Title: Analysis of Heart Rate Variability (HRV) during the Selection Process for the COMMANDOS Group. Objectives: The aim of this study was to analyze changes in heart rate variability among individual participants during the selection process for the COMMANDOS group and to compare them with each other. Methods: This theoretical-empirical study focused on monitoring changes in heart rate variability (HRV) during the selection process for the COMMANDOS group, which lasted from Friday 2 PM until Sunday noon. The research sample consisted of 15 students physically and mentally demanding selection process led to the gradual dropout of participants, with only two completing the entire measurement. The initial measurement was taken on Friday at 14:00, and further measurements were taken at least twice a day, with intervals not exceeding 10 hours between measurements, totaling 7 measurements. Flexi Guard measuring systems, which allow long-term telemetric monitoring of health- physiological parameters in real time, were used for the measurement. Before the start of the selection process, participants completed a resilience questionnaire to assess their mental resilience. During the measurements, responses to the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Perceived...

Exercises and motor tests used for military personnel training and testing: a systematic review
Mašek, David ; Vágner, Michal (advisor) ; Maleček, Jan (referee)
Title: Exercises and motor tests used for military personnel training and testing: a systematic review. Objective: The aim of this bachelor thesis was to determine what exercises and motor tests are most commonly used to develop and test strength abilities in military personnel and then compare their frequency and purpose of use in military training. Methods: This bachelor thesis was conducted in the form of a systematic review dealing with exercises and motor tests designed for training and testing the strength abilities of military personnel. The methodological procedure of the study was conducted based on the recommendation of PRISMA. To initially select potentially suitable studies, a script was constructed and used to search the Web of Science, Scopus, and PubMed databases. A non- systematic search of the Google Scholar database was conducted for added other studies. The selected studies had to meet predefined inclusion criteria, and all studies were checked for risk of bias before inclusion in the systematic review. Results: When testing the strength of military personnel, the highest frequency was recorded in motor tests, where the resistance was formed by the weight of one's own body (cranks, seats, and push-ups). Furthermore, strength endurance testing prevailed over other types of...
