Use of Virtual Reality Technology for Training Standing Shooting, Postural Balance, and Rifle Stability in Biathlon: A Pilot Study
Psychology. Journal of the Higher School of Economics. 2025. Vol. 22. No. 3. P. 434–448.
Success in biathlon depends on physical fitness, psychophysiological parameters, and biomechanics. Key aspects include the speed and accuracy of shooting, which affect body oscillations and the stability of the "body-rifle" system. The level of stress, environmental conditions, and ski preparation are also important. This study is aimed to provide a thorough theoretical analysis of the factors affecting the standing shooting performance in biathlon, and to conduct a pilot study using VR to validate it as a training tool based on the observed parameters. This study utilized the Biathlon-2024 Virtual Environment, which simulated skiing and standing shooting in classical biathlon. This Virtual Environment is developed on Unity 3D platform and includes two stages: 1) VR skiing, 2) shooting. Subjects performed shooting at virtual targets, whereby the VR visualization fully simulated a biathlon shooting range. The results confirmed that stability of bodyrifle system is crucial for successful shooting in biathlon. It was observed that elite athletes demonstrate a better postural balance and a lower sway compared to beginners. The data analysis obtained with Antilatency system trackers showed a distinct correlation between the limb and rifle positions, which highlights the importance of a fine postural control and reaction time when shooting. The study emphasizes that success in biathlon depends not only on physical fitness and shooting techniques, but also on environment, psychophysiology, and individual attributes such as tremor. This therefore makes an integrated approach to athlete training essential for high performance.

Musical training has a significant impact on brain organization, leading to functional and structural
adaptations that enhance auditory, visual, motor, and cognitive processes. This study investigates how
extensive musical training shapes functional brain connectivity by comparing professional musicians and
non-musicians. Using EEG phase-locking value (PLV) analysis, we examined neural synchronization across
alpha, beta, and gamma frequency ranges during music ...

Knowledge graphs are widely used in Retrieval Augmented Generation (RAG) and Explainable AI (XAI), since they can illustrate semantic relationships generated by Large Language Models (LLMs). Recent studies focus on generating knowledge graphs from unstructured data to improve RAG performance; however, they do not explain the underlying graph structure. The analysis of synthetic graphs behind ...

Abstract
Context and relevance. In the context of accelerated urbanization and a growing disconnect from the natural
environment, there is increasing interest in biophilic attitudes — a system of stable views, beliefs, and
evaluations that reflect a person’s relationship with living nature and shape their psychological well-being and
environmentally responsible behavior. Existing tools for their measurement, such as the ...

Reinforcement learning (RL) is increasingly grounded in tools from probability, optimization, and operator theory. This survey organizes the mathematical structures that underpin the design and analysis of modern algorithms in RL. We begin from Markov decision processes (MDPs) and the Bellman operators, emphasizing contraction mappings, monotonicity, and fixed-point theory that yield convergence guarantees and rates ...

This paper addresses the challenge of merging hierarchical navigable small world (HNSW) graphs, a critical operation for distributed systems, incremental indexing, and database compaction. We propose three algorithms for this task: Naive Graph Merge (NGM), Intra Graph Traversal Merge (IGTM), and Cross Graph Traversal Merge (CGTM). These algorithms differ in their approach to vertex selection ...
