Auxiliary Device to Alleviate Soldiers' Backload

Not Applicable
Conditions
Physiological Strain of Weight Bearing.
Registration Number
NCT01565876
Lead Sponsor
Medical Corps, Israel Defense Force
Brief Summary

Combat soldiers are required to perform under strenuous physical conditions; hence, their physical fitness is a crucial factor in their survivability.

The Auxiliary Device- "Minkal", is suggested (by its manufactures) to be able to reduce the soldiers' physiological strain by lowering the absolute load being carried by the soldier. As a result, it may improve the soldier's physiological abilities and performance through enduring missions with heavy loads, and may lead to better protection on the soldier from overuse injuries.

Study & Design

SINGLE_GROUP
Primary Outcome Measures
NameTimeMethod
Physiological Load with and without the auxiliary device6 days for each patient.

The physiological load will be measured using a heat tolerance test(HTT). Each paricipant will undergo a HTT 5 times (in different days). first day- without load. second day- with back load of 40% of the body weight. third day- with back load of 40% of the body weight and the Auxilairy Device. fourth day- with back load of 60% of the body weight. fifth day- with back load of 60% of the body weight and the Auxilairy Device. The rectal temperature, skin teperature and heart rate will be mesured in each HTT and compered afterwards to assess the physiological load.

Secondary Outcome Measures
NameTimeMethod
Rectal temperature6 days

The Rectal temperature will be mesured by a rectal thermistore during each HTT.

Skin temperature6 days

The Skin temperature will be mesured by skin thermistores on three sites (chest, leg and arm).

Heart Rate6 days

Heart rate will be monitored using a polar watch.

Sweat Rate6 days

Sweat rate will be calculated from the patient's weight and his water balance.
