On sample of 757 pupils, 379 boys and 378 girls, school age from 3rd to 6th class, nutrition status, acoording BMI, and motor status were analyzed by using 8 variables (3 for valuation of morphological and 5 for evaluation of motor abilities status). In the overall sample, 66.3% established a normal nutritional status 18.4% was overweight, 15.3% were obese. Obesity is the most vulnerable children in third grade (21.8%), and overweight in fourth (20.1%) and fi fth (20.9%) grade. The results indicate a statistically significant difference between the third and sixth grades, and no statistically significant differences in the frequency of overweight and obesity in all grades, or in relation to sex. Overweight has a negative correlation with explosive leg strength and muscle strength of arms and shoulders, while obesity has a negative correlation with the strength of muscles of arms and shoulders, running speed, strength of trunk muscle and explosive leg strength. Significant statistical relation was lacking in flexibility. The results show a statistically significant difference in the speed of running, muscle strength of arms and shoulders, trunk muscle strength and explosive leg strength between the overweight and obese pupils. A significant difference was not observed in the test to assess the value of flexibility. Generally, children who are overweight and obese have significantly reduced motor skills compared to normal children too soon, especially with regard to the manifestation of strength and speed.

The aim of this study was to define the actual model of body composition status of working age women in the territory of Belgrade. The sample comprised 109 women respondents, of an average age of 35.2±9.5 and the length of service = 9.6±9.3 years. All measurements were performed in the period from 2011–2012 in the Teaching-research laboratory of the Faculty of Sport and Physical Education of the University of Belgrade, by applying standardised procedure of electrical multichannel bioimpedance method. The researched encompassed twenty-two (22) variables – fourteen basic (14) and eight (8) derived (index) variables. Basic variables were: BH – body height, BM – body mass, ICF – intracellular fluid, ECW – extracellular fluid, TBW – total body fluids, Proteins, Minerals, BMC (Osseous) – bone mineral contents, BFM – total body fat mass, SMM – skeletal muscle mass, VFA – visceral fat area, BCM – body cell mass, BMR – basal metabolic rate, FIS – fitness score as assessment of body composition. The derived (index) variables were: BMI – body mass index, PBF% - percent of body fat, PBW - percent of body water, PFI - protein fat index, PSMM – percent of skeletal muscle mass, SMMD – skeletal muscle mass density, OBMi – Osseous-body mass index, PBMi – protein body mass index. The results showed that the average body mass of the respondents was 67.66±13.39 kg, body height 167.04±6.62 cm, body mass index 24.27±4.66 kg/m2, muscle mass 26.55±4.46 kg, muscle mass percentage 29.09±8.47, body fat mass 20.52±9.74 kg, body fat percentage 29.09±8.47, visceral fat area was 77.92±40.23 cm2 and fitness score 73.23±6.75 of index points. The obtained results led to the conclusion that the current morphological status of the studied women partially corresponds to a type of normal weight. BMI and the representation of body fat had nearly limiting values towards obesity. A very high percentage of women was recorded in the category of pre-obese and obese according to BMI (40%) and PSMM (36%). Based on the results of this study, it can be claimed that the four-dimensional model (4D model) of body composition of working-age women from the measured sample has the following characteristics: in women of average body mass of 67.66 kg – water content is 34.58 L or 51.11%, protein mass is 9.25 kg or 13.68%, mineral mass is 3.30 kg or 4.88% and fat mass is 20.25 kg or 30.32%.

Purpose of the present study was to examine whether influence of relative age effect (RAE) exists or not in the selected 13 year old basketball players. Subjects were 20 basketball players (HT=177.35cm±6.73, BW=61.42kg±8.98, average age 13 years and 7 months ±.28, average experience in basketball training 4 years and 6 months ±1.15). Sample was divided in two groups: 11 players born in first half of the year and 9 players born in the second half of the year. One-way ANOVA was used in order to analyze the differences between the two groups of players in set of anthropometric variables (body height, arm span, standing reach height, body weight and percentage of body fat), motor variables (velocity of neuromuscular reaction time, vertical jump, 5 meters sprint, 10 meters sprint, 20 meters sprint, T-test, Zig-zag test, ball throw from sitting position, Sit-ups for 30 seconds and standing forward bend) and one functional variable (20-M shuttle run test). Subjects do not differ in applied set of parameters, except in on variable (sit-ups for 30 seconds, p=.040). It was concluded that RAE does not exist in this sample of examinees.

indent Abstract
This paper contains a comparative analysis of competition routines with a hoop, ball or rope of the top six competitors at the World Championship in Moscow 2010 and the top six competitors at the Serbian Championship in Belgrade 2010. This analysis was conducted on the basis of the proportion of body difficulties from various structural groups (leaps, balances, pirouettes, flexibilities and waves) comprised within the routines of the competitors with corresponding apparatus (hoop, ball, rope) in both championships. The aim of this research was to identify the similarities and differences in the structure of leaps, pirouettes, balances and elements of flexibilities and waves of the first six competitors in both championships by analyzing their routines on video recordings. The findings discovered that the competitors in the World Championship demonstrated a considerably higher level of technical value in their routines compared to the Serbian competitors. The competitors at World level perform difficulties of greater average difficulties from all structural groups in their routines with a hoop, ball and rope and these differences are generally important from a statistical point of view. The greatest differences were noticed in pirouettes, whereas differences in the structure of flexibilities were the least, compared to other structural groups.

indent Abstract
Basic ideas and characteristics of fundamental falconry are disseminated also in the Kingdom of Serbia, ideas of fellowship, releasing of Germanization influence and strengthening of national and cultural conscience. Gymnastics associations accepted the idea of overall Slavic falconry exercising, and added to their names title "Falcon", as in Czech Falcons, and introduced Czech "Falcon" exercising system, instead of German one. Also Smederevo Gymnastics and Combat Association in the course of time chose the falcon exercising system. The aim of this research was to find, systemize and critically analyze data about the falconry in Smederevo, about the falcon association "Dusan Silni" (Dusan the Mighty), which as a successor continued the activities of the previous association – Smederevo Gymnastics and Combat Association. The basic assumption was founded on the expectation that data from the archive, periodical sources and ex falcon legacy would provide a satisfying base for reconstruction of Falcon Association history, i.e. appearance and development of the Falconry in Smederevo. During the research historic, causal and descriptive methods were used. Research results for the reference period, show that despite complex political, social, economic and cultural situation in the Kingdom of Serbs, Croats and Slovenes and the Kingdom of Yugoslavia, the Falcon Association of Smederevo played a significant role in spreading and development of the falcon movement and promotion of Yugoslav national thought. Large number of data showed that activities of this falcon organization were extremely versatile. Well organized training programs, numerous participation in falcon rallies and competitions, as well as health, educational, cultural and other forms of acting of the Association, had great influence on social and cultural transformation of the town of Smederevo as well as of the nearby villages and rural population, for which falcon foremen took most credit.

Aims: This study examined the relationship between Olympic years and leisure-time physical activity levels across Canadian provinces and territories, as well as between genders. Methods: Analysis of long-term regional and national data on physical activity patterns confirmed that average activity rates were significantly higher (X2(1) = 8.52, p < .01) for Winter vs. Summer Olympic Years. Results: Results indicate significant long-term temporal, sex and geographic trends which establish a reoccurring increase in physical activity amongst moderately active Canadian males (leisure-time physical activity rates were somewhat lower amongst females) across all provinces and territories during Winter Olympic years. This suggests that the Olympic Games, particularly the Winter Olympics, may act as a catalyst for increasing Canadian leisure-time physical activity rates - predominately amongst males. Subsequently, this paper recommends that greater media campaigns be directed toward Canadian females in an attempt to increase their leisure-time activity levels. Furthermore, greater emphasis should be placed on providing fitness programs for employees at their workplace - facilitating ease and convenience for increased leisure-time physical activity in general.

The primary goal of this paper is to show the capacity of the program content of physical education in the implementation of the third specific objective of the Framework Action Plan for the Prevention of Violence in Educational Institutions. Ministry of Education brought this plan in January 2009. The third specific objective of the Framework Action Plan: Provide preventive and protective role of school sport and sporting activities of students. This paper examines the extent to which this goal is achieved, trough regular classes, after-school and extracurricular activities of physical education; indicates the capacity of the teaching field in the creation and development of a safe and supportive environment in the institution; sees level of participation by experts, council and teams in the design and implementation of sports activities in school and the extent to which these activities are implemented in the institution documents, plans and programs of experts, and larger teams; it is the sustainability of these activities achived in school practices and also to strengthen the competence of teachers in supporting the development of students personality, communication and collaboration. In order to complete document association of council, experts and teams in the institution, there has been an insight into the school curriculum, the development plan, annual plan of the institution, protection program community of students, the curriculum of a school parliament, council of parents, higher vocational and physical education teachers and report on the implementation of the protection program. In order to document by empirical data the capacity of the teaching areas in the function of preventing violence, a sample of 46 primary schools in Sumadija area, evaluation of the implementation of sports and sports activities students in programming classes of physical education, was executed. By these results, it can be concluded that in teaching methods is not fully brought to life to use programs of physical education in the development of a safe and supportive environment in the institution. School program as a background document does not contain possible extra-curricular and after-school activities in the programming of physical education, which realization would explicitly encouraged the construction of a safe and secure environment in the institution. Annual plans of theinstitution does not include the activities of The Framework Action Plan for the Prevention of Violence in Educational Institutions. Plans and Programs of the Students' Parliament and the Parents Council does not consider and suggest sports activities that are directed toward creating a safe environment in the institution. Team for students safety in their prevention activities did not recognize the importance and contribution to school sport and recreational activities in creating a tolerant atmosphere. Expert council of physical education teachers is failing to implement school sport and sporting activities and effectively integrate and link them with a team of student safety within a school in order to prevent violence at the facility and at sport events. Sustainability of these activities in practice is not achieved.

Primary objective of this study was to provide the insight into the effects of strength training on the testosterone (TE) level in men, as well as the mechanisms of anabolic effects of testosterone on human muscle apparatus, since it is known that one of the ways to increase muscle strength is through the increase of muscle mass (peripheral factor), and the basis of this process is the effect of TE. The collected data summarize the conclusions of a number of previous studies, out of which larger number of recently, and they relate to the effect of different methods of strength training (H - submaximal effort to failure, S - maximal effort, P - dynamic effort) with equally applied total volume of load, and the effect of different rest periods in strength training on the level of TE in men. The presented results confirmed the claims that the H method is the most effective and reasonably called 'the method for muscle hypertrophy'. When it comes to rest periods, the ones that last for about 90 seconds proved optimal because this period had most influence on the level of lactic acid and catecholamines in blood which are considered to be the key factors for the increased secretion of TE (this hormone was included in a group of stress hormones as well) However, according to many authors, further examinations in this field are necessary in order to determine the causal link with greater certainty.

Planning and programming are the basis of every coach, regardless of his experience and knowledge. Plan and program are the basic document used for realization of the process of the sports preparation and control effects achieved by their implementation. Planning and programming are impossible to determine without a certain degree of precise school of volleyball, while the schedule of goals and tasks for each level is going to determine the curriculum of a given degree. This study is about annual planning and programming for the first level of volleyball school for girls, aged 8 to 10 years. The aim is to define the tasks of volleyball school for first degree, to make the annual plan of training volume and determine the annual program of sports preparations.
