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...
Outdoor breathing trials with simulated avalanche snow are fundamental for the research of the gas exchange under avalanche snow, which supports the development of the international resuscitation guidelines. However, these studies have to face numerous problems, including unstable weather and variable snow properties. This pilot study examines a mi...
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...
Terrain experiments for avalanche survival research require appropriate snow conditions, which may not be available year round. To prepare these experiments and test the protocol, it might be advantageous to test them in a laboratory with a snow model. The aim of the study was to find a material that can be used to simulate snow for studying gas ex...
Avalanche burials represent one of the most dangerous risks associated with winter activities in the mountains. Asphyxiation occurs as a consequence of blocked airways; or, due to a severe hypoxia and hypercapnia resulting from rebreathing previously exhaled gas. Recently, outdoor breathing experiments with healthy volunteers were conducted in orde...
Východiska: Rozdil mezi atmosferickým vzduchem a vodou lze popsat na zakladě chemických a fyzikalnich vlastnosti. Rozdil těchto vlastnosti ve vodě a na suchu prokazatelně ovlivňuje sportovni výkon a nelze stejnou cinnost vykonavat v obou prostředich totožně. Patrne je to zejmena u biomechaniky pohybu, kde důležitou roli hraje hustota prostředi. Kro...
Presence of an air pocket and its size play an important role in survival of victims buried in the avalanche snow. Even small air pockets facilitate breathing. We hypothesize that the size of the air pocket significantly affects the airflow resistance and work of breathing. The aims of the study are (1) to investigate the effect of the presence of...

This article focuses on airbag systems of backpacks as the only active avalanche device. It analyses current knowledge based on literature review. The goal is the summarization and clarification of this field on the basis of numerous surveys and case interpretations. In addition, it also focuses on current state of the on-market airbag systems. We...
Our article is focused on pathophysiology of snow avalanche death. It analyses available information based on literature search. The goal is the summarization and clarification, based on numerous researches and case interpretations, in the field of pathophysiology when buried under a snow avalanche. It is mainly focused on the hypercapnia and hypox...
This article analizes and compares transfers in winter conditions in selected NATO armies and armies cooperating with them. The target is to summarize information about the quality of training done in snow and ice. The article is mainly focused on security, realization, content, methodology of training and equipment used. We suppose that the inform...
