Opis:
University education is a period of human life when lifestyles or person’s activity are critical to the development of somatic build, while identification of the somatotype allows for corrections or recommendation of effective physical activity programmes. The main aim of this study was to assess selected features of body build and to identify somatotypes of young people at early stages of education at Jozef Pilsudski University of Physical Education in Warsaw depending on the field of study. The study examined 394 students of physical education (PE) and sport (S). Anthropometric measurements were the main research method used in the study. Physical body build (somatotype) was identified using the Heath-Carter method. The ANOVA/MANOVA analysis of variance was employed to determine the significance of differences in values of anthropometric and somatic characteristics between the groups of students. Students of physical education were characterized by a somatotype with a code of 3.08-4.6-2.62 (endomorphic mesomorph). In students of sport, the somatotype code was 3.0-4.58-2.37 (endomorphic mesomorph). Compared to S students, significantly (p < 0.05) higher values (by 10.5%) of the ectomorphy component were found in PE students. The results revealed the need for more research into the somatic build of students of physical education, taking into account the changes in their living conditions (including socio-economic environment), since graduates are expected to promote physical activity in the future. It is also necessary to carry out identical research at the end of studies in order to evaluate the effect of university curricula on the somatic build of students.

Introduction. Environmental conditions have been changing over the years and the body’s capacity to adapt affects human development, its growth and typogenesis. Aim. To confirm the secular trend in the population of children and adolescents aged 4 to 18 from Rzeszów in the last 35 years in terms of growing and differentiation body proportions. Materials and methods. In 2013/2014, a total of 1,563 children from Rzeszów were examined. The length of the trunk, the upper limb, the lower limb, the width of the shoulders and the width of the hips were measured and the following indices were calculated: trunk length, upper limb length, lower limb length, inter-limb, hip-shoulder and shoulder width. The data was subjected to statistical analysis and compared to the data collected in 1978/79, 1993/1994 and 2003/2004. Results. During the 35-year period, the following symptoms were observed: elongation of upper and lower limbs in both sexes, increase in shoulder width in boys from 15-18 years of age, and in girls generally in the entire examined age, tendency to decrease in hip width in both sexes in most age classes. Conclusions. The secular trend in the population of children and adolescents aged 4 to 18 from Rzeszów in the last 35 years regarding growth process and differentiating body proportions was confirmed.

Objectives: The aims of the present study were to identify the anthropometric variables in elite roller hockey players in the 21st century and to compare the results with other indoor sports with similar somatotype. Methods: A descriptive study was performed in 41 elite roller hockey male players (mean age 25.63 ± 4.76 years, age range 19-34 years), including anthropometric measures, body composition and somatotype. A bibliographic review about roller hockey anthropometry was performed, including also other similar sports (field hockey and ice hockey). The results of the articles found were compared with the results obtained in our study. Also, a comparison between goalkeepers (n=8) and field players (n=33) results was performed. Results: The anthropometric results in this study showed higher values in height, weight and body mass index in comparison with previous articles about roller hockey anthropometry, showing similarities with the values of ice hockey players. In our sample, goalkeepers showed higher values of weight, body fat percentage and body mass index than field players. Conclusions: We concluded that 21st century elite roller hockey players are taller and heavier than those players studied in previous articles.

The purpose of the present study was: 1) to determine young tennis players’ fitness and anthropometric characteristics; and 2) to determine to what extent these characteristics relate to the players’ national ranking. Forty young (age 15.1 ±0.4) trained male tennis players, who were ranked from 1 to 40 in their age group in the country’s youth tennis players list, were tested for speed, speed endurance, flexibility, strength, specific agility and quickness, aerobic capacity, height, and weight. Significant correlations were found between the players’ ranking and speed (r = 0.430 – 0.475), specific agility and quickness (r = 0.626), speed endurance (r = 0.562), strength (r = –0.416), aerobic capacity (r = –0.581), flexibility (r = 0.352), height (r = –0.443), and weight (r = –0.293). Stepwise regression analysis indicated that specific agility and quickness accounted for almost 40% of the players’ ranking, while its combination with the players’ height accounted for 56%. The results imply the overall importance of anaerobic capabilities and tennis-specific movements to the young tennis players’ ranking. The results also emphasize the importance of tennis-specific tests to the young tennis players’ performance evaluation

Anthropometric indicators and motor abilities are significant components of the successful implementation of the physical potential of young basketball players. The aim of the study was to describe and compare anthropometric characteristics, indicators of physical and special preparedness for basketball players under the age of 12 and up to 14 years, to identify the presence and degree of relationship between these indicators in each group of athletes. Athletes (n = 50) were grouped in groups under 12 years (U12, 10.97 ±0.48 years; n = 24), and under 14 (U14; 12.96 ±0.49 years; n = 26), body height and body weight were measured, dexterity and indicators of special preparedness were tested and compared (“Throws into the basket from different positions”, “Free Throws”, “Ten eights”). U12 players showed lower performance than the U14 group in all tests except the “Free Throws” test. All athletes showed astrong correlation between jumping and dexterity (p < 0.01). The U14 athletes showed astrong (p < 0.01) and moderate (p < 0.05) relationship between the indicators of special preparedness. Assessment of indicators of physical development, physical and special preparedness of athletes, the study of the relationship of these indicators at different periods of ontogenesis will help rationally differentiate training loads, emphasize pedagogical influences and optimize the training process.

Objectives: This study aimed to examine the reliability of functional balance tests in 7-10 year-old children, as well as the relation between the functional balance tests and anthropometric parameters.   Methods: The study sample was composed of 80 7-10 year-old children (40 boys and 40 girls) from Nishapur (Iran). The participants were selected randomly with the approval of the Nishapur Education Department. Romberg's test and Sharpened Romberg Test were used to assess static balance. Y Balance Test was used to assess semi-dynamic balance. Timed Up and Go Test and Tandem Gait Test were used to assess dynamic balance. The following anthropometric parameters were measured: weight (kg), height (cm), leg length (cm), arch of the foot (cm), upper body length (cm), lower body length (cm), upper limb length (cm). The statistical analysis was performed with SPSS 20. Findings: Romberg test was not reliable. Sharpened Romberg Test was reliable in girls. Timed Up and Go Test and Tandem Gait Test were reliable in boys. Y Balance Test was reliable in boys and girls. The analysis of the correlation between functional balance tests (static and dynamic) and anthropometric parameters according to sex showed that there was only a significant negative correlation between arch of the foot and Sharpened Romberg Test in girls (r=-.43; p=.00). Conclusions: Sharpened Romberg Test is reliable in Iranian 7-10 year-old girls. Timed Up and Go Test and Tandem Gait Test are reliable in Iranian 7-10 year-old boys. Y Balance Test is reliable in 7-10 year-old Iranian children. Static balance has a significant and negative correlation with the arch of the foot in Iranian 7-10 year-old girls.

Purpose:To demonstrate the relationship between variety of food intake described with Food Intake Variety Index and nutritional status of Polish adolescents aged 13-15 years.Materials and methods: Pattern of food consumption for 131 adolescents (52% boys, 48% girls, mean age 14.4 ± 0.9) was evaluated by using FIVeQ (Food Intake Variety Questionnaire), whose interpretation allowed to determine FIVeI (Food Intake Variety Index). According to FIVeI four levels of variety of food consumption were defined: inadequate, sufficient, good and very good. Nutritional status was examined with selected anthropometric parameters, i.e.: weight, height, thickness of the skinfolds, body circuits, BMI (Body Mass Index), AMC (Arm Muscle Circumference), WHtR (Waist-to-Height Ratio), WHR (Waist-Hip Ratio) indexes and FM (Fat Mass), %FM (Fat Mass Percentage), FFM (Fat-free Mass), taken with the FUTREX device. In addition, measurements of BP (Blood pressure) were used for assessing nutritional status.Results:Variety of food intake for majority of examined adolescents was defined as sufficient (FIVeI = 28.4 products/week). The average BMI value for both sexes was 20.4 kg/m2, and fat mass percentage was 22.4%. Analysis of percentile ranges of given anthropometric parameters and BP according to gender and level of FIVeI showed that generally their values were within the normal range (10-90 percentile), although overweight and obesity was found in 11% of the adolescents. 38% of the examined group had values of blood pressure indicating prehypertension.Conclusions:Overall nutritional status was defined as good, however variety of food consumption was inadequate and needs improvement. Alarming blood pressure values require further investigation.

Introduction: Because of the fact that detailed data on the physiological characteristics of Pencak Silat are still limited. The primary purpose of this study to assess the physiological responses of Pencak Silat athletes and a secondary aim is to compare the physiological responses of Pencak Silat athletes with physiological responses of Taekwondo athletes. Material and Methods: This study has included 17 male junior martial art athletes (aged 15-16 years). This study requires all participants to completed one familiarization session and two experimental sessions. During the first session (laboratory condition), anthropometry was measured in the laboratory, and during the second session (on-court condition), the participants completed tests for anaerobic capacity (sprint test 60-m, vertical jump, push-ups, and sit-ups) and VO2max test. Results: The statistical analysis revealed no significant differences in anthropometry, vertical-jump, sit-ups, push-ups, and 60-m sprint results among TKD and PKS groups. Furthermore, the TKD group had significantly higher VO2max (p=0.015), when compared with the PKS group. Conclusion: The present investigation describes similar physiological characterizes, such as weight, height, BMI, BMR, body fat and also performances of vertical jump, situps, push-ups, and 60-m sprint tests among Taekwondo and Pencak Silat athletes. However, in comparison with junior Pencak Silat athletes, the junior Taekwondo athletes have better VO2max.

Background. Bakery products such as bread, rolls, croissants and others are an important part of eating habits. Recently, their consumption has been associated with an undesirable increase and prevalence of overweight or obesity. Objective. The aim of the work was to analyze the influence of the consumption frequency of selected types of bread / bakery products on anthropometric parameters in a group of university students. Material and Methods. The group was composed of 120 volunteers consuming different types of bread / bakery products with different consumption frequencies during the week. The anthropometric parameters were measured by InBody 720. To obtain information on the frequency of consumption we used the questionnaire method. Results. The results suggest that in most cases it is not the type of product that is decisive, but its quantity consumed and frequency of consumption supported by low daily physical activity, resp. sedentary lifestyle. We found similar results of the influence of the consumption frequency on anthropometric parameters for all types of bread. Low levels of physical activity, basal metabolism and consumption of selected types of bakery products (wheat bread, wheat rolls, sweet pastries and gluten-free variants) can cause an increase in visceral as well as total body fat, weight gain, BMI, at the expense of fat-free mass. Our results showed that the groups of participants who did not consume a certain type of bread at all, rarely or 1 to 3 times a week, showed higher values of the examined parameters (BMI, body weight, body fat percentage, WHR) compared to the group which consumed a particular type of bakery products on average 4 to 7 times a week. The parameter ́s values were largely influenced by the levels of physical activity. Conclusions. Based on the results it is possible to assume that if the bakery products are the part of a balanced diet with regard to the individual energy needs, it should not be the main cause of overweight / obesity in humans

This paper presents an anthropometric database of high school and university students from Kuala Lumpur,Malaysia. Forty-one high school participants (21 males and 20 females), 13–17 years old, and 143 university students (74 males and 69 females) took part in the study. Twenty-one static body dimensions were measured. The greatest mean differences in the anthropometric data between male and female high school students were found in the sitting elbow height. In addition, a comparison of anthropometric data of male and female university students showed that data for males and females were significantly different, except for buttock–popliteal length, sitting elbow height and thigh clearance. The primary aim of this study was to develop an anthropometric database that could be used as a primary reference in designing products, devices and equipment for ergonomic learning environments.

Using data collected during the inter-war period, the article seeks to identify long-term biological effects of food shortages and the increased incidence of contagious diseases during the First World War on a population of pupils of Cracow schools. This goal is achieved through an analysis of the remaining source materials from 1919–33 concerning the height of the population in question. The study found that the impact of the war manifests itself in a lower average height of pupils born in 1915 and in delayed puberty among the cohorts of 1912–15. The article also lists the potential consequences of such drastic long-term effects of the war.

Impact of Seat and Back Angle Settings on Seating Furniture Quality: An Experimental Study. The fundamental measure of the quality of seating furniture is seating comfort. Sitting comfort is described in the literature by the discomfort coefficient D, calculated from the pressure values and distribution measured between the human body and a sitting furniture "body support system". The work aims to experimentally verify the influence of selected anthropometric features on sitting comfort. The research was carried out on 12 people using a piezoelectric sensor mat and a model of adjustable sitting furniture. The study investigated how different seat and backrest inclination variants impact pressure distribution. The test results are the values of the contact pressures and discomfort coefficients D for nine combinations of the backrest and seat inclination related to the anthropometric characteristics of the tested group of people. The results indicate that anthropometric factors, such as body mass index (BMI) and user gender, significantly impact objective seating comfort. These findings will help optimize the seating furniture dimensions at their design stage.
Wpływ ustawienia kąta siedziska i oparcia na jakość mebli do siedzenia: badania eksperymentalne. Podstawową miarą jakości mebli do siedzenia jest komfort siedzenia. Komfort siedzenia określany jest w literaturze przez współczynnik dyskomfortu D, obliczany na podstawie wartości i rozkładu nacisków zmierzonych pomiędzy ciałem człowieka a „układem podparcia ciała” mebli do siedzenia. Celem badań była eksperymentalna weryfikacja wpływu wybranych cech antropometrycznych na komfort siedzenia. Badania przeprowadzono na 12 osobach z wykorzystaniem piezoelektrycznej maty sensorycznej oraz modelu regulowanego mebla do siedzenia. Zbadano, jak różne warianty pochylenia siedziska i oparcia wpływają na rozkład nacisków. Wynikiem badań są rozkłady nacisków oraz wartości współczynnika dyskomfortu D dla dziewięciu kombinacji nachylenia oparcia i siedziska odniesione do cech antropometrycznych badanej grupy osób. Analiza wyników wskazuje, że czynniki antropometryczne, takie jak wskaźnik masy ciała (BMI) i płeć użytkownika, znacząco wpływają na obiektywny komfort siedzenia. Spostrzeżenia te pomogą lepiej zoptymalizować wymiary mebli wypoczynkowych na etapie ich projektowania.

Opis:
Steady decline in habitual physical activity in children and youth has resulted in an increase in body weight with age and a decline in functional ability. Hypokinesia in conjunction with poor diet and stress levels are prerequisites of lifestyle diseases such as cancer, cardiovascular and metabolic diseases and obesity. In this partial research, being part of the VEGA research No. 1/1343/12 "Selected risk factors of obesity and exercise prevention", we looked at the incidence of health problems related to BMI and physical activity in college students. We calculated BMI based on anthropometric measurements of body height and weight. Using the questionnaire method, we collected data concerning subjectively assessed incidence of health problems and overall representation of physical activity (PA) in the lifestyle of respondents. The study group comprised 1,963 students, including 1,169 female and 794 male undergraduates from two Slovak universities. Health problems with the largest incidence were back pain, alergy, low blood pressure, headache, palpitation and respiratory diseases. Our research confirms that a greater representation of PA in students' lives positively relates to a lower BMI. The results of logistic regression confirm a significant relation between BMI and the following health problems: back pain, palpitation, high blood pressure, obesity, low blood pressure and respiratory illnesses. PA significantly corresponds with the occurence of health problems related to upper respiratory tract and high blood pressure.
