Objetivo:avaliar a força e o equilíbrio de mulheres com faixa etária superior a 50 anos, com quadro de osteoporose e praticantes de Pilates na cidade de Pirapora – MG.Materiais e Métodos:trata-se de um estudo de caráter descritivo e transversal, com amostragem por conveniência representada por 10 mulheres idosas com osteoporose praticantes de Pilates. Avaliou-se a força de membros inferiores através do teste de Sentar e Levantar, o equilíbrio estático através do teste Posição Flamingo e equilíbrio dinâmico através do testeTimed Up and Go.Resultados:o teste de Sentar e Levantar da Cadeira com média de 8,4±2,7 repetições indicou “zona de risco” para o desenvolvimento de dependência em atividades de vida diária. No teste Posição do Flamingo, os valores mais frequentes de oscilações fixaram-se ao nível “Forte” com 4,2±1,4 oscilações durante 60 segundo, indicando um bom desempenho. Já o testeTimed Up and Goapresentou média de 12,7±2,4 segundos para sua execução, apontam “baixo risco para quedas”.Conclusão:as mulheres idosas com osteoporose praticantes de Pilates apresentaram fraqueza de membros inferiores, mas bom equilíbrio estático e dinâmico. Mesmo com baixo risco de desenvolver quedas ainda permaneceram na “zona de risco” para adquirir dependência nas atividades diárias.

Objective: to identify and assess the occurrence of postural changes in children and adolescents,aged 11 to 14, in the final gradesof elementary school. Materials and Methods:an observational,descriptive, cross-sectional study, with quantitative data and samples composed by 24 children and adolescents froma private school in the city of Pirapora -MG. Postural behavior inside and outside theschool environment wasidentified through the application of the Postural Habit Assessment Questionnaire;children's static posture was assessed by means ofphotographs; andsymmetrography and biophotogrammetry analyses were held through Postural Assessmentsoftware tests. Results:good postural staticand dynamic habits in the school environment and a good perception of correct postures,whichmust be adopted standing or sitting, have been reported. However, postureanalysis by means ofthe software revealed the occurrence of scoliosis,being right-convex(50%) the mostfrequent;severe changes in the alignment ofthe shoulder girdle were shown in 41.7% of the sample. Conclusion:good postural habits and correct postural perceptions were reported. Even though, thesample related back pain and experienced similar complaints fromtheirparents at some point in life, in addition to showing static postural changes.

Objetivo:avaliar se a execução e prática do exercíciodeadlift stiffinfluenciam no desenvolvimento de dor lombar em mulheres de 20 a 40 anos praticantes de musculação.Materiais e Métodos:estudo de caráter observacional e descritivo, do tipo longitudinal, com análises quantitativas. Foi utilizado o Teste de Sentar e Alcançar proposto por Wells e Dillon, o teste de Kendall para a avaliação do desequilíbrio muscular de membros inferiores e a Escala Visual Analógica (EVA) para avaliar a intensidade de dor lombar.Resultados:Teste de Kendall e força do core apresentaram leve melhora. Teste do Banco de Wells e a flexibilidade também demonstram um leve aumento. Na Escala Visual Analógica da Dor, a dor lombar apresentou leve redução.Conclusão:a prática do exercíciodeadlift stiffnão influenciou no desenvolvimento dador lombar na amostra, mulheres praticantes de musculação e que o realizam com acompanhamento.

The aim of the present study was to investigate the effects of photobiomodulation (PBM) therapy on the expression of heat shock protein 70 (HSP70) and tissue repair in an experimental model of collagenase-induced Achilles tendinitis. Thirty Wistar rats (aged 12 weeks) were randomly distributed among control group (n = 8), tendinitis group (n = 11), and LED group (n = 11). Tendinitis was induced in the tendinitis and LED groups through a peritendinous injection of collagenase (100 μl). The LED group animals received the first irradiation 1 h after injury. A 630 ± 20 nm, 300-mW continuous wave light-emitting diode (LED), spot size 1 cm2, was placed in contact with the skin. One point over the tendon was irradiated for 30 s, delivering 9 J (9 J/cm2). LED irradiation was performed once daily for 7 days, with the total energy delivered being 63 J. The tendons were surgically removed and expression of the HSP70 protein was calculated using semi-quantitative analyses of immunohistochemistry (HSCORE). Number of fibroblasts and amount of collagen were measured using histological and histochemical analyses. An increase in the mean HSCORE for HSP70, in the number of fibroblasts, and in the amount of collagen were found in the LED group compared with those in the tendinitis and control group (P ≤ 0.05). PBM therapy increased the expression of the HSP70, number of fibroblasts, and amount of collagen in the acute Achilles tendinitis in rats.
