Sažetak
Loading and nonergonomical postures that a worker takes during his work effect his safety thus represent an injure hazard and permanent damage of the worker's organism. Intraabdominal pressure is used as a method for the judging of the biomechanical loading of the analysed subject. Two dimensional models in the sagital plane were used for the research, while is an assimmetrical posture of the worker in the space with the help of the three dimensional models in sagital and frontal plane. The intraabdominal pressure is directly connected with the lumbal moment. With the two dimensional model reduction of the worker's effort is achieved by introducing a more suitable direction of the resultant force in relation to the critical lumbosacral crossection. With the 3D models it is necessary to pay attention to the selection of the coordinate systems for the left and right shoulder ring to avoid reduction of the moments of the total lumbal moment so that the calculated intraabdominal pressure would be lower than the actual pressure.
