ABSTRACT
A Força de Preensão Manual (FPM) é uma medida bastante utilizada na prática clínica como um indicador de saúde, por representar a força muscular global. O objetivo deste estudo foi analisar os coeficientes de concordância entre dinamometria e diferentes equações antropométricas preditoras da força de preensão manual em idosos. Trata-se de um estudo transversal baseado nos dados da pesquisa epidemiológica de base populacional e domiciliar. Participaram do estudo 283 (85,8%) idosos, residentes na zona urbana do município de Lafaiete Coutinho, com idade > 60 anos. A força de preensão manual foi mensurada por meio da dinamometria e estimada por diferentes equações antropométricas: Tveter et al., Novaes et al., e Fortes et al. As medidas antropométricas utilizadas no estudo foram: peso e estatura. O coeficiente de Lin e os gráficos de Bland Altman foram usados para observar concordância da FPM entre as equações. A média de idade dos idosos foi de 73,8±8,9 anos, peso corporal 60,11 ± 12,54 Kg, estatura média foi 154,83 ± 9,1 cm e IMC 25,05 ± 4,7 kg/m2 . Para os coeficientes houve moderada concordância nas equações antropométricas de Fortes 0,62 (0,55 0,68), Novaes 0,60 (0,53 0,66) e Tveter 0,60 (0,53 0,65) comparada a dinamometria, respectivamente. As equações antropométricas utilizadas para estimar a força de preensão manual apresentaram moderada concordância com o método padrão ouro (dinamometria)....(AU)
The handgrip strength (HGS) is a measure widely used in clinical practice as a health indicator, to represent the overall muscle strength. The aim this study was to analyze the concordance coefficients between dynamometry and different anthropometric equations predictor handgrip strength of elderly. This is a cross-sectional study that analyzed data from epidemiological research of a home and population-based epidemiological survey. Participated in the study 283 (85,8%) elderly people, living in the urban área of the municipality of Lafaiete Coutinho, aged > 60 years. Handgrip strength was measured using dynamometry and different anthropometric equations: Tveter et al., Novaes et al., and Fortes et al. Anthropometric measurements used in the study were: weight and height. The Lin coefficient and the Bland Altman graphics were used to observe the HGS concordance between the different equations. The mean age of the elderly was 73.8 ± 8.9 years, mean body weight was 60.11 ± 12.54 kg, mean height was 154.83 ± 9.1 cm and BMI 25.05 ± 4.7 kg/m2 . For the coefficients there was moderate concordance in the anthropometric equations of Fortes 0,62 (0,55 0,68), Novaes 0,60 (0,53 0,66) e Tveter 0,60 (0,53 0,65) compared to dynamometry, respectively. The anthropometric equations used to estimate the handgrip strength showed moderate concordance with the gold standard test (dynamometry)....(AU)

OBJECTIVE: The aim of this study was to evaluate the multisegmental static postural balance of active eutrophic and obese elderly women using a three-dimensional system under different sensory conditions. METHODS: A cross-sectional study was conducted on 31 elderly women (16 eutrophic and 15 obese) aged 65 to 75 years. The following anthropometric measurements were obtained: weight, height, waist and hip circumference, and handgrip strength. The physical activity level was evaluated using the International Physical Activity Questionnaire. Body composition was measured using the deuterium oxide dilution technique. The Polhemus® Patriot (three-dimensional) equipment was used to measure the parameters of postural balance along the anteroposterior and laterolateral axes. The data acquisition involved one trial of 60 s to test the limit of stability and four trials of 90 s each under the following conditions: (1) eyes open, stable surface; (2) eyes closed, stable surface; (3) eyes open, unstable surface; and (4) eyes closed, unstable surface. RESULTS: For the limit of stability, significant differences were observed in the maximum anteroposterior and laterolateral displacement (p<0.01) and in the parameter maximum anteroposterior displacement in the eyes closed stable surface condition (p<0.01) and maximum anteroposterior and laterolateral displacement in the eyes open unstable surface (p<0.01 and p = 0.03) and eyes closed unstable surface (p<0.01 and p<0.01) conditions. CONCLUSIONS: Obese elderly women exhibited a lower stability limit (lower sway area) compared with eutrophic women, leaving them more vulnerable to falls.
