The main aim of this study is to determine the relations between the readiness for training and the performance of the military training ground of kinesiology students. Readiness of students for military training was measured by a questionnaire with several items on which students assessed various forms of readiness (fitness, psychological readiness and overall readiness) and various forms of personal competencies (motor skills, technical knowledge and military knowledge) to attend military training. The performance of the army polygon was measured on a standardized NATO infantry (army) obstacle course. Military training of students was conducted as a field education of the elective course kinesiology in armed forces in a military facility of the armed forces for 4 days. A statistically significant difference was found between respondents of different genders in the performance of the army obstacle course. The influence of predictors of readiness/knowledge proved to be statistically significant on the assessment of overall readiness for military training in both genders of examinees. Grouping subsamples of both genders of examinees according to the expression of their readiness/knowledge in two different clusters, a cluster of subjects with higher readiness and a cluster of subjects with lower readiness for military training. In both subsamples of subjects, it was found that their readiness for military training is not related to the performance of the army obstacle course. It is likely that the performance of the army obstacle course is significantly determined by some other functional-motor factors that were not included in this study.
