The primary goal of this research was to determine the differences in kinematic parameters between the first and second serves in tennis among the elite players of the German league. The sample of respondents in this research consisted of 30 elite male senior players of the German League who have "Leistungklasse" from 1 to 7. The kinematic parameters that were analyzed are: Height of ball impact (KPVUL), Racket speed (KPBRE), Ball speed (KPBLO), The angle at the elbow joint of the arm that hits the ball (KPULZ), Oscillation of the vertical projection of the center of gravity of the body (KPOVP), Jump height (KPVSK), Ball launch height (KPVIL), The point of contact between the ball and the racket "sweetspot" (KPMLR), Ball rotation "Top spin" (KPRLO). The video recording required for kinematic analysis was acquired with two Casio EX-F1 digital cameras at a frequency of 200 images per second. The camera was placed at an angle of 900 in relation to the recording plane, and they were at a distance of 10 m. Space calibration was performed with the help of a calibration frame (200 x 200 cm). We have installed Zepp Tennis Smart Sensor 2.0 in the handle of the Wilson Pro Staff RF97 Autograph racket, using the Zepp Tennis application software. "Kinovea" software was used for service analysis and obtaining kinematic parameters from video recordings. By analyzing the results of the T-test for independent samples, it can be seen that there are statistically significant differences in five of the nine analyzed kinematic parameters : KPBRE – kinematic parameter of racket speed (Sig.=.000), KPBLO – kinematic parameter of ball speed (Sig.=.000), KPULZ – kinematic parameter angle in the elbow joint (Sig.=.000), KPMLR – kinematic parameter point of contact between the ball and the racket (Sig.=.000), as well as a variable KPRLO – kinematic parameter of ball rotation (Sig.=.000). Larger numeric values in variables: KPVUL – kinematic parameter ball impact height, KPOVP – kinematic parameter of oscillation of the vertical projection of the center of gravity of the body, KPVSK – kinematic parameter jump height and KPVIL – kinematic parameter ball impact height, show a difference but it is not enough to be statistically different.

The World Health Organization (WHO) released guidelines for physical activity, sedentary behav-iour, and sleep for children under 5 years of age in 2019. In response to these guidelines, this study aimed to determine the proportion of preschool children (ages 3-5 years) who met the WHO guidelines. The time spent in physical activity, sedentary behaviour and sleep were objectively measured using accelerometer (ActiGraph wGT3x-BT). Screen time and sleep quality were assessed via parent questionnaire. Focus groups were con-1 ducted with parents and childcare staff to determine the feasibility of the protocol. The results showed that only 23% of the children met all three guidelines, and compliance rates varied for each guideline. The physical activity time guideline was met by 64% of children, the sleep duration guideline was met by 74% of children, and the screen time guideline was met by 53% of children. Only a low proportion of children met the WHO guidelines. The methods and devices used in this pilot study proved to be feasible and this has paved the way to conduct the main SUNRISE study in Bosnia and Herzegovina.

A system of fifteen variables (7 morphological and 8 variables for assessing postural status) was applied to a sample of 284 male and female students from the first to the third grade of primary school, with the aim of determining the differences between boys and girls. The results showed that there were statistically significant differences between the examined samples in the following morphological variables: in the first class (body weight and skin fold of the triceps), in the second class (body height, body weight, skin fold of the triceps and skin fold of the biceps) and in third grade (body height, skin fold of triceps, skin fold of back, skin fold of biceps, and skin fold of lower leg). Statistically significant differences in the variables for assessing postural status exist in the following variables: in the first grade (head posture, shoulder posture, shoulder posture, chest shape and leg shape), in the second grade (shoulder posture, chest shape, and spinal deviation in frontal plane) and in the third grade (deviation of the spinal column in the frontal plane, holding the anterior abdominal wall and the shape of the legs). Based on the obtained results, it can be concluded that in the younger school-age in morphology there is a significant sexual dimorphism and with it in connection with the change of postural status.

Growth and development are indicators of good health, as well as a mirror of quality nutrition and quality of life. By monitoring growth and development, the relationship between motor abilities and morphological characteristics is recognized. The period of younger school age is characterized by strong growth and development of all anthropological dimensions, especially morphological and motor ones, which differ significantly in children, concerning adults. This transversal research aimed to determine the differences in morphological characteristics and motor abilities between lower primary school students. The research was conducted on a sample of 1233 girls, I - IV grades of primary schools from the area of the City of Tuzla. The sample of variables consisted of a set of 10 tests to assess certain anthropological dimensions (5 morphological and 5 motors), appropriate to the age of the study population. Univariate analysis of variance with multiple comparisons was used to determine the differences in the studied spaces between students of different grades, with the applied post hock Bonferroni test. The obtained results showed that there are statistically significant differences in all applied variables (morphological and motor). between treated groups at the level of significance (p≤0.05). The results of the research draw attention to the importance of early stimulation of morphological-motor development and a healthy lifestyle in female students, which are characterized by regular physical activity and a healthy diet. Optimal levels of motor skills, well-developed fundamental motor skills and a healthy body structure are of great importance for health, quality of life-related to health and overall well-being of younger school-age students.

One of the main accompanying parts of the growth and development of students is their systematic monitoring of certain anthropological dimensions. This research, which is of a transversal character, had a goal to determine differences in morphological characteristics, basic-motor and functional abilities between students from different grades of high school. The population from which the sample of 349 respondents was taken is defined as the population of the first, second, third and fourth grades students from Zavidovići high schools, male, 15 to 18 years old ± 6 months. The sample of variables consisted of a set of 20 (twenty) tests for the assessment of anthropological dimensions, as follows: morphological characteristics (4 variables), basic-motor abilities (15 variables) and functional abilities (1 variable). A univariate analysis of variance with multiple comparisons was used to determine the differences in the study spaces between students of different grades of high school, with the applied Bonferroni post-hoc test. The obtained results showed that there are statistically significant differences in three of the four morphological variables (body height, body weight and body mass index), in eight of fifteen motor abilities (ball rolling with nondominant hand, direction switch on training ground, side stepping, figure eight with crouching, running transmission, forward bend on the bench, standing long jump and sit-ups) and one functional variable (1000 m run) between the treated groups at the significance level (p≤0.05). The obtained results can be subject to a critical analysis of the physical and health education teaching process in order to more efficiently organize and rationalize the teaching of physical and health education. This data may show certain shortcomings of year-round application of funds as part of the realization of the high school plan and program.

In order to monitor the intensity of work during one hour of physical and medical education in 37students of the Faculty of Philosophy Department of Classroom Teaching in Tuzla, the measurement of the effects of work through the application of polygon barriers was performed as the most complex methodological-organizational form of work. The effects of working and mastering the polygon through the particular phase of the clock (introductory, main A and B) are expressed by the number of heart beats. The heart rate measurement was performed by palpation of the artery radial at the beginning and end of each phase of the clock. During the measurement period, rest was also involved that had the role of a transitional factor from the submaximal / maximal values of the heart rate to the values that would bring near the possibilities and state of the organism to the completion of the final phase of the clock. The results obtained by this research show that the heart rate values in all phases of the clock differ significantly between each other and that the highest intensity of work is achieved in the main B-hour phase, indicating the appreciation of the physiological and emotional load curves that prevail over the course of physical and health education . This suggests that the polygon barrier as the most complex method-organizational form of work contributes to the intensification of work during the class of physical and medical education.

Based on a sample of 112 boys seventh and eight grade of Elementary school, age 13 to 15, we applied system of 21 variables, among them 18 variables were to estimate motor abilities and 3 were to estimate situational-motor abilities in volleyball and all is to determine mutual relations. According to results gained with appliance of canonical correlation analysis we can conclude that relations between observed group of variables – motor ability (as predict group of variables) with criteria group of variables (situational-motor abilities) will result with statistically significant coefficient of canonical correlation.
