurement unit, and program unit. Power block consists of peripheral sensors and is made in the form of variable loading resistor having belt to be put on by sportsman during exercising and connected to one end of inextensible cable running around pulley mechanically connected with first strain gage sensor. Second end and the entire cable are wound onto drum rigidly joined to copper disk, with both being put onto single rotating pin. Part of copper disk is embraced with electromagnets connected through first amplifier and switch to output of base unit of personal computer or to adjustable output of power source. Measurement unit has copper disk motion sensor connected through first analog-to-digital converter to base unit of personal computer, first strain gage sensor connected with its power input through pulley to cable and with measurement output through second amplifier and second analog-to-digital converter to input of base unit of personal computer, angular measurement unit to be put onto sportsman's knee joint and connected through third analog-to-digital converter to input of base unit of personal computer, first start shoe with built-in second strain gage sensor which is connected with its measurement output to input of base unit through third amplifier and fourth analog-to-digital converter, and second start shoe with third built-in strain gage sensor which is connected with its measurement output to input of base unit of personal computer through forth amplifier and fifth analog-to-digital converter. Program unit includes retrieval, mathematical and service programs.

EFFECT: provision for investigation of biomechanical mechanism of functioning of sportsman's muscles at start and start stride portion, increased efficiency of motion actions through employment of technical means facilitating in development of force and speed.
