© 2020, Pan - European University Apeiron. All rights reserved. The purpose of this study is to establish the existence of gender differences in motor skills in the preschool period as well as to check their nutritional status. The classification of their nutritional status has been per-formed based on their body mass index (BMI), based on the percentile values according to Centers for Disease Control and Prevention, (2000). Total sample consisted of 188 examinees with average values of body height (BH=124.59 cm±5.76) and body weight (BW=24.32 kg±3.11) with average age of 6.39±0.44 years, out which boys (N=107) and girls (N=81). Non-experimental research design, ex post facto correlation research plan, has been used. The battery with seven motor tests according to Bala and Popović (2007), has been used in this research. The study results show that the prevalence of malnour-ished children is 10.64%, well nourished 72.34%, tending to become obese 9.57% and obese children 7.44%, also with the existing gender difference in motor abilities in fa-vour of better average values of boys in coordination, explosive and repetitive strength. The research results show that there is the satisfying percentage of normally nourished children and that the linearity of their nutritional status is in accordance with their motor status, growth and development. On the other hand, the perceived gender difference are present due to differentiation of motor abilities that occurs at this age. The authors point out that greater differences and variability regarding the level of nourish-ment and motor abilities of children can be expected only in prepuberty period, which will happen in the next phase.

The research presented in this paper aimed to determine the effects of using circuit training as a teaching method in physical education. The sample consisted of 95 students (age 7.7±0.7 years), divided into two groups. Circuit training was used in physical education classes with the experimental group (N=49) over the course of eight weeks, while the control group (N=46) had physical education classes according to the regular P.E. program. All the subjects in the study were given four motor skills tests to assess their speed, coordination, explosive strength and repetitive strength. Multivariate analysis of covariance showed that at the end of the study, subjects in the experimental group performed significantly better than subjects in the control group, while the paired sample T-test found the effects of the procedure to be statistically significant (p=0,00). The study highlights the importance of using circuit training as an organizational form of instruction in physical education to improve the motor skills of school children.
Ekspertni sistemi u sprintu
(Faculty of Education in Užice, 2019) Pelemis, Vladan; Pavlovic, Slobodan; Solaja, Anita
Cilj rada je da se prikažu i jasnije definišu ekspertni sistemi u sprintu, tj. načini kontrole i ocenjivanje sprinta kao i evaluacija postignutih rezultata, kod dece selektovane za atletiku školskog uzrasta. U atletici još nije modelovan ni jedan ekspertni sistem koji bi omogućio trenerima sistematsko praćenje rezultata sportista različitog uzrasta, kao i predikciju njihovih rezultata u budućnosti. Brz razvoj tehnologije omogućava nam dobijanje sve većeg broja objektivnih podataka na osnovu kojih možemo da dobijemo vernu sliku tehnike kretanja. Moramo ipak, naglasiti, da je većina metoda za ocenu tehnike atletskih disciplina dosta komplikovana, zahteva posebne aparature i posebno obučen kadar. Predloženi kriterijumi za kontrolu i ocenu sprinta predstavljaju sponu između naučnih istraživanja i prakse. Implementacija izloženih kriterijuma je primenjiva kako u školsko obrazovnom sistemu, kao kolevci mladih talenata, tako i u sportskim klubovima, kao kolevci svetskih rekordera.
Indeks telesne mase (ITM) kao značajan faktor u ispoljavanju motoričkih sposobnosti dece mlađeg školskog uzrasta
(University of Belgrade, Teacher Education Faculty, 2018) Pavlović, Slobodan
The aim of this study was to determine the differences in motor skills in the lower primary school children depending on the value of the body mass index (BMI). The sample consisted of 174 students of the lower primary school grades in the city of Uzice, aged 10 ± 0.65 years. Seven motor variables were analysed to determine the quantitative differences in the areas of the motor functioning of children. The children were categorised in three groups based on the body mass index (underweight, normal weight and overweight). The results obtained in this study indicate that there are differences in the motor space among the groups of respondents. The biggest difference was identified in the speed of movement, coordination of the whole body, static strength of arms and shoulders and flexibility. A statistically less significant difference was also identified in the repetitive strength. The results suggest that children with normal nutritional status have the best motor skills, compared to the underweight and overweight children. The findings are indirectly related to the quality of physical education teaching, because students with better motor skills are more active in class in terms of movement
Motor skills of primary school children: The differences compared to age
(Faculty of Education in Užice, 2020) Pavlović, Slobodan; Marinković, Dragan; Mitrović, Nebojša
Physical education, from the earliest age in preschool institutions, and then through primary and secondary schools, is the only place where children can, in the right way, acquire the knowledge on sports, skills, behaviour, necessary in order to get the continuity of physical activities in the adulthood. Primary school is a period when the students experience great changes in the overall developing status. Therefore, Physical Education has a fundamental role in the development of psychosomatic characteristics of children. While planning lessons of Physical Education, there is a special emphasis on the development of motor skills. The goal of this research refers to the establishing of the existing differences in the motor space of primary school children in relation to age. The sample consisted of 231 examinees who attended 3rd, 4th, 5th and 6th grade (age 11 ± 1.6 years), out of which there were (N = 109; TV = 147.6 ± 7; TM = 39.6 ± 7.1) boys, and (N = 122; TV = 148.3 ± 5.9; TM = 40 ± 5.3) girls. All examinees were the students from the territory of Zlatibor region and with the signed permission for performing testing by both parents. Motor skills have been estimated within school Physical Education, all with the purpose of getting more realistic picture on the motor skills of children. The presented results point to the existing differences between the groups of examinees of both genders on a general level, as well as the individual differences within the motor space. These differences are more noticeable with boys (F = 5.92; P = .00) than with girls (F = 4.79; P = .00). Statistically greater differences with boys have been noted in the following variables: "Hand tapping", "Hand clapping", "Throwing basketball ball", "the 30 m running flying start", "Pull-ups", and "Torso lift-ups". With girls, statistically significant difference have been notes in the following variables: "Throwing basketball ball", "the 30 m running flying start" and "Torso lift-ups". The value of this work is reflected in the fact that, during testing, a great number of tests were used for estimation of the examinees' motor space, all with the purpose of getting more complete picture on the existence of differences among the groups, categorised by gender and age. The importance of testing and perception of differences in motor skills and their monitoring presents one of the important activities during PE classes, all with the purpose of the adequate lesson programming, but also monitoring the motor development.

(2021) Marinković D.; Pavlović, Slobodan; Madić, Dejan; Obradovic B.; Németh Z.; Belic A.
Postural stability (PS) is an important function for maintaining equilibrium during periods of standing still, locomotion, and any motor activities that require high degree of balance. High PS is essential in different sports for the regulation of voluntary movement and for improving athletic physical condition and performance. Purpose: The purpose of this study was to compare the static PS of elite rowing athletes and field sport athletes. Methods: A total of 90 elite athletes (age: 23.9 ± 1.97 years; body height: 174.9 ± 8.9 cm; body weight: 67.7 ± 12.03 kg) were divided into Rowing (N = 47) and Field sport (N = 43) athlete groups. Static PS parameters were assessed with a static double-leg and single-leg standing stability test on a force plate platform. Results: The multivariate analysis of variance showed a general stability difference between the groups (F = 13.255; P ≤ 0.0001), in double leg stability (F = 16.735; P ≤ 0.0001), and left leg (F = 15.097; P ≤ 0.0001) stability parameters. When analyzing variables separately, significant statistical differences were observed in favor of the Rowing group in double leg sway area (p = 0.017; ES = −0.07), double leg center of force (COF) traveled way (p ≤ 0.0001; ES = −27.42), length function of surface (p ≤ 0.0001; ES = −26.86), right leg ML displacement (p = 0.030; ES = −0.46), left leg sway area (p = 0.030; ES = −0.44), left leg COF traveled way (p ≤ 0.0001; ES = −60.63), left leg AP displacement (p = 0.043; ES = −0.44). Conclusion: These results underline the differences in rowing and field sport athletes in terms of static PS. The characteristics of sport and competition may affect PS, and it is important to adjust training modalities for the required level of PS in every sport, especially in rowing.
Predikcija indeksa telesne mase (ITM) i fizičke aktivnosti roditelja na fizičku aktivnost učenika na času fizičkog vaspitanja
(2018) Pavlović, Slobodan
Imajući u vidu da je fizička aktivnost učenika na časovima fizičkog vaspitanja značajan pokazatelj kvaliteta nastave, sprovedeno je istraživanje sa ciljem da se utvrdi u kojoj meri indeks telesne mase (ITM) i fizička aktivnost roditelja doprinose predikciji obima i inteziteta fizičke aktivnosti učenika na času fizičkog vaspitanja. Istraživanjem je bilo obuhvaćeno ukupno 259 učenika trećeg i četvrtog razreda (uzrasta 10 ± 1,1 godina) osnovne škole (137 dečaka i 122 devojčica). Fizička aktivnost je merena po obimu pedometrom Coach Gear i po intezitetu pulsmetrom Suunto Memory Belt. Za procenu fizičke aktivnosti roditelja primenjen je Međunarodni upitnik o fizičkoj aktivnosti (IPAQ-International Physical Activity Questionnaires), dok su podaci o indeksu telesne mase (ITM) dobijeni standardnom procedurom, a na osnovi podataka o telesnoj masi i telesnoj visini roditelja. Dobijeni rezultati ukazuju da je predikcija fizičke aktivnosti roditelja statistički značajna (p < 0.01), kod dečaka i devojčica na obe kriterijske varijable (obim i intezitet fizičke aktivnosti), dok je predikcija indeksa telesna mase (ITM) izostala kod oba pola. Na nivou pojedinačnih varijabli fizička aktivnost oca ima najveću prediktivnu moć. Važno je da roditelji podrže fizičku aktivnost svoje dece, da budu rol-modeli, da učestvuju zajedno sa decom u fizičkoj aktivnosti, da podstiču aktivnu igru i bavljenje sportom. Sve aktivnosti koje škola i/ili nastavnici preduzimaju radi poboljšanja fizičke aktivnosti učenika u školi, treba planirati tako da intervencija uključuje i roditelje.

Maintaining quality physical education classes, as provided for in the curriculum, encounters numerous problems and difficulties in implementation on a daily basis. Pupils' full engagement and activity in the physical education class is an important precondition for physical education to really be in the function of healthy growing up and preparation of pupils for an active lifestyle. The aim of this research was to determine the differences in the motivation and physical self-concept of pupils relative to the level of their physical activity in the physical education class. The research included 423 students from the territory of the city of Užice (aged 10 ± 1.3 years), 227 boys and 196 girls, organized in three groups according to the level of physical activity in physical education class (A-low; B-medium; Chigh). A modified Self-Regulation Questionnaire (Ryan & Connell, 1989) was used to assess pupils' motivation orientations, and appropriate subscales of the Self-Perception Profile for Children measuring instrument (SPPC, Harter, 1985; rev. 2012) were used to assess physical self-concept. Physical activity (scope (number of steps) and intensity) of pupils in physical education class was measured using the CoachGear pedometer and the Suunto Memory Belt heart rate monitor. The presented results indicate the existence of significant differences among the groups of respondents of both sexes in relation to the level of physical activity of pupils of younger school age. Based on the obtained findings, it can be concluded that the expressed differences are greater in boys than in girls. The results published in this study support most of the findings indicating differences in motivation and physical self-concept. It was further determined that less active children generally show lower levels of motivation, as well as the values of the physical self-concept. The authors believe that in the planning and programming of physical education classes, emphasis must be placed on creating a favorable "climate" for teaching. Initial education of preschool and primary school teachers must be innovated in accordance with the new requirements and expectations that society puts before school physical education.

(2022) Ujsasi D.; Filipovic K.; Zvekic-Svorcan J.; Nemet M.; Đuričin A.; Jokšić-Mazinjanin R.; Pavlović, Slobodan; Jovanović, Danijela; Popović, Boris; Štajer, Valdemar; Radanovic, Danilo; Marinković D.; Cvetkovic M.
Rotator cuff disease, external and internal impingement syndromes, low shoulder stability, various types of trauma, and overuse injuries are all related to sports activities. In order to check symptoms in patients with disability and shoulder pain, clinicians use different methods and diagnostic imaging assessment. The research is aimed at evaluating whether there is a difference between provocation function tests (PFT) and ultrasonographic (US) testing of muscles within the rotator cuff in elite collegiate athletes. Patients (n=184) were recruited from university team sports selections and tested with a standardized US examination of the shoulder and five PFTs (Speed's test, Neer's test, Hawkins test, lift-off test, Yergason's test). Based on the VAS pain assessment scale, 60 subjects had some pain, which was taken for further processing in the work (124 subjects did not have the presence of pain and were excluded from further processing). The US examination was conducted using Voluson 730 apparatus, by a linear probe, with the frequency in the range of 6-12 MHz. The chi-square test showed significant differences between PFT and the occurrence of shoulder muscle tendinitis for the following variables: Speed's test and subscapularis tendinitis (p=0.02) and Speed's test and infraspinatus tendinitis (p=0.01); Neer test and biceps brachii caput longum tendinitis (p=0.01), Neer test and supraspinatus tendinitis (p=0.02) and Neer test and infraspinatus tendinitis (p=0.01); lift-off test and subscapularis tendinitis (p=0.05); and Yergason's test and biceps brachii caput longum tendinitis (p=0.03) and Yergason's test and subscapitis tendinitis (p=0.01). The greatest effect of differences was observed in Neer's test and biceps brachii caput longum tendinitis (ϕ=0.60), while the other effects can be described as medium and small in most cases. It can be concluded that functional tests are good predictors of soft tissue changes in the muscles of the rotator cuff of the shoulder. Further monitoring and analysis are needed on a larger number of athletes.
