Introduction: The article is focused on description and comparison of the selected friction knots manners during static load. Aim of Study: The main objectives of the study are to find the proper values and standard manners of five friction knots used in military climbing, rescue techniques, arboriculture and mountaineering. How strong is the syste...

Introduction A lack of sleep can pose a risk during military operations due to the associated decreases in physical and cognitive performance. However, fast-acting ergogenic aids, such as ammonia inhalants (AI), may temporarily mitigate those adverse effects of total sleep deprivation (TSD). Therefore, the present study aimed to investigate the acu...

Tactical operations and armed conflicts involve symmetrical and asymmetrical conflicts, often occurring in urban and constantly changing environments. This requires tactical personnel to be prepared for unpredictable threats in dynamic scenarios. In close-quarter situations, short weapons such as handguns are becoming increasingly prevalent over as...

The aim of this study was to find the effect of holographic sight (HS) on short-distance shooting accuracy and precision during static and high-intensity dynamic actions. Twenty policemen (31 ± 2.2 years, 85.6 ± 6.1 kg, and 181.9 ± 4.4 cm) performed five shots in the 10-s limit under the static condition for 20 m and dynamic condition 15–5 m, and a...

Fatigue is common clinical issue, where previous effort, whether physical or mental leads to a reduction in the ability to perform activities. Fatigue severely affects human performance and error rate. Recently, in addition to researching physical fatigue, great emphasis has been placed on research into mental fatigue. The relationship between the...
