“ It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them. ”

Fernandez, Jeffrey E., Pitetti, Kenneth H., Stubbs, Nancy B., Marley, Robert J. and Cihangirli, Mihriban (1988): A Comparison of Equations and Methods for Determining Percentage Body Fat. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 558-562.

“An experiment was conducted to assess the differences between various equations and devices for estimating body fat percentage. Valid estimation of body fat is an important variable in determining the individual differences in energy expenditure or physical work capacities of workers performing various tasks. Twenty male volunteers participated in this study. Results indicate that no significant differences exist between device type. However, there were significant differences between derived estimations of body fat content with several widely used equations. These results were also related to estimation of body fat content derived from the bioelectrical impedance procedure. Results from this study indicate the need for comparison between subject population and population of prediction models before determining body fat and possible use of an average of several equations.”

Fernandez, Jeffrey E., Marley, Robert J. and Stubbs, Nancy B. (1987): Lifting Physical Work Capacity as a Function of Frequency. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 1331-1335.

“A laboratory experiment using 15 male subjects was conducted to document lifting physical work capacity over the frequency range of 2 to 12 lifts per minute and to compare these values to bicycling physical work capacity. Results indicate that bicycling PWC is significantly higher than lifting PWC at the 0.05 level. A variation in lifting PWC as a function of frequency was observed. This could be attributed to lifting technique. Task design should, therefore, not only consider lifting PWC but also the frequency of lift.”
