There was lot of previous researches about achievement motivation, but also not lot of comparisons between young footballers and nonfootballers. This article intends to improve psychological way of working with young sportsmen and help to coaches how to approach in positive way to young person. The main objective of this research was to determine the differences in the level of achievement motivation at boys age 10-14 years (N=200) in relation with sport status, school success and economic characteristics who were divided into 2 subsamples: who are/or not engaged in football. In this study, for data collection the MOP2002 scale was used (Franceško, Mihić, & Bala, 2002). For the purpose of data processing in this study were used methods of descriptive and multivariate statistics (t-test, canonical discriminant analysis, F-test). Application of canonical discriminant analysis which showed that the discriminating canonical correlation function of 0,39 (λ= 0.86; χ2 = 22.40; r = 0.00), which means there is a statistically significant difference regarding the structure of the achievement motivation. The results of the research indicate that engagement in football by an individual causes the higher level of the achievement motivation, with the most pronounced contribution by the component “persistence in achieving goals”, and then “goals achievement as a source of satisfaction”. Also, the  results show that the economic status of the family didn’t contribute to differences in achievement motivation of their children, and difference in the school success of the respondents is followed by level of its motivation. 

All physical activity of preschool children during the day occurs while they are in kindergarten or during their leisure time. The aim of the study was to present the results related to the participation of children in organized activities during leisure time and what is the perception of parents about the scope of their children's physical activity and the time spent on watching TV, using computers and playing video games (as a part of wider study). The research was conducted in 2017 in the Preschool institution “Naša Radost” in Subotica. The survey questionnaire was filled in by 135 parents for children of the average age of 5.14 years (±0.91). The survey questionnaire contained questions about children's nutrition (NutriStep survey) and their involvement in organized activities with educational and sports-recreational content during leisure time, as well as parent’s opinion on quantity in child’s sedentary activities. 65.9% of children aged 5 to 7 was found to attend some kind of organized activity, most often within programs of foreign language schools, sports schools and programs with aesthetic  presentation of skills is important (ballet, dance and folklore). The largest number of parents reported that their child spent one hour watching TV, using a computer or playing games. About 71% of parents reported that their child was physically active enough. In both cases, a statistically significant difference was found between boys and girls. Within the family circle and within the educational institution, where children spend most of the time, it is necessary to provide conditions for undisturbed growth and development. One of the best ways is through exercising physical activity. 

The lack of common rules and credible judgement created particular problems gymnastics competitions, organized by the two international sports institutions (IOC, EG), until the beginning of the World War I. After the end of the war, these institutions began to cooperate, to widen and to put under their aegis all the existing Gymnastics Federations. In the decades of 1920 and 1930 totally five International Gymnastics competitions were organized by the IGF and five Olympic Games by the IOC. Despite the considerable efforts of the two institutions for commonly accepted regulations, reliable judgment and uniform apparatuses, no solution was found. So, there were a lot of problems, since several federations were introspective and followed their own regulations and principles. This fact affected negatively the general development of gymnastics.

The purpose of this study is to research and show off the structures and characteristics of the regulations of gymnastics in the decades of 1920 and 1930 as well as the reasons that caused the lack of common rules and their effects in the development of gymnastics.  

Lately, there has been increase of interest in examining the motives of male and female adolescents for taking part in physical activities, as well as examining their depression, anxiety and stress. The objective of this paper was to investigate intergender differences between male and female adolescents concerning the motives for physical exercise, depression, anxiety and stress. The pertinent sample accounted for 332 high-school students of both sexes from Valjevo (164 females and 168 male high school seniors), aged 18.10 ± 0.86. Three measuring instruments were used: Questionnaire for collecting basic data, The Exercise Motivation Inventory 2 („EMI–2“) questionnaire and the Depression anxiety stress scale (DASS – 21). The internal consistency and reliability of the questionnaire and the scale was satisfactory. The given results revealed that there are statistically significant gender differences, as the male adolescents, compared to the female adolescents, more frequently took part in physical activities (p ≤ 0.01). The important difference between the motives for participating in physical activities between the male and female participants was defined, so the motives: Socializing, Competition, Enjoyment, Social recognition and Strength and Persistence were more dominant with male adolescents, whereas motives: Appearance, Agility, Maintaining and improving health, and Body mass control were manifested more with female high school seniors. The findings revealed, with the probability of error being 0.05 the statistically significant differences of the depression dimension between the adolescents who rarely or never take part in physical activities and those who take part in physical activities three or more times a week. The results suggest that there are significant differences between male and female participants when it comes to stress variable (t = -2.47, p ≤ 0.01) and anxiety variable (t = -2.17, p ≤ 0.05). Differences on the depression variable are not significant. The findings were discussed within the context of current empirical and theoretical frame. 

Although beach handball comes from the sport that is played indoors it has significant differences from it. The aim of the study was to investigate and compare tactical options in both defense and attack between men and women. In 16 games from 2017 European Beach Handball Championship, 1074 attacks and defense situations were analyzed, in order to examine different attack and defense tactics. The selected method was video-analysis. The ꭓ2-test was used to compare the differences between the formations in defense and attack. In defense the results showed that men use more often 3:0, 2:1C and 2:1L formations, while women use more often 3:0. From the comparison between men and women it appeared that, in the initial formation of defense, there are significant differences, while in the final tactical formation are minimal. Men, in the initial and final tactical option in attack, used the system with one pivot and the specialist in center. Women use the same formation but also the one with a pivot and specialist at the left side of the attack at the substitution area. In the initial attack formation, appeared few significant changes between men and women, while in the final tactical formation there were no changes. Finally, the final throwing attempts, men choose to make them mainly from the center while women from the right and from the center. In conclusion, we can say that men’s and women’s tactical choices in defense and offense show some differences, but these differences are small. 

In the history of human kind in all ethnic groups and communities there have been individuals with physical or mental disabilities. Until the 18th century not only these individuals did not receive any support or care by their community but they were rather treated as inferior with a diminishing way. More or less the same attitude occurs to the ancient Greek world, where old age, limited psychomotor skills and potential disability were perceived as evidence of deprivation of the grace of gods. A minor acknowledgment of individuals with disabilities started from Athens, since there were several benefits introduced on behalf of the disabled for the very first time in the history of human kind. In the ancient times Greeks made use of physical exercise as a mean for therapeutic as well as prevention purposes against various diseases. Thus, a great number of distinguished physicians such as Herodikos and his student Hippocrates recommended physical exercise as the ideal treatment of several health-related problems. 

The aim of this research was to determine the differences in health-related fitness between preschool children involved in organized and unorganized physical activities. This study was performed on a sample of 220 healthy preschool children that were divided into two groups, organized physical activity group (N=99) and unorganized physical activity group (N=121). Beside the set of anthropometric variables children were tested for Standing broad jump, Classic sitand-reach test, Bent arm hang, Sit-ups in 30 seconds and Handgrip strength test. The t-test applied to determine differences between anthropometric characteristic revealed differences for almost all variables (p≤0.05). Moreover, the organized physical activity group showed better results in all fitness variables compared to unorganized group (p≤0.01). It can be concluded that the developmental gymnastics program has influence on improvement of health-related fitness in preschool children.

The aim of this study was to determine the relations between morphological characteristics and specific motor skills of karate athletes, where by the obtained results would be used in better planning and programming of training. Twenty-five young adults karate athletes (15.32 ± 0.22 years) members CC “Šotokan” from Loznica with a sports experience of not less than 8 years participated in this study. The research involved the measurement of certain morphological characteristics and specific motor skills of forward hand punch and foot strikes using standardized tests. The application of the regression analysis showed that there is a statistically significant influence of the system of predictor variables on the criterion variables (p≤0.05) reverse punch - gyaku-zuki (P=0.00), lunge punch - oi-zuki (P=0.00) and front kick - mae-geri (P=0.01). The total variability ranged from 50% of the criterion of the front kick - mae-geri to 60% of the criterion of lunge punch - oi-zuki. The values of the standardized regression coefficient Beta indicate the individual positive and statistically significant influence of the body height and muscle mass variables on the criteria tested: gyaku-zuki, oi-zuki and mae-geri, and the negative impact of the body weight variable on the oi-zuki criterion (pβ≤0,05). A positive influence of the overall body water quantity variable on the gyaku-zuki criterion (pβ≤0,05) was also determined. It can be concluded that there is a connection between the morphological characteristics and the specific motor skills of junior-age karate athletes from Loznica. 

Nutritional status is a relevant indicator of optimal growth and development, as well as the health status of children. Since nutritional status can influence the expression of children’s motor capacities, a study has been carried out in order to examine differences in motor abilities of children in relation to their nutritional status. The sample included 300 first- and second-grade students (132 boys, 168 girls). Students’ motor literacy and motor ability status was evaluated by reduced version of “EUROFIT” test battery, while nutritional status was evaluated based on the body mass index. IOTF criteria were used in order to assign participants into four distinctive groups – underweight, normal weight, overweight and obese. Differences between groups in motor ability status were tested by Kruskal-Wallis and Mann-Whitney tests. No significant differences were found between groups of a different nutritional status in most of the motor abilities, suggesting that BMI does not represent a high-quality predictor of motor abilities of children of lower elementary school grades. 

The aim of this paper was to determine whether the high-intensity interval training (HIIT) training can improve aerobic fitness in regional-level soccer players. Billat method (30-30s and 15-15s; 6-12 min) was used twice a week for 8 weeks during a season. Twenty-Three National-level soccer team players, (years=25±8, height=183.28±5.93, weight=75.28±5.9), were recruited for this study. Pre- and post-experimental period, maximum oxygen uptake was measured thru pseudo-ramp test on treadmill until volitional fatigue. Obtained results showed improvement in aerobic fitness for post- vs premeasurement (initial measurement = 51.92±3.40, final measurement = 54.87±2.61, p<.001). It is likely that specific high intensity interval training is viable method for aerobic fitness improvements in national-level soccer players when conducted during season.
