Reliability of a load-carrying test by military personnel

Title: Reliability of a load-carrying test by military personnel. Objectives: This study aims to determine the reliability of carrying a load of 15kg test designed for occupational testing of military personnel of the Czech Army. Methods: This theoretical-empirical work tested a deliberate set of students from the Military Branch at the Faculty of Physical Education and Sport of Charles University. The research population consisted of 17 probands with an average age of 22.1 years, an average height of 179.4 cm and an average weight of 78.9 kg. It uses the reliability test-retest method. The probands underwent 8 timed trials, then recorded in Microsoft Excel. The recorded results in Microsoft Excel were converted to txt format and then descriptively and statistically analyzed in Jasp (0.17.1.0). An intraclass correlation coefficient of the ICC type of 3.1 was used to statistically assess the consistency of performance, accompanied by 95% confidence intervals [LL, UL]. Results: Performance across test trials showed a moderate level of consistency with ICC (3,1) = 0,725, [0,567, 0,866]. ICC values ≥ 0.5 were considered sufficiently consistent.
