The aim of the research is to determine the difference between hydration of the body before and after the judo training. The sample of respondents was boys (N = 30) aged 11-12 years. Body mass (MASS), body mass index (BMI), body fat (FET) and body water (BTW) were measured. The mean values in the second measurement were lower: body weight by 0.6 kg, body mass index by 0.5, body weight for 0.2 kg and body water by 0.8 kg. The trend of decreasing the minimum and maximum values is also noticeable in all treated variables except in the case of maximum values of body fat variables. Statistical significance was confirmed by t-test at p<0.05 in case of body mass index and body weight index, and p<0.01 in case of body water variable. The body fat change was not statistically significant. After the conducted study, it can be concluded that there is a justified need for rehydration during training. In order to maintain the appropriate training intensity, judo coaches should plan organized breaks. Coaches or other trainers of physical activities with the contents of the judo sport are recommended to provide organized breaks during which the course will be rejuvenated.

The aim of the study is to evaluate and determine the differences in the status of lower limbs of primary school pupils in primary school. On the sample of 68 respondents, 34 boys and 34 girls, who attended the first grade of the primary school “Ivo Lola Ribar” from Novi Sad, an assessment of the postural status by the method of “Napoleon Wolansky” was carried out with an accent on “X” and “O” the shape of the leg and the holding of the vault of the soles. For the statistical data processing, the non - parametric Hi - square test method was used. The results showed that statistically significant differences were not found, indicating a similar state of the observed segments of the postural status of this sample (p> 0.05). In the leg estimation variables, it can be concluded that there are no statistically significant differences between boys and girls in the segments of the “X” leg (p=0.323), as well as the “O” leg (p=0.555). No statistically significant differences were observed between the subjects of the different sex (p=0.614) nor at the foot of the foot. A slightly higher representation of the good holding of this segment was observed in the sub-girlfriends. The results show that flat feet were represented with 7.48% of the total sample. Based on the results it can be concluded that it is generally necessary to apply preventive exercises and activities in the teaching of physical education, but also to work towards the early diagnosis of these deformities.

The main aim of this research was to determine the differences in attitudes between boys and girls of the fourth grade towards the continuation of physical education. The sample of respondents was 121 pupil of the elementary school “Vuk Karadžić“ from Podgorica. Students are divided into 2 sub-samples according to the gender criterium (74 boys, 47 girls). We used an anonymous standardized questionnaire adapted to this research. The results were processed descriptively and tabulated. A H2 test was used to determine statistically significant differences. The results showed that differences between boys and girls appear only in favorite sports, while in other issues there are no statistically significant differences.

The main goal of this research is to determine whether there are statistically significant differences in the level of anthropometric indicators among athletes of different sports directions (basketball and volleyball players), that is, to determine the differences in the changes in the anthropometric indicators of athletes. In accordance with the goal, a transversal study was conducted in which the empirical and statistical methods were applied, and the research technique was testing. The study was conducted on a sample of 50 subjects, a male sex divided into two subunits, an age range of 13 to 15 years. In this study, 12 anthropometric variables were tested: body height, arm length, leg length, knee diameter, bicrystalline range, bichromium range, body mass, median volume of the thorax, circumference, upper abdomen, skin abdomen and skin set of lower legs. For all applied variables, the central and dispersion parameters as well as measures of asymmetry and flattening were calculated, and the distribution normality was verified by Kolmogorov-Smirnov test. T-test was applied to verify that the system of applied variables has statistically quantitative differences between groups. For the determination of the differences between the group of variables and the group of subjects, discriminatory. On the basis of the obtained results, it can be concluded that there are statistically significant differences in anthropometric indicators in athletes of different sports orientations. This research can be used by trainers who realize training programs with these and other athletes in order to achieve better results.

The main goal of the research was to make one Meta-analyze of original scientific papers, who dealt with the identification on the sport balls repulsion depending on the pressure within. Sport balls of standard dimensions was released on the flat solid surface from the height of nine meters for four times. At the first release the air in the sport balls was under prescribed pressure. At the second release the pressure in the pumped sport balls is reduced by 5%, at the third reduced by an additional 5%, at the fourth reduced by another 5%. The setting of the experiment was carried by cinema shooting of free fall of the prescribed sport balls and a series of rebounds after the rejection of solid surfaces. One can conclude that the distance crossed and the total duration of four successive bouncing mostly dependent on inner pressure. In this study, the initial speed of a sport ball were unchanged and only inner pressures were changed. It was determined how much the height of the rebound is reduced and the duration of the rebound, respectively, depending on the reduction of inner pressure. This Meta-analyze shows that the initial speed of the ball can be increased by increasing the inner pressure in the balls.
