To get the maximal output of your exercise in gym machines, there are different factors to be considered. For example the strength of the muscle varies dependent on the position of the muscles. To get the best results of the exercise the load has to reduce and increase at specific positions. This study was made in cooperation with Caretaker Scandinavia AB, a company for sales, marketing and development in health care. They are general agent for Nordic Gym who works with manufacturing of equipment and machines for gym and fitness. The aim of this study was to generate a method of measurement to evaluate and control the biomechanics of Nordic Gym´s workout equipment. A protocol for an ergonomic analysis on the equipment has also been elaborated. One of the methods to measure the biomechanics was to measure the torque through the whole movement. The other method was electromyography (EMG). The EMGequipment registers electric signals that are generated in a working muscle, and makes it possible to see when the maximum muscle activity achieves. The results of those measurements will be compared to the muscles strengthprofile which describes how the muscle generates power in different positions throughout the movement. To measure the ergonomics an ergonomic protocol where produced, which was based on ergonomics aspect, adapted to gym machines. The method of measurement where tested on Nordic Gym´s training machine 101SE leg extension and Free Motion´s machine Leg Extension GZF18013 and this machines where controlled and evaluated. Two test persons tried out the machines and the machines where analysed in an ergonomic and a biomechanical perspective. The result shows that the biomechanics of Nordic Gym´s machine where a bit better than the biomechanics of FreeMotion´s machine. But in the both case the difference between the values of torque is marginal, to improve the biomechanics insistence a bigger different should be necessary to use. The ergonomic analyse of the machines showed that the ergonomics where good and well planed. Both machines had some small ergonomic lacks, which can be improved.
