Abstract [sv]

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.
