Objective: To assess the quality of life, muscle strength and functional capacity in women with fi bromyalgia (FM). Patients and Methods: Cross-sectional study carried out with 31 female volunteers (age range, 35 to 60 years), paired in two groups (16 with FM, and 15 in the control group). Both groups underwent the following assessments: one-repetition maximum (1RM) of knee fl exors and extensors; quality of life (application of the SF-36 questionnaire); 6-minute walk test (6MWT); pinch strengths (tripod, pulp-to-pulp, and key) and handgrip strength. Results: A signifi cant difference between the groups was observed in the following variables: handgrip strength; pulp-to-pulp and tripod pinch strength of both hands; and the 1RM test of knee fl exors and extensors in both limbs (P < 0.05). Only the key pinch showed no statistical difference between groups for both limbs (P > 0.05). The 6MWT also showed a statistical difference between the groups (P < 0.01). The SF-36 showed that women with FM have reduced functional capacity, increased bodily pain, and worsened general health status (P < 0.05). Conclusion: The results revealed, in women with FM, a reduction in the following: muscle strength in the upper and lower limbs; the distance walked in the 6MWT; and quality of life.
Introduction: Basketball is one of the most popular sports involving gestures and movements that require single-leg based support. Dorsiflexion range of motion (DROM), balance and postural control may influence the performance of this sport. Objective: To compare and correlate measures of balance, postural control and ankle DROM between amateur basketball athletes and non-athletes. Methods: Cross-sectional study, composed by 122 subjects allocated into one control group (CG = 61) and one basketball group (BG = 61). These groups were subdivided into two other groups by age: 12-14 years and 15-18 years. The participants were all tested for postural balance with the Star Excursion Balance Test (SEBT), postural control with the Step-down test and DROM with the Weight-bearing lunge test (WBLT). Between-groups differences were compared using repeated-measures multivariate analysis of variance. Normalized reaching distances were analyzed and correlated with the WBLT and Step-down test. Results: There was no difference in the scores of WBLT (P = .488) and Step-down test (P =. 916) between the groups. Scores for the anterior reach (P = .001) and total score of SEBT (P = .030) were higher in BG. The values for the posterolateral (P = .001) and posteromedial reach (P = .001) of SEBT were higher in BG at the age of 15-18. The correlation between the anterior reach of the SEBT and WBLT was significant in BG between 12-14 years (r = 0.578, P = .008), and in the CG between 15-18 years (r = 0.608, P=.001). Conclusion: The balance was better in the BG, although adolescents between 15-18 years have better balance control for the posteromedial and posterolateral reaches of the SEBT.
<p>As argilas provenientes da Formação Corumbataí são atualmente a principal fonte de matéria-prima para as indústrias do Polo Cerâmico de Santa Gertrudes. 73% das indústrias desse polo que utilizam o processo de secagem via seca são hoje alvo de crescente pressão dos órgãos de controle ambiental devido à emissão de partículas (poeira) associado ao processo de secagem da matéria-prima. Neste trabalho, foram realizados quatro diferentes testes de secagem em três tipos de matéria-prima (D, I e M) da Formação Corumbataí, com umidades naturais iniciais de 8%, 18% e 19%, respectivamente, para poder avaliar a sensibilidade à secagem. Dentre os testes analisados neste trabalho estão o processo natural de secagem ao sol, secagem ao vento, secagem ao sol combinado a uma corrente de vento, e secagem ao sol com matéria-prima previamente umedecida em água corrente. Os testes foram ainda correlacionados à análise termogravimétrica. A análise por difração de raios X, juntamente com as análises química e petrográfica mostrou que as amostras D, I e M contêm predominantemente filossilicatos 2:1 como illitas (25-30%) e esmectitas (15-25%), e em menor quantidade caulinita (0-15%) e clorita (0-5%). Os resultados dos experimentos de secagem associados à mineralogia mostram que entre 100 °C e 200 °C nos gráficos de termogravimetria pode indicar de modo rápido a sensibilidade à secagem que o material apresenta, uma vez que a maior perda de umidade obtida nesta faixa indica a maior quantidade de minerais do grupo das esmectitas, que por sua vez conferem ao material menor sensibilidade à secagem. Além disso, os procedimentos de secagem natural sugerem que secar separadamente a matéria-prima pode resultar em maior eficiência do processo de secagem.</p>
The importance of the Santa Gertrudes Ceramic Complex (SGCC) in the ceramic market is directly associated with the high quality of the Corumbataí Formation clays used in the manufacture of its products. Although the volumetric capacity of the Corumbataí Formation is able to meet the SGCC demand for the coming years, its industries are always in search of alternative sources for raw material, among these sources is the Tatuí Formation. In order to determine if the sediments coming from the Tatuí Formation have the potential to be used in the ceramist industry, geochemical, mineralogical and physical characterization tests were carried out on samples obtained from two different profiles. The analyses showed a sequence of fine sandstones rich in SiO 2 and Al 2 O 3 , with a mineralogy composed of quartz, potassium feldspar / plagioclase (albite), filosilicates and iron oxides in secondary proportions. The ceramic tests, in turn, presented heterogeneous results for the specimens submitted to burning at 1150 º C, but in general, the material coming from the Tatuí Formation has a promising potential within the field of ceramic manufacturing.
