      <subfield code="a">No clear definition of posture can be found in ergonomics literature. It may be regarded as the configuration of the body's head, trunk and limbs in space or as a quasistatic biomechanical alignment, depending on whether the particular context in which it is used is anatomical or biomechanical. An analysis is also made of the factors involved in the exertion of force, including physiological, environmental, personal, and task factors, in order to give a better understanding of the influences of task and workplace on strength capability</subfield>
