In modern training technology, assessment of aerobic bioenergetic potential in athletes is commonly performed by standard laboratory procedures to determine basic or specific functional abilities for ...specific sport activity or discipline. The aim of study was to assess the aerobic bioenergetic potential of athletes participating in basketball, football and handball.
The study included 87 athletes (29 basketball players, 29 football players, and 29 handball players) aged 21-24. Evaluation of the aerobic bioenergetic potential of athletes participating in basketball, football and handball was performed followed by both univariate (ANOVA) and multivariate (MANOVA) statistical methods to determine differences among the athletes in relative (VO2 mL/kg/min) and absolute oxygen consumption (VO2 L/min).
Statistically significant differences between absolute and relative oxygen consumption were found in basketball players (Mb), football players (Mf), and handball players (Mh) (MANOVA, p = 0.00). ANOVA also revealed significant differences in relative oxygen consumption (VO2 mL/kg/min) (p = 0.00). The football players (55.32 mL/kg/min) had the highest relative oxygen consumption, followed by the handball players (51.84 mL/kg/min) and basketball players (47.00 mL/kg/min). The highest absolute oxygen consumption was recorded in the basketball players (4.47 L/min), followed by the handball players (4.40 L/min) and footballers (4.16 L/min).
Statistically significant differences in the aerobic bioenergetic potential, expressed by the relative oxygen consumption were found among atletes participating in different team sports. It can be assumed that the player from the sports in which it is necessary to cross greater distance in total during the match have a greater need for aerobic capacity.

A sample of 655 participants, schoolchildren aged 7 to 11, was included in a study of a system of 10 variables, with the aim of applying a multivariate analysis of variance and a canonical ...discriminant analysis to determine the statistical significance of the c4fferences in the means between the genders in terms of morphological characteristics and motor skills. By using a canonical discriminant analysis, we isolated a single discriminant function whose structure is made up of seven variables, six of which belong to the boys, and only one of which belongs to the girls. The changes are ones which are not genetically limited, that is, ones which are still susceptible to change, so as to be able to perform optimum planning and programming and the operationalization of physical education classes based on the obtained indicators, as well as the control of the onto-genetic development of these relevant anthropological characteristics, under the influence of the programmed contents according to gender at this age.Original Abstract: Na uzorku od 655 ispitanika (348 decaka i 307 devojcica), ucenika i ucenica od I-IV razreda osnovne skole, bio je primenjen sistem od 10 varijabli (4 morfoloske i 6 motoricke), sa ciljem da se primenom multivarijantne analize varijanse i kanonicke diskriminacione analize utvrdi statisticka znacajnost razlika u aritmetickim sredinama izmedu polova u morfoloskim karakteristikama i motorickim sposobnostima. Dobijeni rezultati su pokazali da u celom sistemu primenjenih varijabli postoji statisticka znacajnost razlika izmedu polova na nivou p=.00, a univarijantno, da su decaci, vrlo verovatno na racun povecane telesne tezine (p=.01) i obima podlaktice (p=.00), imali bolje rezultate i u motorickim sposobnostima eksplozivne snage (skok udalj iz mesta p=.00), koordinaciji teta (poligon natraske, p=.00), repetitivnoj snazi (podizanju trupa, p=.00) i sili (izdrzaj u visu, p=.00), dok su devojcice imale bolje vrednosti samo u fleksibilnosti (pretklon trupa, p=.00). Primenom kanonicke diskriminacione analize izolovana je jedna diskriminaciona funkcija (p=.00), ciju strukturu sacinjavaju sedam varijabli, od kojih sest pripadaju decacima, a samo jedna (pretklon trupa) devojcicama. Shodno dobijenim vrednostima, neophodno je da se u nastavi fizickog vaspitanja u ovom uzrastu kod oba pola mora u podjednakoj meri voditi racuna o razvoju (vecim promenama) morfoloskih karakteristika i motorickih sposobnosti, koji nisu geneticki ograniceni, odnosno kod kojih su moguce promene, kako bi se na temelju dobijenih pokazatelja moglo vrsiti optimalno planiranje, programiranje i operacionalizovanje razredne nastave fizickog vaspitanja, kao i kontrola ontogenetskog razvoja ovih relevantnih antropoloskih karakteristika pod uticajem programiranih sadrzaja po polovima u ovom uzrastu.
The aim of this research was to use a system of 37 variables of morphological characteristics on a sample of 108 elite male athletes (25 karatekas, 27 judokas, 19 taekwondoists, 18 boxers and 19 ...wrestlers), aged 17 to 23, to determine any statistically significant differences between the groups of athletes in terms of variable means, so that during the training process, the selection of athletes could be carried out in a proper and objective manner and that the training transformation processes could be managed more effectively. After processing the data using the statistical method of a multivariate and univariate analysis of variance (MANOVA/ANOVA), we obtained results that indicate that among the karatekas, judokas, taekwondoists, boxers and wrestlers in the entire system of (multivariate) morphological variables there is a statistically significant difference between the means (p=0.000). The results of the research have shown that what we are dealing with are different morphological structures of athletes involved in different sports. Since in the longitudinal and transversal dimensionality of the skeleton the values are more pronounced for boxers, wrestlers and karatekas, during selection it is necessary to be vigilant, since these are morphological characteristics which are genetically limited and can only change up to only 2% during the training process, while for voluminosity and body mass and subcutaneous fatty tissue there is the possibility of carrying out transformations of 2050%.

KEY WORDS: Males; Combat sports; Morphology; Comparison. El objetivo de esta investigacion consistio en utilizar un sistema de 37 variables de las caracteristicas morfologicas de una muestra de 108 deportistas de elite masculinos (25 karatekas, 27 judokas, 19 taekwondistas, 18 boxeadores y luchadores 19), de 17 a 23 anos, para determinar alguna diferencia que sea estadisticamente significativa entre los grupos de atletas en terminos de medios de variables, de modo que durante el proceso de formacion, la seleccion de los atletas podria llevarse a cabo de una manera adecuada y objetiva, y que los procesos de transformacion de la formacion podrian ser manejados de manera mas eficaz. Despues de procesar los datos mediante el metodo estadistico de analisis multivariado y univariado de la varianza (MANOVA/ANOVA), se obtuvieron resultados que indican que entre los karatekas, judokas, taekwondistas, boxeadores y luchadores en todo el sistema de (multivariable) variables morfologicas no existe una diferencia estadisticamente significativa entre las medias (p=0,000). Los resultados de la investigacion han demostrado que se observan diferentes estructuras morfologicas de los atletas que participan en diferentes deportes. Dado que en la dimensionalidad longitudinal y transversal del esqueleto y sus valores son mas pronunciados para los boxeadores, luchadores y karatekas. Durante la seleccion es importante estar atentos, ya que estas son las caracteristicas morfologicas que geneticamente son limitantes y solamente se pueden cambiar hasta el 2% durante el proceso de formacion, mientras que para la voluminosidad y la masa corporal y el tejido graso subcutaneo es posible efectuar transformaciones del 20-50%.

The aim of the research was to study the relations between morphological, normal and pathological conative characteristics of handball players of the Premiere Handball League of Serbia. The study was ...based on a system of 51 variables (23 anthropometric, 16 normal conative and 12 pathological conative variables). The data were collected on a suitable sample (N=71) and processed using a canonical correlation analysis. The results indicate that there is a canonical correlation between the systems of anthropometric variables and the system of normal conative characteristics (Rc =.80; p<.00), and that there were two statistically significant correlations between the system of normal and pathological conative characteristics (Rc =.69; p<.00 i Rc =.62; p<.02). The handball players of the ectomesomorph type are characterized at the one end with longitudinal measures and on the other with transversal dimensionality, the volume of the femoral region if they have increased values of conative variables, are extrovert and non-anxious. Among the handball players who are polite and considerate of each other there is an increase in the scores for depression as well as those which indicate a more pronounced vivacity and impulsiveness and expressiveness. Handball players who more frequently manifest dominant, competitive or even aggressive behavior are more anxious, while those who are more moral and adhere more to the rules are more prone to hypersensitivity. The ones who are undaunted and have an adventurous spirit score higher for obsession. Tense, energetic and impatient handball players often develop gastrointestinal conversion, hypochondria and phobias.
Cilj istraživanja je ispitivanje relacija morfoloških, normalnih i patoloških konativnih karakteristika rukometaša Prve rukometne lige Srbije. U istraživanju je primijenjen sistem od 51 varijable (23 ...antropometrijske, 16 normalnih konativnih i 12 patoloških konativnih varijabli). Podaci su prikupljeni na prigodnom uzorku (N=71) i obrađeni pomoću kanoničke korelacione analize. Rezultati pokazuju da između sistema antropometrijskih varijabli i sistema normalnih konativnih karakteristika postoji kanonička korelacija (Rc =0,80; p<0,00), a između sistema normalnih i patoloških konativnih karakteristika dobijene su dvije statistički značajne korelacije (Rc =0,69; p<0,00 i Rc =0,62; p<0,02). Rukometaši ektomezomorfnog tipa se karakterišu na jednom polu longitudinalnim mjerama a na drugom transverzalnom dimenzionalnošću obimom femoralne regije ako imaju povećane vrijednosti u konativnim varijablama, ekstraverti su i neanksiozni. Kod rukometaša koji su ljubazni i pažljivi prema drugima postoji porast skorova na depresivnosti kao i kod onih koji pokazuju izraženiju živahnost i impulsivnost i ekspresivnost. Rukometaši koji češće manifestuju dominantno, takmičarsko, asertivno ili čak agresivno ponašanje su anksiozniji, dok su oni koji su moralniji i više poštuju pravila su skloniji hipersenzitivnosti. Oni koji su neustrašiviji i avanturističkog duha imaju više skorove na opsesivnosti. Napeti, energični i nestrpljivi rukometaši češće razvijaju gastrointestinalnu konverziju, hipohondriju i fobičnost.
