Overview of the Q-Force ӀӀ. A Performance of a maximal isometric knee extensor with the Q-Force ӀӀ; B Technical graph of the Q force with the dimensions; C White arrows (sliding directions of the force transducer) are perpendicular to the direction of produced knee extension force (orange arrow), preventing sliding of the force transducer during a measurement. Dotted white rectangle: Force transducer; White circle: wheels are attached at the side so that it can be transported; White squares: buttons to slide the force transducer upwards, sideward and forward making it possible to adjust the force transducer to the left and right leg and adapt is to different leg lengths of the participant; Dotted white square: Button to move the bar, which supports the heel, forward and backward
