Abstract This paper reports 2 baseline studies and one experiment performed in a confined-space military vehicle concerning the effects on fitness and performance of time in a sitting posture and workstation characteristics. On average physical fitness decreased by slightly more than 10\% per hour, the observation performance decreased by 30\% per hour, and the technical performance (of gunners) showed a relatively small decrease, i.e., less than 5\% per hour. So-called active breaks (changing sitting into standing and walking) led to a significant reduction in the decrease of physical fitness, almost reducing it to zero. Furthermore, the level of confinement was shown to affect physical fitness.
