Abstract
Energy uti Iisatiou at V~)I"ki11 tile labour-i ntensi ve bui leiing industry is of prim
importance to contractors who match people to jobs. This paper provides an insight into
modelling energy expenditure ill a specific task, namely brick laying in various
postures. It therefore lakes previous "generic" biomechanical-energy prediction models,
and makes the case Ior apply: Ilg and adapting broader theoretical models to a specific
occupational task. This refinement of established models provides a meaningful and
valuable contribution to interpreting and predicting energy expenditure during a defined
occupational task - brick laying. Results obtained show that in the standing position,
fewer muscles are brought into action. For the silting position, the muscles are more
relaxed, relieving the bricklayer of stress, but the center of gravity is still lower than the
standing position. III the case 0" squatting, there is a lot of strain in the body by
considering the muscles or the arms, legs, and back resulting in more energy released ill
the body. The bending position has repeated movement of the muscles at the back and
the center of gravity varies. Thus, this research on energy expenditure in brick layers
may be of interest to ergonomists and those interested in biornechanical-cnergy
modelling.
