Abstract

This study describe the impact of 3 levels of physical protection on performance and load while accomplishing seven activities. Ten subjects participated. The equipment used was field uniform with combat vest (FU), weighing 19.0 kg; FU with body armour m/94 (FUK), 23.6 kg; FUK with additional ceramic plates (FUKP), 29.7 kg. The activities were climbing up and down a net; rifle shooting (AK5) at the distance 100 m and 200 m, without support, in a reclining position, when rested and after a 200 m dash; throwing hand-grenade from a reclining, kneeling and standing position; a 8x25m dash including kneeling fire position and turning every 25 m; belly-crawl through an 8 meter long tunnel; reach at various body positions. Altogether, FU was found best (lowest impact), better than FUK which was better than FUKP. However, the separate results did not always show this trend; There were no significant differences in hand-grenade throwing nor rifle shooting. In reach and belly-crawling the various equipments gave significantly different results. Furthermore FU and FUK were better than FUKP in dashing. Perceived exertion and body motion restriction followed the same trend as the combined performance data, e.g. the load and movement restriction from FUKP was worst and FUKP was best. Altogether, the results show that the best body armour impaired the performance and raised the load on the individual more than the lighter body armour which in turn was worse than wearing no body protection. The consequence in terms of fire power and own casualities can, however, not be estimated without further studies.
