Objective: the aim of the research was to determine the differences in fitness components among children and adolescents from urban and rural areas. Design/method: A sample of 5076 school children (2877) and adolescents (2199) from urban and rural areas from the region of Strumica (Macedonia). Physical fitness is estimated with 7 tests and that: standing long jump, sit-ups, bent arm hang, handgrip, sit and reach, speedagility, shuttle run 4x10 and three-minute step test. The differences in fitness tests, anthropometric measures and body composition by place of residence were examined by one-way analysis of covariance. Results: Rural children and adolescent have lower height, body mass BMI and body fat % and had higher muscular mass % cardiorespiratory fitness and speed-agility (all p < 0.001), than urban young people. Regarding muscular fitness, the results differed depending on the fitness test selected. Rural children and adolescent had a better performance in standing long jump, handgrip strength bent arm hang while they had a lower performance in sit-ups in 30 s (all p < 0.001), compared to their urban peers. Effect size was small-medium (Cohen's d = 0.1-0.5). Conclusion: children and adolescents from the rural environment show better results in cardiorespiratory fitness, muscle fitness of the upper and lower extremities and have better coordination, speed and agility in comparison with their urban peers. The place of residence, apart from other environmental factors, should be taken into account when building a state strategy and interventions through which it will promote physical activity and health.
The aim of this study was to establish the anthropometric and physical profiles of young soccer players according to their playing position and to determine their relevance for competition success. One hundred and twenty young soccer players participated in the study. Players aged 19 were classified into the following groups: defenders (n=40), midfielders (n=40) and attackers (n=40). The anthropometric variables of participants (height, weight, body mass index, 4 skinfold, 2 diameters, and 2 perimeters) were measured. Also, their somatotype and body composition were calculated. Participants performed Bruce treadmill test protocol and Yo-Yo Intermittent Test to estimate their relative VO 2 max, sprint tests (5 m and 20 m flat), 2 jump tests (countermovement jump and standing long jump test), 3 tests for assessing agility (Illinois with balls and without balls, and 505-test) and seven fitness tests for assessing power, speed, agility, flexibility, frequency, abdominal muscle power and balance. Analysis of variance (ANOVA) was used to determinate differences between team positions. On the base of the obtained results, it can be established that players playing in midfield position have less body height, weight, and achieve less results in fitness tests Illinois 20-meter running, leg-tapping, sit-ups in 30 seconds, but better results in the tests 'sit and reach', 'flamingo' and the tests of assessing maximum oxygen consumption compared to the defenders and attackers. The attack players have less values in skinfolds and achieve better results in 5-meter running test and standing long jump compared to the midfielders and defenders. The obtained results can serve as normative morphologic-functional indexes for regular medical control of young footballers in the R. Kosovo. They can also be used as a model of comparison of morphologic-functional data between young footballers of similar levels in different countries.
The aim of this research was to determine the level of adiposity and obesity among Macedonian adolescents and to compare the results with previous studies conducted in this population, as well as those conducted in other populations. The sample included 2390 adolescents from four urban different regions of R. Macedonia aged between 11 to 18 years; 1238 males and 1152 females. Weight, height, waist, and hip circumference (WC, HC) as well as triceps, calf, subscapular, and suprailiac skinfold thickness (SFT) were measured. Body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), subscapular/triceps skinfold ratio (STR), and percentage body fat were computed. The prevalence of overweight and obesity defined by the IOTF children growth reference were calculated and age-dependent and gender-specific smoothed percentile curves for BMI and ROC curves were generated. The boys have statistically significantly higher values of WC, WHR and WHtR in all adult categories (except WHtR at 18 years old), greater body weight at the age of 12 to 18, and body weight 13 to 18 years (p<0.001). Weight, height and BMI are increasing with age in both, boys and girls, and decreases in girls. The level of adiposity of Macedonian adolescents has increased over the past 20 years and has reached the level of developed countries that face an obesity epidemic.
The knowledge of morphological development and their impact on motor skills in short-distance athletes should be one of the main concerns of athletics coaches, because any scientific research in the field of physical culture and sports is about proving the development and evaluation of anthropological characteristics which are responsible for achieving success in athletics. This paper explores the impact of some anthropometric features on running 200 meters. The aim is to establish the link between the anthropometric and specific characteristics of running 200 meters, as a predictive system of running at 200 meters as a criterion system. The research was conducted by 60 male students aged 17±6months, in the gymnasium "Zenel Hajdini” Gjilan. The measurements were executed during September in the hall of the gymnasium, while the 200, meter runs in the stadium "City stadium "Gjilan. The only condition that was used during the determination of the sample was: that the students are involved in regular physical education classes (and on the day of the measurement be healthy, without the flu, cold or other symptoms).The variables which are applied in this research have been 8 anthropometric variables and 1 motor-specific variables. The results obtained after their processing indicate that the impact of anthropometric variables is higher in running at 200 meters. Short distance running and long-distance running reduces the impact of anthropometric parameters whereas the influence of metabolic factors of energy production is increased. These results were also confirmed using regression analysis, so that groups of predictors of anthropometric characteristics, specific motor skills that statistically significantly influenced each variable of individual criteria. The world records below the 19.20-second limit, in the 200 m, near the 19-meter limit, show not only the high level of sports, but also the strong impact on the growth, especially of strength indicators, speed-strength, explosive force, as main and applied motor skills in sports and athlete’s everyday life.
To deal with sport activities, concretely with athletics, initially there should take place an early selection of children. Our search included 35 students’ athletes and 35 non athlete students. The overall number of 70 students of the age 15 were included in this research. There were applied 7 anthropometric variables, 6 motor tests and 2 motor specific tests as well. The main goal of this research was to determine the scale of difference between the two groups, respectively between the group of the non-athlete students and the one of the athlete students in some anthropometric characteristics, motor and specific motor as well. This work results show that training process within the frame of the athletics frame effects generally positively in positive development and transformation of human body in the aspect of morphological development, motor and specific motor aspects. All of it has been proved through reached changes of the students’ athletes group.
