“…This corresponds to a work-specific energy demand of approximately 3.3 kcal/min. This is relevant because if our results are compared with the studies completed during the 1950’s and 1960’s (Max Planck Institute, Dortmund) [3–6], we find that the results are very similar. With the technical possibilities available at that time, they measured the average energy consumption for cleaning work to be approximately 4 kcal/min.…”

“…In order to gain better and more concrete information as well as numeric values for performance demands, studies on energy consumption in diverse professional sectors were carried out in the 1950s and 1960s [3–6]. Oxygen uptake (V’O2 in L/min) was determined as the central measured parameter, providing energy consumption (in kcal) via the caloric equivalent.…”

BackgroundThe aim of the study was to determine the physical effort and energy expenditure needed over a working period of 45–60 min, specifically for the occupational activity of cleaning. The effort was demonstrated in absolute terms (V’O2), in relation to the involved person’s maximum physical capacity (peak V’O2) and in relation to the individual aerobic-anaerobic threshold (V’O2 at VT1, the point when lactate starts to accumulate but can be cleared). In addition to this, the aim was to verify the suitability of portable ergospirometry in determining the occupational workload in a real-life setting.MethodsThirty-five cleaners performed a bicycle ergospirometry to determine their maximum physical capacity (peak V’O2 = L/min) and their aerobic-anaerobic threshold (V’O2 at the Ventilatory Threshold 1 [VT1]). This was followed by portable ergospirometry lasting 45–60 min while pursuing regular cleaning activities.ResultsPerformance V’O2 (the average oxygen consumption over 45–60 min of work- time) was 1.06 L/min or 4.4 METs. This was scarcely lower than the individual V’O2 at VT1 and approached 45% of the maximum physical capacity (peak V’O2). In addition, there was positive feedback regarding the wearability of the portable device. The dropout rate was low.ConclusionThe occupational activity of cleaning was defined as a “committed activity”, performed close to the upper limit of the continuous physical capacity (approaching V’O2 at VT1). The positive feedback and a low dropout rate proved good acceptance of portable ergospirometry in this field of work over a 45–60 min period.

“…Spitzer and Hettinger (1964), Garg et al (1978), and Genaidy & Ashfour (1987) have developed formulae for calculating energy expenditure, especially in manual material handling processes. Laurig (1982) has developed tables suitable for use in high physical workload situations based on the data of Lehmann, Müller, and Spitzer (1950) and Spitzer et al (1982). Both approaches may in many cases be suitable for incorporation into a computer-aided workload assessment and evaluation system.…”
