Analysis of the warm-up part of the physical education lesson taught by primary teachers and physical educators

In the master's thesis, we focused on the introductory part of the Physical education lesson that is taught by either primary teachers or PE teachers. This part of the lesson was chosen as some deviation was observed between the theoretical bases presented in literature and its practical implementation during our studies. At the beginning of the theoretical part is a short summary explaining the importance of the introductory part of the Physical education lesson and who (primary teachers or PE teachers) is supposed to teach Physical education. We presented the motor development of children, all consisting elements of the introductory part of the lesson, the problem of incorrect posture and the previous research carried out on the topic. 30 teachers participated in the empirical part of this dissertation. 15 of those were primary teachers and 15 PE teachers. Using an observation form which was prepared in advance we observed: elements of the introductory part of the lesson; duration; the number of stretching, strengthening and relaxing exercises, their number of series and repetition; the presence of counting, individualization and correction of students' mistakes; the layout of students and the type of demonstration used; used terminology; the connection between the introductory part and the main part of the lesson; choice and implementation of elementary games and exercises which counteract the negative effects of sitting on our posture and bodies. The results of this study show that there were some discrepancies between the theoretical bases and practical implementation. There were, however, no differences between theoretical bases and practical implementation concerning the elements of the introductory part of the lesson, specific warm-up, the number of stretching exercises, duration of general warm-up, correction of students' mistakes, terminology, implementation of elementary games and protection from dangerous situations. Additionally, there were differences between the theoretical bases and practical implementation of primary teachers and PE teachers concerning the number of repetitions within strengthening exercises, duration of specific and total warm-up, the layout of students and the connection between the introductory and the main part of the lesson
