Overuse injuries are responsible for most lost training days and attrition from combat training in the Israeli Defense Forces (IDF) as in armies around the world. The purpose of this study is to understand the rates, types, and mechanism of occurrence of overuse injuries in the IDF in order to provide the IDF's commanders a detailed updated situation report in order to enable commanders decision-making, prevention policy, and further research of this highly significant military public health issue. Methods: A cross-sectional study including 20,000 soldiers recruited to combat units during the year of 2013 was performed. Most of the data were collected from the IDF's computerized medical consultation records package. Descriptive statistics (percent, mean, standard deviation, and median) were used in order to express results. The study was approved by the IDF's institutional review board.
