Brief Summary
In order to reduce the physiological and biomechanical loads that the soldiers are exposed to, the investigators want to examine new approaches for distributing the carried loads according to measurements that are specific for each soldier (body composition and aerobic capacity). A functional index (LCI=load carriage index) will provide the commander a tool for better decisions in distributing the same total load among the same number of soldiers, according to each soldier's ability.

Study Arms (1)
research arm
EXPERIMENTAL50 subjects (healthy soldiers, male and female) from combat units will undergo the experiment protocol.
Interventions
the subjects will undergo the following experiment protocol: 1. recruitment and medical examination day. 2. physiological evaluation day- the subjects will perform twice\* a physiological stress protocol ; 3 min sitting followed by 20 min walking on treadmill (4 km/h, 4% slope), and then 3 min sitting for recovery examination. total 26 min. 3. biomechanical valuation day- the subjects will perform twice\* a biomechanical protocol using the Zebris system; 2 min standing followed by 10 min walking on treadmill (4 km/h, 4% slope). total 12 min. * once carrying the weight calculated according to the army current instructions, and a second time carrying weight calculated according to the new LCI. 2 hours rest between the two performances.
