The aim of the research is to determine whether there are gender differences between younger school-age children, and whether those differences within the sub-sample are influenced by the state of mass and motor skills. The whole sample included 285 respondents age 7.27±0.43, of which 144 boys (50.52%), and 141 girls (49.48%) who attended the first grade on the territory of the Province of Vojvodina (Republic of Serbia). The Eurofit battery of tests was used. The research results show that the prevalence of children with severe thinness in the whole sample is low 3.87%; children with normal mass 65.26%; pre-obese children only 18.59% and obese children only 12.28%, so that gender differences in motor skills considering the whole sample, apart from the mass, are between average values for boys considering explosive strength of the lower extremities, repetitive strength of the body and agility. Statistically significant differences within the sub-sample considering motor abilities were seen neither in boys nor in girls of different mass. The research findings show that there is significant percentage of children with normal mass and that the flow of their mass is within their growth and development. Their motor development within the sub-sample also flows equally, and gender differences are present because of differentiation of motor skills, which appears in this period. The authors think that greater differences and variables in respect to mass and motor activities are to be seen in the period of pre-puberty.

This detailed anatomical examination with measurements of the extracapsular part of a MGA could be of clinical importance and useful in knee surgery for the prevention of vascular injury of MGA and PA, as well as in radiological examination of the knee region.

The research was conducted with the aim of using experimental methods, scientifically determine whether an additional physical exercise program in regular working conditions of a preschool institution could result in significant changes in the motor skills of preschool children with an average age of 6.210.56 years. There were enrolled a total of 64 pre-school children, girls (n=28) and boys (n=36) of preparatory preschool groups in preschool "Čukarica" in Belgrade. A preexperimental research plan was used, specifically a single-group design, pretest-posttest. A sample of measuring instruments of motor skills was compiled according to a reduced theoretical model (Kurelić et al., 1975; Gredelj et al., 1975) taken from the research of Bala Popovic (2007). The experimental factor was realized with a total of 48 terms of 35 minutes and lasted for a 24-week time interval. The results of the study indicate that the quantitative changes in the final measurement are reflected in the repetitive force of the torso and coordination in favor of better average values of the boys. Two hypothetical motor factors were isolated on initial and final measurements, which can still be interpreted as one general Motor Factor. Qualitative changes in the structure of both extracted factors on the final measurement were not observed. The authors believe that a regular physical education program in pre-school institutions is not sufficient for a preparatory preschool group, and that additional kinesiological activities achieve better results in the mechanism for structuring the movement and regulating the duration of excitation, especially if it is directed towards the development of biotic motor knowledge. On the other hand, they believe that newer and more meaningful solutions must be found in terms of differentiated physical exercise programs for children, and that only such solutions could lead to qualitative changes in the structure of isolated factors.Key words: coincidence of factor saturation; differences; kinesiological activities; motor skills; pre-school children.Istraživanje je provedeno s ciljem znanstvenog utvrđivanja da li dodatan program tjelovježbe u redovitim uvjetima rada predkolske ustanove može rezultirati značajnim promjenama u motoričkim sposobnostima djece predkolske dobi s prosječnom dobi od 6,210,56 godina. Uključeno je ukupno 64 djece predkolske dobi, djevojčica (n=28) i dječaka (n=36) predkolskih skupina u predkolskoj ustanovi "Čukarica" u Beogradu. Upotrijebljen je pre-eksperimentalni plan istraživanja, konkretno dizajn jedne skupine, pretest-posttest. Uzorak motoričkih mjernih instrumenata sastavljen je prema reduciranom teorijskom modelu (Kurelića i sur., 1975; Gredelja i sur., 1975) uzeti iz istraživanja Bale i Popovića (2007). Eksperimentalni faktor bio je realiziran s ukupno 48 termina od po 35 minuta i trajao je u vremenskom intervalu od 24 tjedna. Rezultati istraživanja pokazuju da se kvantitativne promjene u finalnom mjerenju odražavaju u repetitivnoj snazi trupa i koordinaciji u korist boljih prosječnih vrijednosti dječaka. Izolirana su dva hipotetska motorička faktora na inicijalnom i finalnom mjerenju, koji se mogu interpretirati jo uvijek kao jedan i to Generalni motorički faktor. Nisu opažene kvalitativne promjene u strukturi oba ekstrahirana faktora na finalnom mjerenju. Autori smatraju da redoviti program tjelesnog odgoja u predkolskim ustanovama nije dovoljan za pripremnu predkolsku skupinu, te da dodatne kinezioloke aktivnosti daju bolje rezultate u mehanizmu za strukturiranje pokreta i reguliranju trajanja ekscitacije, posebno ako je usmjeren na razvoj biotskog motoričkog znanja. S druge strane, oni vjeruju da se u smislu diferenciranih programa tjelesnih vježbi za djecu treba pronaći novije i značajnije rjeenje, a samo takva rjeenja mogu dovesti do kvalitativnih promjena u strukturi izoliranih faktora.Ključne riječi: kinezioloke aktivnosti; motoričke sposobnosti; predkolska djeca; razlike; usklađenost faktorskih zasićenje.

The aim of the study was to analyze if there is a connection between some anthropometric measrements and a test for assessing aerobic ability in footballers of different age categories. 65 players were subjected to these measurements, of which 25 players aged 13-14 years (pioneers); 20 players aged 15-16 years (cadets) and 20 players aged 17-18 years (juniors). By using standard anthropometric instruments, body height, body weight, median volume of the chest and aerobic endurance were measured using a 20m “shuttle run” test. Using linear regression analysis, it was found that there is no statistically significant effect of anthropometric variables on a variable (20m “shuttle run”) of all three age players. In these ages, obviously some other characteristics have more influence on the manifestation of aerobic ability. The results of the research can be used by experts in the field of sports in further planning and organizing training contents
