Holonomy Transformation in the FRW Metric

In this work we investigate loop variables in Friedman-Robertson-Walker spacetime. We analyze the parallel transport of vectors and spinors in several paths in this spacetime in order to classify its global properties. The band holonomy invariance is analysed in this background.Comment: 8 page

The effect of three different training programs in elderly women's isokinetic strength

This study aimed was to assess the effects of three different training protocols in quadriceps and hamstrings isokinetic muscle strength of independent elderly women. Eighty women were recruited for this study and divided intofour groups of twenty subjects: the control group, the multi-component group, the muscle power group,and the muscular resistance strength group. The isokinetic strength was measured in both lower limbs with a dynamometer at 60°/s and 180º/s. The multivariate analysis (ANOVA) and the Bonferroni test assessed the group and time effect. Significant and positive effects were observed in the time and group interaction in the power group at 180°/s and 60°/s knee flexion in the dominant (p = 0.004, respectively) and non-dominant (p = 0.046 and p = 0.041, respectively) lower limbs. The Control group had significantand negative effect on the time x group interaction at 180°/s and 60°/s on the extension of the dominant knee (p = 0.008 and p = 0.001, respectively) and non-dominant (p = 0.003 and p< 0.001, respectively). The muscle power training seems to be the most effective to increase the isokinetic strength in older independent women. All the training programs appear to contribute to decreasingthe age-related loss on isokinetic strength.This study was developed in the Research Centre on Physical Activity Health and Leisure (CIAFEL) that is supported by Pest-OE/SAU/UI0617/2011info:eu-repo/semantics/publishedVersio

The effects of daily physical activity on functional fitness, isokinetic strength and body composition in elderly community-dwelling women

Physical inactivity has been classified as a public health problem. The excess fat with muscle loss along with the general decline of physical and functional capacity. The aim of this study was to evaluate the relative contribution of objectively estimated daily physical activity (PA) in functional fitness, isokinetic strength and body composition in community-dwelling elderly women. Sixty elderly female volunteered for this research, with 67.69 ± 5.30 years old. Daily PA was assessed using accelerometers for 7 days. The evaluation and quantification of body composition, total lean body mass, fat mass, total body fat mass and bone mineral density, were made with the DXA equipment. Body Mass Index (BMI) was also calculated. The functional fitness (FF) assessment was performed using Functional Fitness Test. The knee extensor and flexor isokinetic strength was evaluated in both lower limbs, using a dynamometer at two different angular velocities: 60°/sec. and 180°/sec. Body Composition, Bone Mineral Density (p = 0.014) and Fat Mass (p = 0.029) were statistically lowers in the 3rd tertile compared to the 2nd one. The knee flexion peak torque at 180°/sec on the dominant leg (p = 0.051) and non-dominant leg (p = 0.020) was statistically different between the less active group and the most active group. For the FF, no significant differences between groups were found. Our results suggest that daily PA seems to induce benefits on BMI and % Fat Mass as well as on isokinetic knee flexion strength of independent and community dwelling-resident’s older women.This study was developed in the Research Centre on Physical Activity Health and Leisure (CIAFEL) that is supported by Pest-OE/SAU/UI0617/2011info:eu-repo/semantics/publishedVersio

Los efectos de tres tipos diferentes de entrenamiento en la aptitud funcional y la composición corporal en mujeres mayores

The aim of this study was to assess the effects of three different training protocols with 8 months in functional fitness and body composition of elderly women. Material and methods: Eighty community- dwelling elderly women were randomly divided into four groups: (i) control group (68.55 ± 5.24 years); (ii) multicomponent training group (68.70 ± 6.51 years), (iii) muscle power training group (66.30 ± 3.87 years) and finally, (iv) resistance training group (67.10 ± 5.46 years). A total body scan in dxa equipment assessed the body composition. The functional fitness (ff) was evaluated with the functional fitness test. A multivariate analysis (anova) with repeated measures on each dependent variable allowed to detect differences in each group and time. The bonferroni test allowed to assess the group x time interaction. Anova revealed no significant effect on time x group interception in body composition variables. Results: A significant effect on intercept time x group in tests of upper body flexibility in control group (p=0.028), multicomponent training group (p=0.001) and muscle power training group (p=0,002) and lower body flexibility multicomponent training group (p<0.001), muscle power training group (p=0.003); and resistance training group (p=0.002); aerobic endurance in multicomponent training group (p<0.001); upper body strength in multicomponent training group (p=0.005), muscle power training group (p=0.008) and resistance training group (p=0.007) and lower body strength in multicomponent training group (p=0.045) and muscle power training group (p=0.006) were founded. Discussion: Our study suggests that, independently of type of training, independent community-dwelling elderly women should improve their functional performance with appropriate exercise programs. Conclusion: We can conclude that 8 months training programs did not induce significant changes to body composition. However, changes in ff were observed.info:eu-repo/semantics/publishedVersio

Curvas de classe de qualidade provisórias de povoamentos de pinheiro bravo da Serra da Estrela

No presente trabalho apresentam-se curvas classe de qualidade provisórias para os povoamentos de pinheiro bravo da região da serra da Estrela. Como não se dispunha de sucessões cronológicas de alturas optou-se pelo emprego do método das curvas proporcionais. Para o ajustamento da curva guia ensaiaram-se os seguintes modelos: função de KORSUN, função de HOSSFELD, função de SCHUMACHER e uma parabola do 2.° grau. De acordo com a precisão dos resultados obtidos escolheu-se a função de SCHUMACHER. Ficou demonstrado que o uso da versão simplificada desta (k=l) não provoca diminuição apreciável da precisão final obtidainfo:eu-repo/semantics/publishedVersio

Índices de concorrência na elaboração de modelos de produção florestal

O autor apresenta os índices de concorrência (competição) mais recentes. Trabalhando com povoamentos jovens (6-39 anos de idade) de pinheiro silvestre, localizados na Baviera, foi-lhe possível estabelecer uma estreita correlação entre o crescimento em altura e a pressão de concorrência sofrida! por cada árvore. O autor calcula, para os seus povoamentos, diferentes índices espaço de crescimento (2.2.2.), apresenta um índice baseado na concorrência entre copas (2.2.3.2.), propõe diferentes adaptações (2.3.3.) do índice de concorrência do modelo de Hegyi (1974) e ensaia o índice de concorrência (2.4) de Assmann (1975). Foram seleccionados, pela sua alta correlação com o crescimento em altura da árvore individual, os índices espaço de crescimento e as diferentes adaptações do índice de concorrência do modelo de Hegyi (1974)info:eu-repo/semantics/publishedVersio
