The aim of this study was to determine the differences in spending free time in kinesiology and non-kinesiology related activities between subsamples defined according to gender and age on the sample of students completing primary and attending lower secondary education. Daily physical exercise is very important for the health of children and youth. Failing to be involved in daily physical exercise and to participate in kinesiology related free time activities has become an important public health problem. This study was conducted on a convenience sample of boys and girls attending fifth to eighth grades. The total number of students who participated in the study was 847, of which 413 girls and 434 boys. A questionnaire, designed for the purpose of this research, was used to assess the level of students' activities in their free time. The significance of differences between subsamples defined according to gender was determined by Mann-Whitney U test, while the significance of age differences was determined by Kruskal Wallis test. The results of the Mann-Whitney U test confirmed the existence of statistically significant gender differences among fifth to eighth graders in the implementation of kinesiology and non-kinesiology related activities during free time. The analysis of kinesiology related activities shows that girls spend more time in the activities of walking, roller skating, playing badmiton, volleyball and dancing, while boys spend more free time cycling, playing football, basketball and handball. After analysing nonkinesiology related activities, it was established that boys are more interested in IT related activities (computer, playstation...) whose sole purpose is playing games and entertainment, while girls are more involved in activities that are fun, relaxing and educational. Significant age differences in the implementation of non-kinesiology related activities were also found among the students. The established difference is the most significant among age groups (younger and older students), but age differences are certainly also determined by natural laws of growth and development

The aim of this study was to determine the relation between physical activity and functional capacity at the primary school pupils. Many people are not aware that the health of the most important in human life and associated with the movement. In recent decades, the number of obese people, children and adolescents is is significantly increasing. The modern life style of children and young people are increasingly missing movement and outdoor games, is prevalent sedentary lifestyle (TV, Internet, Play Station ..) adverse effects the development of abilities and skills of children and their health status. The study included 80 students of the third grade of primary school, of which 43 boys (mean age 9.30 ± 0.46 years) and 37 girls (mean age 9.29 ± 0.47 years). The students attended two elementary schools in the city of Petrinja., First Primary School and Elementary School Dragutin Tadijanović. The survey was conducted in the school year 2014/2015. The sample of variables consisted of anthropometric measures of body height, weight, skin fold of the upper arm, back skinfold, abdominal skinfold. The functional abilities were measured test run for 3 minutes - F3, which is used to assess the level of functional ability in primary education in the Republic of Croatia. The level of physical activity was estimated PAQ-C questionnaire.   From the results it is evident that of the total sample 60% of them have a normal percentage of body fat, while almost 40% of students with excessive fat in the body. The conclusion of this study indicates a high percentage of students who are overweight. Functional capacity was inversely associated with indicators of obesity, which means that students with high levels of functional capacity have a lower percentage of body fat. School age is the best time to stimulate and positive impact on the growth and development of children and the missed possibilities to that age cannot be recovered in later stages of life.  Keywords: aerobic capacity, functional ability, obesity, students, school

School sports societies are organised with the goal to enable pupils to engage in their preferred sports. Also, this system is implemented in certain sports within school sports societies with the aim to facilitate better development of motor and functional abilities, and anthropometric characteristics. During training sessions of school sports societies, pupils should not be exposed to excessive training intensity. The training process should be in compliance with the principles of sports development, but also with the principles of growth and development of children and youth. The aim of this research was to determine the effects of a two-month training on the changes in motor skills in young female basketball players, members of the school sports society. The sample consisted of 10 schoolgirls, members of the school sports society at the Primary School Jabukovac. In the assessment of the effects of a two-month training, a battery of 12 tests was used to measure motor skills. Based on the obtained results it can be concluded that the two-month systematic training process in the school sports society consisting of three 45-minute sessions per week, along with regular PE lessons consisting of 2 lessons per week contributed to the transformational effects of motor skills in young female basketball players. The most significant transformations were observed in explosive strength, coordination and flexibility.

On the basis of a series of definitions (Findak, 1995; Klavora, 2008; Momirović, 1969; Mraković, 1971, 1992, 1997), Kinesiology as a science "studies the effectiveness of human movements, the controlled process of exercise, its principles and its consequences on human body in the broadest sense" (Prskalo Spori, 2016, p. 12), and strives to realize its futuristic role in securing the future of humankind, especially with reference to its most sensitive and vulnerable members. This role is realized through all its applied areas and branches, and especially through kinesiology education, which is the only one that, in the course of every individuals compulsory education, includes the entire population within the compulsory school subject Physical and Health Education. Apart from the already consensually accepted values ​of physical and health education: biological, economic, health, cultural and pedagogical (Findak, 1999), the same author (2014) highlighted the importance of changing the name Physical and Health Education to Kinesiology Education, which would reflect the attitudes of the fundamental science and profession; however, this change has not happened yet. In addition to the values realized through the school subject, whose name should be Kinesiology Education because of its scientific foundations, the value of kinesiology education has been confirmed in accomplishing a series of anthropological and educational tasks, and has even become the basis of different virtues including religion (Prskalo, 2017), which may be defined as a subjective mental state, a certain lifestyle and consistency in faith (Enciklopedijski teoloki rječnik, 2009). Prskalo (2018) points out that the issues of sustainable development contained in the Millennium Declaration of the United Nations with goals attainable by 2015 and the ones applicable today (Državni zavod za statistiku et al., 2006; Pavić-Rogoić, 2016), such as world without poverty and hunger, health and wellbeing, quality education, gender equality, clean water and sanitation, affordable energy from clean sources, dignified work and economic growth, industry, innovation and infrastructure, reducing inequality, sustainable cities and communities, responsible spending and production, climate protection, preservation of life on Earth, peace, justice and strong institutions, and consolidation of global partnership for sustainable development, are not exclusively related to one ​​scientific area or discipline. On the contrary, these issues belong to the field of kinesiology and all its applied fields. Key words: kinesiology, Kinesiology Education, sustainable development, students.

The objective of the research was to investigate to what extent students of fi rst and second grades of primary school participate in physical activities in their free time. We are living in the age of sedentary lifestyle, which is becoming a problem of public health. 189 respondents took part in this research of which 93 girls and 96 boys aged 7 to 9. To assess the level of students' activity in their free time, a poll was used consisting of eight questions from the questionnaire "Fels physical activity questionnaire for children" (FPAQ). Based on queries from the questionnaire, indices were calculated from the area of sports (IS), free time (ISV; household chores (IKP) and total physical activity result (UTA). To assess body composition, anthropometric measures of height, mass, BMI and percentage of fat in the body were used. To assess those, we used the device for measuring physical composition-Omron BF500 Body Composition Monitor. Results indicate that 59.26% do not meet daily recommendations for participating in physical activities. As regards the difference in students' age, it is notable that second grade students are somewhat more physically active. Observing average results, it is clear that students were most physically active in their free time. The lowest values were recorded in the area of sports at school, (1.15), yet lower values were also obtained from sports club activities (2.06). It is evident that students of that age are minimally active during their PE classes and this is a segment where the number of physically active students can be increased. Increasing physical activity at school shall encourage students to participate in physical activity outside educational institutions.
