Dynamic anthropometric data

Static and dynamic anthropometric data is collected by taking measurements fiom general or selected populations which resnlt in generally available tables to assist design. These are npdated from time to time.

An example of the important dynamic data for workplace design is range of joint mohUity (Table 3) which corresponds to postures illustrated in Figure 1. Very useful anthropometric data, both static and dynamic, are provided by the Humanscale (Henry Dreyfuss Associates 1981). When anthropometric requirements for the workplace are not met, biomechanical stresses, which may manifest themselves in postural discomfort, low back pain, and overexertion injury, are likely to occur (Grieve and Pheasant 1982). Inadequate anthropometric design can lead to machine safety hazards, loss of motion economy, and poor visibility. In other words, the consequences of anthropometric misfits may of be a biomechanical and perceptual nature, directly impacting worker safety, health, and plant productivity. 

Several individuals of varying body size, weight, shape, age, physical condition, attitude, aptitude, or mental ability may use workstations therefore, adjustability is necessary. The work environment should incorporate anthropometric designs to enable all workers to function within their capabilities and perform their job tasks optimally and comfortably (Braganza, 1994). Anthropometric data supply a standard guide of measurements, both static and dynamic, to provide an optimal dimensional layout of the workstation (Woodson and Conover, 1964). 

Dynamic anthropometry deals with the range of movement of people and also hnks with biomechanics when considering speed of movement in reaction to an event. Reach is an important aspect of dynamic anthropometry. Strength is an important aspect of biomechanics and varies more widely than anthropometric data, e.g. compare the strength of 18 and 79 year olds.
