Esse estudo analisou os efeitos de 10 semanas de treinamento contra resistência, sobre a composição corporal, a força muscular e a flexibilidade de 11 mulheres idosas (68,91 ± 5,43 anos). Um grupo de 8 idosas (65,13 ±4,09 anos) serviu como controle inativo. A força de preensão manual (ambas as mãos), o percentual de gordura corporal (dobras cutâneas e bioimpedância) e a flexibilidade (teste "sentar e alcançar") foram avaliados antes e após 10 semanas. A força muscular isotônica foi avaliada pelas cargas de treinamento. Após as avaliações iniciais, os indivíduos começaram o programa de treinamento que consistiu de oito exercícios (peito, costas, ombro, bíceps, tríceps, coxa, panturrilha e abdome), sem a realização de exercício para flexibilidade. O programa de treinamento resultou em aumentos significativos (p< 0,001) na força muscular isotônica, para todos os exercícios, com aumentos percentuais que variaram de 25,91% a 49,09%, para tríceps e panturrilha, respectivamente. Verificaram se aumentos significativos (p < 0,001) na força de preensão manual de ambas as mãos e também na flexibilidade no grupo submetido a treinamento. O programa de treinamento não resultou em alteração na gordura corporal avaliada por bioímpedância e equação de dobras cutâneas...

O objetivo deste estudo foi comparar os níveis de adiposidade subcutânea dos hemicorpos direito e esquerdo e, posteriormente, analisar o impacto dessas informações para o estudo da composição corporal. Setenta e seis indivíduos fisicamente ativos, 47 homens (21,6 ± 4,3 anos) e 29 mulheres (21,0 ± 2,6 anos), fizeram parte da amostra. As espessuras das dobras cutâneas abdominal, suprailíaca, subescapular, tricipital, bicipital, axilar média e perna medial foram mensuradas com um compasso Lange. Em valores médios absolutos, as maiores diferenças verificadas foram de 0,9mm (6,9%) e 0,8mm (6,8%), na dobra cutânea suprailíaca de homens e mulheres, respectivamente. Entretanto, nenhuma diferença estatisticamente significante foi encontrada na comparação entre os lados, em ambos os sexos, nas sete dobras cutâneas analisadas (P > 0,05). Similarmente, quando os valores medidos foram aplicados em equações preditivas para a determinação da gordura corporal relativa, de acordo com o sexo, nenhuma diferença significante foi encontrada (P > 0,05). Os resultados sugerem que fatores como o erro técnico de medida do avaliador, o tipo de compasso e a escolha da equação preditiva a ser utilizada, provavelmente tenham maior impacto para a estimativa da composição corporal pelo método de espessura de dobras cutâneas do que o lado a ser adotado como referência para a obtenção das medidas.; The aim of this study was to compare subcutaneous adiposity levels of right and left sides and posteriorly to analyze the impact of this information to the body composition study.

The aim of the present study was to analyze the anthropometric changes in a home-based cohort of Brazilian older adults who participated in the SABE Survey, conducted in 2000 and 2006. A total of 1030 men and women were examined by age group: 60-69, 70-79, and ≥80 years. This representative sample consists of the survivors of the 2000 cohort. The following anthropometric variables were assessed: body mass, arm muscle, waist and calf circumferences, triceps skinfold thickness, body mass index, waist-hip ratio, and arm muscle area according to mean values and percentile distribution. Except for body mass and body mass index, a significant difference (P<0.05) was observed among the assessed anthropometric variables during the follow-up period. The older adults ≥80 years presented the lowest values. The reduction in the mean values of triceps skinfold thickness was greater (30%) than that of waist circumference (9%) and was more pronounced in women (21%) than in men (9%). Arm muscle circumference and area reduced by 8% and 19%, respectively, in men and 1% and 3%, correspondingly, in women. Our findings revealed reductions in the mean values for all anthropometric variables in the follow-up period from 2000 to 2006 among older adults. © 2013 Manuela Ferreira de Almeida et al.

STUDY OBJECTIVE: To determine the relationship between obesity and subsequent incidence of ischaemic heart disease (IHD). DESIGN: Prospective cohort survey. SETTING: Study of three occupational groups, with follow up examinations. SUBJECTS: 3500 people recruited between 1972 and 1978 (80% response rate), and followed up between 1978 and 1984. This report is based on subgroup of 1511 white men aged 40-64 at entry. MEASUREMENTS AND MAIN RESULTS: Information was obtained on smoking and family history of IHD. Blood pressure, weight, height, skinfold thickness at four sites, fibrinogen, factor VII activity and cholesterol were measured during follow up. Body mass index (BMI) was used as an index of obesity. BMI was found to be more strongly correlated with IHD than any of the skinfold measurements, none of which was significantly associated with IHD when BMI was allowed for. Increase in BMI by 1 SD (approximately 8 kg) was associated with a 44% increase in the risk of IHD. Of the four skinfolds, subscapular was the most closely associated with risk, confirming the relevance of central obesity. The association between obesity and IHD remained when possible mechanisms for its effects were taken into account, and its strength may increase with time: for 1 SD increase in BMI...

Standards of triceps and subscapular skinfold thicknesses for 1293 Caucasian newborn infants of gestational ages 37-42 weeks, and of 0-25 kg birthweight intervals between 2-25 and 4-5 kg are presented. Female infants had a greater skinfold thickness than males, and the subscapular skinfold was greater than the triceps. The skinfold thickness in both males and females declined after 40 weeks of gestation.

Height, weight, and selected skinfold measurements were taken on 544 Michigan males and 557 females age 18 and over. Mean body weight showed a tendency to increase with age for both sexes up to age 64 while mean height progressively decreased from its maximum at age 18-24 years. Between ages 18 and 64 years, mean triceps skinfold thickness of men increased 10 per cent, female triceps skinfolds 50 per cent. Mean subscapular skinfold values rose consistently with age for both sexes. Comparison of these findings with those from earlier national studies suggest that Michigan adults are heavier and fatter but no taller than other US adults.

Skinfold standards provide a useful indication of subcutaneous fat. To evaluate skinfold thickness of 252 Cambridge infants over the first 2 years of age, SD scores relative to the Tanner standards were calculated, taking account of skewness in the standards. Cambridge SD scores were low, varying according to age from −1.2 to −1.8 for triceps and −0.6 to −1.2 for subscapular skinfolds. The Tanner skinfold standards were last revised 30 years ago, at a time of high prevalence of infantile obesity, and the present and other studies indicate that infants are now thinner. There is a need for new skinfold standards to reflect this change. Since the Cambridge infants contributed to the recent British height and weight references, it is suggested that their skinfold measurements could also serve as reference points.

Total body water was estimated as part of the assessment of body composition in children with growth disorders, using the newly commercially available method of bioelectrical impedance. This was undertaken to compare the precision and accuracy of the results with those derived from skinfold thickness against measurement of stable isotopically labelled water (H2(18)O) dilution as a standard. The comparisons were carried out to see to what extent the impedance method could be applied with confidence to assessment of children with growth disorders. Total body water was derived from impedance (I) using an association with height (Ht2/I). Impedance and skinfold thickness estimates of total body water were equally precise when compared with values obtained from H2(18)O dilution (limits of agreement -1.9 to +1.3 and -1.7 to +2.0 kg respectively). The mean intraobserver coefficient of variation for repeat measurements of impedance was 0.9% compared with 4.6% for skinfold thickness with an interobserver coefficient of variation for impedance of 2.8%. Bioelectrical impedance estimation of body composition is likely to be of value in the growth clinic when expertise in measurement of skinfold thickness is limited or repeated measurements are to be undertaken by different observers.

The objective of the study was to develop prediction equations for fat-mass percentage in infants in India based on skinfold thickness, mid-arm circumference, and age. Skinfold thicknesses and mid-arm circumference of 46 apparently-healthy infants (27 girls and 19 boys), aged 6–24 months, from among the urban poor attending a well baby clinic of a hospital in Kolkata were measured. Their body-fat percentage was measured using the D2O dilution technique as the reference method. Equations for body-fat percentage were developed using a stepwise forward regression model using skinfold thicknesses, mid-arm circumference, and age as independent variables, and the body-fat percentage was derived by D2O dilution as the dependent variable. The new prediction equations are: body-fat percentage=-69.26+5.76×B-0.33×T2+5.40×M+0.01×A2 for girls and body-fat percentage=-8.75+3.73×B+2.57×S for boys, where B=biceps skinfold thickness, T=triceps skinfold thickness, and S=suprailiac skinfold thickness all in mm, M=mid-arm circumference in cm, and A=age in month. Using the D2O dilution technique, the means (SD) of the calculated body-fat percentage were 17.11 (7.25) for girls and 16.93 (6.62) for boys and, using the new prediction equations, these were 17.11 (6.25) for girls and 16.93 (6.02) for boys. The mean of the differences of paired values in body-fat percentage was zero. The mean (SD) of the differences of paired values for body-fat percentage derived by the D2O technique and the new equations...

The objective of this study was to describe and compare the tricipital (TSF) and subscapular skinfold (SSF) thickness according to demographic, socioeconomic, behavioral, and biological characteristics in adolescents from Pelotas, Rio Grande do Sul State, Brazil. A cross-sectional study nested in a birth cohort (n = 4,452; mean age = 11 years) was conducted. The outcomes were defined as skinfold thickness ??? 90th percentile of the National Center for Health Statistics reference curve. The prevalence rates for elevated TSF and SSF were 20.2% and 17.3%, respectively, in boys and 14.2% and 10.5% in girls. The strongest factor associated with adiposity in boys was socioeconomic status (p < 0.001), whereas among girls it was maternal body mass index (p < 0.001). Low physical activity (< 300 minutes/week) was associated with elevated SSF only among girls, while schooling was associated with increased TSF and SSF only among boys. Diet, skin color, and sedentary behavior were not associated with any of the outcomes. We concluded that the main predictors of adiposity were maternal and socioeconomic characteristics. We recommend that further studies on this issue apply other methods to estimate body composition in order to confirm our results.; O objetivo deste estudo foi descrever e comparar as pregas cut??neas triciptal (PCT) e subescapular (PCS) de acordo com caracter??sticas demogr??ficas...

We explore relationships between BMI and skinfolds and anthropometric variables reflecting variation in lean body frame. Data on the middle class adult Australian women (n = 1260) collected in 2002 during a National Body Size and Shape Survey were used. Standard measurements of stature, weight, skeletal dimensions (shoulder width, hip width, chest width, and depth, limb lengths), circumferences of head, trunk, limbs and triceps, subscapular and abdominal skinfolds were taken. Techniques for measurements of skeletal frame minimized the inclusion of adipose tissue thickness. Analysis of variance and parametric and nonparametric correlations were used. Vertical dimensions show weak correlations with fatness, while body frame circumferences and transverse dimensions are consistently, significantly, and substantially correlated with fatness, each explaining from 3 to 44% of variation in skinfold thickness. Skeletal dimensions explain up to 50% of variation in skinfold thickness (multiple regression). Especially high correlations with skinfold thickness occur for chest width, depth, and hip width (r range from 0.42 to 0.66). Body frame dimensions reflect largely trunk volume and the trunk/limb proportions. Larger lean trunk size is associated with greater fatness. Since the size of the abdominal cavity...

Background: It is estimated that between 34% and 50% of Australian women entering pregnancy are overweight and obese, which is associated with an increased risk in complications for both the woman and her infant. Current tools used in clinical and research practice for measuring body composition include body mass index (BMI), waist circumference and bioimpedance analysis. Not all of these measures are applicable for use during pregnancy due to a lack of differentiation between maternal and fetal contributions. While skinfold thickness measurement (SFTM) is increasingly being used in pregnancy, there is limited data and a lack of a standard tool for its use in overweight and obese pregnant women. Methods: We developed a standard tool for evaluating SFTM among women with a BMI ≥ 25 kg/m2. Forty-nine women were measured as part of a prospective cohort study nested within a multicentre randomised controlled trial (The LIMIT Randomised Controlled Trial). Two blinded observers each performed 2 skinfold measurements on the biceps, triceps and subscapular of each woman. Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were used to analyse SFTM, body fat percentage (BF%) and inter-observer variability. Results: The ICC for inter-observer variability in measurements were considered moderate for biceps SFTM (ICC = 0.56) and triceps SFTM (ICC = 0.51); good for subscapular SFTM (ICC = 0.71) and BF% (ICC = 0.74); and excellent for arm circumference (ICC = 0.97). The standard error of measurements ranged from 0.53 cm for arm circumference to 3.58 mm for the subscapular SFTM. Conclusion: Our findings indicate that arm circumference and biceps...

BACKGROUND: Subcutaneous adipose tissue may influence the transmission of electrical stimuli through to the skin, thus affecting both evoked torque and comfort perception associated with neuromuscular electrical stimulation (NMES). This could seriously affect the effectiveness of NMES for either rehabilitation or sports purposes.OBJECTIVE: To investigate the effects of skinfold thickness (SFT) on maximal NMES current intensity, NMES-evoked torque, and NMES-induced discomfort.METHOD: First, we compared NMES current intensity, NMES-induced discomfort, and NMES-evoked torque between two subgroups of subjects with thicker (n=10; 20.7 mm) vs. thinner (n=10; 29.4 mm) SFT. Second, we correlated SFT to NMES current intensity, NMES-induced discomfort, and NMES-evoked knee extension torque in 20 healthy women. The NMES-evoked torque was normalized to the maximal voluntary contraction (MVC) torque. The discomfort induced by NMES was assessed with a visual analog scale (VAS).RESULTS: NMES-evoked torque was 27.5% lower in subjects with thicker SFT (p=0.01) while maximal current intensity was 24.2% lower in subjects with thinner SFT (p=0.01). A positive correlation was found between current intensity and SFT (r=0.540, p=0.017). A negative correlation was found between NMES-evoked torque and SFT (r=-0.563...

Skinfold thickness was measured at five sites in 750 infants. The study population was unselected except that twin pregnancies and the infants of diabetic mothers were excluded, and very preterm infants were under represented. A pilot study had indicated that skinfold measurement was most reproducible at the thigh site. Thigh skinfold correlated better with the sum of other skinfolds than did skinfold measurement at any other site and closely resembled the summed skinfold in correlations with a number of maternal and fetal variables. Median skinfold increased with birthweight and was greater in girls than in boys. 'Corrected skinfold', a mathematical approach to comparing skinfolds in infants of differing sex and birthweight, is suggested as an alternative to absolute skinfold measurement.

Skinfold thickness is an index of subcutaneous fat, and certain maternal conditions during pregnancy affect the skinfold thicknesses of the baby. A study was performed to investigate the effect of smoking on skinfold thickness, maternal weight gain, and fetal size at birth. A total of 452 mothers with normal singleton pregnancies were groups as: non-smokers, light-to-moderate smokers, or heavy smokers. Maternal age, height, parity, and duration of pregnancy were similar in the three groups. Heavy smokers gained significantly less weight than non-smokers, but there was no significant difference in skinfold thickness. Babies born to smokers had lower birth weights and smaller head circumferences and were shorter than those born to non-smokers, but skinfold thicknesses were similar. The presence of a normal layer of subcutaneous fat in babies whose mothers smoked suggests that fetal growth retardation is not caused by nutritional deficiencies.

Field-based assessments provide a cost–effective and accessible alternative to dual-energy X-ray absorptiometry (DXA) for practitioners determining body composition in athletic populations. It remains unclear how the range of physical impairments classifiable in wheelchair sports may affect the utility of field-based body composition techniques. The present study assessed body composition using DXA in 14 wheelchair games players who were either wheelchair dependent (non-walkers; n = 7) or relied on a wheelchair for sports participation only (walkers; n = 7). Anthropometric measurements were used to predict body fat percentage with existing regression equations established for able-bodied persons by Sloan and Weir, Durnin and Womersley, Lean et al, Gallagher et al, and Pongchaiyakul et al. In addition, linear regression analysis was performed to calculate the association between body fat percentage and BMI, waist circumference, sum of 6 skinfold thickness and sum of 8 skinfold thickness. Results showed that non-walkers had significantly lower total lean tissue mass (46.2 ± 6.6 kg vs. 59.4 ± 8.2 kg, P = 0.006) and total body mass (65.8 ± 4.2 kg vs. 79.4 ± 14.9 kg; P = 0.05) than walkers. Body fat percentage calculated from most existing regression equations was significantly lower than that from DXA...

OBJETIVO: Validar métodos de estimativas da gordura corporal (somatória de espessura de dobras cutâneas, circunferência da cintura (CC) e razão cintura-quadril (RCQ)) em portadores do HIV/Aids, tendo como padrão ouro a absortometria por dupla emissão de raios-X (Dexa) e a tomografia computadorizada de abdômen (TCA). MÉTODOS: Foram estudados 15 portadores do HIV/Aids tratados em uma unidade de saúde coligada a um hospital público universitário, São Paulo. Foram medidas a gordura subcutânea total (GST) mediante a somatória da espessura de sete dobras (bíceps, tríceps, subescapular, axilar média, supra-ilíaca, abdominal e panturrilha medial), a gordura subcutânea central (GSC) (somatória da espessura de quatro dobras) e a gordura subcutânea de membros (GSM) (somatória da espessura de três dobras). A GST, GSC e GSM foram comparadas com as medidas de gordura obtidas pela Dexa. A CC, a RCQ e a GSC foram comparadas com as medidas de gordura obtidas pela TCA. Na análise estatística, utilizou-se o coeficiente de correlação de Pearson (r) e foi utilizado o teste de Mann-Whitney. RESULTADOS: A gordura medida pela Dexa foi correlacionada com GST, a GSC e GSM, mesmo após o ajuste pela idade (r>;0,80 para todos). A gordura total de abdômen medida pela TCA foi correlacionada com a CC...

Com isso, o objetivo do presente estudo foi, através de uma revisão crítica, comparar estudos que avaliaram as técnicas de pregas cutâneas e impedância bioelétrica para estimar a composição corporal de atletas. Foram revisados estudos publicados de 1990 a 2007, identificados “on line” através dos bancos de dados PubMed, SportDiscus e Scielo. Para qualificar os estudos, sete elementos críticos foram avaliados: número de participantes, nível dos atletas estudados, métodos estatísticos empregados, uso de diferentes equações, controle dos testes, controle da amostra e método de referência. Como ferramenta na avaliação da composição corporal de atletas, IB e PC apresentam muitas vantagens em relação a outros métodos, principalmente, quanto à facilidade de aplicação, por ser um método não invasivo de determinação e de preço razoavelmente barato. A exatidão e confiança de resultados obtidos por esses métodos são altamente dependentes das condições do teste...

 http://dx.doi.org/10.5007/1980-0037.2008v10n1p1The present study was designed to determine the level of agreement between four widely used skinfold-thickness equations and body mass index-based prediction equations (%BFBMI) for evaluating body fat percentage in university students. A total of 431 subjects (174 females and 257 males) aged 18-30 years old were included in the study. Skinfoldthickness equations proposed by Jackson and Pollock, Durnin and Womersley, Petroski and Guedes and Guedes were included in the study. The %BFBMI was predicted using Deurenberg’s age-and-sex specifi c equation. For the assessment of agreement, the paired t test, intraclass correlation coeffi cients and Bland-Altman plots were computed for the correlation between predicted percentage body fat according to each skinfold-thickness equation and %BFBMI. The results showed that the mean values of percent body fat predicted by each skinfold-thickness equation and from body mass index did not differ signifi cantly. Intraclass correlation coeffi cients ranged from 0.463 to 0.612. The Bland-Altman analysis indicated that the mean differences were close to zero, especially in males, but demonstrated a limited individual capacity of agreement, with upper and lower confi dence limits at -13.5% and 1.0%...

The sample was composed by 93 children aged 6 to 10 years and of both sexes, living at the villages Kaxinawá do Caucho e Paroá, in the state of Acre, Brazil. Body adiposity was estimated by skinfold thickness at triceps and subscapular sites and by the sum of these two skinfolds. Nutritional status was identified by the indicators weight-for age (w/a), stature-for-age (s/a) and weight-for-stature (w/s) using z-score cut-off points suggested by the World Health Organization. For comparison between sexes, the Student’s t-test was used. Low body fat prevalence was observed in 83.7% of boys and 62% of girls. There were significant differences between sexes at 8 and 10 years of age for the triceps skinfolds and the sum of skinfolds. For the subscapular skinfold, the difference was observed only at 8 years of age. Chronic malnutrition was detected in both sexes and the prevalence depended upon the applied criteria. The prevalence was 76.3% for s/a and 47.3% for w/a. Acute malnutrition was present among 12.9% of children when using w/s. Boys tended to have higher prevalence for chronic malnutrition (s/a and w/a)...
