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.

Body Balance

Background: The aim of the study is to assess the body balance and podological parameters and body composition of young footballers in the context of the control of football training. Methods: The study examined the distribution of the pressure of the part of the foot on the ground, the arch of the foot, and the analysis of the body composition of the boys. The pressure center for both feet and the whole body was also examined. The study involved 90 youth footballers from Olsztyn and Barczewo in three age groups: 8–10 years, 11–13 years old, and 14–16 years. The study used the Inbody 270 body composition analyzer and the EPSR1, a mat that measures the pressure distribution of the feet on the ground. Results: The results showed statistically significant differences in almost every case for each area of the foot between the groups of the examined boys. The most significant differences were observed for the metatarsal area and the left heel. In the case of stabilization of the whole body, statistically significant differences were noted between all study groups. In the case of the body composition parameters, in the examined boys, a coherent direction of changes was noticed for most of them. The relationships and correlations between the examined parameters were also investigated. The significance level in the study was set at p < 0.05. Conclusions: Under the training rigor, a statistically significant increase in stability was observed with age. The total length of the longitudinal arch of both feet of the examined boys showed a tendency to flatten in direct proportion to the age of the examined boys. Mean values of the body composition parameters reflect changes with the ontogenetic development, basic somatic parameters (body height and weight) and training experience, and thus with the intensity and volume of training. This indicates a correct training process that does not interfere with the proper development of the body in terms of tissue and biochemical composition.

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.

Abstract Currently, autism spectrum disorders (ASD) are one of the main health care problems in both Poland and in other countries. There are limited studies on the physical growth and body composition among children and adolescents with ASD. Several studies have indicated that the prevalence of unhealthy weight is high among autistic patients. Therefore, the main aim of this study was to assess the prevalence of underweight, overweight and obesity of Polish boys with ASD and to analyse body composition. A cross-sectional study was performed on 29 Polish boys aged 3–11 with autism. Anthropometric measurements were taken. Bioelectrical impedance analysis (BIA) was used to evaluate body composition. The percentile values and z-scores for body height, body weight and BMI were calculated. The CDC cut–points were used to determine weight status. Statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) version 25. 16.1% autistic boys had z-scores for body weight above two standard deviations, 12.9% had z-scores for body height above two standard deviations and z-scores for BMI above two standard deviations were found in 19.4% of the boys. 13.8% of autistic boys were underweight, 48.3% had healthy weight, 20.7% were overweight, and 17.2% were obese. The mean value of body fat percentage was 18.46%, and 16.1% of the boys with ASD had higher than normal fat tissue. There is a high prevalence of overweight and obesity among Polish boys with autism.

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.

AbstractSignificant factors affecting body composition and consequently professional and amateur bodybuilders’ performance are both training loads and diet.The aim was to assess dissimilarities in anthropometrical traits and body composition between males practicing bodybuilding professionally and as amateurs, considering their diet and training.The study comprised 55 athletes, i.e. 29 professionals attending national championships and 26 amateur bodybuilders. All participants underwent anthropometric measurements involving body height, waist, arm and thigh circumferences and skinfolds covering trunk and extremities. The original nutritional behavior questionnaire and a 24-hour survey were used. An electronic scale was used to measure body weight and body composition was analyzed with the BIA method. In statistical analysis, the Shapiro-Wilk (W-test), t-student and Mann-Whitney U test were applied.An adipose tissue, assessed on the basis of skinfolds was significantly lower in professionals (p<0.05), whereas lower mean values of body fat free mass (FFM) were found in amateur bodybuilders (p<0.01). Diet survey presented differentiation both in the amount of consumed protein in the diet (1.98 g/kg), in its percentage participation in the diet (21.2%) in favor of the professionals (p<0.05). Significant differentiation was between the groups in the amount of consumed fats (p<0.05). In case of resistance trainings time, energy expenditure and number of trainings were higher for professionals (p<0.05).Bodybuilders feature better developed muscle mass of extremities and a smaller share of percentage of fat mass in body composition in comparison to amateurs. Professional bodybuilders consume proper amount of carbohydrates and fats and significantly higher level of protein, fiber and energy in diet compared to amateur group. In contrary, higher intake of fats is typical for amateur bodybuilders.

The aim of our observation was to measure selected anthropometric characteristics and to analyze actual body composition in children of younger school age from elementary schools in Prague. The group consisted of a total of 222 probands, boys (n-117) and girls (n-105) aged 8–11 years (average boys age = 9.0 ± 1.0 years, body height = 139.9 ± 8.6 cm, body weight = 32 ± 7.5 kg, BMI = 16.3 ± 2.4 kg.m–2). Average age girls = 8.9 ± 0.9 years, body height = 137.3 ± 8.8 cm, body weight = 30.5 ± 7.3 kg, BMI = 15.9 ± 2.4 kg.m–2). The BIA 2000 M multi-frequency apparatus (whole-body bioimpedance analysis) was used to analyze the body composition. Children of younger school age showed higher TBW values – total body water (boys 65.5 ± 6.0%, girls 66.6 ± 6.5%), low body fat (boys 16.1 ± 2.4%, girls 16.5 ± 2.9%) and higher ECM/BCM coefficients (boys 1.0 ± 0.13, girls 1.02 ± 0.11). The authors draws, attention to the importance of monitoring other body composition parameters. The percentage of fat-free mass (FFM) and the share of segmental distribution of body fat and muscle mass on individual parts of the human body.

Objective: A polymorphism near the promoter region of the IGF-I gene has been associated with serum IGF-I levels, body height and birth weight. In this study, we investigated whether this polymorphism is associated with body composition in young healthy subjects in two cohorts of different generations. Design: Observational study with repeated measurements. Methods: The study group consisted of two comparable young Dutch cohorts with a generational difference of around 20 years. The older cohort consisted of 359 subjects born between 1961 and 1965. Measurements were performed from 13 until 36 years of age. The younger cohort consisted of 258 subjects born between 1981 and 1989. Measurements were performed from 8 until 14 years of age. Height, body mass index (BMI), fat mass, fat-free mass, waist and hip circumference were compared between wild-type carriers and variant type carriers of the IGF-I polymorphism. Results: In the younger cohort, body weight, BMI, fat mass and waist circumference were significantly higher in female variant carriers of the IGF-I polymorphism. A similar trend was observed in male variant carriers. In contrast, these differences were not observed in the older cohort. Irrespective of genotype, the younger cohort showed a significantly higher total fat mass, body weight and BMI compared with the older cohort. Conclusions: Because the differences between both genotypes were small, it seems likely that the genetic variability due to this IGF-I polymorphism impacts only slightly on body composition. Importantly, our study suggested that associations between this IGF-I promoter polymorphism and body composition possibly reflect a gene–environmental interaction of this polymorphism and that an environment that promotes obesity leads to a slightly more pronounced fat accumulation in variant carriers of this IGF-I polymorphism.

This study was carried out in order to identify the different parasites (ecto and mesoparasites) infesting the tortoise Testudo graeca graeca. For this, a population of 24 tortoises was studied from mid-March to May 2018, in the region of Aflou-Laghouat, within two sites: Djellel and Oued Sebgag. The turtles were captured at the time of their activity; sex, age, body weight, total length of the shell and body height were determined. A careful search for parasites has been carried out using various recommended techniques. A total of 126 Hyalomma aegyptium ticks were identified, with an overall prevalence of 71%, an average intensity of 7.4 and an abundance of 5 ticks per individual. The stool examination identified six mesoparasites, namely: Angusticaecum holopterum, Enterobius vermicularis, Strongylus sp, Nematodirus sp, Trichostrongylus sp, Fasciola hepatica. The sex of the host showed a significant influence on the parasitic infestation: the females were four times more infested than the males.

Introduction. Body composition measurements and dynamometric parameters are very reliable indicators of performance and progress in the training process. The aim of this study was to assess the body composition and muscle strength and to establish the correlation between these parameters in various sports. Material and Methods. The study was conducted at the Department of Physiology, Laboratory of Functional Diagnostics, Faculty of Medicine in Novi Sad. It included 45 male examiners: 15 handball players, 15 football players, and 15 sprinters. The following parameters were measured: body weight, body height, body mass index, skinfold thickness, and dynamometric parameters of calf extensors and forearm flexors. Results. In comparison to football players and sprinters, handball players presented with statistically significantly higher body mass index (p < 0.05). In terms of skinfold thickness, there were statistically significant differences (p < 0.05) between the groups. The values of dynamometric parameters of calf extensors (average value of load of the calf extensors, maximum value of load of the calf extensors, strength of muscle contraction of calf extensors) showed no statistically significant differences between the groups of athletes (p > 0.05). Compared to football and handball players, sprinters had significantly higher values of dynamometric parameters of forearm flexors (average value of load of forearm flexors, maximum value of load of forearm flexors, strength of muscle contraction of forearm flexors). Conclusion. In the group of handball players there was a positive correlation between the percentage of the body fat and muscle power in both examined muscle groups; however, among the football players and sprinters, a correlation was found between the body composition and strength of calf extensors.

The aim was to establish differences in morphological characteristics of 48 selected female younger cadet (U14) handball players (age 13.88±0.46 years) in the playing positions of wings, backs and pivots. The sample of variables embraced 24 morphological measures defining the already established four latent body dimensions. Univariate ANOVA revealed the significant global differences among the three groups of U14 players in 11 morphological measures. Between the backs and pivots no significant differences were established. The greatest differences between the pivots and wings were established in body height, leg length, arm length, ankle breadth, body weight and calf circumference (p&lt;.01). The greatest differences between the wings and backs were established in four variables: body height, arm length, knee breadth and ankle breadth (p&lt;.01). We endorse the interpretation that specificities of technical-tactical activities executed by backs and pivots in attack repose in the background of the established differences, that is, backs and pivots are exposed to more body contacts in attack in which they must overcome defenders’ resistance. In the sample of the Croatian U14 female handballers apparently no somatotypic component prevailed. However, a slightly larger contribution of endomorph component was perceived in the pivots’ body composition, which was in line with the general results of the entire age group. In U14 backs both the endomorph and mesomorph component were pronounced equally, whereas all the three components were of even values in the wings
