Evaluation of direct indicators of physical performance in servicemen via simulation of typical elements of the military-professional activities

Relevance. Servicemen wearing body armor (BA) have reduced physical performance as well as quantitative and qualitative indices of training and combat activities. Objective. To assess the influence of modern body armor on direct indicators in servicemen performing standard elements of military professional activity. Methodology. 195 volunteers from motorized rifle units and parachute units equipped with modern body armor were examined. Direct indicators of physical performance were assessed during military-professional activity: 5 km quick march and obstacle course. Exercise time was documented along with specific obstacle elements servicemen could not overcome. Results and Discussion. The research has shown that greater body armor weights disturbed the quality and ability to overcome obstacles typical for combined-arms battle. This weight is undoubtedly one of the most important medical and technical characteristics and should be considered in relation to the body weight of servicemen (SM) to derive the (mBA/mSM) ratio and assess influence on direct indicators of physical performance. Conclusion. Modern trends in body armor development include increased area and protection level; this is associated with increased physical load and lower effectiveness, thus creating additional risks of exposure to enemy fire.
