N2 - This work aimed to determine loads exerted on the muscular and skeletal system in the segment of the lumbar spine during the execution of everyday activities, such as sitting down and getting up from a chair as well as lifting a 10 kg object off the table of various heights – 50 and 72 cm. Simulations were made by means of a dynamic mathematical model of the human motor system – GaitFullModel developed in the AnyBody Modeling System. Values of reaction forces in intervertebral joints and selected muscular forces in the lumbar segment of the spine were determined by solving an inverse dynamics problem. It was achieved by using methods of static optimization which adopted a criterion of minimization of the sum of the cubes of the relation of muscular force to its maximum force. The obtained results were standardized according to the body weight(BW) of the examined person. The highest values of loads were obtained in segment L5-S1: 2.7±0.16N/BW for sitting down, 1.77±0.22N/BW – getting up from the chair, 4.11±0.22N/BW – object lifting from a height of 50 cm and 2.68±0.11N/BW – object lifting from a height of 72cm.
