The aim in this study, will comparison anthropometric characteristics and motor performance tests to be between according to the ages of boys and girls ski athletes. A total of 41 Girls and 47 Boys ski athletes participated in this study voluntarily. One Wey ANOVA and LSD tests were used.In this study, there were differences in height and body weights statistical (p <0.001). 12 year old girl ski athletes were taller. Again, the body weight of girls is higher than men. In this study, the Sit and Reach Test values of girls and boys at 11 years of age were significantly higher than the values of boys and girls at 12 years of age (p <0.001). There was no difference between boys and girls (p> 0.05). The flamingo test values of boys and girls 11 and 12 aged changed according to gender and age statistical (p <0.01). The plate tapping test values of boys and girls 11 and 12 aged changed according to gender and age not statistical (p >0.05). It was statistically significant that girls' sit up and Standing Long Jump value was better than boys (p <0.001). It was statistically significant that boys' Bent Arm Hang test and mini cooper test was better than girls (p <0.001).Conclusion: Anthropometric characteristics and motor performance tests were found to be within normal limits according to the ages of boys and girls ski athletes. Physical characteristics and motor performance parameters can change according age and sex for 11 and 12 aged Child. For ski training and education's plans, according age and gender should be taken into consideration on child.

  Este estudio busca determinar los niveles de competencia motriz de estudiantes chilenos y las posibles diferencias en función del grado y del sexo. Participaron 377 estudiantes (37.7% niñas) de tercer y cuarto básico. La competencia motriz fue evaluada a través del test MOBAK 3-4. Se encontraron bajos niveles de competencia motriz. Los estudiantes de cuarto grado presentan un mejor desempeño motriz que los de tercero. Los niños presentan un mayor desempeño que las niñas en control de objetos, mientras que las niñas obtienen puntajes más altos que los niños en control del cuerpo, aunque con un tamaño del efecto irrelevante. Al contrastar estos resultados con los objetivos del currículum, muchos estudiantes no alcanzan los aprendizajes esperados, siendo necesario poner mayor énfasis en el fomento de la competencia motriz.  Abstract. This study aims to determine the levels of motor competence of Chilean students and possible differences according to grade and gender. 377 students (37.7% girls) of the third and fourth grade participated in the study. Motor competence was evaluated through the MOBAK 3-4 test. Low levels of motor competence were found. Fourth grade students showed a better motor performance than third grade students. Boys performed better than girls in object control, while girls scored higher than boys in self-movement, although with an irrelevant effect size. When these results are contrasted with the learning objectives stipulated in the curriculum, many students do not achieve the expected skills, what makes it necessary to place greater emphasis on the promotion of motor competence.

Introduction: Motor coordination is a result of interactions between many body systems, producing accurate and balanced kinetic actions. The evaluation of motor performance levels in children and teenagers may conserve and improve health and life qualities. Body composition may interfere considerably in motor coordination, particularly in overweight and obese conditions. Objective: To analyse the relationships between motor performance and body composition in children. Methods: Motor coordination was evaluated through the Körperkoordinations test für Kinder (KTK test), considering the motor quotient (MQ) and body composition using the body fat percentage (BF%) and body mass index (BMI). Results: BMI (38% and 36%) and BF% (28% and 22%), from boys and girls respectively, demonstrated that body composition is above the recommended. Girls presented MQ values lower than those observed in boys (p < 0.001). The groups with BFPs below the recommended value showed higher values of MQ than the normal group (p<0.05) and than children above the recommended ideal (p < 0.05). A reverse correlation was observed between MQ with BF% (r = -0.432) or BMI (r = -0.254). Conclusion: There are relationships between body composition and motor coordination in teenagers between 11 and 14 years old, related or not to gender and age.

Much research has been carried out on identifying gendered iconography on statue-menhirs. This paper seeks to develop this perspective by considering the broader body concepts. Body concepts are of interest to archaeologists because they are closely connected to issues of sex, gender, and age. By investigating stone sculptures, however, we are looking at an ideological view of the body that was produced by reducing the stone from its natural form into a statue-menhir. The presence of bodily features on the statue-menhirs suggests that it was important to construct a body, and that certain aspects of the body were chosen to be represented, either through the size and shape of the stone or iconography, while others were neglected. We propose this is a significant means by which stones were made into bodies and gendered beings. To investigate body concepts, we pose two questions: how was a statue-menhir body made, and how was it gendered? By following the reduction sequence of the stone as the technique of production, we investigate which bodily features were important in constructing a body and in gendering it. We do this through analysing and comparing three regional examples of anthropomorphic statue-menhirs: (1) The Lunigiana groups A and B in northwestern Tuscany and eastern-most Liguria, (2) the Atesino group in Trentino-Alto Adige, and (3) the Sion Type A in the Swiss Valais and the Aosta Style I in northern Italy. Although there is a shared statue-menhir tradition in the three regions and beyond, the observations in this paper suggest that the bodily gender categories were negotiated regionally.

AbstractBasic visual functions have evolved to allow for rapid detection of dynamic stimuli in our surrounding environment. In particular, looming stimuli are of relevance because they are expected to enter the individual’s interpersonal space representing a potential threat. Different studies showed that emotions can modulate the perception of visual looming stimuli and the borders of interpersonal space, defined as the area around the body that individuals maintain between themselves and others during social interactions. Here, we investigated how emotions modulate the perception and the physiological correlates of interpersonal space and whether such indexes change across age and gender. Children and adults were asked to quickly react to emotional looming stimuli while measuring their skin conductance response (SCR). We found that emotional looming stimuli shrink the borders of interpersonal space of males more than females, and that this pattern does not change with age. In addition, adults reacted faster to angry than happy and neutral faces, which is in line with the notion that threatening stimuli capture attention more quickly than other types of emotional stimuli. However, this was not observed in children, suggesting that experience with negative stimuli, rather than the evolutionary meaning they possess, may influence the boundaries of interpersonal space. Overall, our study suggests that interpersonal space is modulated by emotions, but this appears to be modulated by gender and age: while behavioural responses to emotional looming stimuli refine with age, physiological responses are adult-like as early as 5 years of age.

Purpose: To study the body weight and height of adolescents and to compare them with gender and age standards. All the children are from the Plovdiv region. Material and methods: About 185 children from three different ethnic groups have been studied. It also hase been developed and used specifically for this purpose an author's questionnaire for students, which contains open, closed, and mixed questions. Have been used descriptive statistics for quantitative (mean ± SD) and qualitative (percentage ± SEp) variables, also T-test for proving statistically significant differences between two independent samples. A p-value < 0.05 had been considered statistically significant for all tests. For the statistical processing, we have used the data analysis software IBM SPSS Statistics v. 25. Results: The study was conducted in the Plovdiv district in the period of May 2019 - July 2019. The subject of the study has been 185 adolescents from different ethnic groups. The logical units of the study were schools in Plovdiv and the village of Karadzhovo, which is part of the Plovdiv municipality. The gender distribution is 101 (56.6%) boys and 84 (45.4%) girls. The study covered mainly 96 Bulgarian children (51.89% ± 3.67), followed by 30 Turkish (16.22% ± 2.71) and 59 Roma origin (31.89% ± 3.43). The group of adolescents has been included students aged 11 – 15 years old. In the group of 11-year-olds, 61 (32.97%) Bulgarian children usually play sports out of school, followed by 29 (15.67%) Roma and 16 (8.65%) Turkish children. We have proved statistically significant differences between mean weight, measured in our sample compared to the population standard for the age of 11 years old boys (n=28, 45.84±13.42 kg vs n=134, 39.74±7.15 kg; t-test=2.34, p=0.026) and girls (n=35, 45.49±10.46 kg vs n=135, 41.60±9.03 kg; t-test=2.24, p=0.029), respectively. The height measured for both genders in this age group had not been statistically significantly different compared to the standard. No other differences between sample point estimates and population standard had been obtained by age groups and gender. Conclusion: For the age of 11-12 years old children, higher body weight had been found in the Bulgarian boys. The girls with the average highest values had been of Turkish origin.

Self-concepts (self-perceptions) of physical fitness and academic achievement were related to 14 field and laboratory indicators of physical fitness and to academic achievement for a large, national representative sample of Australian boys and girls aged 9 to 15 (N = 6,283). Correlations between self-concepts and the corresponding external criteria increased steadily with age in both the physical and academic domains. Consistent with predictions from frame-of-reference models, relations were stronger after controlling for gender and age, suggesting that self-concepts are formed relative to other students of a similar age and gender. Fitness self-concept was most strongly related to some individual measures (e.g., 1.6K run, 50M dash, push-ups, skin fold thickness, VO2max, long jump, and body girth scores) and some components of fitness (e.g., cardiovascular endurance, power, dynamic strength, and body composition) than others. Consistent with multidimensional perspectives of physical fitness, indicators from a variety of fitness domains contributed to fitness self-concepts.

Abstract The key objective of this research was to analyse and understand the different effect of gender and age on body image appearance at age 12 and 15 years in both gender groups. In other word age and gender how influence on adolescents body image appearance. The sample chosen for this study was 1429 (710 boys and 719 girls) from primary and secondary schools in Tehran. To verify the body image used of questionnaire Body Image Concern Inventory (BICI) (Littleton 2005). The difference between body image appearance of boy and girl, between at age of 12 and 15 years, was analysed and compared using the SPSS version20 ANOVA test. The ranking of the four group samples was achieved by using mean of body image appearance. On analysing the data, it was indicated that there was a significant effect of age, gender and interaction of the variables on body image on boys and girls at the age of 12 and 15 years. The result reveals that in the same age category, boys were at a better level of body image appearance than girls. Also, the result revealed that the body image appearance level was better in the younger age category.

Context Severe obesity affects the body favoring the development of serious diseases, including hypertension, diabetes mellitus, atherosclerosis and non alcoholic fatty liver disease. Bariatric procedures increased in Brazil in the last decade. Objectives The purpose of this study was to verify if gender and age in date of procedure resulted significant differences in metabolic syndrome parameters after surgery. Methods The study involved 205 medical records of adult patients undergoing Roux-en-Y gastric bypass, stratified by gender and age groups and followed one year by a multidisciplinary team. Results It was observed significant decrease in body mass index, fasting glucose and insulin at all ages and both genders. Lipid profile showed significant improvements except high density lipoprotein cholesterol. Ectopic fat in the liver has decreased after 6 months in patients classified with steatosis at baseline. Patients classified as hypertensive blood pressure levels decreased 6 months after surgical intervention. Conclusions Roux-en-Y gastric bypass proved to be an important tool in remission of metabolic syndrome parameters. The reduction of body mass accompanied to decrease in insulin resistance resulted in lower prevalence of comorbidities associated with obesity. The benefits were similar and extended both genders and all age groups between 18 and 65 years old.

Diabetes is a disease caused by high blood sugar in the body or beyond normal limits. Diabetics in Indonesia have experienced a significant increase, Basic Health Research states that diabetics in Indonesia were 6.9% to 8.5% increased from 2013 to 2018 with an estimated number of sufferers more than 16 million people. Therefore, it is necessary to have a technology that can detect diabetes with good performance, accurate level of analysis, so that diabetes can be treated early to reduce the number of sufferers, disabilities, and deaths. The different scale values for each attribute in Gula Karya Medika’s data can complicate the classification process, for this reason the researcher uses two data normalization methods, namely min-max normalization, z-score normalization, and a method without data normalization with Random Forest (RF) as a classification method. Random Forest (RF) as a classification method has been tested in several previous studies. Moreover, this method is able to produce good performance with high accuracy. Based on the research results, the best accuracy is model 1 (Min-max normalization-RF) of 95.45%, followed by model 2 (Z-score normalization-RF) of 95%, and model 3 (without data normalization-RF) of 92%. From these results, it can be concluded that model 1 (Min-max normalization-RF) is better than the other two data normalization models and is able to increase the performance of classification Random Forest by 95.45%.
