The aim of this study was to investigate the influence of body composition on the anaerobic strength of the lower extremities, as well as the prediction of body composition on the results of anaerobic ability in professional football players. Materials and Method. The sample of respondents consists of female football players who compete in the highest rank of the competition, the Serbian Super League. The total number of respondents included in the study was 21 female football players (age 19.38 ± 3.69, body height 166.48 ± 6.17 cm, body weight 59.98 ± 7.09 kg). The study is of a transversal nature and testing was done in the pre-competition period. The sample of measuring instruments used in the research are body composition and assessment of anaerobic strength of the lower extremities. Assessment of body composition was performed indoors using a multifrequency bioelectric impedance (Inbody 770). Variables for estimating the anaerobic strength of the lower extremities were obtained using a bicycle ergometer (Monark 839E) in the Wingate Anaerobic Test. Results. The results of body composition show a statistically significant influence on the prediction of maximum anaerobic strength of the lower extremities in professional female football players (p < 0.05), as well as on the overall work in the anaerobic zone and the mean values ​​of anaerobic strength. Regression analysis of the influence of body composition on the parameters of maximum strength in (W/kg) and fatigue rate does not show statistically significant results. Conclusion. There is a statistically significant influence of body composition, such as: body weight, lean body mass (%), muscle mass in absolute and relative values, on the values ​​of maximum anaerobic strength, mean values ​​of anaerobic strength and overall work in professional female footballers.

Football is probably the most popular game around the world, having taken over the globe with 256 million registered players in 208 countries. The aim of the study was to determine the differences in motor and functional abilities between football players of junior and cadet age. The research included a sample of 39 football players of the Kicker Football Club from Kraljevo, divided into two subsamples: 20 football players of junior age of chronological age of 17 ± 0.6 years and 19 football players of cadet age of chronological age of 15 ± 0.6 years. The following tests were used to assess motor skills: Starting acceleration at 10 m, Starting acceleration at 10 m flying start, maximum running speed during the test at 10 m, maximum running speed during the test at 10 m flying start, Illinois Agility test, while the following tests were used to assess functional abilities: Maximum oxygen consumption and maximum heart rates. The results of the study indicate that statistically significant differences were recorded only in motor abilities. The emphasis on working with younger categories should be placed on the long-term development process, to enable better success in senior age.

As the main objective, this research work had to compare pre and post complex training effects on body composition in elite handball players in the Spanish 2nd Division. Eleven players were included in the study. Six of them formed an experimental group, and 5 of them the control group. They have undergone the complex training session which was done once a week. The following parameters were analyzed: BMI (Body Mass Index), somatotype, FM (Fat Mass), MM (Muscle mass), RM (Residual Mass), WHR (Waist to Hip Ratio), BM (Bone Mass). The results have shown that there was a not statistically significant difference after the 6 – week program neither in body composition and somatotypes. Since this program did not have a big influence on body composition we could say that complex training influences body composition should be further researched.

Sažetak: Za potrebe ovog istraživanja korišten je uzorak od 120 ispitanika -učenika osnovnih škola u Banjoj Luci, Istočnom Sarajevu, Nišu i Beogradu, hronološke starosti 11 i 12 godina ±6 mjeseci. Uzorak ispitanika podijeljen je na dva subuzorka. Prvi subuzorak (eksperimentalna grupa) obuhvatio je 50 učenika, koji su pored redovne nastave fi zičkog vaspitanja bili polaznici rukometnih škola i bili su obuhvaćeni precizno defi nisanim eksperimentalnim modelom rada bazične pripreme u trajanju od tri mjeseca (36 trenažnih časova). Drugi subuzorak (kontrolna grupa) je obuhvatio 70 učenika koji su bili angažovani samo u redovnoj nastavi fi zičkog vaspitanja. Istraživanje je izvršeno sa ciljem da se utvrdi da li će doći do statistički značajnih promjena nivoa motoričkih i situaciono-motoričkih sposobnosti na kraju eksperimentalnog tretmana kod mladih rukometaša i da li se eksperimentalna grupa u odnosu na kontrolnu grupu na fi nalnom mjerenju statistički značajno razlikuje u analiziranim sposobnostima. Analiza razlika između inicijalnog i fi nalnog mjerenja ispitanika eksperimentalne i kontrolne grupe utvrđena je primjenom t-testa, primijenjena je multivarijantna analiza varijanse (MANOVA) radi utvrđivanja postojanja statistički značajnih razlika između kontrolne i eksperimantalne grupe na inicijalnom i fi nalnom mjerenju. Dodatno je primijenjena i univarijantna analiza varijanse (ANOVA) s ciljem utvrđivanja statističke značajnosti razlika za svaku varijablu. Rezultati istraživanja ukazuju da je kod ispitanika eksperimentalne grupe na kraju eksperimentalnog perioda u odnosu na kontrolnu grupu došlo do statistički značajnog povećanja nivoa kod svih primijenjenih testova motoričkih i situaciono-motoričkih sposobnosti.Ključne riječi: specifi čni trenažni modeli, mladi rukometaši, motoričke i situaciono-motoričke sposobnosti UVODSvjesni smo da savremeno doba nosi sa sobom mnoge pozitivne promjene koje utiču na sam kvalitet života, ali isto tako pojavljuju se, kao posljedica ubrzanog tehnološkog razvoja i negativne konotacije. Prije svega misli se, na smanjenje fi zičkih, odnosno kretnih aktivnosti. Ova problematika nije nepoznanica, međutim godinama unazad akcenat je stavljan na neaktivnost odraslih osoba. Istraživanja u regionu, pa i kod nas skreću nam pažnju na mnogo značajniji problem, neaktivnost djece školskog uzrasta. Sve veća je prisutnost gojazne djece, kao i djece sa tjelesnim deformitetima školskog uzrasta, što je direktna posljedica smanjene kretne aktivnosti. Ako se uzme u obzir i činjenica da veliki procenat školske djece jedinu organizovanu fi zičku aktivnost imaju na časovima fi zičkog vaspitanja, stanje postaje još alarmantnije.Suočeni sa trenutnim stanjem, nemogućnosti povećanja broja časova fi zičkog vaspitanja i pomenutim problemom kod školske djece, preostaje jedino da se maksimalno ozbiljno pristupi problematici
