    Abstract This study aimed to search for relations between body fat percentage and skin temperature and to describe possible effects on skin temperature as a result of fat percentage in each anatomical site. Women (26.11±4.41 years old) (n =123) were tested for: body circumferences; skin temperatures (thermal camera); fat percentage and lean mass from trunk, upper and lower limbs; and body fat percentage (Dual-Energy X-Ray Absorptiometry). Values of minimum (TMi), maximum (TMa), and mean temperatures (TMe) were acquired in 30 regions of interest. Pearson's correlation was estimated for body circumferences and skin temperature variables with body fat percentage. Participants were divided into groups of high and low fat percentage of each body segment, of which TMe values were compared with Student's t-test. Linear regression models for predicting body fat percentage were tested. Body fat percentage was positively correlated with body circumferences and palm temperatures, while it was negatively correlated with most temperatures, such as TMa and TMe of posterior thighs (r =−0.495 and −0.432), TMe of posterior lower limbs (r =−0.488), TMa of anterior thighs (r =−0.406) and TMi and TMe of posterior arms (r =−0.447 and −0.430). Higher fat percentages in the specific anatomical sites tended to decrease TMe, especially in posterior thighs, shanks and arms. Skin temperatures and body circumferences predicted body fat percentage with 58.3% accuracy (R =0.764 and R2 =0.583). This study clarifies that skin temperature distribution is influenced by the fat percentage of each body segment.

    Abstract It is well known that body composition can influence peripheral heat loss and skin temperature. That the distribution of body fat is affected by gender is well known; however, there is little information on how body composition and gender influences the measure of skin temperature. This study evaluated skin temperature distribution according to body fat percentage (BF%) and gender. A sample of 94 apparently healthy volunteers (47 women and 47 men) was assessed with Dual-Energy X-Ray Absorptiometry (DXA) and infrared thermography (mean, maximum and minimum temperatures – TMean, TMax and TMin). The sample was divided into groups, according to health risk classification, based on BF%, as proposed by the American College of Sports Medicine: Average (n = 58), Elevated (n = 16) or High (n = 20). Women had lower TMean in most regions of interest (ROI). In both genders, group High had lower temperature values than Average and Elevated in the trunk, upper and lower limbs. In men, palms and posterior hands had a tendency (p < 0.05) for increased temperature along with increased BF%. TMean, TMax and TMin of trunk, upper and lower limbs were negatively correlated with BF% and the fat percentage of each segment (upper limbs, lower limbs and trunk). The highest correlations found in women were between posterior trunk and BF% (rho = −0.564, p < 0.001) and, in men, between anterior trunk and BF% (rho = −0.760, p < 0.001). Overall, this study found that women have lower skin temperature than men, which was related with higher BF%. Facial temperature seems not to be influenced by body fat. With the future collection of data on the relationship between BF% and skin temperature while taking into account factors such as body morphology, gender, and ethnicity, we conclude that measurement of BF may be reliably estimated with the use of thermal imaging technology.

    Abstract O Pediasuit que tem como objetivos o reforço muscular, resistência, flexibilidade, equilíbrio, coordenação e o desenvolvimento motor. Para avaliar a eficácia do tratamento pode-se utilizar o baropodômetro que é uma plataforma que visa detectar alterações posturais na posição estática, disfunções no equilíbrio e estabilidade. Neste sentido, o objetivo deste estudo foi verificar a influência do método Pediasuit na postura e controle motor de crianças com paralisia cerebral por meio da baropodometria. Foi realizado um estudo de caso descritivo, com uma criança do sexo feminino de três anos e com diagnóstico clinico de paralisia cerebral, apoiado pelo diagnóstico funcional, por meio da escala GMFM. O tratamento foi realizado durante quatro semanas, quatro horas por dia, cinco vezes por semana. O teste com o baropodômetro foi realizado três vezes: antes, durante e depois da aplicação do protocolo. Constatou-se, em relação à distribuição de carga plantar máxima, um resultado satisfatório, sendo que no início do tratamento o plano anterior recebia uma carga de 58% e o posterior 42% ao final deste demonstrou uma carga de 49% no plano anterior e 51% no posterior. Conclui-se que houve uma melhora na distribuição de carga plantar nos planos de ante e retro pé, sugerindo dessa forma que o método pode ser considerado eficaz.

    Abstract OBJETIVO: Comparar o ultrassom (US) portátil e a bioimpedância elétrica (BIA) com as dobras cutâneas (DC) para estimar o percentual de gordura corporal em adultos. MÉTODOS: Foram avaliadas 195 militares, sexo masculino, sendo coletados: peso, estatura, percentual de gordura por bioimpedância, dobras cutâneas e ultrassom (US) em nove pontos (tríceps, subescapular, bíceps, peitoral, médio axilar, abdominal, suprailíaca, coxa e panturrilha). Além da estatística descritiva, foram utilizados gráficos de dispersão, o teste Kolmogorov-Smirnov, coeficiente de correlação π (rho) de Spearman, o Wilcoxon Signed Ranks Test e a regressão linear para a elaboração de uma nova equação para a estimativa do percentual de gordura corporal em adultos jovens (do sexo masculino). RESULTADOS: O grupo apresentou idade média de 23,07 ± 7,55 anos, para peso e estatura os valores da média e desvio padrão foram: 72,65 ± 10,40 kg; 1,74 ± 0,06 metros, respectivamente. Comparando os resultados entre US e DC, verificaram-se correlações significativas para todos os pontos avaliados, sendo a prega da coxa a com maior correlação, seguida pelo peitoral. Comparando-se os três métodos, o US apresentou melhor correlação com a BIA do que com as DC. Pode-se propor uma nova equação de estimativa do percentual de gordura por US, que apresentou uma melhor correlação com o método das DC do que aquela utilizada pelo próprio equipamento. CONCLUSÃO: Foi possível verificar que na população estudada o US e a BIA podem estimar o percentual de gordura corporal com boas correlações com o método da DC.

    Abstract ABSTRACT Introduction: The increase in the prevalence of obesity entails the need for accurate low-cost methods to estimate body fat percentage (BF%). Objective: The aim of this study was to develop mathematical models to estimate the BF% of young women from southern Brazil using inexpensive equipment, based on body circumferences (BC), considering the shortage of specific studies of this population. Methods: Subjects were women (n=130) aged 18 to 35 years (26.06±4.41 years), from the city of Curitiba. Body mass and stature were measured and used to estimate body mass index (BMI), while BC measurements of the arm, forearm, waist (narrowest point and umbilicus), abdomen, hip, thigh and leg were taken for use in the mathematical models. Dual-Energy X-Ray Absorptiometry (DXA) equipment recorded the BF%. Pearson’s correlation was used for anthropometric variables and age in association with BF%. The indicators with best correlations were used to estimate linear regression mathematical models for prediction of BF%. The results of the two models and of nine anthropometric equations were compared to those obtained with the DXA using Pearson’s correlation coefficient and paired t-test. Results: Age was not significantly correlated with BF% (r=0.113 and p=0.200). The BCs with the highest correlations with BF% were abdomen, hip and waist - umbilicus (r=0.697, 0.682, 0.660, respectively, and p<0.001). Eight equations showed positive correlation with BF%, but only the results obtained with the models estimated in this study did not differ from those of DXA, with paired t-test. Mathematical models were developed with three (r=0.744, r²=0.554; t=0.16 and p=0.869) and six (r=0.768, r²=0.591; t=-0.04 and p=0.967) anthropometric variables. Conclusion: The use of mathematical models developed for estimating BF% based on body circumference and body mass is considered feasible.

    Abstract ABSTRACT Introduction: Scoliosis is a three-dimensional deformity of the spine, characterized by a lateral shift that affects body posture. The Pilates Method (PM) promotes alterations in the biomechanics and neuromuscular activation pattern. Objective: The aim of this study was to analyze electromyography (EMG) and symmetrography (SMTG) technologies applied in the evaluation of neuromuscular and postural effects on right convex thoracolumbar scoliosis (RCTS) after applying a PM therapeutic protocol. Methods: This is an exploratory study of 5 male and female adolescents, with an average age of 14.4 years. The subjects underwent postural asymmetry assessments through SMTG and neuromuscular assessment through surface EMG of the trapezius (TRAP), erector spinae (ERE), oblique (OBLI) and rectus abdominis (RA) muscles. The electromyographic signals were processed in the temporal (EMGAmp) and spectral (EMGFmed) domains. The therapeutic protocol consisted of 24 sessions of Pilates floor exercises held twice a week with a duration of 45 minutes. Results: There was an improvement in scoliosis and asymmetric shoulders in one subject (20%) and in three other subjects with hip asymmetry. There was an improvement in one subject (33.33%), as demonstrated by SMTG. EMGAmp measurements demonstrated a significant difference between before and after (p≈0) and among the muscles (p≈0). EMGFmed measurements demonstrated that there was only a difference between before and after (p≈0). It was verified that the most noteworthy muscles in terms of EMGAmp were TRAP and ERE, emphasizing the existence of an increase in the mean EMGAmp for ERE. Muscle behavior for measurements in EMGFmed demonstrated a higher mean increase for RA and OBLI muscles. Conclusion: It is concluded that the EMG and SMTG technologies are important tests for monitoring the progress of scoliosis and in treatment decisions.
