Basically pre-stretching determines a greater activation of the central nervous system allowing to optimise the training methodology (Bosco and Viitasalo, Electromyogr. Clin Neurophysiol 22, 1982; Forest, in: Biomechanics XB, 1987).

From an application point of view from these studies originates the battery of tests known as Bosco Tests used today all over the world. At the beginning of the eighties Bosco invents and patents two innovative systems for physical evaluation known as Ergo Jump™ and Ergo Power™ that in a simple and not invasive manner allow the measurement of power output and muscular work during physical exercises of different nature.

In the following years these two products have been integrated in a new version known as Muscle LAB™ that includes synchronised electromyography making possible the study of the electric answer of working muscles. In the years these products became precious instruments for many physiologists, coaches and athletes optimising physical testing, the planning of training and the prevention of injuries.
