This study aims to find relationships between nutritional status, leptin and puberty. Methods. The research covered 66 healthy girls aged 9.8 ± 0.6 years, in prepubertal period. Body height, weight, arm circumference and skinfolds were measured, and serum leptin concentration was estimated. The evaluation of the pubertal stage and anthropometrical measurements was carried out again in a year's period. Results. During the observation, 32 girls reached the time of puberty (group I), while the other 34, at the same age, were still at prepubertal stage (group II). The girls in group II were shorter, lighter, had lower arm circumference, thinner skin fold on abdomen (p<0.02) and lower serum leptin concentration (p<0.003). Highly positive correlations between BMI, skin folds thickness and leptin concentration were proved. Conclusion. The results indicate relationships between the fat tissue amount, blood leptin concentration and puberty in girls.
Dokonano przeglądu piśmiennictwa z zakresu somatometrii stosowanej do pomiaru stanu odżywienia. Omówiono pomiary wysokości i masy ciała, grubości fałdów skórno-tłuszczowych, obwodów ramienia, talii i bioder, szczególnie osób starszych i niepełnosprawnych. Przedstawiono sposoby wyliczania najczęściej stosowanych wskaźników antropometrycznych oraz ich interpretację.
For many years, students of various backgrounds have been subject to research, including the anthropological studies. The second half of the 20 th century under - went a change in the anthropological view on the somatic race selection of pupils from various types of schools and faculties. The major aim of this work is to present the typological diversity of female students in the science faculties at the University of Rzeszów in the face of Kretschmer. There were the following specific aims: research in the influence of the social environment on the somatic structure of the female students, specification of the influence of the body structure and the social environment on the menarche of the surveyed students and the comparison of the results to the results of the authors in other academic centers in Poland. 2009/2010, 143 randomly chosen students of the Biological and Agricultural Studies at the University of Rzeszów were researched. Only full time course students were subject to the research. The standing position concerned the following measurements: body height (B-y), shoulders girth n(a-a), coxal girth (ic-ic), chest girth (at xi) and bodyweight. For each of the feature, the following parameters were taken: arithmetic mean ( X) standard deviation (Sd), variance (Sx), variation coefficient (V), minimum and maximum values. Based on those values, the body features of the students of various social origins and university specializations were compared. The evaluation of the statistical significance of the differences in the results of the students and the age of menarche of the students from cities compared to villages was conducted using t-Student test (p < 0,05).The somatometrical results showed the following indicators: Rohrer indicator, growth and shoulder indicator, chest girth indicator, BMI indicator aso-called “Kretschmer’s indicator”. On the basis of the above-mentioned indicators (excluding the BMI indicator), according to Kretschmer’s typology, the following female students’ body structures were specified. The survey data provided social and environmental birth order and the age of students’ menarche (the retrospective method): 1) The vast majority of the students of thee science faculties of the University of Rzeszów have the leptosomic body structure; 2) Students living in the village usually have wider shoulders and wider chest girths than the students living cities. Students living in villages are also heavier; 3) Sthenic-built women mature earlier, while women who have leptosomic body structure mature later; 4) Women students of the University of Rzeszów do not differ from other female students in Poland; 5) No relation between the place of living and the age of menarche was observed; 6) The students of the University of Rzeszów surveyed in 2009/2010 had heavier body structures than the students of 1999/2000.
Vertical jump test (VJT) is one of the important determinants of physical fitness. VJT score in school going children of West Bengal, India has been reported. However, pertinent data in young sedentary Indian males and females are unavailable. Moreover, the relationship of VJT with anthropometric parameters and different components of body composition has not yet been explored in Indian context. Debatable findings have been reported regarding the impact of body composition on VJT score. The present study was aimed to evaluate the VJT score in young sedentary Indian university students and its relationship with anthropometric parameters and different components of body composition with special reference to gender variation. Healthy sedentary university students (males n = 40 and females n = 40) with similar socio-economic background and age group of 21–25 years were randomly sampled for the study from the post-graduate section of the University of Calcutta, Kolkata, India. VJT was evaluated by Sargent Jump Test, and body composition was determined by skinfold measurements. Body height, body mass, %Fat, Total Fat (TF ), LBM and VJT score depicted significant (p < 0.001) difference between male and female groups. The VJT scores obtained in the male and female groups were in the range of below average and poor, respectively. Physical parameters did not influence the VJT score in both genders. In the present study the VJT score exhibited significant (p < 0.001) negative correlation with %fat, individual skinfold, sum of skinfolds, and TF. Hence, body fat content posed as a hindrance to achieve higher jumping height, especially in females, where the lean mass helped to achieve greater VJT score in males.
This study analyses, using selected somatometric features, secular trend changes which have occurred over a quarter of a century in female and male students of the Medical University of Łódź. The study is based on the results of an anthropometric survey carried out among first-year students who commenced their studies in the academic years 1978/79 (240 females and 193 males), 1982/83 (347 females and 188 males), 1988/89 (178 females and 165 males) and 2003/04 (188 females and 77 males). The following features were examined in all participants in the survey: body height (B-v), the height of the lower body segment measured from a floor base to the crista iliaca at the point on the mid-axillary line (B-ic), shoulder width (a-a), intertrochanteric distance (tro-tro) and resting chest circumference. To compare average values Student’s t-test was used with assumptions of equal and unequal variances. To gauge the magnitude of changes in specific features in the course of a quarter of a century a percentage difference in results was calculated for the years 2003/2004 and 1978/1979. The basis for the calculations was the initial value of a feature at the beginning of the period analysed. It was determined that in the 25-year period analysed (1978–2003) the young people commencing studies at the Medical University of Łódź exhibited an acceleration in the height of the lower body segment (B-ic) and of the intertrochanteric distance (tro-tro) and a deceleration in resting chest circumference. Additionally, an increase in shoulder width has been noted in female students; no significant intergenerational changes were noted in body height, although the last 15 years display certain symptoms of deceleration; there is an emerging tendency towards a blurring of the differences in body proportions between the sexes in the environment of the young people studying at the Medical University of Łódź.
