There is still lacking a standardized tool for the examination of working potential of the individual in physical area in the Czech Republic. The methods used cover the problem only in part, not being sufficiently precise and valid at the same time. In the world practice there are various tools for this purpose. Special position among them is held by tests performed in the laboratory environment, evaluating individual physical components of the working process – FCE (Functional Capacity Evaluation) in the analytical way. Following an analysis the authors selected (in their opinion) the most suitable method – Insernhagen WS FCE – for the validation and application in our conditions. The paper provides a detailed description of the methods (in respecting copyright) and additional tests making the diagnostics more precise.
