There are numerous publications in the literature reporting physical development and motor performances of children of different ages based on sex and various environmental factors. However, there are not many publications on the birth season effect. The aim of the study was to evaluate the differences among children in physical development and motor performances based on age and birth season. Physical development described by body height and body weight, in addition to motor performance indicators including the twenty-metre dash, standing broad jump, six minutes of continuous running, throwing with a stuffed ball, and obstacle race-tests were studied. The survey included the participation of 426 girls. From the group the seven-, eight-, and nine-year olds numbered 148, 191, and 87 respectively. The group of girls who were born in winter, spring, summer and autumn numbered 114, 110, 89 and119 respectively. The tested data were evaluated with unitrate analyses of variance using SPSS statistical package. Mean value, standard error, standard deviation and coefficient of variation were calculated. The significance of differences between mean values was evaluated using “t” test. Differences with an error below 5% were considered to be significant. Furthermore, a correlation analysis was used to evaluate the relationship between season of birth, body development and motor-related performance data. Age, body height, body weight, throwing a stuffed ball in one hand, twenty-metre dash, six minutes of continuous running, and obstacle race-test are interdependent variables of development and motor performances of young girls of this age. Data from the study results show that the children group included in the tests was quite homogenous in body height, but heterogeneous in body weight and motor performances. Physical development and four of the five evaluated sport skills were affected by the birth season. Development and motor performances of the summer- and autumn-born girls are generally better than those born in winter or spring. Differences are significant except for the obstacle race-test. Age, body height, body weight, throwing with a stuffed ball in one hand, twentymetre dash, six minutes of continuous running, and the obstacle race-test seem to be interdependent variables of development and motor performances of young girls of this age.

Aim. To investigate physical development of children in Voronezh region in different age groups in 2011-2014 in comparison with the regional studies data in 1997-1999. Methods. The study was performed on 5644 children aged 1-18 years of health groups I and II in comparison with the data of 10 247 children aged 1-14 years examined in 1997-1999. Body height, weight and body mass index Z-scores, calculated using WHO AnthroPlus software, were evaluated. Results. Children’s Z-score values for body height in 2011-2014 were higher than in 1997-1999 in all age groups and at the age of 1-9 years these values exceeded World Health Organization (WHO) standards. Girls’ height approached the standards in 10-14 and 15-18 years, and boys’ height - in 15-18 years. Body weight of children aged 2-8 years was higher than the regional data in 1997-1999 and WHO standards approaching them at the age of 9. Body mass index increase compared to WHO standards was revealed in children aged 1-4 years (p=0.000), and in 2011-2014 the reported differences were less prominent than in 1997-1999. In 2011-2014 among 15-18-years-old girls the shift of body mass index values to the lack of body weight was noted, in 1997-1999 the same changes were found out for 10-14-years-old girls. Conclusion. In 2011-2014 specific attention was required to be paid to physical development of children at the age from 1 to 4 years due to overweight risk of and girls aged 15-18 years due to probable underweight risk.

Glycosaminoglycans are natural components of healthy joint cartilage and they also appear in healthy synovial fluid. An increased amount of glycosaminoglycans in synovial fluid is believed to be a marker of secondary osteoarthritis, regardless of its primary cause. The aim of our study was to define the relationship between glycosaminoglycans in the synovial fluid and joint disorders, age, and body weight. The samples of synovial fluid were obtained from dogs suffering from secondary secondary osteoarthritis (n = 35) and from control dogs (n = 18); control dogs had normal body weight. The results were compared among joints of dogs with secondary osteoarthritis divided into groups according to the criteria mentioned above and control dogs. Glycosaminoglycan concentrations in synovial fluid were measured using dimethylmethylene blue assay. The lowest mean value of glycosaminoglycans in synovial fluid was measured in the control group. Significantly higher glycosaminoglycan content (P < 0.05) was found in synovial fluid isolated from obese dogs compared to control dogs. Furthermore, we observed an age-related trend, in which the highest mean values were reached either in old dogs or pups. Despite the absence of significant differences in glycosaminoglycan values among dogs suffering from various types of secondary secondary osteoarthritis, the highest mean values were measured in fragmented coronoid processus group. Our data suggest that abnormally increased body weight has an impact on glycosaminoglycan concentration in synovial fluid which may imply faster degradation and turnover of joint cartilage. Such observation has not yet been published in veterinary medicine.

The topic of body composition in sport requires a great deal of attention. Excessive adipose tissue acts as a dead weight, especially in situations characteristic for handball – jumps, when body weight must be repeatedly lift ed against gravity during locomotion and jumping. Th e purpose of the study was to determine body composition and distribution of liquids in individual body segments in a national team of female handball players (n = 16, age 24,0±3,5 years, body height 176,0±6,5 cm, body weight 72,5±8,3 kg). Body composition was measured by means of a multifrequency bioimpedance method InBody (Biospace). Th e examined parameters were the following: absolute and relative amount of fat free mass (FFM and  FFM/BW), percentage of fat mass (FM), absolute and relative amount of body cell mass (BCM and BCM/TH), total body water (TBW) distinguishing extracellular water (ECW) and intracellular water (ICW) and distribution of body liquids in individual segments. In the monitored group, we recorded the mean value of TBW = 42,58±3,99. Th e mean value of ICW was 28,92±2,53 l (67.92 %). Th e mean value of ECW was 13.66±1,57 l (32,08 %). FM made 20,16 ± 4,08 %. FFM for the whole sample was 57,82±5,27 kg; in relative values it was 0,80±0,04. Th e mean proportion of BCM in the monitored group was 40,47±3,55 kg, in relative values 0,56 ± 0.03. Monitoring distribution of liquids in the extremities showed a signifi cant diff erence only in the upper extremities (t15 = 5,95; p 0,01). In the lower extremities, we found out an equal proportion of liquids with an insignifi cant diff erence between the observed segments (t15 = 0,41; p > 0,05). Individual parameters of body composition indicate values corresponding to elite sport. Interindividual assessment revealed diff erences in terms of player’s function; however, when assessing parameters of body composition, it is not possible to express clearly the trend in dep endence on player’s function. Results of our study may help as a certain top standard for comparison of body composition in female players of a lower performance level with the aim of optimization and compensation of diff erences.

The tendency that has emerged in recent years towards an increase in the number of overweight children, as well as an increase in the incidence of children associated with obesity and overweight, actualizes the timely indication of deviations in the physical development of children in order to prevent health disorders. The article provides a comparative analysis of methods for assessing the physical development of children using somatometric indicators: methods of sigma deviations (deviation from standard arithmetic mean values by the value of sigma deviation), estimates on regression scales that take into account the correlation between body weight and body length and age (deviations from the proper values from M –1 to M + 2σR), body mass index estimates by calculating the Quetelet index, using the SDS-standard deviation score, Z-score (WHO 2007) and bioimpedance analysis. The generalized analysis in the age group 12–17 revealed the highest percentage of overweight children when analyzed using bioimpedansometry (20.9 %) and when assessing BMI according to the WHO method of 21.2 % regardless of gender and significantly lower indicators when assessing with using regression scales and sigma deviations (9.6 % among boys and 18.7 % — among girls when assessed using regression scales and 15.3 %, and 11.2 % — when assessed by the method of sigma deviations). The broad capabilities of bioimpedance analysis of body composition make it possible to diagnose the presence of overweight and obesity at the individual level. Comparable results obtained in bioimpedance analysis and in assessing body mass index using the method (WHO, 2007), allow us to consider this method in population studies of indication of overweight and obesity as a rather informative method.

Introduction. The aim of our study was to develop and use a population pharmacokinetic model for assessment of individual valproate clearance in children and young adults suffering from epilepsy. Material and methods. The analysis was performed using 52 steady-state concentrations of valproate collected from 26 epileptic patients during the routine clinical practice in our hospital. The mean values of age and total body weight were 19.92 years and 57.12 kg, respectively. NONMEM software with ADVAN 1 subroutine was used for model building and assessing the influence of different covariates. A validation set of 20 epileptic patients (one blood sample per a patient) was used to estimate predicted performances of the pharmacokinetic model. Results. The typical mean value of the clearance of valproate estimated by the base model in our population was 0.377 l/h. Out of five considered covariates (total body weight, age, total daily dose, gender and polytherapy) only the age of the patients was a significant determinant of the clearance of valproate. The final regression model for the clearance of valproate was as following: CL (l/h) = 0.223 + 0.00819

Background:Misbalance between energy intake and consumption is considered the main reason of obesity. However, over the recent years there has been a lot of emerging data concerning early origins of obesity that forms during intrauterine development and/or early age periods.Objective:Our aim was to study how physically developed are the children of early school ages.Methods:The study included children aged 7 to 10 years. Their physical development was assessed with the WHO AnthroPlus (2009) software.Results:652 children were examined. Of them, balanced development was found in: according to the WAZ index (body mass/age) — 466/530 (87,9%) schoolchildren; HAZ index (height/age) — 620/652 (95,1%); BAZ (body mass index/age) — only 438/652 (67,2%) children. Excessive body weight was found in 61 (18,8%) of the 324 girls and 65 (19,8%) of the 328 boys (р = 0,891), obesity — in 24 (7,4%) and 52 (15,9%) children correspondingly (р = 0,038).Conclusion:Having evaluated the physical development of early aged schoolchildren between the ages of 7 and 10 years, it is possible to state that there is evidence in favour of higher readings of mass-weight indexes as compared to the standard WHO population. Every third early age schoolchild can have physical development deviations, at the same time boys are obese twice as often as girls.

Background/Aim. Retinopathy of prematurity (ROP) is a multifactorial disease in premature infants. The aim of this study was to determine the incidence of ROP in children treated at the Center of Neonatology, Pediatric Clinic, Clinical Center in Kragujevac, Serbia. Methods. The study covered all children with birth weight below 2,000 g and/or gestational age below the 37th week, who from June 2006 to December 2009 underwent ophthalmological examination for ROP. The results of fundoscopy were classified in accordance with the International Classification of ROP. The treatment of infants and those with ROP was conducted in accordance with the early treatment of ROP study recommendations. We analyzed gestational age, birth weight and postconceptional age in two groups: healthy infants and those with severe form of ROP. Statistical analysis was performed using the SPSS 16. Results. A total of 478 children met the criteria of screening for ROP. Severe stage of ROP, which required laser treatment, had 102 (21.3%) children. Out of the infants with severe ROP 14 (13.7%) of the infants with APD had aggressive posterior disease, while two (0.4%) remained blind. The differences in the mean values of gestational age between the healthy and the children with severe form of the disease were statistically significant (p < 0.0005). The mean value of gestational age for the healthy children was 33.33 ? 2.28 weeks and for the seek infants 30.66 ? 2.79 weeks. The mean value of the weight in healthy children was 1.981 ? 407 g, and in sick children 1.535 ? 434 g which was statistically significant (p < 0.0005). Multivariate binary logistic regression showed that the occurrence of the disease depends on body weight and gestational age. Conclusion. The incidence of severe forms of ROP was 21.3%. Aggressive form of ROP was present in 13.7% of the children. The cut-off value for body weight was 1.740 g, and for gestational age 32.5 weeks.

Abstract: Background, nutritional status is a description of balance between the need of nutrientsfor keeping a good life, to maintenance normal body function also energy production in one sideand the consumption of nutrients in the other. Children in elementary school are the best target forimprovement of community nutrition because in the childhood the function of the brain organbegan to form so the development of intelligence is quite rapid. Lack of nutritional intake inchildren can inhibit the physical growth and thinking ability in children and subsequently reduce inlearning interest. Therefore the nutritional status of the children must detect immediately to carryout the preventive measurements. Objective, the purpose of this study is to know the nutritionalstatus of children at grade VI in elementary school Miftakhul Ulum Surabaya based on height andweight. Methods, this study is a quantitative descriptive using survey method, weighting indexinstrument by height in children aged 6–17 years old from Health Department in 2011. This studyused the measurement of body weight and height. Subjects of this study were all students at grade VIin elementary school Miftakhul Ulum Surabaya, which amount 81 children. Data collecting techniques use anthropometric measurements which include measurement of body weight and heightthen calculated base of data analysis techniques using quantitative descriptive with percentage.Result, study results showed most of the students were 12 years old (56.80%), mostly male (55.60%).most of them have body height 130–140 cm (37.00%), and body weight 31–40 kg (46,90%). Malechildren have more problems with their nutritional status (51.10%). Male children much oftenhave underweight and over weight (13.30%) than girls. By the increasing their age, their BMI willbe normal category (100%). By the age of 13 and 14 years old, the children will not have underweight (0%). Conclusion, based on the nutritional status of all children at grade VI, it can beconcluded that the nutritional status of children at grade VI in elementary school Miftakhul UlumSurabaya is in underweight category (very thin and lean) with percentage 56.80%. While the normal weight percentage 32.10%, and over weight (fat and obesity) with percentage 11.10%.

It is important to have a quantitative knowledge of the energy value of body-weight change (EV MJ/kg) when designing nutritional strategies for dairy and beef cows. Published values for EV vary widely. For example Chigaru and Topps (1981) give values for cows from 3.7 MJ/kg to 26.9 MJ/kg and Alderman, Broster, Strickland and Johnson (1982) give a mean value as high as 89.1 MJ/kg in mid-lactation. A wide range of values are also calculated for lactating ewes by Cowan, Robinson, Greenhaigh and McHattie (1979). The current ARC (1980) recommendation for cows is to use a constant value of 26.0 MJ/kg. Using mean values can be useful to make practical progress but we cannot avoid facing the fact that averaging, even on a selective basis, tends to obscure real and high variation in reported values. This paper will present a mathematical development which will define what is meant by the energy value of body-weight change and discuss some implications which follow. A final solution to the basic problem is not proposed.

The aim of this study was to investigate the influence of body composition on the anaerobic strength of the lower extremities, as well as the prediction of body composition on the results of anaerobic ability in professional football players. Materials and Method. The sample of respondents consists of female football players who compete in the highest rank of the competition, the Serbian Super League. The total number of respondents included in the study was 21 female football players (age 19.38 ± 3.69, body height 166.48 ± 6.17 cm, body weight 59.98 ± 7.09 kg). The study is of a transversal nature and testing was done in the pre-competition period. The sample of measuring instruments used in the research are body composition and assessment of anaerobic strength of the lower extremities. Assessment of body composition was performed indoors using a multifrequency bioelectric impedance (Inbody 770). Variables for estimating the anaerobic strength of the lower extremities were obtained using a bicycle ergometer (Monark 839E) in the Wingate Anaerobic Test. Results. The results of body composition show a statistically significant influence on the prediction of maximum anaerobic strength of the lower extremities in professional female football players (p < 0.05), as well as on the overall work in the anaerobic zone and the mean values ​​of anaerobic strength. Regression analysis of the influence of body composition on the parameters of maximum strength in (W/kg) and fatigue rate does not show statistically significant results. Conclusion. There is a statistically significant influence of body composition, such as: body weight, lean body mass (%), muscle mass in absolute and relative values, on the values ​​of maximum anaerobic strength, mean values ​​of anaerobic strength and overall work in professional female footballers.
