The present disclosure refers to a multifunction device for the measurement of the strain on the faces of load cells and displacement on the free ends of load cells. This way, it is possible to measure the traction and/or compression force and energy expended by a muscle or muscle groups of the human body.The present disclosure allows also to determine the force profile, the instantaneous power and the average power.The present disclosure also relates to a device for the measurement, recording and digital monitoring of the evolution of force and respective expended energy.
