The fundamental goal of PE classes is the acquisition and improvement of children's motor skills, habits and knowledge, as well as encouraging proper growth and development as the basis of their health. With the help of physical activity, the student develops his morphological characteristics, motor and functional abilities. In order to get the most accurate assessment of the student's work effect, it is extremely important to monitor and check the kinanthropological characteristics of the student throughout the year using initial, ongoing, periodic and final checking. The aim of this paper was to assess the progress in the kinanthropological characteristics of students during one school year by comparing them with normative values with regard to the age of the students, to determine the significance of the differences between the initial and final measurement of the kinanthropological characteristics of students, and to assess the significance of the differences in the kinanthropological characteristics of students with regard to gender, nutritional status and involvement in extracurricular sports. The research was conducted on a sample of 39 students (16 male and 23 female students) from two elementary schools in Zadar. Nine variables were used to assess the kinanthropological characteristics of students in this research. In order to assess their specific morphological characteristics, the students' height and body mass were measured, based on which the body mass index (BMI) was calculated as an indicator of the student's level of nutrition. Furthermore, a standardized battery of test was used to assess the students' motor skills, which examined the students' speed, explosive reflex power, coordination, repetitive strength, and flexibility. Also, the F'3 test was measured, which assessed the students' functional ability. The results of the research showed that the students improved in kinanthropological characteristics during one school year. It was also determined by the t-test that there are no statistically significant differences in the kinanthropological characteristics of students with regard to gender, except in the variable standing forward bend, in which female students achieved better results. However, there are statistically significant differences between students who are physically active outside of school and those students who do not participate in extracurricular physical activities, showing that students who play sports outside of school achieve better results. Furthermore, the results of the research showed that there is a statistically significant difference between students who belong to normal range BMI and those who are overweight. Those students who belong to the group of normal range BMI achieve better results in most variables during measurement. The conducted research proved that there is significant progress in certain kinanthropological characteristics during one school year, especially among those students who additionally engage in a certain kinesiology activity in their free time.
