Examining the humans work load and energy consumption allows us to identify the energy used for working postures and techniques and thereby create solutions how to make work technology and work environment better and altogether improve an employees work ability. There are several methods in which human energy consumption is determined by working postures, type of work and handling of loads, they all take account only the physical load factors ignoring mental or microclimate factors in the work environment. In recent times there are also used the mathematical models, in which the energy consumtion is determined on the basis of pulss frequency. The methods are complicated to realize them in the work situation because they do not allow to determine the dynamics of the work load in the work process. The aim of this research was to develop a method that enables to use a computer to determine and analyse the work process on screen at real time and that shows the employee’s heart rate, work load and energy consumption momentary load values as well as their dynamics. The method is based on continuous measuring the employees pulse rate in the working process without disturbing him and at the same time also filming work process to make a video to demonstrate the results. We introduce the methodology how to measure an employees pulse rate, work load and energy consumption dynamics to make a compiled video. There are shown the fragments of research results about a farmer’s and glassblower’s work.
