Lifestyle and opportunities, for physical exercise at school and in free time, of female and male pupils attending the first four grades of primary schools in rural and urban areas, have indicated the need to establish the structure and the differences of anthropological features of male and female pupils in primary schools in urban and rural areas of Lika. The aim of this research was to apply the set of 37 variables and tests of motor and functional abilities on the subject sample of 800 participants (400 female and 400 male pupils) aged 7-10 attending the first four grades of primary schools in rural and urban areas in order to determine the differences in manifest and latent measures of anthropometric features between those two groups. The expediency of this work is to provide optimal, fast and effecient way to shape, diagnose, plan, programme and control physical activity among female and male pupils atttending the first four grades of primary schools in rural and urban areas. The set of morphological anthropometrical features used in this research was selected and measured according to the procedures prescribed by International biological programme, IBP-Weiner and Lourie, 1969. The sample of variables consists of 19 measures to estimate morphological measures. Longitudinal skeleton dimensionality was estimated by five measures: Body height (ALDTV), Arm length (ALDDR), Leg length (ALDDN), Foot length (ALDDS) and Biacromial range (ALDBR). Body volume and mass were estimated by five measures: Body weight (AVMTM), Central chest extent (AVMSOK), Upper arm extent (AVMONA), Upper leg extent (AVMONAT) and Lower leg extent (AVMOPOT). Subcutaneous fat tissue was estimated by four measures: Back skinfold (APMLE), Belly skinfold (APMTR), Upper arm skinfold (APMNAD) and Lower leg skinfold (APMPOT). Transversal skeleton dimensionality was estimated by five measures: Elbow diameter (ATDLA), Wrist diameter (ATDRZ), Bicristal range (ATDBKR) , Knee diameter (ATDKO) and Foot width (ATDST). The set of motor abilities' tests consists of 18 tests. Agility was estimated by three tests: Side steps (MAGKUS), Doing the 8 with bending (MAGOSS) and Carrying over by running (MAGPRP). Explosive strength was estimated by three tests: Standing long jump (MESSDM), High start 20 m sprint (MESS20) and Throwing medicine ball (1kg) from lying down (MESBML). Flexibilitiy was estimated by three tests: Forward bend with legs widely spread (MFLPRR), Forward bend on a bench (MFLPRK) and Forward bend with legs slightly spread (MFLPRU). Coordination was estimated by three tests: Ground practice backwards (MKOPLN), Rolling a ball by undominant hand (MKOKLR) and Ground practice with a turn (MKOPLO). Repetitive strenght was estimated by three tests: Lifting the upper body from lying down (MRSPTL), Lifting the upper body – short (MRSPTK) and Squats (MRSCUC). Balance was estimated by three tests: Standing on one leg on a balancing bench with eyes closed (MBAU1Z), Standing on a balancing bench with eyes open (MBAU20) and Standing on a turned over balancing bench with eyes open (MBAOKO). The collected data were processed by descriptive analysis; metric caracteristics of morphological features and motor abilities tests, were verified. Differences in manifest variables of morphological features and motor abilities tests, between female and male pupils attending the first four grades in rural and urban areas, were determined by discriminanat analysis. Defining latent dimensions of measures of morphological features and tests of motor and functional abilities of female and male pupils was conducted by factor analysis, the method of main components according to Guttman Kesir's criteria. The differences in latent dimensions, between female and male pupils in the first four grades of primary schools in rural and urban area, were determined by dicriminant analysis. The results have shown the existance of significant difference among female and among male pupils in manifest measures of anthropometric features and tests of motor abilities. Based on the collected data in manifest measures of morphological antrhropometric features, the first grade male pupils are best determined by discriminant function skeleton dimensionality and volume, and female pupils by subcutaneous fat tissue. The second grade male pupils are best determined by subcutaneous fat tissue, and female pupils by discriminant function of transversal skeleton dimensionality and volume. The third and the fourth grade male pupils differentiate in the function of transversal skeleton dimensionality, the third grade female pupils in the function of subcutaneous fat tissue and the fourth grade female pupils in soft tissues function. In the field of motor abilities the first grade male pupils are best determined by discriminant function of side agility, and female pupils by discriminant function of repetitive trunk strenght and coordination. The second grade male pupils are best determined by discriminant function of repetitive strenght and balance, and female pupils by upper extremities coordination and explosive leg strenght. There are not any significant differences between third grade male pupils, while female pupils show differences in repetitive trunk strenght. The fourth grade male pupils show differences in explosive strenght of lower extremities and agility, and female pupils in trunk strenght. By analysing latent dimensions in the field of morphological antrophometry, three basic components are extracted between the first grade female and male pupils, among which the first component is the biggest and the most explicable. The first basic component extracted among female and male pupils is subcutaneous fat tissue. The second extracted component among male pupils is longitudinal and transversal skeleton dimensionality, and among female pupils longitudinal skeleton dimensionality. The third extracted component among female and male pupils is transversal skeleton dimensionality and body volume. Three components were calculated in the second grade. The first basic component among male pupils is transversal skeleton dimensionality and body volume and among female pupils it is the soft tissues component. The second and the third extracted components among male pupils are subcutaneous fat tissue and longitudinal skeleton dimensionality, and among female pupils it is longitudinal skeleton dimensionality and transversal skeleton dimensionality. The first basic component of soft tissues and transversal skeleton dimensionality is extracted among the third grade male pupils and the components of subcutaneous fat tissue, transversal skeleton dimensionality and body mass among female pupils. The second component among female and male pupils is longitudinal skeleton dimensionality. The third extracted component among male pupils is transversal skeleton dimensionality and among female pupils body volume. Three basic components are extracted among fourth grade male pupils, and among female pupils, two. The first basic component among male pupils is soft tissues component and among female pupils in this grade there is also transversal skeleton dimensionality. The second and the third component among male pupils is longitudinal skeleton dimensionality and transversal skeleton dimensionality and among female pupils they are united in the second component. In the field of motor abilities of female and male pupils in the first grade, six i.e. five basic components were extracted. The first basic component extracted among male pupils is repetitive strenght, agility and explosive strenght of lower extremities, and among female pupils coordination and agility. Extracted components among male pupils are: lower back flexibility and back thigh flexibility, closed eyes balance, opened eyes balance, coordination, repetitive body strenght, body coordination and explosive leg strenght, upper extremities coordination. The first extracted component among male pupils in the second grade is agility and explosive leg strenght and among female pupils coordination and agility. Extracted components among male pupils are flexibility, balance, repetitive leg strenght and body coordination, closed eyes balance and among female pupils: flexibility, repetitive leg strenght, explosive leg strenght, balance, repetitive strenght and agility. The first basic components extracted among the third grade male pupils are agility, coordination and explosive leg strenght and among female pupils agility, explosive leg strenght and coordination. The extracted componenets among male pupils are: flexibility, explosive arm and shoulder strenght, balance, closed eyes balance and repetitive strenght. The extracted components among female pupils are: flexibility, closed eyes balance, opened eyes balance, explosive arm and shoulder strenght. The first basic component extracted among the fourth grade male pupils is body coordination and among female pupils in this grade the extracted components are agility, coordination and explosive leg strenght. The extracted components among male pupils are: flexibility, explosive leg strenght, repetitive leg strenght and agility, explosive arm and shoulder strenght and balance. The extracted components among female pupils are: flexibility, balance, repetitive trunk strenght, repetitive arm and shoulder strenght. Pupils from the first to the fourth grade are best determined by discriminant function of longitudinal and transversal skeleton dimensionality in latent dimensions of morphological anthropometrical features. The first grade female pupils are best determined by discriminant function of subcutaneous fat tissue, the second grade female pupils are best determined by discriminant function of transversal skeleton dimensionality and the third grade female pupils by discriminant function of subcutaneous fat tissue and transversal skeleton dimensionality. The fourth grade female pupils are best determined by longitudinal skeleton dimensionality. Values of discriminant analysis in latent motor abilities of the first grade pupils indicate that there are not any statistically important differences. Pupils in the second grade are best defined by discriminative function of balance. There are not any statistically important differences between pupils in the third grade. In the third grade there are not any statistically significant differences among pupils in the defined latnent motor factors. In the fourth grade pupils are best defined by the discriminative function of explosive leg strength. In the first grade female pupils are best defined by the discriminative functions of coordination and agility and coordination of upper extremities, while in the second grade there are not any statistically significant differences. In the third grade female pupils are best defined by the discriminative function of opened eyes balance and in the fourth grade female pupils are best defined by agility, and explosive leg strength. Based on the given results, it can be concluded that primary school pupils attending the first four grades show statistically important differences in manifest measures of morphological features. The first grade male pupils are taller and show higher measures in values, while male pupils from rural areas are, in higher classes, shorter and more robust with more subcutaneous fat tissue. As far as motor abilities are concerned, the first grade male pupils from urban areas achieve better results in agility and explosive strenght tests, while higher grades male pupils from rural areas achieve better results in flexibility, repetitive and explosive strenght and agility tests. Female pupils from rural areas attending the first three grades are more robust and shorter with more subcutaneous fat tissue, while female pupils from urban areas suddenly step into the period of pre-puberty in the fourth grade. Female pupils from rural areas achieve better results in explosive and repetitive strenght and coordination tests, while female pupils from urban areas achieve better results in agility tests. Differences among female and male pupils are also confirmed in latent dimensions of morphological features and motor abilities. The first grade pupils show higher values of longitudinal and transversal skleton dimensionality, while in higher classes male pupils from urban areas show higher values of longitudinal skeleton dimensionality; pupils from rural areas show higher values of transversal skeleton dimensionality. Male pupils from urban areas achieve better results in latent dimensions of explosive strenght and coordination while male pupils from rural areas achieve better results in latent dimensions of balance, repetitive strenght and flexibility. Female pupils from rural areas attending the first four grades show higher values in latent dimensions of subcutaneous fat tissue and transversal skeleton dimensionality; and female pupils from urban areas attending the fourth grade show higher values in longitudinal and transversal skeleton dimensionality. These female pupils show better results in latent dimensions of motor coordination tests, agility and closed eyes balance, in lower grades. Female pupils from rural areas attending the fourth grade show better results in agility tests, explosive and repetitive strenght and coordination.
