Abstract

The Armed Forces Physical Standard (FM FysS) includes Basic Requirements that apply to all personnel, and Additional Requirements, which apply to those military positions that include physical exercise more strenuous than normal office work. Basic Requirements, as well as Additional Requirements are supposed to focus on endurance and muscle strength. Running 2 km carrying 22 kg was chosen for testing endurance. To evaluate muscle strength, the results from 5 different tests were aggregated (push ups, sit ups, vertical jump, hanging in a bar with flexed arms, and the Sorensen test for spinal muscles). The reasons for that were (i) in the field the soldier is using arms, legs and trunk quite extensively, (ii) the strength in one muscle group is usually not very well correlated to strength in other muscle groups, (iii) the results from several tests on muscle strength taken together correlate rather well with the ability to perform physical activities in the field. Thirty six male conscripts performed two 2 km running test separated by at least one day with low level physical activity; one dressed in ordinary running gear, the other dressed in battle order (22 kg "skin out"). The time to finish differed on average 2 min and 58 s (7 min 57 s and 10 min 55 s respectively), while heart rate and perceived exertion were very similar. Running time for the two tests correlated quite well (r=0.88). The time difference between the tests was inversely related to body mass. To set the requirements for officers the principle that he/she should be able to keep up with the pace of their unit was adopted. Therefore conscripts (n=511) from 3 different regiments performed the 2 km running test dressed in battle order. The time (median) was 11min 27s. There was a marked performance difference between the different categories; the rangers were fastest (10 min 7 s). The Multi test was tried on conscripts (n=55) as well as on personnel recruited for international military service (n=78). The results form the different subtests were very weakly related to one another and to body size (stature and mass). The test-retest reliability was studied in 20 subjects. ICC was highest for the vertical jump (0.93) and lowest for Sorensen test (0.72); for all tests weighed together ICC equalled 0.86.
