Commercial airline cockpit crews flying transoceanic routes were tested repeatedly with a battery of cognitive tests implemented on a lap-top microcomputer. Testing was conducted before departure and during the early, middle, and late periods in flight on the outbound leg of four flight pairings. The same tests were administered on the return leg(s) of each flight pairing but, just prior to final administration of the tests, six minutes of moderate resistance exercise was undertaken by the Captain and one other pilot (either the First or Second Officer). The remaining officer substituted a walk around the aircraft cabin for exercise and served as a control. The same Flight Captain was available for testing on all flights (N = 22), but due to scheduling requirements, the same First and Second Officers were available for 4-8 flights each. Comparisons were made between the two exercise conditions over all test sessions, but no statistical relationships were found.

This paper presents the sample selection rationale and data collection methodology used to collect truck driver anthropometric and work space data. A total of 241 drivers were measured (183 males and 58 females). Data were collected in eight cities nationwide, based on estimates of the number of drivers in each geographic region. A mobile laboratory was used to measure, among other things, body dimensions, arm reach envelopes, foot reach, seat position, eye position, knee position, and stomach-to-wheel clearance. Three buck configurations were used which varied the number of parameters adjusted by the subjects, including seat fore-aft, seat height, steering wheel angle, steering wheel fore-aft, and steering wheel vertical positions. Front and side photographs were made of each subject in his or her preferred seating configuration.

This paper presents demographic and static anthropometric data collected from a nationwide sample of truck drivers. Demographic data presented include age, driving experience, and type of truck driven. Anthropometric results showed that the sample of truck drivers was taller and heavier than the general U.S. population. Twenty-one (21) anthropometric measures are reported for males (N = 183) and females (N = 53), including body lengths, breadths, and circumferences.
