Difficulty in evaluating the amount of activity in which highly specialised military units are engaged has prevented the implementation of a strict training programme designed to minimise overuse injuries.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Purpose<\/jats:title>\n                  <jats:p>To quantify the ambulatory physical activity performed by trainees during the initial training phase in a Naval Commando Unit, with a view to developing more exact physical performance guidelines for the unit and the Israel Defense Forces, in general.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Twenty-four accelerometers were worn by two teams each day. Trainees were instructed to wear the device on their non-dominant wrist 24\u2005h a day, during all types of activities. Twice a week, the devices were collected, checked for damage and recharged, and the data were transferred to a computer.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Six trainees failed to complete the 9-week training period. Of the total 1512 accelerometer-days, 1075 readings (71%) were included in the study data. Trainees ambulated on average a distance of 15.5\u00b18.61\u2005km\/day and 95.5\u2005km\/week. Accelerometer readings (estimated distances) were averaged each week for the two teams. The total distance measured over the 9-week study period was 911.15\u2005km in team A and 808.38\u2005km in team B. The total distance measured in both teams was, thus, almost double the planned 440\u2005km (p=0.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Trainees greatly exceeded the planned safe distance.
