Content	Problem Labour-saving devices and the widespread use of computers have led to low levels of physical activity at large number of workplaces. Since physical inactivity and static body postures are associated with serious health risks, many companies are taking measures to promote physical activity. Objective and valid recording methods are required in order for physical activity at the work- place to be quantified and for the efficacy of the relevant influencing measures to be evaluated. Activities The CUELA activity system was developed for precise quantification of physical activity by work- ers. It consists of an instrument worn on the body which records body movements detected by sen- sors. Movements of the torso, legs and dominant arm are recorded by a combination of acceleration and angular velocity sensors. The miniature sensors are attached beneath the clothing by means of elastic and breathable straps. The measured data are recorded in a memory unit worn over the clothing, and can be evaluated subsequently on a PC by means of the associated software. Use of the CUELA activity system at an office workplace Pattern detection algorithms are used by the soft- ware to identify body postures and tasks automati- cally. The intensity of movement is determined both for specific body regions and for the whole body. The activity type and intensity of movement and the personal data recorded beforehand are used to estimate the energy expenditure. Statistics are also generated automatically on the type, intensity, duration and frequency of physical activ- ity and body postures. In order for estimation of the energy expenditure in the CUELA activity system to be calibrated and subsequently validated, two studies were con- ducted, with mobile breathing measurements being performed synchronously (ergospirometry). The automatic activity detection was verified by means of simultaneous video recordings. CUELA activity system for analysis of physical activity 0311 Edition 2/2013 617.0-IFA:617.81
