dc.description.abstract A field study was performed using 51 participants that were randomly selected from several Brazos Valley , Texas businesses to participate in an 8 -hour assessment of office seating habits that influence seating design and testing . A control group was established as those with BMI ?s < 35 and an obese group was established as those with BMI ?s >35 . Data was collected through written survey and through data logging of seat and back contact pressure (average and peak ) , surface area , center of gravity and duration of contact by recording 8 metrics , once per second using the X -sensor pressure mapping device and software . Additionally , 50 days of caster roll distance was recorded for the participants using a caster mounted digital encoder . It was determined that at alpha = 0 .05 , using the Student ?s T -test , a significant difference did exist between the groups in mean seat time per shift (p < .001 ) back contacts per shift (p < .002 ) , seat contacts per shift (p < .01 ) and caster distance rolled per shift (p < .001 ) . During a subsequent lab study , data were collected during 3 cycles of ingress , egress on the armrest use , along with anthropometry and critical chair testing parameters . Center of Gravity was measured from a fixed backrest (front to rear ) for 16 participants . 4 male and 4 female obese with BMI greater than 35 and 4 male and 4 female with BMI less than 30 were compared . The purpose of this study was to determine whether a significant difference existed between anthropometric factors for normal and obese participants that would affect how a chair should be loaded during testing . The null hypothesis that normal means and obese means for each measure were equal was rejected by using independent samples T -test at alpha = 0 .05 with p < .001 significance reported for all measures . These data suggest a need for a fresh look at several parameters used in the normal test standards as well as a need for a tougher test method for seating designed for the obese worker . en_US
