ABSTRACT:
Disclosed is an electronic ergometer placed in a housing and comprising a series arrangement of a transducer, for converting the oscillations of the body center of gravity of an individual into an electrical signal and implemented as a seismic pickup, and a pulse shaper having its output connected to an adjustable high-frequency multivibrator with a frequency adjusting means. A frequency divider is connected to the output of the high-frequency multivibrator, the output of the frequency divider being connected to the counting inputs of a first multi-digit counter and a second multi-digit counter. The outputs of the first counter are connected to inputs of an indicator. The control input and one of the reset inputs of the second counter are connected to an adjustable timer, whose reset input is connected to a time interval adjusting unit. The outputs of the second counter are connected to the inputs of a power indication permitting unit, the outputs of which are connected to inputs of the indicator. The reset inputs of the frequency divider and of the first counter and a second reset input of the second counter are connected to a zero setting unit. The control inputs of the indicator and of the power indication permitting unit are connected to an indicator switching unit.
