Body shape in relation to socio-economic status in young adults from the basque Country

Body shape has a great variability determined, partly, by energy intake and physical activity, as well as by gender and age. The aim of this research was to analyse the relation between socio-economic status (SES) and body shape estimated through the somatotype, in a sample of university students. The sample included 316 males and 635 females aged 18-33. Somatotype was estimated by the Heath-Carter anthropometric technique. The information included data of SES. A MANOVA test was used to test differences among groups. The mean somatotypes were 4.0-4.4-2.3 in males and 5.4 -3.4-2.2 in females. Sexual dimorphism for the whole somatotype was found (p < 0.001). There is a greater stability of the body shape in females regarding SES and more variability in males. Males' somatotype was significantly related to SES, low socioeconomic levels were associated with high values of endomorphy and mesomorphy.     

A three-year study of the effects of exercise on active young men.

The changes occurring in leanness-fatness, physical working capacity, isometric strength, and motor ability have been followed in 20 highly active young adult males over a period of 3 years. Body weight and estimated percentage of fat increased over the 3-year period but there were no significant changes in the other variables. Within the 3-year period physical working capacity and relative leanness-fatness showed significant variations which are attributed to the state of training of the subjects. Strength was found to be highly related to somatotype but was apparently not influenced by the state of training; changes in relative leanness-fatness occurring with training were found to be influenced by somatotype.

Gender differences in anaerobic power tests

The purpose of this study was to determine if the differences in anaerobic power between males and females could be accounted for by differences in body composition, strength, and neuromuscular function. A total of 82 untrained men and 99 women took part in the study. Body composition, somatotype, isometric strength, neuromuscular function were measured, and four anaerobic power tests performed. The men were significantly different from the women on all strength, power, and neuromuscular measurements except reaction time and on all anthropometric and somatotype dimensions except ectomorphy. Strength and anthropometric dimensions were similarly related to anaerobic power values within each sex. Relative fat (%fat) exerted different degrees of influence on sprint and jump performances in each sex. Removing the influence of anthropometric, strength, and neuromuscular differences by analysis of covariance reduced, but did not remove, the significant differences between the sexes. Therefore, factors other than lean body mass, leg strength, and neuromuscular function may be operating in short-term, explosive power performances to account for the differences between the sexes. The task-specific nature of anaerobic power tests and the relatively large influence of anthropometric factors on power production were confirmed.     

Study of somatotype in Italian children aged 6 to 10 years

The aim of the present research was to study the variations of somatotype, calculated by the Heath-Carter anthropometric technique, during growth in a sample of children (416 males and 402 females), aged 6 and 10 years, attending primary and secondary schools of L'Aquila and its province (Abruzzo, Italy). The sample was subdivided into “urban” and “non-urban” groups, on the basis of the residence of the children, to examine possible differences in growth related to the different environments. This study give an account of the somatotype components between urban and non urban childreen between the age 6 and 10 years. A tendency toward an increase of endomorphy (adipose component) with age was noticed in both sexes. In females, ectomorphy (component of physical linearity) tended to increase and mesomorphy (muscular-skeletal component) showed a slight decrease during growth, while males exhibited a discontinuous trend. The differences between urban and non-urban children were not significant, although generally higher values of endomorphy and mesomorphy were found in males and females of the urban sample. The differences between the sexes consisted of higher values of endomorphy and lower values of mesomorphy in females. Ectomorphy was similar in the two sexes.

福建畲族人群体型特征

史料记载早在唐代以前畲族就居住在粤、闽、赣三省的交界处,现今畲族主要分布在福建、浙江、江西、广东、安徽、湖南、贵州等7个省份,但关于畲族的起源与迁移在学界一直存在较大争议。本研究在福建省福安市和福鼎市随机选取畲族年满18周岁的成人504人(其中男289人,女215人) 测量身高、体质量、肱骨内外上髁间径、股骨内外上髁间径、上臂紧张围、小腿围、肱三头肌皮褶、肩胛下皮褶、髂前上棘皮褶及小腿内侧皮褶等10 项体质指标,利用Heath-Carter 体型法分析福建东部畲族人群的体型,畲族男性平均体型（5.02-3.76-1.76）为偏中胚层的内胚层型,女性平均体型（6.91-3.50-1.23）为偏中胚层的内胚层型。将福建畲族三个因子值与其他少数民族及汉族进行比较,结果显示畲族体型与汉族群体更为接近,其中与闽南语族群汉族、闽东语族群汉族和广西汉族最为相近,与南方少数民族族群反而差异更大,提示在畲族的形成过程与汉族有着很大联系。本研究为畲族族源研究提供生物学方面的参考依据,也为我国人类学研究补充必要的数据和资料。

Factors affecting the work productivity of Oraon agricultural laborers of Jalpaiguri district, West Bengal

In developing countries like India, where the incidence of protein-calorie malnutrition is high and mechanization is at a minimum, human labor provides much of the power for physical activity. This study presents anthropometric measurements, somatotypes, food intakes, energy expenditures, and work outputs of Oraon agricultural laborers of the Jalpaiguri district, West Bengal, in an attempt to identify the factors that predict high work productivity. Specifically, this study investigates 1) the relationship between morphological variation (anthropometric measurements and somatotype) and work productivity, 2) the nature and extent of the relationship between nutritional status and work productivity, and 3) the best predictor variables of work output. Classification of groups on the basis of median values of work output show that in the aggregate, the high productive groups are significantly younger than low-productive groups in both sexes. Before age-adjustment, the high productive groups show higher mean values of a few body dimensions, though these differ by sex, and both males and females exhibit a normal range of blood pressure and pulse rate values. Mean values of grip strength and back strength are higher in high-output men and women. Mean values of both food intake and energy expenditure are also higher among men in high-output groups, with only food intake higher in high-output women. However, after eliminating the effects of age, the differences between low-productive groups and high-productive groups in most of the variables are not significant. Productivity predictors in males consist of age, food intake and chest girth (inhalation). Females, on the other hand, show age and grip strength (left) as work output predictors.

Digit ratio (2D:4D) and handgrip strength in subjects of Han ethnicity: Impact of sex and age

The ratio of the length of the second finger to the fourth finger (2D:4D) is considered to be a putative proxy of prenatal exposure to testosterone, and has been increasingly used as a promising tool to evaluate the impact of prenatal androgenization in humans in such traits as physical performance. In this study, for the first time, we present 2D:4D data on adult participants of Han ethnicity. We consider the sexual dimorphism of 2D:4D and handgrip strength, and also report the relationship between 2D:4D and handgrip strength of males and females. The sample consisted of 54 males and 55 females recruited from a remote village in the Qinling Mountains, China. We found sexual dimorphism of both 2D:4D and handgrip strength, i.e., males had lower 2D:4D and right‐left 2D:4D than females and greater handgrip strength than females. There was a sex‐specific correlation between 2D:4D and handgrip strength, i.e., 2D:4D in the right hand was negatively correlated with handgrip strength in males but not in females. This relationship may be driven by sexual selection operating on fetal programming. Am J Phys Anthropol 149:266–271, 2012. © 2012 Wiley Periodicals, Inc.     

Digit Ratio (2D:4D) and Handgrip Strength in Hani Ethnicity

Introduction

The ratio of the length of the second finger to the fourth finger (2D:4D) in humans is considered as a putative marker of prenatal exposure to testosterone, and has been progressively adopted as one useful tool to evaluate the effect of prenatal hormones in some traits such as physical ability. Handgrip strength is one authentic measure of physical ability and is generally used on the anthropological research within an evolutionary viewpoint.

Methods

Here we present the first evidence on 2D:4D and handgrip strength on adult participants of Hani ethnicity and explore the relationship between digit ratio (2D:4D) and handgrip strength. We examined 2D:4D and handgrip strength of 80 males and 60 females at Bubeng village, in the Yunnan province of China.

Results

The mean 2D:4D in females was higher than that in males for each hand. Females showed significantly higher 2D:4D than males in the right hand rather than in the left hand. Males displayed significantly higher handgrip strength than females for both hands. Handgrip strength decreased with age for both sexes. A significant negative correlation between 2D:4D and handgrip strength was found in the right hand of males.

Conclusion

The relationship between 2D:4D and handgrip strength may be attributed to evolutionary drive of sexual selection operating on fetal programming.

Sex- and age-related variations of the somatotype in a Chuvasha population.

The aim of this large, cross-sectional study was to describe the age- and sex-related variations of the somatotype, employing Heath and Carter's method, in a Chuvasha population residing in a rural region in central Russia. The investigated sample included 802 males aged 18-89 years (mean 46.9) and 738 females aged 18-90 years (mean 48.6). We evaluated the age and sex differences by one-way ANOVA with somatotype components as dependent variables and sex or age groups as grouping variables. Sex differences of somatotypes appear to be the strongest for endomorphy, with generally higher values in women. Endomorphy in males remained virtually unchanged after 30 years of age, but endomorphy in females kept increasing up to the 6th decade, and then subsequently decreased. Virtually no differences were noted in mesomorphy and a very small difference in ectomorphy between males and females aged 18-30 years. A reduction of sexual dimorphism in all somatotype components after age 70 was also observed. The largest difference of all somatotype components appeared between age groups 18-30 and 31-40 years. Thereafter, somatotypes remained practically unchanged. Mesomorphy continued to increase until the 5th decade in both sexes, while in females, endomorphy continuously increased until their 6th decade. In the 7th and 8th decades, a decrease in mean values was observed. Mesomorphy and ectomorphy showed opposite age-related trends. Results of our study clearly suggest that in physique investigations, the somatotypes need to be studied in each sex separately, and in studies of young people, they need also to be adjusted to age.
