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